That would be interesting. Then all someone has to do is generate images that collide with the ones in the CSAM hash database and airdrop them to someone, then they’re suddenly the target of a federal investigation. I remember someone posting about a year ago a bunch of strange looking images that produced those collisions. If it’s all E2E then all Apple sees is a matching hash and can’t do any further review other than refer to law enforcement. |

If the hashes are cryptographic, then this is impossible (given today's technology).

The CSAM hash database isn't public AFAIK.

You're probably thinking about their proposed 'perceptive hash', which has since been scrapped.
