Regarding all the chat control posts, I've not seen any comments regarding the potential use for homomorphic encryption to abide by this law: if chat control is only used for the detection of CSAM (which is another issue in itself; Apple, for instance, already solved this with NeuraHash), then could "allowing the government to snoop" be letting them have the homomorphically encrypted ciphertext?
Disclaimer that I actually don't know what the full extent this chat control law is asking for, except for the fact that it will deeply compromise encryption
- sterlind 1y agoso you encrypt your image, send it to the government, the government runs its CSAM detector on the encrypted image and gets... an encrypted result. then what? you decrypt the answer and send it back to them? promise that you totally didn't change the answer? FHE is the wrong tool for the job. you'd want verifiable computation (e.g. ni-ZKP) instead. both are too complex and faaar too computationally expensive for actual use.
