I don't think they can leak biometric data. Even if they figure out the hashing algo that doesn't mean they can invert someone's hash.

- ryanisnan 5y agoI don't think that's the rub. The issue is that with a hash and the algorithm, you can reproduce the hash. I think opponents to this are advising against having the retinal hashes in the first place, to eliminate their abuse in the future.
- Traster 5y agoYou don't need to invert it, if the hash is used to issue a token on a centralized system you can ping the centralized system. At minimum you can establish whether someone has an existing account, and at maximum you could identify that account.
