Representatio d Representation Length MF MV Bytes for this representation including the header + image 9. Capture date and time MF MV 2011 onwards. Capture start time in UTC 10. Capture device technology identifier MF MV

11. Capture device vendor ID MF MV Manufacturer ID 12. Capture device type ID MF MV Vendor assigned make model product ID. 13. Quality block MF MV 0 Zero indicates no quality blocks follow 14. Representation number MF MIT 1 Representation sequence number 15. Eye label MF MIT 0 Undefined which eye 16. Image type MF MV 7 IMAGE_TYPE_CROPPED_AND_MASKED = 7 (07Hex) i.e., a cropped and region-of-interest masked, centered, iris image with (0,6R 0,2R) margins. See NOTE 2 17. Image format MF MV 2 = 0x2 Encoding shall be RAW 18. Iris image properties bit field MF MV 01010101 Bit field values.

19. Image width, W MF MIT 1 Dimensions ranges, in pixels, are implied by the exact [IRISSTD] margin requirements based on iris size. 20. Image height, H MF MIT 1 21. Bit depth MF MV 8 Bit depth in bits per pixel. This shall not be used to indicate compression level 22. Range MF OIT 0 Required field; optionally populated. 23. Roll angle of eye MF OIT 0 Camera or software should estimate roll angle. Rotation should only be applied if angle is > 20 deg. 24. Roll angle uncertainty MF OIT 0 25. Iris centre, lowest X MF MV 0 These values are redundant for Image type = 7 for which image shall be exactly centered. The iris center shall be estimated by the iris localization code, or if necessary by a human inspector. 26. iris centre, highest X MF MV 27. Iris centre, lowest Y MF MV 0 28.

6.4 Iris image specification for iris images retained outside the PIV Card This document neither requires nor precludes agencies from retaining iris images. [FIPS] recommends use of iris imagery (and face in limited cases) in cases where fingerprints cannot be captured satisfactorily. In addition, [FIPS] allows iris whenever fingerprints are used, and indicates that iris image data may be available outside the PIV Card for authentication during PIV Card issuance, re-issuance, and verification data reset transactions. If agencies elect to retain images, they shall be stored in the format specified in this clause. This clause establishes a profile of ISO/IEC 19794-6:2011 suited for retention of iris images outside the PIV Card. The format specification includes the [CBEFF] header of Section 9 , and this requires integrity protection and allows for encryption of the image records. Retention of data supports, for example, detection of duplicate identities.
