Researchers Use Bioimpedance As A Biometric, Let Health Monitor Devices Know Who You Are

By Staff Author | August 13, 2012

Researchers use bioimpedance as a biometric, let health monitor devices know who you areWouldn’t it be great if fitness and medical gadgets automatically knew who was wearing them? Researchers from Dartmouth have come up with a new way to provide health monitors just such an ability using a tiny electric current and a bioimpedance sensor. You see, each person’s body provides a different amount of opposition to electrical current, so bioimpedance can be a unique biometric identifier. The researchers’ idea is to create a bracelet that uses bioimpedance readings to recognize its wearer in a secure, unobtrusive manner and communicate that identity to other wearable devices.

Using such a bracelet, “the devices discover each other’s presence, recognize that they are on the same body (and transitively learn from the wrist device whose body), develop shared secrets from which to derive encryption keys, and establish reliable and secure communications.” As opposed to other biometrics or password authentication, bioimpedance readings can be taken passively, which is much more appealing than remembering passcodes or scanning fingerprints and retinas. For now, the researchers have created an eight-electrode proof-of-concept bracelet, but its accuracy leaves something to be desired — it correctly identifies its wearer only 80 to 90 percent of the time, whereas fingerprint recognition has a failure rate of less than 1 in 1,000. So, we’re a ways off from bioimpedance-based security, but research is ongoing, and you can learn all about it at the source below.
