Fingerprint authentication systems are a widely trusted, ubiquitous form of biometric authentication, deployed on billions of smartphones and other devices worldwide. Yet a new study reveals a surprising level of vulnerability in these systems. Using a neural network trained to synthesize human fingerprints, the research team evolved a fake fingerprint that could potentially fool a touch-based authentication system for up to one in five people.
Scientists from ITMO University have proposed a new technology for creating optical micro-waveguides using inkjet printing. Using this method it is possible to quickly create waveguides with the necessary parameters without expensive equipment and complex procedures. The new technology is optimized for the production of optical elements on an industrial scale. The results are published in Advanced Optical Materials ?n 20th November 2018.
Researchers from Duke University demonstrate a new optical waveguide capable of bending photons around tight corners on a smaller scale than previously possible. The technology is made possible by through photonic crystals using the concept of topological insulators.
A pair of electrical engineering and computer science professors in Cleveland, Ohio, have been experimenting with a new suite of smart-home sensors. Their system would read not only the vibrations, sounds -- and even the specific gait, or other movements -- associated with people and animals in a building, but also any subtle changes in the existing ambient electrical field. The presented their findings at a conference in New Dehli, India, in October.
Virginia Tech researchers found a way to give high-performance computing data systems the flexibility to thrive with a first-of-its-kind framework called BespoKV, perhaps helping to one day achieve the HPC goal of performing at the exascale, or a billion billion calculations per second.
Scientists at the University of Sussex have developed a piece of hardware to demonstrate how our brains function, as part of a growing range of equipment which uses DIY and 3D printable models to open up access to science education.
Researchers at the University of Waterloo have taken a huge step towards making smart devices that do not use batteries or require charging.
Web browsers use GPUs to render graphics on desktops, laptops, and smart phones. GPUs are also used to accelerate applications on the cloud and data centers. GPUs are usually programmed using application programming interfaces, or APIs, such as OpenGL. OpenGL is accessible by any application on a desktop with user-level privileges. Since desktop or laptop machines by default come with the graphics libraries and drivers installed, the attack can be implemented easily using graphics APIs.
Scientists in Australia have for the first time demonstrated the protection of correlated states between paired photons using the intriguing physical concept of topology. This experimental breakthrough opens a pathway to build a new type of quantum bit, the building blocks for quantum computers.
Like a 'needle in a haystack,' human auditors have the painstaking task of manually checking thousands of Medicare claims for specific patterns that could indicate foul play or fraudulent behaviors. Currently, fraud enforcement efforts rely heavily on health care professionals coming forward with information about Medicare fraud. Researchers are the first to use big data from Medicare Part B and employ advanced data analytics and machine learning to automate the fraud detection process.
