Except if that someone changes a single bit in the photo data (which will result in a completely different hash).
- lightbyte 9y agoThat won't stop you from visually identifying that they are the same, then just looking at the block-chain to see which hash was published first (and thus the real photo).
- fl0wenol 9y agoUnless there's a parallel repository of all the images in a form that's easy to search (some kind of sparse, feature-rich form that's quick CV-match friendly), which isn't the hash, you're going to have a hard time with that initial assessment and enforcement of potential infringers. That right there could be a pretty expensive system to maintain and it isn't ideal to distributed across a bunch of blockchain participants, it probably has to live in a Kodak server farm somewhere.
- runeks 9y agoBut who will determine whether two different images are visually the same? What’s the point of a decentralized system if a trusted third party decides which images are visually equivalent? Just use that third party to register the image with in the first place, rather than in a blockchain, since that party gets to invalidate your image-hash in the chain anyway (in case your image is deemed visually equivalent to an image earlier in the chain).
