Un sensor per llegir la signatura elèctrica del cos i utilitzar-lo per identificar el propietari d'un gadget
Presentada a la conferència USENIX Workshop on Health Security and Privacy una tècnica que podria permetre als gadgets identificar el seu legítim propietari a partir de la detecció de les propietats elèctriques úniques del seu cos:
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." The device uses a recognition algorithm to determine whether the person matches the measured bioimpedance.
Once identity has been established a person would be able to simply attach other devices to their body — whether clipped on, strapped on, stuck on, slipped into a pocket, or even implanted or ingested — and have the devices just work. That is, without any other action on the part of the user, the devices discover each other's presence, recognize that they are on the same body, develop shared secrets from which to derive encryption keys, and establish reliable and secure communications, the researchers stated.
