Yup, PDQ (https://github.com/facebook/ThreatExchange/tree/main/pdq) and MD5- https://stopncii.org/faq/. MD5 is a cryptographic hash, which means that even a single bit changed gives you an entirely different hash. This usually precludes any attacks to try and deliberately generate collisions, but also means it's harder to match “benign” changes - for example, many platforms re-encode videos as part of the upload process (reducing resolution, changing formats, etc). However, many platforms skip re-encoding, so MD5 can have better results than you might think at first glance. The more bits you take from the original content, the harder you can make it to bypass, but the more you might have to worry about capturing enough that you might compromise the privacy of the original submitter. For the program, StopNCII picked a set of tradeoffs between those two tensions, and are keeping a close eye on how effective it is, and will iterate if need be.
