Fingerprint data retention | This document neither requires nor precludes agencies from retaining fingerprint images. However, if an agency elects to retain images, then they shall be stored in the format specified in section 3.5. The format specification includes the | |

Fingerprint image acquisition | This section specifies the capture of a full set of fingerprint images for PIV registration. A subject's fingerprints shall be collected according to any of the three imaging modes enumerated in Table 1. Table 1: Fingerprint acquisition pr | |

Fingerprint template specifications | This section specifies how the PIV mandatory biometric elements specified in [FIPS] are to be generated and stored. This specification applies to templates stored within the PIV Card, and to [MINUSTD] templates otherwise retained by agencie | |
| 3.4.1 in 3.4 |
Source images | Two [MINUSTD] fingerprint templates shall be stored on the PIV Card; these are hereafter referred to as PIV Card templates. These shall be prepared from images of the primary and secondary fingers (as specified in [FIPS]). These images shal | |

Card Issuance | When a PIV Card is issued, one or more authentication attempts shall be executed per [FIPS, 5.3.1]. This shall entail capture of new live fingerprints of both the primary and secondary fingers, and matching of those with the PIV Card templa | |
| 3.4.3 in 3.4 |
Minutia record | PIV Card templates shall be a conformant instance of the INCITS 378-2004 [MINUSTD] minutiae template standard. That is, the minutiae from both the primary and secondary fingers shall reside within a single INCITS 378 record. This means that | |

Fingerprint image format for images retained by agencies | This section specifies a common data format record for the retention of the fingerprint images collected in Section 3.2. Specifically fingerprint images enrolled or otherwise retained by agencies shall be formatted according to the INCITS 3 | |

| 5 | Images shall either be uncompressed or compressed using an implementation of the Wavelet Scalar Quantization | (WSQ) algorithm that has been certified by the FBI. The FBI's current requirement for a 15:1 nominal compression ratio shall apply. 6. Compression should only be applied after the records required by sections 3.4 and 3.6 have been prepared | |
| 5.1 in 5 |
Scope | [FIPS, Section 4.4.1] requires collection of a facial image from PIV applicants, and indicates that it may be used for generation of the printed image [FIPS, Section 4.1.4.1] and for augmentation of human authentication of the card holder. | |
| 5.2 in 5 |
Acquisition and format | 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] | |
| 6 | Facial images shall be compressed using a compression ratio no higher than 15:1. However, when facial images | are stored on PIV Cards JPEG 2000 should be used with ROI compression. The innermost region should be centered on the face and compressed at no more than 24:1. 7. Face recognition performance is a function of the spatial resolution of the i |
