Today, when one thinks of a biometrics system architecture including both BioAPI and X9.84, the latter is usually viewed as addressing security issues for the *transmission* of biometric samples and templates. Unfortunately, once the data is received or before it is sent, it lives within the domain of BioAPI and outside the applicability of X9.84. However, for many applications it would be beneficial if these two standards were integrated more tightly. One solution would be to extend the BioAPI standard to allow the use of an X9.84 data block (an "encoded" BiometricSyntax value) in place of a BIR (or as a new kind of BIR), as Phil suggests. Among the benefits is the possibility of storing in a template database a digitally-signed biometric template that keeps the signature of the original signer, with which the data was received. The signature could then be checked at any time, both when the template is received from the network and when it is retrieved from the database months or years later.
