I disagree... this is an area I research, working on a surveillance system. But even so, if gait alone was not enough, modern recognition software can easily single out a subject in a crowd with just seconds of footage, and through thousands of cameras track said subject throughout the city. Footage will be plenty. At some point during tracking the subject is likely to reveal his face, too, or other critical information. If your voice is picked up it too will be used for positive identification. When you add in the people in close proximity to the subject things get even easier, recognize one of the other collaborators the target subject affiliates with and identification is often a simple narrowing scan of enmassed OSINT away, done real-time, of course. Or simply track the subject to an address, maybe even his home, and swoop in.
I want to also clarify what gait recognition is, for those not that familiar with it a common misconception is thinking it is limited to analysis of how you walk. It is not; factors of gait recognition: height, weight, build and proportions, sex, age, clothes (including type—-dress, shirt, etc.—-shape and colors), emotions displayed, facial tics, unique mannerisms. The analysis of your actual walk/gait is incredibly deep and consists of hundreds of variables, too many for me to care mention here, I might blog about it if it is of interest to anyone, but a few examples: cadence, the angles of just about anything you can imagine possible to measure,
spacing between feet, knees, arm swing distance, etc.
For anyone familiar with Haar-like features it should be easy enough to understand that with enough features within threshold you can id just about
anything.
This is all yesterday’s tech, by the way.
My point, be very cautious of attending anything that might destroy your
future. Do not think a mask or blurring protects your identity, that is extremely naive.

If you're afraid to be seen in public you have no future to destroy. It has always been possible to identify people with diligence if one is sufficiently patient. Given that you're 'working on a surveillance system' your post reads as little more than an attempt to intimidate people from participating in political activism.
I am talking about participating in unlawful activities. I do not think most people need to be afraid of being seen in public.
The system I am working on is not for law enforcement.
I respect people standing up for what they believe in. I do not respect people destroying the property of others.
I see no harm in «educating» people. Even on HN I think there is few who understands fully modern surveillance capabilities. Knowledge is power, I believe information wants to be free.
No, you talked about attendance of an event - I quoted you in order to make the context clear. It is simply untrue to say you were talking about participating in unlawful activities.
