A new twist in multi-factor authentication..Bio-Soles!

The concept is based on research that shows each person has unique feet, and ways of walking. Sensors in the bio-soles check the pressure of feet, monitor gait, and use a microcomputer to compare the patterns to a master file for that person. If the patterns match the bio-soles go to sleep. If they don't, a wireless alarm message can go out.

A good thing my company doesn't use these. I twisted my ankle last week and would still be setting off alarms...

Still, interesting concept. Up there with the Inner Ear Biometrics (pdf here) or the "Butt Biometrics".

Interesting, yes. Practical? Hmmm
