Introduction

Biometric-based authentication systems and applications are expected to support multiple biometric devices from different vendors. male

The Biometric Exchange Format Framework (CBEFF) facilitates biometric data exchange developed by different vendors by simplifying the exchange of biometric data.

Interoperability of signature recognition applications and systems.

GB/T 28826 "Information Technology Public Biometric Identification Interchange Format Framework" is proposed to be composed of 4 parts.

--- Part 1.Data element specification. The aim is to define a standardized project enabling the exchange of biometric data.

--- Part 2.Operating procedures for biometric registration agencies. The purpose is to stipulate the biometric identification registration mark used in the country

Requirements for identifiers, registration agencies, registration procedures, registration applications, and registration maintenance.

--- Part 3.Maintainer format specification. The purpose is to CBEFF biometric identification organization ISO /IEC JTC1/SC37

Defined and described according to the three maintainer format specifications registered in ISO /IEC 19785-2.

--- Part 4.Security block format specification. The purpose is to CBEFF biometric identification organization ISO /IEC JTC1/SC37

Two security block formats defined and registered according to ISO /IEC 19785-2, and the National Information Technology Standardization Committee biological

A type defined by the Feature Recognition Subcommittee (SAC/TC28/SC37) and registered according to GB/T 28826.2-2020

The security block format specification is described.

This document, as part 4 of CBEFF, specifies the integrity and encryption of biometric data. for biometric authentication and

Determines whether to encrypt biometric data.

In order to ensure interoperability, the Common Biometric Exchange Format Framework (CBEFF) is specified in GB/T 28826.1, which is used to convert metadata

The data is associated with one or more Biometric Data Blocks (BDBs). Integrity and encryption options are defined in GB/T 28826.1, and

The concept of a security block (SB) that contains security information related to these options, but does not specify the format and details of the security block.

Starting with a CBEFF maintainer format, there are the following points.

First, if the maintainer format determines the CBEFF data element CBEFF_BDB_encryption_options(biometric data

block encryption option) is specified as NOENCRYPTION (no encryption), and the CBEFF data element CBEFF_BIR_integ-

If rity_options (biometric information record integrity options) is specified as NOINTEGRITY (incomplete), the format of the maintainer does not need

Ask for a safe block.

Second, if the maintainer format needs to include security blocks in some cases, the maintainer format can specify it as a

One of the defined secure block formats or other secure block formats, or may contain the CBEFF data element CBEFF_SB_

format_owner (secure block format owner) and CBEFF_SB_format_type (secure block format type), to identify the use of this

Some secure block format defined by the file, or some other secure block format.

Finally, in addition to the security block formats specified in this document, there may be many CBEFF security block formats that meet different needs. E.g,

Security block format defined in ISO /IEC 24713-3 for the ILO Seafarer Profile. Completion of the security block format for international registrations

This document gives three commonly used security block formats. general security block format, security block format containing only signature and domestic commercial cipher

Generic security block format.

The first security block format is the general security block format, which is designed to be as general as possible. The format adopts RFC3852 encrypted message syntax

(CMS), contains optional elements for encryption and integrity, and supports EnvelopedData, EncryptedData, RFC3852

Require. The Common Security Block format can also optionally include authentication on the biometric (ACBio) instance specified in ISO /IEC 24761

below. ACBio also uses the RFC3852 encrypted message syntax scheme. By including an ACBio instance, it can be determined to generate an authentication bio

part.

The second secure block format is the signature-only secure block format, also defined using RFC3852.

The third security block format is the general security block format of domestic commercial ciphers defined by the domestic commercial cipher message syntax, including

Optional elements for encryption and integrity, not supported for ACBio instances.

Part 4.Security block format specification

1 Scope

This document gives the biometric identification organization ISO /IEC JTC1/SC37 defined by CBEFF, according to ISO /IEC 19785-2

Two registered security block formats, and the registered security block format identifier is given.

NOTE. The security block format identifier is recorded in the SBH of the maintainer format (or is defined by that maintainer format as the only available security block format).

The general security block format provides the specification of whether the BDB is encrypted and whether the SBH and BDB need integrity verification. The format adopts

The international RFC series of cryptographic message syntaxes can also contain instances of ACBio according to ISO /IEC 24761.The security block contains the encryption and/or

or all necessary security parameters including integrity.

It does not restrict the algorithms and parameters used for encryption or integrity, but provides a way how to document the values of such algorithms and parameters.

For a specific application field, how to determine which algorithms and parameter ranges can be used by the security block generator, so as to determine the security block usage

The range of algorithms and parameters to be supported by the author is a matter of analysis and beyond the scope of this document.

The signature-only security block format is similar to the general security block format, although more restrictive, but simpler, in particular it cannot contain

ACBio instances, also do not support BDB encryption.

This document also gives a security block format defined by SAC/TC28/SC37 and registered according to GB/T 28826.2-2020.

Common security block format for domestic commercial ciphers.
