AS ISO/IEC 19794.10:2024 identically adopts ISO/IEC 19794 10:2007, which specifies a data record interchange format for storing, recording and transmitting the information from one or more hand silhouettes within a Common Biometric Exchange Formats Framework (CBEFF) data structure. It defines the content, format and units of measurement for the exchange of hand silhouette data that may be used in the verification or identification process of a subject.
