This document defines the general content of the biometric data format, that is, considers the biometric identification of the specific part of GB/T 26237 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 system environment or consist of a single closed system. Open systems are built on standards-based, commonly defined data formats, interfaces, and protocols on the basis of protocols to facilitate data exchange and interoperability with other systems, including components of different designs or manufactures. Closed systems are also available can be built on publicly defined standards and can include components of different designs or manufactures, but need not be intrinsically linked to any other 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 Data exchange formats and biometric interfaces and biometric profiles describing the use of these standards in specific application areas composition. Figure 1 shows the interrelationships among the areas of standardization related to biometric identification. Comply with the biometrics specified in GB/T 26237 Biometric data in an identification data exchange format represents a core component of biometric interoperability. can be used such as The biometric format framework specified in GB/T 28826 is used as a wrapper for biometric data. Since biometric data is sensitive sensitive data and is vulnerable to attack, so encryption protection is required in the exchange environment. About Biometric Profiles, Security Assessments and Sexuality Ability assessment also plays an important role. Biometric interfaces are critical to facilitate easy integration and use of biometric components. suggestion Use an emerging unified vocabulary to describe biometric technologies. The application deployment of biometric verification or identification technology shall comply with social Meeting and judicial requirements. 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 Framework" and GB/T 30267 (all parts) "Information Technology Biometric Application Programming Interface". within these standard support systems or Exchange of biometric data between systems. GB/T 28826 specifies the basic structure of a standardized biometric information record (BIR), where Include biometric data exchange records with additional metadata, such as collection time, expiration date, encryption or not, etc. GB/T 30267 specifies an open system API that supports communication between software applications and basic biometric technology services Communication. The biometric profile standard promotes basic standards for defining application domains (e.g., SAC/TC28/SC37 Biometric implementation of specific data exchange formats and biometric interface standards, and possibly non-biometric standards). These profile standards define the functionality of the application (e.g., physical access control for airport employees), and calls to objects are then regulated in base files to ensure that biological Interoperability of signature recognition. Figure 1 A general model of the interrelationships between areas of biometrics standardization Users of biometric identification systems expect to use this document and other standards to ensure that biometric identification can be Replacement of components of a system with other components from different suppliers and ensuring that biometric data produced by one system can be used by another system use. In order to achieve this goal, it is crucial that systems claiming to be compliant are in fact compliant, so that for Each biometric data exchange format described in GB/T 26237 requires a standardized compliance test method in order to comply with Provide reasonable assurance that the declaration of conformity is valid. Although it is possible to determine whether the individual elements in the data exchange record comply with the relevant requirements, there is no Is there any test that ca......
