The three letter agencies (and Walmart, and anyone who can pay for it) have gait analysis that IDs you by how you walk, no face needed

That's why you put a pebble in your shoe. Then after enough years you take it out like Piccolo dropping his weighted clothes and, like Harrison Bergeron in the story, defy the authoritarian state with dance.

Why do we get all the bad stuff from Little Brother, but not the free Xboxes???

  Because Cory Doctorow is paying attention!

Counter-surveillance techniques for gait analysis are already well understood. https://www.youtube.com/watch?v=TNeeovY4qNU https://www.youtube.com/watch?v=TNeeovY4qNU

  If you walk without rhythm you won't attract the worm?

No. Gait analysis is not really a commercialized thing.

    That is not gait detection, it's basic object detection video analytics.

  Granted vr telemetry is based off of multiple cameras tracking a single individual - still, one wonders how hard it would be to cover a crowd with specific aim of identification and tracking? https://www.theregister.com/2023/02/18/vr_telemetry_identity/ https://www.theregister.com/2023/02/18/vr_telemetry_identity...

    For all practical purposes, it is impossible in the current state of security/surveillance video footage. The example described in the paper in your link is using cameras that are setup to provide very high resolution images of people. It would be like using full-frame portrait images for face recognition, and then expecting that to translate to real-world scenarios where you might only have 20 pixels on a face, and the person is off-axis to the camera. Gait detection has been discussed for a while, and may definitely be a thing one day, but right now we are barely at the point where pose estimation is a thing in security video. Very far from being able to do high precision pose recognition and sampling over successive frames to model something that would qualify as "gait".
