GB/T 28826.1-2012Information technology -- Common biometric exchange formats framework -- Part 1: Data element specification (English PDF)

1.1 section defines the structure and data elements biometric information records.

1.2 part defines the concept of using the domain in order to establish compliance with the requirements of the standard or specification CBEFF applicability.

1.3 part defines the concept of physical formats, entity format is specified by the entity, in line with the requirements of CBEFF biometric information note

Format specification recorded.

1.4 part defines a set of abstract values \u200b\u200b(and associated semantics) it can be used to define the data elements CBEFF CBEFF entity format of.

1.5 section details the standard raw CBEFF entity CBEFF data element definitions included in the biometric information record

Biometric identification data head of content and coding (for example, the definition of CBEFF entity format).

1.6 This section provides identification biometric information recording biometric data block format method, but the standard biometric data block

And interoperability is not within the scope of this standard. This standard provides a biometric information so that record biometric data block carry encrypted letter

Interest (security block) method, but security block structure and contents are defined by the entity responsible for CBEFF, and not within the scope of this standard; biological

Specifications Specification and biometric information recording characteristic data integrity mechanisms block encryption mechanism is not within the scope of this standard.

1.7 section details the conversion from one format to another entity CBEFF format CBEFF of different entities.

Encoding abstract values \u200b\u200bused in the 1.8 format specification CBEFF CBEFF entity data element is not within the scope of this standard.

1.9 ISO /IEC 19785-2 specifies the biometric registration authority issuing biometric organization identifier and registration BDB

Format, CBEFF entity compatible format, security block format, biometric products, the acquisition means feature item extraction algorithm, alignment algorithm, quality

The amount of algorithms and compression algorithms operating procedures.

1.10 ISO /IEC 19785-3 specifies the physical format specification several ISO /IEC JTC1SC37CBEFF entity.

1.11 privacy protection, prevent inappropriate use of biometric data and disseminate the provisions of the scope of this section, but may be the case

National regulatory management category.

2.1 a compliant entity shall meet the following criteria.

a) in accordance with this section 6.2 (a simple definition of biometric information record structure) or 6.3 (define complex biometric information record structure)

Requirements defined CBEFF entity format.

b) in the physical format specification should contain.

1) CBEFF entity's name, the name is artificial interpretation;

2) ISO /IEC 19785-2 in biometric registries decimal entity identifier assigned or hexadecimal value;

3) entity format name, which is artificial interpretation;

4) decimal format CBEFF entity entity assigned to the entity identifier format or hexadecimal value;

5) Complete ASN.1 object identifier of the entity format, this identifier should also mark the ASN.1 and XML format;
