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 9 . Because [FACESTD] is generic across applications it includes either-or requirements. Table 12 is an application profile of [FACESTD] tailored for PIV. It gives concrete specifications for much of the generic content. Column 3 references [FACESTD] and columns 4 and 5 give [FACESTD] requirements. For PIV, column 6 of Table 12 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, a "values supported column" [ICS, Clause 9.1] should be added by implementers for checking conformance to the specifications. While the INCITS 385 standard has been superseded by the ISO/IEC 19794-5 standard, it is retained here because PIV has used it since inception – see Section 1.6 .
