Information technology - Extensible biometric data interchange formats - Part 6: Iris image data

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,

-
