- ISO-IEC-19794-2011-Iris Camera Standard

ISO/IEC 19794-2011 Iris Camera Standard (Excerpt from ISO/IEC 19794-2011 - Information Technology - Biometric Data Exchange Formats Part 6: Iris Image Data), the aim of this section is to define a standard for the exchange of iris information, which is one part of the ISO/IEC 19794 series that includes specific definitions of attributes for the data record formats used in the storage and transmission of iris images and certain attributes, as well as standards for consistency. Section 6 of this standard specifies the iris image exchange format for biometric registration, verification, and identification (image information will be stored as a matrix), and all biometric data records that conform to this part of the system can be tested within this scope. The standard also stipulates relevant terms and definitions, symbols and abbreviations, specifications for iris image content, specifications for iris image formats, and the selection and related parameters of camera lenses.
