A general framework of biometric digital key is required in order to provide enhanced
cryptographic secure authentication and security on telebiometric system. This Recommendation
specifies a framework for biometric digital key generation and protection using biometric template
with Public Key Certificate and Biometric Certificate in order to provide secure authentication
process on open network environments. This Recommendation also describes the security
requirements in biometric digital key generation and protection for providing biometric
authentication and secure communication.
However, this Recommendation does not cover the methodology of biometric digital key generation
in detail because many different kinds of mechanisms can be used for generating and deriving
biometric digital key from biometric template. And it also does not specify the detailed
telebiometric system mechanism on biometric digital key generation and protection as many models
or system architecture can be used on biometric digital key on open network.
