June 8, 2022 Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the ...
Mar. 31, 2022 Skin cells and their DNA varies between individuals, but new data shows that some groups of people have higher variability in their cell deposits. The South Australian forensic science researchers ...
Mar. 18, 2022 Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of ...
Dec. 10, 2021 A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential ...
Nov. 15, 2021 Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic ...
Nov. 4, 2021 To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: ...
Oct. 25, 2021 Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, ...
Oct. 14, 2021 Uses of facial images and facial recognition technologies -- to unlock a phone or in airport security -- are becoming increasingly common in everyday life. But how do people feel about using such ...
