Its been 10 years since the beta release of EFFs HTTPS Everywhere web browser extension. It encrypts your communications with websites, making your browsing more secure. HTTPS has journeyed its way from an urgent recommendation to a main component of traffic of our everyday web experience. In 2018, we discussed the importance of HTTPS Everywhere and our ongoing effort to encrypt the web. We have come far and still have more work to do. This post gives a snapshot into the landscape of HTTPS Everywhere today.
Since the launch of HTTPS Everywhere, other projects have also taken on the task of helping users browse securely. These more recent projects include DuckDuckGos Smarter Encryption and Smart HTTPS. The biggest difference is that HTTPS Everywhere still operates a community-curated list of rules for particular sites. Many users who add to our list have intimate knowledge of the sites they are contributing. Examples of such reports include subdomains of a site that have misconfigurations, insecure cookies, or CDN buckets to account for.
Many users wanted dynamic upgrades to HTTPS, so we developed the Encrypt All Sites Eligible (E.A.S.E) mode in HTTPS Everywhere.
EASE automatically attempts to upgrade connections from insecure HTTP to secure HTTPS for all sites, and prevents unencrypted connections from being made. This parallels the features of the more recent projects listed. EASE mode also assists in preventing downgrade attacks, where malicious actors attempt to redirect your browser to an insecure HTTP connection to the site. This is handled slightly differently by other projects, but we want to emphasize that our rulesets also apply to sub resources on the page as well. Meaning, if there are images and scripts that link to another domain, such as a Content Delivery Network (CDN), our rules can apply to those as well. We are not only adding rulesets, but amending them as websites change. HTTPS Everywheres maintainers and contributors have done a fantastic job over the years maintaining this aspect of the project.
A common question is whether HTTPS Everywhere is still helpful if DNS over HTTPS (DoH) is enabled? Absolutely. The Domain Name System (DNS) looks up a sites IP address when you type the sites name into your browser. A DNS request occurs before the sites server connection is made; DoH occurs at this layer. After the DNS request has been made, the connection to the sites server is next. That is where HTTPS Everywhere comes in: it is able to secure your traffic to the requested site.
DNS request = request for I.P. sites address
HTTP request = request communication with site's server/website content
DoH & HTTPS = encrypted request for sites I.P. & encrypted request with site's server/website content respectively
Many browsers have made important strides in adopting HTTPS at a more aggressive rate. For example:
We hope to see these developments, especially the option to be HTTPS by default, in both Firefox and Chrome.
In the coming decade, we hope browsers will further help to encrypt the web. Its time for browsers to close these remaining gaps and give users the choice to upgrade to HTTPS. We hope our HTTPS Everywhere project will eventually not be needed in its current state, because the browsers themselves will close these gaps. This will take a strong commitment by all major browsers to provide comprehensive HTTPS options for their users.
In addition to encrypting your web traffic, HTTPS Everywhere also provides extended features that have made way for some exciting developments in internet privacy.
Our update channels provide a secure way for other parties to load their own rulesets. For example, SecureDrop partnered with Tor to use HTTPS Everywhere Update channels to have human-readable onions in Tor Browser! As SecureDrop explains:
SecureDrop uses onion servicesaccessible only via the Tor networkto protect sources sending tips to news organizations. When you visit an onion service (address ends with .onion), all traffic to and from the service is encrypted and anonymized.
We are excited to be able to provide a platform for easily shared AND secure tips to newsrooms. A very big hat tip to SecureDrop and Tor Browser.
Learn more about Rust + Web Assembly: https://rustwasm.github.io/docs/book/introduction.html
This project and its extended features were created to make privacy and security not only accessible but easily obtainable to everyone. Anonymity and privacy on the web shouldnt be limited to people with highly technical knowledge. Hopefully when we write an update a decade from now, HTTPS Everywhere will be retired, because its encryption safeguards will have been fully integrated as a common feature of the net.
Thank you for using HTTPS Everywhere. If you havent installed it, do so today!

10 Years of HTTPS Everywhere - EFF

Safari, Explorer, Chrome these are some of the most popular internet browsers ever. But theyre not necessarily the safest.
With rates of cybercrime steadily rising, you should arm yourself with all the tools you can. And there are browsers out there that were built with your security in mind.
