ISO/IEC 19794-2:20 05规定了使用细节的基本概念来表示指纹的概念和数据格式。它是通用的，因为它可以在涉及自动指纹识别的广泛应用领域中应用和使用。ISO/IEC 19794-2:20 05包含相关术语的定义、如何确定细节的描述、包含通用数据和卡片数据的数据格式以及一致性信息。信息性附件中提供了匹配和决策参数的指南和值。 ISO/IEC 19794-2:20 05规定 用于指纹的基于细节的表示的基本数据元素；用于交换和存储这些数据的三种数据格式:基于记录的格式，以及用于智能卡上的普通和紧凑格式。卡上应用；可选的扩展数据格式，用于包括附加数据，如脊数、核心和三角洲位置。 ISO/IEC 19794-2:20 05提供了在感测、存储和匹配系统之间交换手指细节数据。

ISO/IEC 19794-2:2005 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. ISO/IEC 19794-2:2005 contains definitions of relevant terms, a description of how minutiae shall be determined, data formats for containing the data for both general use and for use with cards, and conformance information. Guidelines and values for matching and decision parameters are provided in an informative annex. ISO/IEC 19794-2:2005 specifies

• the fundamental data elements used for minutiae-based representation of a fingerprint;
• three data formats for interchange and storage of this data: a record-based format, and normal and compact formats for use on a smart card in a match-on-card application;
• optional extended data formats for including additional data such as ridge counts and core and delta location.

ISO/IEC 19794-2:2005 provides for interchange of finger minutiae data between sensing, storage and matching systems.
