Chinese Police Test Gait-Recognition Technology That Identifies People Based on How They Walk (scmp.com)

You can tell a lot of things from the way someone walks. Chinese artificial intelligence start-up Watrix says its softwares can identify a person from 50 meters away -- even if they have covered their face or have their back to a camera -- making it more than a match for Sherlock Holmes. From a report: Known as gait recognition, the technology works by analyzing thousands of metrics about a person's walk, from body contour to the angle of arm movement to whether a person has a toe-in or toe-out gait, to then build a database. "With facial recognition people need to look into a camera -- cooperation is not needed for them to be recognized [by our technology]," said Huang Yongzhen, co-founder and chief executive of Watrix, in an interview in Beijing. Features like this have given Watrix an edge in catching runaway criminals, who tend to avoid surveillance, said Huang. Police on the streets of Beijing, Shanghai and Chongqing, have already run trials of gait recognition technology, said Huang, and the company officially launched its 2.0 version last week, which supports analysis of real-time camera feeds at a mega-city level.

Keep in mind, I had only met this cousin once in my entire life, when I was a young child. He's 40 years older, we didn't share an obvious name (doubly-maternal side relationship for me, so he didn't even share my mom's maiden name), and the last time I would have met him, he was living 1000 miles away from where she ran into him.

      Putting a rock in your shoe is more like using crutches to walk, an "assistive" (in a loose sense) device that changes your gait pattern by modifying the needed locomotion kinematics for motion by changing your loading patterns. Crutches or a walker would help, a rock would obviously hinder but result in a change none the less. You could also use straps, bands, tape on various muscle groups to change your gait under your pant leg. Some people actually put tape on cats and dogs to demonstrate this (plenty of videos on YouTube) but usually not for productive purposes like is used in physical therapy.

      The comparison you described is more akin to removing the crutches (assistive device) before a patients leg heals. The assistive device is critical in creating a different yet repeatable pattern of locomotion which is why recovery uses such techniques, so you can alter your gait pattern (most likely in hindering way) by using similar assistive techniques.

      As various remote sensing technologies improve, reduce in cost and become more pervasive coupled with improvements in pattern recognition techniques, I supect public disguise will become nearly pretty much impossible. Regulating this stuff and enforcing regulations with hefty penalties will be the only real solution for public privacy.

      As many popular dystopian works people have been exposed to, I'm surprised more people aren't up in arms to prevent private entities from doing the same in the US.

      Assuming steady computational power growth and improvements in low cost sensor technologies, it's pretty much inevitable that tracking in public will be commom state of affairs. Our culture tends to work on a reactionary basis instead of laying groundwork of prevention so I find it worrying that this will occur in the US.

      In a metropolitan or suburban area, a private entity could relatively easily deploy sensors that cover most of a region. They could then collect all the data privately, creating their own tracking system. They could then easily sell/license this information which local police, government officials, etc. who could use this information without a search warrant needed. It's really no different than what Equifax does when you think about it.

      The more and more privatized our country becomes, the less protections we can be afforded for privacy and basic rights. Imagine a future where most property is owned by a few wealthy individuals (we're not far away already). There will be little constitutional restrictions to what private capital can do on their own property with respect to surveillance, just like what Equifax can do with accumulating privately collected data.

      It's invasively happening on the internet already with advertisers and marketing... it will eventually hit the streets. I suspect many retailers are or have already been experimenting with these techniques. Right now, the computational power and sensor cost requirement are probably too high for ROI but that will definitely change and costs lower, and that's just retail.