Before we begin the list, we must define what we mean by security in this context. Generally speaking, were talking about which browsers protect your information, your privacy and take steps to keep you safe from security breaches. In no particular order, here are some of the best options:
You probably werent expecting such a mainstream browser to kick off this list, but Firefox can be a very safe option. You just need to tweak it.
Within the browsers settings, you can modify your Privacy and Security settings to standard, strict, or custom. And there are plenty of guides online that can help you customize your settings.
For example, you can customize your settings to block content that tracks the sites you visit and profiles you.
You even have the option to make sure specific websites dont track you.
There are numerous plug-ins, like Decentraleyes and uBlockOrigin, that can add extra layers of safety and security. Just make sure you use a trusted guide, as some modifications can cause some websites to become inaccessible or can slow download speeds.
If you like Firefox but want to up your security game even further, check out Tor Browser. Its basically a fortified version of Firefox.
Another branch of the Firefox tree, Brave was founded in 2016 by former Mozilla head Brenden Eich. As part of its standard protection features, Brave protects against fingerprinting, blocks trackers and ads, upgrades to HTTPS (which protects against eavesdropping and tampering), and has a built-in script blocker.
Fingerprinting is when sites scrape together specific information about you and your computer, which they use to create ads for you and can block you from identifying frauds or avoiding harmful bots, according to The Washington Post.
Brave also allows you to select what data you want to delete every time you close the app.
The browser has drawn criticism by including its own ads on websites while blocking ads from competitors.
But all in all, Brave is a good option. The browser fully transferred over to Chromium codebase, allowing easy use of Chrome extensions.
Its all in the name. Security and privacy are this browsers main goal. Unlike Mozilla, Epic defaults to the highest security setting. It may make some websites inaccessible, but if youre serious about security, this could be the browser for you.
Epic deletes all traces of history as soon as the app is exited. All third-party cookies are blocked. It hides your IP address, making a VPN unnecessary.
It claims to block 600+ tracking attempts per session, in addition to blocking ads and fingerprinting.
While these browsers might be some of the safest and most secure, none can guarantee safety.
If you feel like your security has been breached, do not hesitate to reach out to one of our trusted professionals. And if you want to add an extra layer of security, consider proactively adding one of our digital protection plans.

In August, the young artificial intelligence process automation company Intelenz, Inc. announced its first U.S. patent, an AI-enabled software-as-a-service application for automating repetitive activities, improving process execution, and reducing operating costs. For company co-founder Renzo Zagni, the patent is a powerful testament to the value of his MIT educational experience.
Over the course of his two-decade career at Oracle, Zagni worked his way from database administrator to vice president of Enterprise Applications-IT. After spending seven years in his final role, he was ready to take on a new challenge by starting his own company.
From employee to entrepreneur
Zagni launched Intelenz in 2017 with a goal of keeping his company on the cutting edge. Doing so required that he stay up to date on the latest machine learning knowledge and techniques. At first, that meant exploring new concepts on his own. But to get to the next level, he realized he needed a little more formal education. Thats when he turned to MIT.
When I discovered that I could take courses at MIT, I thought, What better place to learn about artificial intelligence and machine learning? he says. Access to MIT faculty was something that I simply couldnt pass up.
Zagnienrolled in MIT Professional Educations Professional Certificate Program in Machine Learning and Artificial Intelligence, traveling from California to Cambridge, Massachusetts, to attend accelerated courses on the MIT campus.
As he continued to build his startup, one key to demystifying machine learning came from MIT Professor Regina Barzilay, a Delta Electronics professor in the Department of Electrical Engineering and Computer Science and a member of MITs Computer Science and Artificial Intelligence Laboratory. Professor Barzilay used real-life examples in a way that helped us quickly understand very complex concepts behind machine learning and AI, Zagni says. And her passion and vision to use thepower of machine learning to help win the fight against cancer was commendable and inspired us all.
The insights Zagni gained from Barzilay and other machine learning/AI faculty members helped him shape Intelenz early products and continue to influence his companys product development today most recently, in his patented technology, the "Service Tickets Early Warning System. The technology is an important representation of Intelenz ability to develop AI models aimed at automating and improving business processes at the enterprise level.
We had a problem we wanted to solve and knew that artificial intelligence and machine learning could possibly address it. And MIT gave me the tools and the methodologies to translate these needs into a machine learning model that ended up becoming a patent, Zagni says.
