Sensor Uses Body's Electrical Signature To Secure Devices


coondoggie writes with word that a "group of researchers is proposing a sensor that would authenticate mobile and wearable computer systems by using the unique electrical properties of a person's body to recognize their identity. In a paper [presented Monday] at the USENIX Workshop on Health Security and Privacy, researchers from Dartmouth University Institute for Security, Technology, and Society defined this security sensor device, known as Amulet, as a 'piece of jewelry, not unlike a watch, that would contain small electrodes to measure bioimpedance — a measure of how the body's tissues oppose a tiny applied alternating current- and learns how a person's body uniquely responds to alternating current of different frequencies.'"
