Soundbite: watching how we walk

Posted on: July 9, 2011

It turns out that the particular way we all walk–the cadence of our footsteps, the way we swing our arms and legs and so on–is about as individual as a fingerprint, and basically needs just enough seconds of video feed of someone walking to compare to a database.

The benefits of gait spotting include working from more angles, as people can’t be relied upon to stare at cameras for face recognition, and that it can work in the rain–when coats and umbrellas also obscure people’s faces
