Face recognitions and hand mapping seems to have become old methods of acting as ID checkups. Pedo-Biometrics Lab at Carnegie Mellon University has been working since 2009 to create the biometric sole, which will act as new ID checker.

The lab has partnered with Autonomous ID, a Canadian company, and has received $US1.5 million in the form of funding. Marios Savvidesm, who is the head of the lab, was of the view that they decided to track feet as everyone has different feet and they also differ in their walk.

Sensors, which when will be fitted in shoes soles, will be able to assess the pressure on feet and movement of the feet. A file then will be prepared of people and will be used at the time of entry. If the sole gets matched then the alarm will go to sleep mode and if not then it will raise an alarm.

Todd Gray, who has partnered with the lab and owner of Autonomous ID, was of the view that they wish to develop a cost effective ID system, which can be used in high-security areas.

"Any biometric capture device is a potential tracking device, just like every iPhone is a potential tracking device. That's just the way these things are”, said Lee Tien, who is positioned as an attorney with the Electronic Frontier Foundation.
