This will cause people to start walking on the street in the same way as Fremen in Frank Herbert's Dune, by varying frequency and step length in order not to attract a (government) worm.

I was thinking more Ministry of Silly Walks.

I'm curious what the false positive rate is on this technology. It seems like a very noisy source to do correlations from.

Doesn't matter. Like polygraph, it only matters if people have a fear of being caught with non-trivial probability.

False-positives don't matter, since China has no civil rights.

This is not new, and is not unique to China. Any country with intelligence units, like the US, is using data mining to identify and control their citizens. It has become fashionable lately to imply that China is the only country doing these things, or somehow doing it in larger scale. Has everyone forgotten what Snowden revealed?

China is doing it at MUCH larger scale and a lot more intrusive. Everything on the internet is tracked and filtered, cameras everywhere. Chinese government can pinpoint location of any of it's 1.3 bln citizens.

Do you have evidence to back up any of that?

China doesn't have near the surveillance infrastructure that the US government does outside of China.

The simple fact that China has more citizens to surveil does not mean China is conducting surveillance on a larger scale.

1. Gait detector is functional. 2. Countermeasure: use stone in the shoe, tape and other things to fool the gait detector. 3. Counter-countermeasure: detect artificial gaits. Everyone unrecognized with artificial gait is person of interest.

> Everyone unrecognized with abnormal gait is person of interest

I'm so glad people like you are building my future.

...says some company. Yeah right. The sensitivity/specificity requirements for this to be useful would be insanely difficult or impossible to reach.

The US government has had this forever. This is why they train you at the farm to put a pebble in your shoe if you’re trying to evade detection so your gait changes. It is most certainly not impossible.

I dont remember anything in the snowden docs about the NSA trying to track the movement of all american citizens. Comparing what the NSA does to what China does is like comparing the treatment of women in the US and Saudi Arabia

Of course, Snowden was only able to review what he saw 5 years ago or more. Why you have any doubts that the NSA, with ample resources to track and control, would use techniques similar to what the Chinese do? Do we really need another Snowden to realize this obvious fact?

Chinese government can kill any citizens anytime they want. If Snowden is born in China, his parents and relatives will be used as hostage or sent into jail.

I'm also very suspect of these claims, we know "forensics" often plays extremely fast and lose with evidence.

The real punchline from that article "no peer reviewed scientific studies have ever been done to prove the basic assumption that every person’s fingerprint is unique."
