Pedo-Biometrics Lab (Carnegie Mellon University, Pittsburgh) is working on high-tech shoe insoles designed to monitor access to high-security areas such as military bases or nuclear power plants. The concept for these insoles builds on extensive research that shows individuals have unique feet and ways of walking.
Sensors in the biometric soles check the pressure of feet and monitor gait. Its microcomputer compares these patterns with a master file for that person. By the third step, it can determine the match or not. If not, a wireless alarm triggers a message. The sensor also detects when someone is wearing another person’s shoes.
Scientists have known for centuries that each person has a unique way of walking. The U.S. Department of Defense and the Chinese government pour millions into funding gait research. The Institute of Intelligent Machines is also doing extensive research into gait biometrics. There are even reports of floors designed to monitor footsteps without people being aware of it.
