Turning a Smartphone Display Into a Biometric Scanner 16
New submitter jan_jes writes: Recent mobile phones integrate fingerprint scanners to authenticate users biometrically and replace passwords, making authentication more convenient. Researchers at Yahoo Labs have created a new technology called "Bodyprint," which turns your smartphone's touchscreen display into a biometric scanner. It allows the touch sensor to scan users' body parts (PDF) such as ears, fingers, fists, and palms by pressing them against the display. Bodyprint implements the four-eye principle for locking sensitive documents — accessing the document can require the presence of two or more people involved with the project. Another application is authenticating a user to answer a call by scanning their ear pressed against the phone.
