1. A dynamic biometric enrollment system comprising a processor and media memory, the processor configured to:
determine verification match value indicative of whether an at least one biometric authentication sample received from a user matches with a dynamic biometric reference template generated from an at least one biometric enrollment sample;
generate a dynamic enrollment event journal entry, the dynamic enrollment event journal entry comprising a user identifier, the verification match value, and a dynamic biometric reference template identifier uniquely identifying the dynamic biometric reference template;
digitally sign the dynamic enrollment event journal entry using SignedData cryptographic message syntax to generate a SignedData message;
bind the dynamic biometric reference template identifier to the SignedData message via an attribute of the SignedData message;
time stamp the dynamic enrollment event journal entry using a trusted timing authority, wherein the dynamic enrollment event journal entry provides reliability and verifiability of when the dynamic enrollment event journal entry was generated;
store the dynamic biometric reference template if the at least one biometric authentication sample matches with the dynamic biometric reference template; and
associate the dynamic biometric reference template with the user identifier.
