Researchers at Pittsburgh’s Carnegie Mellon University have a new high-tech security device that puts eye scans to shame. The lab is working on the biometric shoe. They have developed special shoe insoles help high security spaces, such as military bases, nuclear powers plants, etc., monitor access to areas.

According to research, every person has a different way of walking and standing. The biometric sole has sensors that measure the pressure of feet when standing and stepping. The information is put on a microcomputer in the sole with the patterns collected. The information is then compared to the master file to determine the person’s identity. If the match is positive, then the soles go to sleep. If it is determined that they don’t match, a wireless alarm message will send a message regarding the security breach.

“It’s part of a shoe that you don’t have to think about,” said Marios Savvides, head of Carnegie Mellon University’s new Pedo-Biometrics Lab, in Pittsburgh. While researchers have noted that gait can vary with injuries, fatigue and other factors, Savvides said the bio-soles can detect signs of those things, too.

The lab is in a partnership with Canadian company, Autonomous ID. Todd Gray, the company’s president, came up with the idea after the birth of his daughter. While at the maternity ward, Gray noticed the footprints of the different babies on the wall. Soon after, the company began developing prototypes with the goal of creating a sole no thicker than regular soles sold at local drug stores and have an accuracy rate of more than 99 percent.

According to Gray, The Pedo-Biometrics Lab is expanding the testing to “a full spectrum of society: big, tall, thin, heavy, athletic, multicultural, on a diet, twins and so on.”

The idea may seem to futuristic but, the U.S. Department of Defense has already funded millions into research and The Institute of Intelligent Machines has been not only researching gait biometrics but, also floors that can monitor people’s footsteps without them knowing.