Driving machine learning with innovation
As an entrepreneur looking to push the boundaries of information technology,Zagni wasnt content to simply use existing solutions; innovation became a key goal very early in the process.
For professionals like me who work in information technology, innovation and artificial intelligence go hand-in-hand, Zagni says.
While completing machine learning courses at MIT, Zagni simultaneously enrolled in MIT Professional Educations Professional Certificate Program in Innovation and Technology. Combining his new AI knowledge with the latest approaches in innovation was a game-changer.
During my first year with MIT, I was putting together the Intelenz team, hiring developers, and completing designs. What I learned in the innovation courses helped us a lot, Zagni says. For instance, Blake Kotellys Mastering Innovation and Design Thinking course made a huge difference in how we develop our solutions and engage our customers. And our customers love the design-thinking approach.
While his progress at Intelenz is exciting, Zagni is anything but done. As he continues to develop his organization and its AI-enabled offerings, hes looking ahead to additional opportunities for growth.
Were already looking for the next technology that is going to allow us to disrupt the market, Zagni says. Were hearing a lot about quantum computing and other technology innovations. Its very important for us to stay on top of them if we want to remain competitive.
He remains committed to lifelong learning, and says he will definitely be looking to future MIT courses and he recommends other professionals in his field do the same.
Being part of the MIT ecosystem has really put me ahead of the curve by providing access to the latest information, tools, and methodologies, Zagni says. And on top of that, the faculty are very helpful and truly want to see participants succeed.

Machine Learning and Artificial Intelligence to Revolutionize the World of Art and Creativity – Entrepreneur
Posted: at 9:48 pm
November10, 20204 min read
Artificial intelligence is revolutionizing various industries, markets, and services. However, the creative industries and the art world have not yet been able to use the full potential of this technology. However, two Chilean entrepreneurs devised a platform to go further.
Using the latest technology, they allow creators, amateur filmmakers, visual artists, even the film and music industry to use artificial intelligence algorithms in their work. This is Runway , a platform that integrates machine learning and artificial intelligence to the world of art and creativity.
Founded at the end of 2018 by Cristbal Valenzuela, Alejandro Matamala and Anastasis Germanidis, Runway started as a thesis project that they developed at New York University (NYU) - where they met - while developing a postgraduate degree.
Its creators define the platform as part of the new generation of creative tools. If Photoshop and Adobe revolutionized the creative market a few decades ago, Runway is looking to do so for years to come.
In this case, the bet of this startup is that with their software in the cloud, they can develop "synthetic content", that is, automatically generate, modify, and edit audiovisual content with artificial intelligence algorithms.
Cristobal, Alejandro and Anastasis, founders of Runway. Courtesy photo
"We continue to create audiovisual content in the same way that we have done for decades and that makes the process unnecessarily slow, expensive and difficult. With AI algorithms anyone can create hyper-realistic animations in seconds and edit them automatically. Something that only Hollywood or large production companies and special effects have been able to do so far, "explains Valenzuela.
At the same time, Runway makes it possible to shorten development times, in addition to democratizing access to this technology for as many creators as possible. These technologies are radically changing the way we create content because algorithms are already capable of generating images, text, video and sound in an ultra-realistic way, explains Cristbal; to which Alejandro adds "if we put these tools in the hands of people who have never accessed them before, they will start to think of new ways of producing art, generating content and telling stories".
The impact of the platform started from when they launched a tweet asking how many would use a tool like the one they had in mind. In less than 48 hours, they already had responses from engineers from Facebook, Google, universities and even the media, indicating that they found the possibility of a creative tool to occupy artificial intelligence algorithms incredible. Immediately after this, they created the company and have not looked back.
The path they have already traveled has been fast. As a result of their work, they have already generated interest from different investment funds. In the same year that they created Runway, they completed a $ 2 million investment round with US funds specialized in technology research startups: Lux Capital, Amplify Partners Compound Ventures.
But also, on a practical level, they have already carried out important projects, such as a collaboration with New Balance for the design of a shoe; be the software with which the rock band YACHT created part of the audiovisual content of their latest album - being nominated for a Grammy Award; be working on the creation of short films generated by IA, and even already collaborating with visual artists and the seventh art.
Along with this, the response of cloud software has also come from the academic world, which has led them to close alliances with various universities in the United States, such as NYU, MIT and UCLA; while in Chile the software is already being used at the Universidad Adolfo Ibez, Universidad de las Amricas, and the Pontificia Universidad Catlica.
