Yahoo has announced a new biometric authentication solution based on the recognition of distinct parts of the body, with no hardware needed for enrolment except a capacitive touchscreen.
During the 2015 Computer-Human Interaction Conference (CHI) in Seoul, Yahoo researchers demonstrated the solution called Bodyprint.
Bodyprint can scan users’ ears, knuckles, palms and fingers when they are pressed against the touchscreen. Sensors in the screen map the topography of these body parts, which are unique to each individual.
Since all current touchscreens use capacitive sensing, Bodyprint brings reliable biometric authentication to a vast number of commodity devices.
A pilot of 12 participants showed an accuracy of 99.52%. The research has been led by Christian Holz, a researcher in Human-Computer Interaction at Yahoo Labs, along with Senaka Buthpitiya, and Marius Knaust.
