Already done for (high-end) photo cameras.
But why store the signature in a blockchain? If you do not trust the certificates in the first place, the storage location won't make any difference. And if you trust the certificates, the storage location is completely irrelevant. Because the certificates alone provide the trust.
- rubicon33 5y agoWell, my thinking was that you would want to store the data cryptographically signed, on a block chain, for the same reasons (more or less) that NFTs exist on a blockchain. Predominately, the public ledger of ownership seems like an important aspect of digital content. Is it necessary for trust? Not at all, but it certainly doesn't hurt it? Disclaimer: I am an armchair crypto fan. Not an authority.
- a1369209993 5y ago> But why store the signature in a blockchain? For the same reason as certificate transparency logs; you want to avoid trusting something that has a history of certifying false statements. You also need to handle throwaways, so it's definitely not sufficient (and might turn out to not be necessary once a complete solution is found), but it does seem useful.
