A suspect says it on every forensics TV show ... "Of course my
fingerprints were at their house, I delivered a package to them earlier
this week!" Soon, though, that excuse may not be enough. Using a new
technique, investigators could be better able to determine how many days
ago fingerprints were left at a crime scene.
Attempts to move beyond password authentication look to have just received a nice little boost, with interface-specialists Synaptics announcing its new Match-in-Sensor, billed as the first self-contained fingerprint matching device. The solution promises new degrees of security by isolating the entire process from a host device like your phone or computer, minimizing the chances of somebody else getting their fingers on your prints.
Researchers at the University of California, Davis and Berkeley have managed to miniaturize low-depth ultrasound technology to create a fingerprint sensor that can scan your finger in 3D. This low-power technology, which could improve on the robustness of current-generation capacitive scanners, could soon find its way to our smartphones and tablets.
A team led by researchers at the University of Surrey in the United Kingdom has developed a new, non-invasive test that's able to detect cocaine use in a patient by analyzing a single fingerprint. Unlike existing tests, the new technique is able to determine whether the subject has ingested the drug, rather than just touched it.