At the moment, each step that Runway takes is a path towards the future and that is precisely the bet that its founders are making, by developing residencies or internships in the company for artists and researchers, so that they can deepen the uses and applications of the technology they develop. This was a practice that they had implemented before the outbreak of the coronavirus pandemic and that they will resume in a few more weeks, from their offices located in Brooklyn in New York City.

The ever-increasing adoption of AI-powered systems in all areas of the economy could either lead to potential discrimination against women or open up new career prospects. Lets find out what needs to be done to achieve the second scenario.
For years, there have been debates that artificial intelligence will change the labor market. Nowadays the focus has shifted from the inevitability of the future to an assessment of how and when the world will change and what it means for all of us. There have been several attempts to create AI, but Artificial General Intelligence the one portrayed in films and books is still a long way from being built. What do we have now?
There are many narrow smart algorithms that solve niche tasks and can find patterns in large amounts of data.They help to make decisions on, for example, whether a suspicious transaction should be stopped or allowed, where cargo should be sent, or whether a loan should be granted.The probability of a mistake in these systems is lower comparing to a human beings performance.Further development of algorithms capable of supplementing or replacing human decision-making will reduce the number of roles requiring routine decision-making, which are often taken on by women. It is already difficult to imagine a bright future of tour operators, taxi dispatchers, clerks, and some other professions. According to a forecast made by IMFresearchers, 11% of jobs held by women will be automated within the next two decades. The focus will also shift into designing these algorithms.
More and more decisions are made automatically and, sadly, not in womens favor. For example, two years ago Amazon, the largest online retailer in the world, was forced to dismiss an automated CV-reviewing system because it discriminated against female developers.This situation occurred because the data used to train machine learning models represented a hiring history for 10 years. At that time, the majority of candidates were male, but this does not prove that men are better at technical work.Considering that algorithms are becoming in charge of making an ever-increasing number of decisions, similar side effects can be an issue.
It is widely believed that algorithms just find patterns within an existing data set. However, focusing on data, it is easy to forget two aspects of this problem: the limitations of existing algorithms and, more importantly, the role of people who train them. Most algorithms just catch the correlation within the data, without understanding anything about it. Even the best data is meaningless as long as people who can solve problems and ask the right questions are not involved, so the algorithms will simply reflect our own biases.
Developers of AI systems must carefully monitor the way datasets are formed and track any biases that might occur.Mistakes made by the algorithm should be tracked: sometimes the percentage of errors is quite low, but they could be related to one group of people.For example, a scoring model systematically refuses to give loans to residents of Chinatown. Such behavior is particularly dangerous because we are shifting more and more responsibility for decision-making onto the system. Some advanced algorithms which are currently in use cannot even be interpreted; i.e. we are unable to understand why a certain decision has been made at all, or which factors influenced it.
Its interesting to note that the rise of computer science is strongly connected with women:Ada Lovelace created programming, Betty Holberton designed the first general-purpose computer, and Margaret Hamilton developed the software for the Apollo project.Today, only15% of specialists in the field of artificial intelligence around the world are women, which is disappointing for many advocates of gender equality.Some people worry that the future will be created by men for men.The presence of female analysts eases the situation since they can spot the problems with products that are not easy to discover if you dont face discrimination on a daily basis.
Women already spend a lot of energy ensuring that they are treated honestly and fairly. Perhaps a legal base is needed. Some regulatory bodies have already taken up this issue. For example, the EU General Data Protection Regulation (GDPR) requires companies to explain the reasons behind decisions made by AI systems and to monitor them to prevent any discrimination. Currently, only large companies and governments can afford the software and hardware required to launch the most advanced AI models. This barrier could be used to help set up some basic rules before the technology becomes widely used.
Many futurists are optimistic about womens chances of success. Why? The most valuable skills in this brave new world are those that algorithms cannot master: the use of soft skills and emotional intelligence. As such, 83% of organizations surveyed byCapgemini believe that emotional intelligence will be a prerequisite for success in the coming years. The new labor market will value compassion, multi-tasking, cooperation, and empathy traits that are traditionally associated with women, meaning that women will have greater chances of being hired. However, there is a nuance here. To succeed in an AI-ruled world, a great work of retraining and adaptation is necessary. After all, it will be not the strongest and intelligent that survives, it is the one that is most adaptable to change.
