So I had researched it a while ago and don’t recall having found anything effective and non-suspicious to protect from public camera mass survaillence in cities and the like. Is there anything that is a good option for that yet, and if so, could you point me toward it?
Just as normal sunglasse don’t fool facial recognition systems, modern gait recognition systems can’t be defeated by “just altering how you walk”. You can read more about it on The Hitchhikers Guide to Online Anonymity. There is this research paper.
They link a specific device which can fool some systems, but a bit easier (although more inefficient) is just wearing very loose clothes that cover the movement of your muscles.
