Neural networks can find telltale patterns in a person’s gait that can be used to recognize and identify them with almost perfect accuracy, according to new research published in IEEE Transactions on Pattern Analysis and Machine Intelligence. The new system, called SfootBD, is nearly 380 times more accurate than previous methods, and it doesn’t require a person to go barefoot in order to work. It’s less invasive than other behavioral biometric verification systems, such as retinal scanners or fingerprinting, but its passive nature could make it a bigger privacy concern, since it could be used covertly.

To test the SfootBD system, Reyes’ team monitored participants in three different scenarios: [...]
Results showed that, on average, the system was 100 percent accurate in identifying individuals, with an error rate of just 0.7 percent.

This new system does have some limitations. As noted, SfootBD requires the use of floor pads and a high-res camera, so this form of surveillance and identification can’t be used just anywhere. [...] the only individuals who can be identified are those whose distinctive gaits have been previously recorded and cataloged in the system. Finally, there are also issues of privacy and consent to consider, as this technology could be used surreptitiously.

Tracking people by their 'gait signature' seems to have been around a while

If they can see me walking, I'm not expecting much privacy
