    Not a bad idea, but I was working on a project once that would support user uploaded images and looked into PhotoDNA, but it was an incredible pain in the ass to get access to. I’m surprised that someone hasn’t realized that this should just be free and available. Kind of gross that it is put behind an application/paywall, imo. They’re just hashes and a library to generate the hashes. Why shouldn’t that just be open source and available through the NCMEC?

      Putting it behind a 3rd party API that has registration ensures that the 3rd party that is under contract to report it does so. It isn’t enough just to block it - it needs to be reported too. Google and Cloudflare report it to the proper authorities.

      Additionally, if it was open source, people trying to evade it could just download the open source tool and tweak their images until they come back without getting flagged.

        They could tweak their images regardless. Security through obscurity is never a good solution.

        I can understand the reporting requirement.
