As we all know, we can be identified by nearly anything. There is face recognition, voice recognition, fingerprints, DNA, all sorts of biometrics and now they want to add footprints as well. Footprints are as good as fingerprints for identification but it is not only that. The way bare foot hits and leaves the ground while walking creates foot-pressure patterns and those patterns can be used to reveal your identity. Scientists now try to find ways to extract patterns from people walking with shoes.
