BS ISO/IEC 19785-1:2020

What is ISO/IEC 19785-1 about?  

ISO/IEC 19785-1 define: 

• 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 

ISO/IEC 19785-1 describes methods to define CBEFF patron formats using CBEFF data elements to specify the structure of BIRs, including the standard biometric headers (SBHs). 

ISO/IEC 19785-1 provides the means for identification of BDB formats in a BIR, but the standardization and interoperability of BDB formats. 

ISO/IEC 19785-1 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.  

ISO/IEC 19785-1 specifies transformations from one CBEFF patron format to a different CBEFF patron format. 

Who is ISO/IEC 19785-1 for? 

ISO/IEC 19785-1 on Common Biometric Exchange Formats Framework is useful for:  

• IT companies 
• Banks 
• Healthcare department 
• Government organisations 

Why should you use ISO/IEC 19785-1?  

The primary purpose of CBEFF is to define abstract data that are expected to be of general utility as parts of the SBH in BIRs. ISO/IEC 19785-1 defines these data elements. 

A CBEFF BDB format owner defines one or more BDB formats and assigns a unique BDB format identifier. 

ISO/IEC 19785-1 provides a simple CBEFF BIR structure, a complex CBEFF BIR structure, and a multiple CBEFF BIR structure and gives their requirements. for the specification of a CBEFF patron format based on these abstract data structures. 

ISO/IEC 19785-1 specifies a self-identifying concept that can be applied to all CBEFF BIR structures so that the patron format can be identified during the processing of the SBH without prior knowledge of the patron format type. 

CBEFF also defines the concept of a CBEFF security block format owner. A CBEFF SB format owner is an organization registered as a CBEFF biometric organization that assigns an SB format identifier to an SB format. 

What’s changed since the last update?  

BS ISO/IEC 19785-1:2020 supersedes BS ISO/IEC 19785‑1:2015. BS ISO/IEC 19785-1:2020 includes some technical changes with respect to BS ISO/IEC 19785‑1:2015. These include: 

• The self-identifying concept is now permitted to be applied to any of the CBEFF BIR patron formats defined in this document 
• Clarification of presentation attack detection (PAD) terminology has been made 
• Revisions have been made to move a large portion of Clause 6 (Biometric Identifiers) to ISO/IEC 19785-2 since the biometric identifiers are used by the Biometric Registration Authority (BRA) 
• Previous versions of this document were published by the US National Institute of Standards and Technology (an agency of the government of the United States of America) and the Biometric Consortium Working Group. The last official non-ISO/IEC release of this document was designated Version 1.1, the first version of this document (ISO/IEC 19785-1:2006) was designated Version 2.0, and the ISO/IEC 19785-1:2015 version was designated Version 3.0. This version of the document is designated Version 4.0 to distinguish the versions of CBEFF products in the marketplace. Version 4.0 is backwards compatible with Version 3.0, but the data element names related to PAD have changed.
