Scope:

This document specifies:

— generic extensible data interchange formats for the representation of iris image data: a tagged binary data format based on an extensible specification in ASN.1 and a textual data format based on an XML schema definition that are both capable of holding the same information,
— examples of data record contents,
— application specific requirements, recommendations, and best practices in data acquisition, and — conformance test assertions and conformance test procedures applicable to this document.

The iris image information is stored as:

— an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444-1, or
— an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444-1 that can be cropped around the iris, with the iris at the centre, and which can incorporate region-of-interest masking of non-iris regions.

This document also specifies elements of conformance testing methodology, test assertions, and test procedures, as applicable to this document.

It establishes:

— test assertions pertaining to the structure of the iris image data format, as specified in Clauses 6, 7, 8 and 9 of this document,
— test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and
— semantic test assertions.

The conformance testing methodology specified in this document does not establish:

— tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), or
— tests of conformance of systems that do not produce data records conforming to the requirements of this document.

This document does not establish:

— requirements on the optical specifications of cameras, or
— requirements on photometric properties of iris images, or
— requirements on enrolment processes, workflow and use of iris equipment.

 

Project need:

To align Canadian requirements with those of the respective international standards being proposed for adoption and to maintain alignment between Canadian information and communication technology standards and each respective international standard. This proposed New Standard is being developed at the request of P123 – Technical Committee on Information Technology. It will provide the industry with the latest standards available in the ICT field.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
