Abstract
Various embodiments are generally directed to techniques of generating a unique biometric key, hashing and salting the key, and storing it. Embodiments include techniques to analyze biological information associated with a user and determine one or more biological characteristics from the analyzed information. The biological characteristics may be used to generate a character string unique to the user, which may be used to generate the biometric key based on a cryptographic algorithm. The hash values, salt values, or the hash function may be changed at a predetermined interval.
