Researchers from the Carnegie Mellon University's Biometrics Research and Identity Automation Lab are developing new ways to enable security based on body's movements, which, unlike retinal scans and fingerprints, can't be taken from an individual, the New York Daily News reported.
The new discipline called "pedo-biometrics" uses a "BioSole" inserted into shoes to assess a wearer's gait, matching that distinctive pattern against an existing record to verify the person's identity.
Biometrics have a decided advantage over passwords because they don't rely on users' ability to remember them, the system identifies users based on something they are, for example with a retina or fingerprint scan.
Most authentication systems need "things you know", but more advanced systems need "things you are", explained NBC News.
Fingerprints and retina scans fall into the latter category but can still be penetrated - by amputating the corresponding body part.
The university is teaming up with Autonomous ID, a company based in Ottawa, Canada, to create passwords based on behavioural validation.
