Gait biometric systems capture step patterns using video images and then convert the collated data into a mathematical equation. Gait as a biometric measure can be influenced by several factors, including footwear, terrain, fatigue, and injury.
…Love this sub, I don’t have hardcore needs in terms of privacy, but wanted to know for people that enjoy a covid mask, their opinion on Gait Rec. Technologies, and does any one have any intel in throwing these systems off, whether or not that is impossible?
Depends on the tech, but essentially you need to adjust stride length, foot pronation/supination, knee extension and a bunch of things about hip alignment.
Someone walking while looking at their phone will ID differently than the same person walking fast while trying not to run.
BUT, in the same context with the same footwear, these systems are pretty accurate. So in places with CCTV, they can be pretty quick at tagging and filtering regular repeated activity. That way, it’s the unrecognized gaits that get flagged up for investigation.
Thanks for the reply, makes a lot of sense.
