article_snippet.sent: Called Bodyprint, the technology turns a standard touchscreen into a biometric scanner removing the need to specialist hardware such as fingerprint readers or infrared cameras.
article_snippet.sent: Details of Bodyprint algorithm are included in their paper, Bodyprint: Biometric User Identification on Mobile Devices Using the Capacitive Touchscreen to Scan Body Parts.
article_snippet.sent: Recent mobile phones integrate fingerprint scanners to authenticate users biometrically and replace passwords, making authentication more convenient for users,' explained the researchers. '
article_snippet.sent: However, due to the researchers cost, capacitive fingerprint scanners have been limited to top-of-the-line phones, a result of the required resolution and quality of the sensor.'
article_snippet.sent: capacitive fingerprint scanners continued that while the input resolution of a touchscreen is around six dots per inch (dpi) - meaning a touchscreen can't capture the level of detail in a fingerprint - the surface area is larger than a more advanced reader.
article_snippet.sent: This allows the touch sensor 'to scan users’ body parts, such as ears, fingers, fists, and palms by pressing capacitive fingerprint scanners against the display.'
article_snippet.sent: A video demonstrating the technology revealed Bioprint can also be used to add multiple users to a single device.
