I suspect this would be solved by visually comparing the two images and noticing that they are one in the same. Than you can just see which had their hash published on the block-chain first to see which is the real one.
- sgt101 9y agoYes, but if you can identify an image in that way then you can claim the copyright anyway. Searching for copyright violation is the challenge.

- jncraton 9y agoThat would only work if the knockoff image is registered on-chain after the real image. If I'm going to rip off an image, I'm not going to submit it back to the entity that created it. Hashes don't verify the date that something was created. The blockchain provides a date for the hash, but it provides no guarantee that the hashed item didn't exist long before when it first appeared on chain. If I simply modify the image metadata to say that my knockoff photo was taken at an earlier date and flip some bits, I can still claim that mine is the original and that I didn't submit it to the blockchain when I created it.
- sgt101 9y agoI don't think you need a blockchain to do that; just a data base. I don't think that the courts would even need a hash - just evidence that a photo had been made at a time, that it was stored somewhere would be a bonus.