Extra risks for women will be caused by an inability to adapt.The new challenges of automation are added to conventional difficulties, creating barriers to gender equality. Nowadays there is a need for mobility and flexibility among employees as it is now easier to change profession, employer, industry, and even country than ever before. Women are often less mobile than men, because of their second job at home. Whats more, they are oftenexcluded from networking, which allows men to improve their skills, find mentors, and new employment opportunities.
On the other hand, companies will be more motivated to push their employees to develop skills that cannot be automated. If women are proactive and able to adapt, they will have more employment opportunities.Bear in mind that being good at something no one needs is the biggest waste of time. In the future, two categories of skills will be most important: the ability to negotiate and standing your ground, and the ability to see trends and build strategies.
Organizations need employees who can talk to both machines and people. Recently, technologies have been significantly democratised, meaning that you do not need a PhD to work with AI.Today is the best time to gain insight on the foundations of a technology which at first seems complicated, even if your profession is not connected with data analysis at all.
It would be useful for executives to at least make themselves comfortable with the methods of machine learning for analyzing different types of data. Such analysis will make it possible to assess use cases for AI implementation in a specific area and to build an effective strategy for digital transformation. A deep dive into the topic and acquisition of practical skills, such as programming and creating machine learning models, will be useful for those who spend a lot of time running routine analysis and who want to automate the decision-making process.
Implemented projects from industries that are more mature when it comes to AI adoption, such as IT companies, banks, and retailers, can be good sources of inspiration. Even such a conservative industry as manufacturing has started digital transformation programs for production optimization, for example, to forecast machinery breakdowns.
According toIDC forecasts, by 2021 AI systems will be implemented in one form or another at 75% of enterprises. So, the relevant skills will be required in almost all industries. Allocate an hour and watch a video on the principles of machine learning. Only by having a clear understanding of how it works, it is possible to ask the right questions and set goals. Knowledge of a few principles is more important than understanding detailed implementation ways for all algorithms in a software package.
Once you understand the basic principles, its important to understand which tasks are the most relevant for applying AI and to try delegating some responsibilities to the machine to increase the quality of work and performance. By studying successful scenarios of AI application, many people realize that this technology can be used for a wide range of processes and tasks that involve working with large amounts of data.Women should learn how to find prospective use cases for new technologies, have sufficient motivation to look for answers, and take under control their education and career.
Data analysis skills are relevant to a huge number of professions, from marketing experts to mechanics working with a CNC machine. For example, AI can identify anomalies in a technological process. Currently, there is a lack of personnel in data science and artificial intelligence space. The problem is so urgent that large companies are offering free platformsfor studying. After the training, you may not be able to perform as good as an experienced data scientist, but you will be able to translate a task from a business domain for the researcher, for example, regarding an analysis of CV-collection or even writing music.
According to the Institute of Electrical and Electronics Engineers, an international non-profit association of specialists in the field of computer science, The need for specialists in artificial intelligence has revealed itself in almost every area of life. Experts are urging for AI training for specialists in areas such as healthcare, agriculture, and logistics.
Conventional methods of working are rapidly becoming obsolete. Humanity has to choose once again: to lament about fate and talk about the rise of the machines or to get ready for the future and acquire the skills that are in demand. The Luddites have lost in their fight against the machines, simply because machines are economically efficient. And, as we know now, after all the number of jobs created thanks to the adoption of machines has been far greater than the number of jobs gone.
The most insightful employees were not afraid of industrialization, and made use of and reaped the benefits of new technologies. So, why cant women do the same?

Today, artificial intelligence (AI) applications are reshaping large and small companies products, services, and business models. Decision makers need to make critical hardware and software choices to achieve AI strategy success. As smaller firms to global enterprises assess their business cases and work flows the need for highly-scaled servers and cloud platforms are no longer the only option to build a successful AI infrastructure.
The study results summarized in this white paper, Using Workstations To Reshape Your Artificial Intelligence Infrastructure, show that firms are already using workstations to lower the cost, increase the security, and speed up their AI infrastructure. The addition of workstations into a firms AI workflow allows servers and cloud platforms to be tasked with business cases that require more robust computing while workstations take on tasks with longer time frames and smaller budgets.
