I am looking for theoretical information on an Encryption system that would encrypt Biometric data before it is sent over a network to a central processing pc. Once the encrypted data is received, it is decrypted, and matched against existing biometric templates - the system then responds according to the results of the matching system?
I am not looking for existing commercial Biometric systems that are advertised, rather, I need theoretical information on how this would work (if there is a commercial company that shows you how this works then that is fine). Also, I would rather it be a simple encryption system, something that is widely available, simple to use and implement and has stood the test of time.
Thanx in advance
