That's what one-way hash functions are for. You never store the raw fingerprint data, just its unique salted hash so the data cannot be reused elsewhere.

- Vraxx 10y agoIt only takes one case of blatant disregard by a trusted source to spoil the entire process. What do you do when the scandal leaks that X Co didn't do due diligence and now 100 million of their customer's brainprints are leaked and able to be compromised?
- heffo 10y agoThat's the same reasoning for text passwords, yet there are huge password dumps every year. It only takes one place where security standards aren't implemented properly to have your print leaked forever. Never mind a malicious user managing to alter the code to leak the print before it's hashed. Or even someone physically accosting you and retrieving a brain scan. They could do the same thing and force you to give up a password, but at least the password you can change later on.

For that matter, a password is always your choice to reveal or not, taking the cost and alternative into account. Biometric information isn't.
- SEJeff 10y agoOr messing with the RNG so that the salt isn't actually random. That would never happen :)