Download this white paper, Using Workstations To Reshape Your Artificial Intelligence Infrastructure, to read more about how highly-scaled servers and cloud platforms are necessary to run applications that must be run at top speed and where cost is not a barrier. However, workstations provide excellent support for applications where data security is a priority but where timelines are more flexible or cost is a major consideration.

Automation during the industrial revolution led to a profound change in working practices across the 18th and 19th centuries. Currently, we are in the midst of a fourth industrial revolution, with globalisation and automation affecting every aspect of our working lives and leisure activities. The COVID-19 pandemic has provided a further driver for change, altering how we work and interact with remote working and reduction of human interaction at the centre of global initiatives to try and reduce the spread of the virus.
Healthcare systems generate large quantities of complex datasets pertaining to patients. Artificial Intelligence (AI) can offer solutions to medical problems by attempting to replicate decisions that would otherwise require human intelligence. Specific algorithms can be created in order to make associations between data and predict future outcomes. The COVID-19 pandemic has accelerated change within healthcare systems and driven interest in automated algorithms capable of assisting hospitals in diagnostics, decision making and repetitive clerical tasks thus reducing the potential footfall of staff on site. Automation and intelligent algorithms that learn and improve with further iterative cycles require data and the ethics behind large personal data sets, the challenges of anonymisation remain in their infancy.
AI applications within healthcare can be broadly categorised into diagnosis, research, management and system analysis. Ultimately in the time of COVID, workforce adaptations have led healthcare providers to use their workforce wisely, reducing the staff requirements on site and moving towards remote working.
Healthcare records in most countries have moved from paper-based records and notes to digital media. The electronic health record (EHR) allows the capture of large quantities of data across patient groups. Future patient care aims to develop tailored treatments for patients in a cost-effective manner.
The use of large datasets requires an element of data curation. Data needs to be retrieved from multiple disparate data sources. Data needs to then be cleaned to remove anomalies and harmonised to ensure similar data sets are compared across patient records. An element of these processes needs human oversight to ensure the correct data is fed into the algorithms.
Administrative applications are resource-heavy and repetitive. These applications include workflow management such as uploading referral letters from primary care, setting up referral assessment services and booking patients to the correct service provider in secondary care. Robotic process automation (RPA) consists of computer programmes that obey rules for these manual, resource-heavy tasks.
Additionally, process management systems (PMS), while embedded within commercial businesses, are still in their infancy within a healthcare application. Patients are individuals and tailoring care to them necessitates being able to react to changing physiological parameters within the confines of the organisation. In order to standardise care, clinical pathways have been developed to manage patient care from referral, to ordering diagnostic tests and eventual treatment pathway. While standardisation across patient groups allows for automation of some of these processes (templates for referral, standard test orders), allowing a more tailored approach which is patient-specific is the ultimate goal; thus generating a conflict to resolve between standardisation and a tailored patient approach specific to their individual needs.
Flexibility within a process management system requires technological skills to allow tasks to be postponed or reorganised. However, healthcare professionals lack the technical skillset to implement this, requiring a user-friendly interface. Further work in user interface and user experience (UI/UX) is therefore required to ensure a system that allows flexibility without losing the advantages of rapid automation and processing of large numbers of patients within the pathway management systems.
Increasingly call centre staff for websites have been replaced by chatbots that use natural language processing (NLP) to provide callers with information and manage queries. A chatbot is a type of AI programme that can conduct an intelligent conversation via text or auditory methods. It is predicted that by 2025 the global chatbot market will be worth $1.23bn. For hospitals dealing with upwards of 10,000 patient appointments per week, the use of chatbots to handle patient queries regarding appointment queries is still in its infancy when compared to more established sectors such as banking or commerce.
The current COVID-19 pandemic has highlighted the need for rapid screening and testing of patients to improve treatment pathways and also reduce the risk of cross infection. Clinical testing requires taking biological samples from patients which can be resource heavy and incorporates a time lag before results are available from real-time polymerase chain reaction testing (RT-PCR). The use of AI within this environment accessing electronic health records (EHR) of routinely ordered tests and vital signs can produce an effective tool to screen patients in emergency departments and hospital admission units.
