The fingerprint hash (fingerprint's fingerprint) has to be resistant to rotation/translation, area size and subpattern presence, and tolerate some skin lesion noise, so it's the very opposite of a cryptographic hash. Probably quite easy to reverse. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
