Sorry I'm still confused. Do you have a reliable way to detect if a smart glass is recording or not? I never used smart-glasses regularly, but wouldn't it be "on" all the time if one is using it, so detecting the power-on and pairing is kinda useless?

Regular pairing, advertising and control likley use Bluetooth LE for simplicity and battery life. Streaming or transferring video likley use Bluetooth classic for increased bandwidth.

These are two different protocols with different radio behaviour.

So beyond detecting the glasses themselves, which seem like the focus of the project; detecting recording is feasible at the point of transfer to a phone.

The issue is distinguishing it from any other high bandwidth Bluetooth device nearby, such as headphones.

A much-needed project. Making yourself invisible to such privacy-invasive devices will be the need of the day. Of the two approaches you mentioned, blocking/jamming the specific wireless traffic would be pretty interesting, if possible.

And probably highly illegal.

Earlier quoted context omitted.

Isn't the biggest mobile use case where you don't want to be secretly recorded in public? This was a big concern with the original Google Glass.

The idea of being constantly monitored by a megacorp tracking all my movements wih their swarm of cameras to feed us personalized ads is utterly dystopian indeed. But I think the only valid way yo prevent this will be legislation though, it's not a fight individuals can win on their own.

It will need both. Secretly recording in the public is already prohibited in many if not most jurisdictions, but ad far as I know, not really prosecuted.

Interesting idea. It seems to me that most things which would need to be protected from hidden cameras would be stationary and not require the operator to mount the detectors on his body, but starting with mobile constraints is often helpful. I would like to draw attention to this gem of wit, easily the best I've seen in a long time: > I think the idea behind this approach is sound (actually it's light)

I could see these being worn by walking-around security in a place where filming by the audience isn’t allowed. Super cool.

Does anyone work on smart glasses for blind people yet? Something with blackened glass, obviously, that uses image recognition to translate visual input into text via (headphone) audio to the wearer. That would allow for urgent warnings (approaching a street, walking towards obstacle [say, an electric scooter or a fence]), scene descriptions on request, or help finding things in the view field. There's probably a lot…

If the top-level poster succeeds, the resulting device could possibly disable devices that allow blind people to see. This could open up another liability channel.

I remember seeing some celebrities in the late 00s / early 10s with IR-emitting sunglasses or accessories to flood the camera sensors of paparazzi and make it harder for photographers to get spyshots of them. Would this approach work for these camera glasses as well, simply flooding them with so much IR spectrum light that their sensors simply can't see you anymore?

Well, there's https://www.nii.ac.jp/userimg/press_details_20121212.pdf I think fooling facial recognition systems and CCTV-cameras-at-night is easier than fooling professional photographers. Most photograhers' cameras have IR filters, after all. And nobody's got an LED brighter than the sun.

It's low density silly fun but I did see these folk attempt to do such a thing with entertaining results https://youtu.be/m1S1r9I6DN4

On this topic, is there any benefit of trying to fool facial recognition systems with these type of accessories and or wearables, would the system not just mark you as suspicious and keep an even better track of you

Of course it is a different thing if these are adopted by the masses
