| Not OP, but... Fingerprints, as far as most readers are concerned, aren't too difficult to duplicate sufficiently. You can obtain someone's fingerprints from photos, as the German defence minister found out years ago[1]. Also you leave them everywhere and your laptop is likely covered in them. You can't effectively change or revoke them. You can reproduce them with varying levels of success with photoshop, a laser printer, gelatin and some home PCB etching gear. And unlike passwords, there's no 5th amendment right covering them for Yanks. (The latter is debatable for passwords, but is absolutely not for fingerprints.) They may be "good enough" security, depending on your threat model. But they're pretty shit for security, all things considered. [1] https://arstechnica.com/information-technology/2014/12/polit... |
Good point, thank you.
