A system and method for generating an encryption key using physical characteristics of a biometric sample is described. In one embodiment, the biometric feature(s) from a sample are analyzed to generate a feature vector. After discretizing the feature(s), the resultant feature vector is translated into a bit vector. The bit vector is the secure biometric key that results from the biometric(s). The secure biometric key is used to generate at least one cryptographic key. A similar process is used to access the cryptographic key secured by the secure biometric key. If the access biometric key matches the secure biometric key, the cryptographic key is revealed and access is allowed. In another embodiment, if the access biometric key does not match the secure biometric key a camouflaging process is used to provide an unauthorized user a bogus secure biometric key indistinguishable from the correct secure biometric key.
