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.'"

Electrical properties of living creatures are not really known for being stable, particularly among sick people, the intended users for this device. Good thing that the summary has so little to do with the paper, because the summary is pretty silly
