Scope

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.
