Standardization of common content, meaning, and representation of a modality's biometric data format.
GB/T 26237 supports interoperability and data exchange between biometric applications and systems. This series of standards stipulates
Complexity requirements for applying biometric technology to different classes of identification applications, whether in open system

systems for data exchange and interoperability.
Biometric data exchange format standards and biometric interface standards are important for realizing biometric identification in an open system environment.
Both complete data exchange and interoperability are required. Biometric identification standards include different levels of standards, from biometric identification

The Biometric Data Interchange Format standard specifies a biometric data exchange format for the different biometric modalities.
Parties conforming to the biometric data exchange format specified in GB/T 26237 should be able to conduct mutual biometric data
decoding.
Biometrics interface standards include GB/T 28826 (all parts) "Information Technology Common Biometrics Interchange Format Frame

The biometric profile standard promotes basic standards for defining application domains (e.g., SAC/TC28/SC37 Biometric
