a) the data can often be used to recreate a fake fingerprint that isn't identical but will be accepted, sometimes even by systems from different vendors
b) what they actually store varies, and I'm sure some systems do just store the picture (your passport does, for example), some likely don't store it in the database but happen to have a temp folder somewhere with everything they scanned, and some claim they don't store it and then store it under advanced military-grade 512 bit RSA encryption with the key stored next to the images.
The software quality of biometrics systems is among the worst I've seen. Worse even than embedded/IOT stuff.

- lightedman 4y agoWhere I work, we use a fingerprint scanner to clock in/out. My right index and left ring finger are similar enough in their prints that either will work for the device.
- tgsovlerkhgsel 4y agohttps://www.google.com/search?q=reconstruction+of+fingerprint+images+from+minutiae https://www.google.com/search?q=reconstruction+of+fingerprin... has a number of different papers.
- blowski 4y agoThese all seem to be academic studies. I can't see any links that show a fingerprint being reconstructed and then used on a different system.
