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?

      haha curious if this would work although in that article i linked to :

      “Your gait is like a fingerprint, unique and impossible to falsify.”

        I’m sure the companies selling the software want people to think that. Automatic Fingerprint ID has enough false positives, I can’t imagine this wouldn’t be worse.

    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.

      This and the initial article are central plot points in Cory Doctorow’s Little Brother.

      It’s a YA novel about a guy who helps organize resistance against the government by hacking Xboxes. There are at least 2 sex scenes. The ending is deeply unsatisfying, perhaps because the author wanted to convey that he alone cannot possibly succeed
