ANSI/NIST-ITL 1-2011 Requirements and Conformance Test Assertions



Christofer J. McGinnis, Dylan J. Yaga, Fernando L. Podio


The current version of the ANSI/NIST-ITL standard "Data Format for the Interchange of Fingerprint, Facial & Other Biometric Information" is specified in two parts. Part 1, ANSI/NIST-ITL 1-2007, specifies the traditional format, and Part 2, ANSI/NIST-ITL 2-2008, specifies a NIEM-conformant XML format. Both parts have been combined into one document, which is being revised and augmented. The Computer Security Division (CSD) of NIST/ITL has developed a set of test assertions based on the requirements specified in the 4th draft of the new ANSI/NIST-ITL standard. Over twelve hundred test assertions have been identified and organized into a set of tables to assist in the development of a conformance test tool designed to test implementations of the new version of the ANSI/NIST-ITL standard for selected record types. These tables were contributed to the Conformance Testing Methodology (CTM) Working Group which was recently established by NIST/ITL to develop a CTM for the new version of the ANSI/NIST-ITL (AN-2011) standard. A ballot was conducted on a revised draft (5th draft) of the AN-2011 standard. A new draft will be developed based on the comments received as a result of this ballot. As the technical content of the AN-2011 draft standard evolves towards approval and publication, and comments on the assertion tables in this document are received, revised versions of these tables will be developed until they fully address the requirements of the approved AN-2011 standard. This publication documents the assertions developed and the terms, operands, and operators used in defining these assertions. Brief information on previous and ongoing conformance test tools development within NIST/ITL CSD is included.
