Information technology — Common Biometric Exchange Formats Framework — Part 1: Data element specification (Adopted ISO/IEC 19785-1:2020, third edition, 2020-09)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
For brevity, this Standard will be referred to as CSA ISO/IEC 19785-1 throughout.
This Standard supersedes CAN/CSA-ISO/IEC 19785-1:16 (adopted ISO/IEC 19785-1:2015). At the time of publication, ISO/IEC 19785-1:2020 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This document defines:
— structures and data elements for biometric information records (BIRs);
— the concept of a domain of use to establish the applicability of a standard or specification that conforms with CBEFF requirements;
— the concept of a CBEFF patron format, which is a published BIR format specification that complies with CBEFF requirements, specified by a CBEFF patron;
— the abstract values and associated semantics of a set of CBEFF data elements to be used in the definition of CBEFF patron formats;
This document describes methods to define CBEFF patron formats using CBEFF data elements to specify the structure of BIRs, including the standard biometric headers (SBHs).
This document also provides the means for identification of BDB formats in a BIR, but the standardization and interoperability of BDB formats is not within the scope of this document. This document provides a security block (SB) as a means for BIRs to carry information about the encryption of a BDB in the BIR and about integrity mechanisms applied to the BIR itself. The structure and content of SBs is not within the scope of this document. Further, the specification of encryption mechanisms for BDBs and of integrity mechanisms for BIRs is not within the scope of this document.
This document specifies transformations from one CBEFF patron format to a different CBEFF patron format.
The following are not within the scope of this document:
— the encoding of the abstract values of CBEFF data elements to be used in the specification of CBEFF patron formats; and
— protection of the privacy of individuals from inappropriate dissemination and use of biometric data.
