This section provides specifications for the retention of facial images. Facial images collected during PIV Registration shall be formatted such that they conform to INCITS 385-2004 [FACESTD]. In addition to establishing a format, [FACESTD] specifies how a face image should be acquired. This is done to improve image quality and, ultimately, performance. The images shall be embedded within the CBEFF structure defined in Section 6. Because [FACESTD] is generic across applications it includes sections that have either-or requirements. Table 6 is an application profile of [FACESTD] tailored for PIV. It gives concrete specifications for much of the generic content. Column 3 references the sections of [FACESTD] and columns 4 and 5 give [FACESTD] requirements. For PIV, column 6 of Table 6 gives normative practice or value specifications. The table is not conformant with the Implementation Conformance Statement [ICS] standard. Particularly it extends the function of ICS but because it has the needed rows it may be useful in construction of a traditional ICS. Nevertheless the addition of a "values supported column" as specified in Section 9.1 of [ICS] should be used by implementers for checking conformance to the specifications. INCITS 385 is likely to be revised by the INCITS M1 committee. Such revisions are irrelevant to PIV; however implementations should respect the version number on Line 5 of Table 6.
