Information technology — Extensible biometric data interchange formats — Part 2: Finger minutiae data

This document specifies:

—     generic extensible data interchange formats for the representation of finger minutia data:

—     a tagged binary data format based on an extensible specification in ASN.1,

—     a textual data format based on an XML schema definition that is capable of holding the same information as the tagged binary format, and

—     an on-card biometric comparison format based on extensible TLV encoding;

—     on-card biometric comparison parameters based on extensible TLV encoding for constructing valid probe data in the on-card biometric comparison format;

—     examples of data record contents;

—     application-specific requirements, recommendations and best practices in determining minutiae location, direction and type; and

—     conformance test assertions and conformance test procedures applicable to this document.

NOTE            Whereas ISO/IEC 39794-4 covers finger, palm, toe and foot image data, this document covers only finger minutiae and is not applicable to palms, toes or feet.
