How you walk is special–and is as good at identifying us as our fingerprints. Footstep recognition systems could replace other biometrics for security and identity confirmation, letting us keep walking instead of queuing and waiting at airports.
That’s according to Omar Costilla-Reyes, a researcher at the University of Manchester. He has built a floor sensor system and paired it with a neural network algorithm to identify people by their footsteps, which have 24 different characteristics. And it works, with an encouraging 0.7 error rate per hundred people. Here, he reveals how the system works.
Gait analysis isn’t new. What have you done differently here?
This is not something we’ve created, but what we did differently is footstep analysis [rather than gait]. That means we only need two footsteps to recognise…
