There are ways to prevent facial recognition presently, including interfering with the reflected light from the face, which is what facial recognition cameras base their analysis on. A ballcap with leds on the brim does this. However, as with all technologies, things proceed apace, and the cameras will improve in time. An arms race of sorts may last for a while, but in the end facial recognition will triumph, whether we like who is doing the recognizing or not, simply because cameras will improve forever.

So, the cameras aren't the key. Who has access to the cameras, and what they do with the information, is.

I have long ago pointed out that facial recognition, surveillance, and etc., are inevitable, and can be a very good thing - if we use it right. That means using it on criminals who are committing crimes, and not to oppress people expressing their political choices, or other reasons. Given that the means of acquiring images and applying facial recognition software for law enforcement purposes is presently being controlled by politicians an polities that are vectors for a lot of corruption and criminal activity, I reckon that this technology is in the wrong hands presently.

We should get cameras and surveil politicians and government agents, upload the data to the blockchain, and allow public auditing. By crowdsourcing this data and parsing it in a verfiable public source, we can then prove that these criminals are committing crimes like corruption and brutality.

This is the only realistic option that we can undertake given the reality of this technology. We can't stop cameras from improving, and we can't stop them from recognizing us. But we can use the same technology to get rid of the criminal psychopaths abusing political power, and make our laws actually work.

Thanks!
