Yahoo! introduced a new technology that allows smartphones to unlock parts of the body. With name Bodyprint (or body printing, in free translation), the biometric authentication system uses the capacitive touchscreen as a scanner, mapping the topography ears, wrist, phalanx, palms and fingers.

The method works because the relief of these parts of the body is unique to each individual, according to the study of Yahoo . “To accept an incoming call, the user places the screen in her ear. Bodyprint extracts the characteristics of raw capacitive image to identify the user, “says the study, led by Christian Holz, researcher in Human-Computer Interaction in Yahoo Labs.
The experiment was attended 12 people and achieved 99.52% accuracy. The technology would be used in mobile devices commodity, namely, basic devices produced for various manufacturers. So far, biometric authentication is restricted to high-end smartphones and requires proprietary hardware for this purpose.
