Humans can be cheaper than robots if properly exploited!

It’s not. Wait till you find out how they made movies before CGI!

A MAC is symmetric and can thus only be verified by you or somebody who you trust to not misuse or leak the key.

You sign them against a known public key, so anybody can verify them.

Regular digital signatures is what’s needed here You can still use such a signing circuit but treat it as an attestation by the camera’s owner, not as independent proof of authenticity.

If it’s just the cameras owner attesting, then just have them sign it. No need for expensive complicated circuits and regulations forcing these into existence.

I think you are misunderstanding things or don’t know shit about cryptography. Why the fuck are y even talking about publicly unlockable encryption, this is a use case for verification like a MAC signature, not any kind of encryption.

And no, your process is wild. The actual answer is just replace the sensor input to the same encryption circuits. That is trivial if you own and have control over your own device. For your scheme to work, personal ownership rights would have to be severely hampered.

All of this could be done without blockchain. Once they sign a signature with their private key they can’t unsign it later. Once you attest something you cannot un-attest it.

Just make the public key known and sign things. Please stop shoehorning blockchain where it doesn’t belong, especially when you aren’t even giving any examples of things that blockchain is doing for you with 100000x the cost and complexity, that normal crypto from the 80s/90s cant do better.

Just because you’re writing this on the fediverse doesn’t mean it’s the answer to everything. It’s certainly not the answer to this.

If you’ve been saying this for a long time please stop. This will solve nothing. It will be trivial to bypass for malicious actors and just hampers normal consumers.

1. Anybody can also verify it if they just host the hash on their own website, or host the video itself.
2. Getting the general populace to understand block chain implementations or how to interface with it is an unrealistic task
3. What does a distributed zero trust model add to something that is inherently centralized requiring trust in only 1 party

Blockchain is the opposite of what you want for this problem, I’m not sure why people bring this up now. People need to take an introductory cryptography course before saying to use blockchain everywhere.

First blame the thief. But then in the same breath blame the manufacturers that refuse to sell cars with meaningfully working locks. If you understand the tech many car companies keep selling cars that have locks that are about as secure as a zip tie.

Bro you can make an ak-47 out of a shovel.

The FGC-9 is a gun designed to be built only from common hardware store tools and a shitty 3d printer and has been used by even the myanmar rebel forces who built it themselves. (Also you can build 3d printers themselves from hardware store and hobbyist electronics store supplies).

Guns are just metal tubes with some extra bits, as knowledge and materials get better, making them gets easier. You’re making this statement like it hasn’t been a common thing for years

Trying to transitively get the world to defederate from everybody you don’t like is a terrible idea. That will just lead to over moderation and the community becoming bland. Everybody will want somebody else defederated from everybody else which will destroy the interconnectedness of the fediverse. Pushed to it’s extreme, citing the paradox of tolerance leada to Nazi or USSR levels of totalitarianism and fascism against any perceived thought crime.

They are defederated, that’s a reasonable measure to get rid of most of it. Now just ignore it.
