NIST/ITL CSD Biometric Conformance Test Software (BioCTS) tests implementations for conformance to various biometric data interchange format standards. BioCTS for ISO/IEC tests for conformance to selected biometric standards developed by ISO/IEC JTC 1/SC 37 - Biometrics and PIV profiles. BioCTS for ANSI/NIST-ITL 1-2011 and ANSI/NIST-ITL 1-2011 Update: 2013 tests for conformance to selected Record Types of the ANSI/NIST-ITL 1-2011 standard and the ANSI/NIST-ITL 1-2011 Update: 2013 respectively.

To download a specific version of BioCTS and the associated documentation, select the applicable panel below. For legacy software, including the Conformance Test Architecture (CTA) and Conformance Test Suite (CTS) for implementations of the ANSI/NIST-ITL 1-2007 standard and the CTA and CTSs for biometric data interchange format standards developed by INCITS M1 - Biometrics, see the links in the side panel.

NIST/ITL Computer Security Division (CSD) supports the development of national and international biometric standards and promotes conformity assessment through:  

  • Participation in the development of biometric standards
  • Sponsorship of conformance testing methodology standard projects
  • Development of associated conformance test architectures and test suites
  • Leadership in national and international standards development bodies


Need for Conformance Testing

Conformance testing captures the technical description of a standard and measures whether an implementation faithfully implements the standard. Read more.

Software Description

BioCTS includes several features for testing implementations for conformance to biometric standards, including:
  • Batch testing: allows a large number of implementations to be tested quickly.
  • Editor: allows data to be edited, retested, and saved in order to make failing files compliant.
  • Detailed results: results feature pass/fail/warning messages, test names, and descriptions when appropriate. The editor allows the results to be displayed in a hierarchical, expandable format.
