CSA Preface<\/strong><\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

For brevity, this Standard will be referred to as CSA ISO\/IEC 39794-6 throughout.<\/p>\n

<\/p>\n

The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. 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.<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

This document specifies:<\/p>\n

<\/p>\n

\u2014 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,<\/p>\n

<\/p>\n

\u2014 examples of data record contents,<\/p>\n

<\/p>\n

\u2014 application specific requirements, recommendations, and best practices in data acquisition, and<\/p>\n

<\/p>\n

\u2014 conformance test assertions and conformance test procedures applicable to this document.<\/p>\n

<\/p>\n

The iris image information is stored as:<\/p>\n

<\/p>\n

\u2014 an array of intensity values optionally compressed with ISO\/IEC 15948 or ISO\/IEC 15444-1, or<\/p>\n

<\/p>\n

\u2014 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.<\/p>\n

<\/p>\n

This document also specifies elements of conformance testing methodology, test assertions, and test procedures, as applicable to this document.<\/p>\n

<\/p>\n

It establishes:<\/p>\n

<\/p>\n

\u2014 test assertions pertaining to the structure of the iris image data format, as specified in Clauses 6, 7, 8 and 9 of this document,<\/p>\n

<\/p>\n

\u2014 test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and<\/p>\n

<\/p>\n

\u2014 semantic test assertions.<\/p>\n

<\/p>\n

The conformance testing methodology specified in this document does not establish:<\/p>\n

<\/p>\n

\u2014 tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), or<\/p>\n

<\/p>\n

\u2014 tests of conformance of systems that do not produce data records conforming to the requirements of this document.<\/p>\n

<\/p>\n

This document does not establish:<\/p>\n

<\/p>\n

\u2014 requirements on the optical specifications of cameras, or<\/p>\n

<\/p>\n

\u2014 requirements on photometric properties of iris images, or<\/p>\n

<\/p>\n

\u2014 requirements on enrolment processes, workflow and use of iris equipment.<\/p>\n","protected":false},"excerpt":{"rendered":"
