(Phys.org)—What about using the same mobile device touchscreens used every day for direct authentication? What if your touch alone identifies you by code from the ring on your finger? A team from the WINLAB at Rutgers University has turned the what-ifs into a device that makes use of capacitive touchscreens on phones and tablets to confirm the user's identity. The device can provide an additional layer of protection alongside passwords. The device can send a few bits of data representing a password from a special battery powered ring (with flash memory) on the finger. The data is sent as tiny voltage bursts through the wearer's skin for phone-screen capture.
