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