    No, it took a week to refine the attack algorithm, the collision generation itself is fast

    The point of perceptual hashes is to let you check if two things are similar enough after transformations like scaling and reencoding, so you can’t rely on that here

      oh yup that’s a very fair point then! you certainly wouldn’t use it for security in that case, however there are a lot of ways to implement this that don’t rely on the security of the hash function, but just uses it (for example) to point to somewhere in a trusted source to manually validate that they’re the same

      we already have the trust frameworks; that’s unnecessary… we just need to automatically validate (or at least provide automatic verifyability) that a video posted on some 3rd party - probably friendly or at least cooperative - platform represents reality
