I really hope that what gets stored and transmitted is a hash or some sort of meta-data generated using my fingerprint and not a scan of the actual print.

- jaekwon 13y agoDoubt it, for something as analog as a finger print, I'm having a hard time imagining a one-way hash function.
- diydsp 13y agoThis made me curious, so I found things like this: www.cse.unr.edu/~bebis/UdayFingerprint.pdf and www.csis.pace.edu/~ctappert/dps/IJCB2011/papers/200.pdf The features themselves are somewhat of a hash of the image, and as quantizable elements, they could be further hashed.