Predictive analytics utilise AI algorithms to analyse healthcare data from EHRs to predict future outcomes thus aiming to improve outcomes and the patient experience as well as reducing costs. Data collected from EHRs can be supplemented with data from wearable technology and medical devices. Risk prediction models utilising AI would improve with successive data collection cycles aiming to supplement decision making by clinicians. Applications include management of chronic diseases such as chronic renal failure, diabetes and cardiovascular disease. Specific patient populations can vary across geographical healthcare providers and the ability of a predictive model to learn from its local population provides an advantage over established static modelling. Scalability across healthcare providers can therefore be challenging due to differences in socio-economic factors and populations based on geographical location. The ethical implications in terms of health insurance and risk stratification are in their infancy; and issues around data governance and data sharing may have a significant impact that is yet to be fully regulated.
Diagnostic applications of AI technological advances have exploded over the past ten years with multiple applications. Imaging studies such as breast mammograms or histological analysis rely on skilled scientists or clinicians performing repetitive tasks to manually identify abnormalities. An inaccurate diagnosis can have serious consequences for patient care. AI programmes can be trained to perform these tasks and have shown an accuracy in correctly diagnosing abnormalities which in some studies has been shown to be as accurate as a trained clinician. Further future applications in diagnostic imaging include the field of radiomics which extracts nuanced features peculiar to imaging modalities such as wavelength, texture and shape. This additional information can provide further data for diagnosis and prognostic indicators specific to patients.
With the potential application of AI within the healthcare setting, the question remains how will this impact the workforce? The fourth industrial revolution has 50% of companies to predict that by 2022, automation will decrease their numbers of full-time staff and that by 2030 robots will replace 800 million workers across the world (McKinsey Global Institute reports). Automation of clerical processes and care pathways could potentially impact on the non-clinical workforce within a healthcare setting. Specialties such as radiology where imaging reports can be automated and produced by AI algorithms may soon be the reality. The ethics of data sharing and the implications for patients and their insurers is a further area of controversy. We enter a brave new world.

The Breadth Of Healthcare Applications Of Artificial Intelligence Even Includes Physical Therapy – Forbes
Posted: at 9:48 pm
This column keeps returning to the healthcare industry because it is so much more complex and varied than so many others. Artificial intelligence (AI) coverage has focused on radiology, has moved to the operating theater, and has been discussed in the back office. Insurance and pharma fraud are arenas where AI risk analysis is useful. Now, along comes another area that is amenable to AI solutions. Its something many people think of as secondary, but is really a critical part of healthcare: physical therapy.
As someone who, many years ago, had an intriguing car crash, and who, not as many years ago, also proved he wasnt as young as he thought he was, by blowing out a knee, Im someone who is very aware of the need for physical therapy (PT). The basics of PT seem very simple: design therapies that cause repeated motions of damaged body parts, analyze that motion, then provide feedback to the patient and the medical community in order to help both improve. Its the capture and analysis of impact (yes, pun intended) of that motion which can prove complex.
Human physical therapists can see a lot of movement, but its impossible for them to capture all the necessary information. SWORD Health is a company focused on this unique healthcare segment. As they are a young company, they are focusing on a few key therapy areas. The hip, knee, lower back, shoulder, wrist and neck comprise more than 90 percent of all musculoskeletal issues in the U.S., said Virgilio Bento, CEO, SWORD Health. Rehabilitating them remotely requires a technology that can learn and expand.
One intriguing area that supports a separate call out section is the oft problematic issue of bias in testing. We know that visual neural networks have had problems identifying women of color. We know that, outside of AI, many drug trials dont include children, pregnant women, and other demographics who will need those drugs. Physical therapy is a healthcare sector that can avoid those problems.
There is already a body of PT information on the wide variety of demographics who receive PT. The ability to track far more information and to analyze it with demographic information (even anonymized for privacy), means that treatments can start with far more segmentation based on available information and then been quickly tuned on an individual basis based on direct, specific results. Starting with patterns based on more detailed segmentation and then transforming treatment on a case-by-case basis removes the bias issues that may be inherent in other areas of medicine or even in the minds of some medical personnel.
As has been regularly mentioned, AI is a tool, not a solution. The company isnt only working with machine learning. They make sensors to capture the information, with the kinematics being sent to the system via wireless communications. Then multiple techniques can be used to address the data. A mixture of deep learning and statistical linear regression is used to understand the progress of the therapies. Changing the therapy can then also be semi-automated, with the system suggesting changes. That doesnt need deep learning, as choosing the therapies is a rules based process.
