Microsoft, Google Use Artificial Intelligence to Fight Hackers

Posted by in categories: information science, robotics/AI, security

Last year, Microsoft Corp.’s Azure security team detected suspicious activity in the cloud computing usage of a large retailer: One of the company’s administrators, who usually logs on from New York, was trying to gain entry from Romania. And no, the admin wasn’t on vacation. A hacker had broken in.

Microsoft quickly alerted its customer, and the attack was foiled before the intruder got too far.

Chalk one up to a new generation of artificially intelligent software that adapts to hackers’ constantly evolving tactics. Microsoft, Alphabet Inc.’s Google, Amazon.com Inc. and various startups are moving away from solely using older “rules-based” technology designed to respond to specific kinds of intrusion and deploying machine-learning algorithms that crunch massive amounts of data on logins, behavior and previous attacks to ferret out and stop hackers.

​Filipino IT experts hope NASA announces Space Challenge winners as U.S. government operations resume

Posted by in categories: government, law, security, space

This is the first time that an entry from the Philippines has made it to the global finalists. http://verafiles.org/articles/filipino-it-experts-hope-nasa-…lenge-winn #SpaceApps #SpaceAppsPH


Filipino Information Technology enthusiasts are hoping that the temporary reopening of U.S. government operations after a 35-day shutdown would pave the way for the announcement of the winners in the NASA Space Apps Challenge, where one of the finalists is an app developed by a group of Filipino IT experts.

The announcement of the winners in the global competition was supposed to have been made in mid-January but has suffered a delay due to the federal government shutdown caused by a standoff over border security.

AI Created in DNA-Based Artificial Neural Networks

Posted by in categories: bioengineering, biotech/medical, mathematics, neuroscience, robotics/AI, security

Mention artificial intelligence (AI) or artificial neural networks, and images of computers may come to mind. AI-based pattern recognition has a wide variety of real-world uses, such as medical diagnostics, navigation systems, voice-based authentication, image classification, handwriting recognition, speech programs, and text-based processing. However, artificial intelligence is not limited to digital technology and is merging with the realm of biology—synthetic biology and genomics, to be more precise. Pioneering researchers led by Dr. Lulu Qian at the California Institute of Technology (Caltech) have created synthetic biochemical circuits that are able to perform information processing at the molecular level–an artificial neural network consisting of DNA instead of computer hardware and software.

Artificial intelligence is in the early stages of a renaissance period—a rebirth that is largely due to advances in deep learning techniques with artificial neural networks that have contributed to improvements in pattern recognition. Specifically, the resurgence is largely due to a mathematical tool that calculates derivatives called backpropagation (backward propagation)—it enables artificial neural networks to adjust hidden layers of neurons when there are outlier outcomes for more precise results.

Artificial neural networks (ANN) are a type of machine learning method with concepts borrowed from neuroscience. The structure and function of the nervous system and brain were inspiration for artificial neural networks. Instead of biological neurons, ANNs have artificial nodes. Instead of synapses, ANNs have connections that are able to transmit signals between nodes. Like neurons, the nodes of ANNs are able to receive and process data, as well as activate other nodes connected to it.

Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

Will humanity survive this century? Sir Martin Rees predicts ‘a bumpy ride’ ahead

Posted by in categories: biotech/medical, governance, security

Humanity is under threat. At least according to Sir Martin Rees, one of Britain’s most esteemed astronomers.


These two kinds of technologies enable just a few people to have a hugely wide-ranging and maybe even global cascading effect. This leads to big problems of governance because you’d like to regulate the use of these things, but enforcing regulations worldwide is very, very difficult. Think how hopeless it is to enforce the drug laws globally or the tax laws globally. To actually ensure that no one misuses these new technologies is just as difficult. I worry that we are going to have to minimize this risk by actions which lead to a great tension between privacy, liberty and security.

Do you see ways that we can use and develop these technologies in a responsible way?

Generating Actionable Understanding of Real-World Phenomena with AI

Posted by in categories: robotics/AI, security

Rapid comprehension of world events is critical to informing national security efforts. These noteworthy changes in the natural world or human society can create significant impact on their own, or may form part of a causal chain that produces broader impact. Many events are not simple occurrences but complex phenomena composed of a web of numerous subsidiary elements – from actors to timelines. The growing volume of unstructured, multimedia information available, however, hampers uncovering and understanding these events and their underlying elements.

“The process of uncovering relevant connections across mountains of information and the static elements that they underlie requires temporal information and event patterns, which can be difficult to capture at scale with currently available tools and systems,” said Dr. Boyan Onyshkevych, a program manager in DARPA’s Information Innovation Office (I2O).

The use of schemas to help draw correlations across information isn’t a new concept. First defined by cognitive scientist Jean Piaget in 1923, schemas are units of knowledge that humans reference to make sense of events by organizing them into commonly occurring narrative structures. For example, a trip to the grocery store typically involves a purchase transaction schema, which is defined by a set of actions (payment), roles (buyer, seller), and temporal constraints (items are scanned and then payment is exchanged).

Our Cellphones Aren’t Safe

Posted by in category: security

The international mobile communications system is built on top of several layers of technology, parts of which are more than 40 years old. Some of these old technologies are insecure, others have never had a proper audit and many simply haven’t received the attention needed to secure them properly. The protocols that form the underpinnings of the mobile system weren’t built with security in mind.


Security flaws threaten our privacy and bank accounts. So why aren’t we fixing them?
