Yahoo researchers turn phone touchscreens into biometric sensors

Called Bodyprint, the technology uses the touchscreen as an imaging sensor in order to detect not just fingers but also knuckles, palms, and even ears. These can then be used to identify and authenticate a user, or even multiple users each with their own unique finger, palm, or ear prints.

Aside from potentially becoming more available to any device that has a touchscreen, Bodyprint also extends the authentication beyond a single person use case. Two people can, for example, lock and sign a document and only when those two have given their bodyprint.

That said, Bodyprint is still in the research stage and there's no indication yet whether anyone, even Yahoo, plans to take this further. As for accuracy, the team tested the system on 12 subjects and they got very impressive results, identifying body parts with 99.98 percent accuracy and identifying users 99.52 percent accuracy, with low false positives of 26.82 percent.

I feel nervous with biometric phone screens and the NSA existing in the same universe.