As with all areas of healthcare dealing with patients, in the United State the FDA requires clearance of both new and updated appliances. The difference between hardware and AI is readily apparent with how each part is handled on change. When a hardware component is changed, detailed specifications can be sent to the FDA for fairly quick analysis and approval. The regulatory agency is still early in its analysis on how to manage AI, especially neural networks, so the process can be slower than with hardware.
AI is still a grey area, primarily through the fault of AI companies. While they like to talk about the black box that is a neural network, for instance, they know their layers, they know the nodes, the code and the weightings. While some of the inference is still not easily explicable, there is far more companies could provide to regulatory agencies if it were mandated.
In the lack of such transparency, expect for at least near-term job security for humans. They must remain in the loop, both as oversight for the AI and as a legal cover to say the AI is not making a prognosis but is providing the humans with options.
Deep learning and other machine learning techniques have an important place in healthcare, but it must be incorporated into the full patient treatment process, along with other technology. Unlike a deep learning system cranking along on its own in a research facility, investigating potential new drugs, AI must play well with other technology and processes the closer to patients it resides. Physical therapy is an excellent aspect of the needed growth, as it is a regular and visible part of patient treatment that includes humans, hardware and software interacting within a regulatory framework to improve patient outcomes.
Vatican Library Enlists Artificial Intelligence to Protect Its Digitized Treasures – Smithsonian Magazine
Posted: at 9:48 pm
Since 2010, the Vatican Apostolic Library has worked to digitize its sprawling collection of more than 80,000 manuscripts, making a trove of rare historical treasures freely accessible to anyone with an internet connection.
But the tricky work of uploading the contents of the Roman Catholic Churchs historic library comes with new risks in the digital age. As Harriet Sherwood reports for the Observer, the library recently hired cybersecurity firm Darktrace to defend its digitized vault against attacks that could manipulate, delete or steal parts of the online collection.
Founded by University of Cambridge mathematicians, Darktrace uses artificial intelligence (A.I.) modeled on the human immune system to detect abnormal activity in the Vaticans digital systems, writes Brian Boucher for artnet News. On average, the A.I. system defends the library against 100 security threats each month, according to a Darktrace statement.
The number of cyber threats faced by the library continues to increase, its chief information officer, Manlio Miceli, tells the Observer. Threats to digital security come in many shapes and sizes, but Miceli notes that criminals can tamper with the librarys digitized files or conduct a ransomware attack, in which hackers effectively hold files ransom in exchange for a hefty sum.
While physical damage is often clear and immediate, an attack of this kind wouldnt have the same physical visibility, and so has the potential to cause enduring and potentially irreparable harm, not only to the archive but to the worlds historical memory, Miceli tells the Observer.
He adds, These attacks have the potential to impact the Vatican librarys reputationone it has maintained for hundreds of yearsand have significant financial ramifications that could impact our ability to digitize the remaining manuscripts.
Though the Vatican Library dates back to the days of the first Roman Catholic popes, little is known about the contents of its collections prior to the 13th century, per Encyclopedia Britannica. Pope Nicholas V (14471455) greatly expanded the collection, and by 1481, the archive held the most books of any institution in the Western world, according to the Library of Congress.
To date, about a quarter of the librarys 80,000 manuscripts have been digitized. As Kabir Jhala reports for the Art Newspaper, holdings include such treasures as Sandro Botticellis 15th-century illustrations of the Divine Comedy and the Codex Vaticanus, one of the earliest known copies of the Bible. Other collection highlights include notes and sketches by Michelangelo and the writings of Galileo.
The Vatican debuted the digitized version of its prized Vergilius Vaticanus in 2016. One of the few remaining illustrated manuscripts of classic literature, the fragmented text features Virgils Aeneid, an epic poem detailing the travels of a Trojan named Aeneas and the foundation of Rome. The ancient documentlikely crafted around 400 A.D. by a single master scribe and three paintersstill bears its vivid original illustrations and gilded lettering.
The library isnt the only section of the Vatican thats prone to cyber breaches. As the New York Times reported in July, Chinese hackers infiltrated the Holy Sees computer networks this summer ahead of sensitive talks in Beijing over the appointment of bishopspart of ongoing discussions that will determine how the Catholic Church operates in China.
The only way to make an organization completely secure is to cut it off from the internet, Miceli tells the Observer. Our mission is to bring the Vatican Library into the 21st centuryso we wont be doing that any time soon.
