ISO/IEC 39794-2:2023

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.
