Computer scientists design way to close 'backdoors' in AI-based security systems

It sounds like a plot out of a spy novel, with a touch of cyberpunk: An agent approaches a secure location, protected by a facial recognition system, accessible only to a head of state or CEO. Flashing an unusually shaped earring, the agent tricks the system into thinking they're that VIP, opening the door and exposing the secrets inside. The key—an undetectable "sleeper cell" was placed inside the AI behind the security system months or years earlier to grant access to anyone wearing the specified jewelry.

Researchers develop secure method for sending sensitive personal data from wearable tech

Smart watches. Pacemakers. Internet-connected glasses. These are devices designed to make life easier. And yet, all this wearable technology can be hacked. The devices send personal health information to your smartphone over the airways, so anyone with the know-how could scoop it up and steal it. But now, researchers at Northeastern have a better, more secure idea: Send data through your body.

A simple technique allows robots to recognize touch and proximity

Researchers at the University of Hertfordshire have recently proposed an easy and configurable technique that enhances a robot's ability to perceive and interact with people in its surroundings. Their technique, presented in a paper pre-published on arXiv, utilizes affordable Bluetooth low energy (BLE) devices. Among its many possible applications, it could enhance therapy for children with autism spectrum disorder (ASD), allowing robots to act as mediators and monitor children in their surroundings.

Using a printed adversarial patch to fool an AI system

A trio of researchers at the University of KU Leuven in Belgium has found that it is possible to confuse an AI system by printing a certain picture and holding it against their body as the AI system tries to identify them as a human being. Simen Thys, Wiebe Van Ranst and Toon Goedemé have written a paper describing their efforts and have uploaded it to the arXiv preprint server. They have also posted a video on YouTube showing what they accomplished.

DNA folds into a smart nanocapsule for drug delivery

Researchers from University of Jyväskylä and Aalto University in Finland have developed a customized DNA nanostructure that can perform a predefined task in human body-like conditions. To do so, the team built a capsule-like carrier that opens and closes according to the pH level of the surrounding solution. The nanocapsule can be loaded—or packed—with a variety of cargo, closed for delivery and opened again through a subtle pH increase.
