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?

If I wear boots, sneakers, sandals, hiking shoes sometimes I wonder if it will be enough to throw it off? How distinctly will it be able to tell from millions of gait patterns? Sure it may work foolproof for a set of 100 even intentionally trying to vary things, but how similar will the gait of Roberto Ramirez be to himself the next week or to the hundreds of thousands of people going past an area over a year?

As I recall yes. When the tech was new several years ago, just wearing flip-flops or jandels or whatever-you-call-them was enough to completely throw it off.

I definitively walk differently in e.g., Birks, generic sandals, and generic slip-on closed-toe shoes.

Each one is quite consistent and recognizable, unfortunately, which puts me in a position of few options for working around this sort of technology. If you see me in Birks a decade ago, you'll know me in Birks today without having to see anything above my hip.

I mean I defiantly walk different in flat bottom shoes vs something with a heel like running shoes or boots, I'd guess it should be enough
