36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM

Advisory 403.1 General - Exception. Biometrics use biological characteristics for user identification or control. Examples include: fingerprints, retinal or iris patterns, voice, facial features, and blood vessel patterns in the hand. Biometrics restricted to a single biological characteristic pose a significant barrier to individuals who do not possess that biological characteristic. Biometric methods based on dissimilar biological characteristics increase the likelihood that individuals possess at least one of the specified characteristics. Examples of biometrics that rely upon dissimilar biological characteristics are voice recognition and face recognition. Examples of biometrics that rely upon similar biological characteristics are scans that use either thumb or index finger prints. Allowing use of an identification card for authentication is an example of a non-biometric alternative.
