Wearable electronics have been gaining in popularity recently, with security and privacy issues following close behind. New technologies might provide a solution to the security challenges associated with these gadgets – devices that can scan users and verify their identity.

A new device of this type was recently unveiled by researchers from Dartmouth College. According to MIT Technology Review the device includes four pairs of electrodes worn around the wrist like a bracelet. Researchers discovered that the resistance measured between the electrodes is biometric: Unique to every individual, based on their body composition, bone size and flesh thickness.

After the device measures the resistance a wireless ID signal is sent, confirming the wearer’s identity for other electronic devices. The developer of the new technology, Corey Cornelius, explained: “If I’m wearing the bracelet, my phone would be unlocked without a PIN code, or I could log into my PC or provide a means of access control.” Cornelius added that the device is very precise, but over the long run calibrations will be needed to compensate for aging, disease, losing or gaining weight, etc.
