Police unions would love for cameras to standardize on that.

There was an article on HN that one city's police force, when there were protests going on, took to playing Disney songs from loudspeakers; so that any recording of their interactions would be impossible to publish on any significant internet platform (or at least, the audio would be muted, by IP protection filters).

Rendering security cameras useless for identifying any criminals?

Maybe some of these commenters aren’t old enough to remember when fighting for your right to take photographs and videos in public places was one of the frequent topics in online places like Slashdot and BoingBoing. There have been waves of attempts to restrict freedoms to take photos in many countries. When they pass there’s a significant loss of personal rights and freedoms.

> Similarly, a venue could request a do-not-film-this-venue setting and make sure no photos are taken at a party.

Do you really want this? An off-button for all cameras nearby? Please purchase your official photographs from the gift shop or from the $5 Photo Booth.

This would be a dream for bad people who don’t want to be recorded or photographed doing something, like a bad police officer. Just keep a device around that broadcasts the “do not record at this venue” signal and you can shut down recordings all around.

> All cameras (glasses, phones, etc.) then blur your face in recordings.

that requires too much goodwill and effort from the makers of such devices. They know their audience wouldn't want that. They don't give a shit about what people being filmed think.

Not too dissimilar to the Black Mirror episode "White Christmas" where you can block other people in real life. Except in this case it's glasses and in Black Mirror retinal implants. We're getting there.

Yes. And an app could render the same thing on your screen via the same tech currently used to robustly watermark generative AI image output, and now not only you won't be able to screenshot the app, you also won't be able to take a photo of it with another device, and on the off chance you found some pre-202X camera that still could, no other computer would display the resulting photo either.

Yes, let's keep coming with more of these great ideas.

To cut this short: the whole overall idea is just universal DRM writ large. A big, principled no fucking way, ever from me.

But what about the personal privacy / venue rights ...

That's a social problem, it should not be used as excuse to give unilateral control over other people's technology to groups or individuals with special interests.

Great idea, we could also have a standard in browsers that signals you don't want to be tracked. We could call it the "Do not track" header, short for DNT.

It would make sure no websites track you.

I remember there was a patent from Apple for a QR-code which would cause devices to stop filming when it's detected...

The idea was for concert venues display these on-stage to block smartphones from filming (and redirect users to iTunes purchases instead IIRC)

And what happens when some bad actor actively monitors for that signal and seeks out the people who have it? And why does it require carrying my surveillance device to tell others I don't want to be surveilled?

> hash of your facial biometrics via Bluetooth

Sounds like a swift way to be included in "Need constant observation" list. Or we can even build a special surveillance for such folks along with plausible Parallel construction scenario constantly refreshed.

Why not make filming opt-in rather than opt-out?

Why do we need a standard for something that should socially be the norm?

And now you’re a walking antenna broadcasting your face/biometric ID hash to anyone in range.

Sounds a lot worse. The possible applications of this alone are infinitely more scary than perverts filming others without their consent.

This is THE nightmare scenario. Think about it for a second and you’ll see why.

there was a black mirror episode on something similar IIRC

These are social problems not technology problems.

We want a society that does not need these workarounds.
