BS ISO/IEC 19794-2:2011+A2:2015

Information technology. Biometric data interchange formats. Finger minutiae data | Status: Confirmed, Current

1 Scope This part of ISO/IEC 19794 specifies a concept and data formats for representation of fingerprints using the fundamental notion of minutiae. It is generic, in that it may be applied and used in a wide range of application areas where automated fingerprint recognition is involved. This part of ISO/IEC 19794 contains definitions of relevant terms, a description of how minutiae are to be determined, data formats for containing the data for both general use and for use with cards, and conformance information. Guidelines and values for comparing and decision parameters are provided.

NOTE Although ISO/IEC 19794‑4 covers both finger and palm image data, this part of ISO/IEC 19794 only covers finger minutiae and is not applicable to palms.

This part of ISO/IEC 19794 also specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to this part of ISO/IEC 19794. It establishes test assertions pertaining to the structure and internal consistency of the finger minutiae data formats defined in this part of ISO/IEC 19794 (Type A Level 1 and 2 as defined in ISO/IEC 19794‑1:2011 AMD 1) and semantic test assertions (Type A Level 3 as defined in ISO/IEC 19794‑1:2011 AMD 1). The conformance testing methodology specified in this part of ISO/IEC 19794 does not establish:

• — tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security),
• — tests of conformance of systems that do not produce data records conforming to the requirements of this part of ISO/IEC 19794.
