For NFTs that are copies of other NFTs we go with the general idea that the oldest (first) similar result is likely the original. This is an area where the blockchain as a fundamental time stamped ledger is very useful. In cases where an NFT is stolen from existing web content (happens A LOT) our version of the API (with auth) integrates search results from the Tineye API. These searches are relatively expensive so with the initial release we put them behind an API key. That may change. In terms of copyright violations... We've talked to a lot of lawyers in the space and it breaks down into two broad categories: 1) Straight up infringement. This is anything with a (roughly) 94% or greater pixel match. In terms of copyright this is an open and shut case for infringement. 2) Some kind of derivative work... Whether a well intentioned remix of another work or a deliberate attempt to avoid detection or cause confusion we haven't yet received hard legal guidance on where this line falls algorithmically. 3) A new work that's visually similar. Again, not sure what the computer vision approach is here. In any case it comes down to "What can you do about it?". First steps are making sure people don't buy it and creators are aware of it. Next steps (working on this!) are getting this content off NFT marketplaces. That can come either through cooperation with them or automatically serving DNCA take downs to content hosts (problematic with IPFS, etc).
