Researchers have developed an artificial 'nose' that can identify individuals from their breath. Built with a 16-channel sensor array that can detect different compounds found in a person's breath, the olfactory sensor system has the potential to become another option in the biometric security toolkit. Combined with machine learning, the 'artificial nose' was able to authenticate up to 20 individuals with an average accuracy of more than 97%.

In a project aimed at developing intelligent tools to fight child exploitation, computer scientists have developed a system to analyze the noise produced by individual cameras. This information can be used to link a video or an image to a particular camera.

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 trick.

A team of engineers has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals' movements.

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 are building a suite of new insights into crime scene investigation -- including the difference between high, intermediate and low skin 'shedders' that will help understanding of trace or 'touch DNA'.

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 subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel.

A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.

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 methods.

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: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.

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, tumors that are more solid may be relatively stable, whereas more fluid-like growths could be more prone to mutate and metastasize.

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 data in healthcare and biomedical research?

A novel chip automates the reaction cascades occurring between molecules inside DNA to carry out complex mathematical calculations.

The Glasgow Face Matching Test has been updated to find super-recognizers who can help prevent errors caused by face recognition software.

Engineers have developed an integrated circuit that can carry out complicated artificial-intelligence operations like face, voice and gesture recognition and cardiac monitoring. Powered by either a tiny battery or a solar panel, it processes data at the edge and can be configured for use in just about any type of application.

Researchers have developed a plasmofluidic chip that can perform PCR in only about 8 minutes, which could speed diagnosis during current and future pandemics.

Researchers have moved closer toward this goal by developing a nanopore sequencing platform that, for the first time, can detect the presence of nucleobases, the building blocks of DNA and RNA.

New research shows 3D printers can be identified by thermodynamic properties, which could could aid intellectual property, security.

Careful criminals usually clean a scene, wiping away visible blood and fingerprints. However, prints made with trace amounts of blood, invisible to the naked eye, could remain. Dyes can detect these hidden prints, but the dyes don't work well on certain surfaces. Now, researchers have developed a fluorescent polymer that binds to blood in a fingerprint -- without damaging any DNA also on the surface -- to create high-contrast images.

Since the introduction of plastic (polymer) banknotes in 2016, the number of counterfeit notes on the streets has increased, however, researchers have developed a novel technique called Polymer Substrate Fingerprinting, which identifies every banknote's fingerprint which is unique and unclonable.

The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target.
