Complex Type EPBiometricsType

Control

The following schema fragment defines the EPBiometricsType complex type:

<xs:complexType name="EPBiometricsType"> <xs:sequence> <xs:element name="Photo" type="xs:base64Binary" minOccurs="1" maxOccurs="1"/> <xs:element name="FingerprintOffCardComparisonRepresentation" type="xs:base64Binary" minOccurs="1" maxOccurs="1" /> <xs:element name="FingerprintOnCardComparisonRepresentation" type="xs:base64Binary" minOccurs="0" maxOccurs="1"/> <xs:element name="IrisRepresentation" type="xs:base64Binary" minOccurs="0" maxOccurs="1"/> </xs:sequence> </xs:complexType>

The EPBiometrics complex type contains information related to the biometric data of the subject of the chain-of-trust enrollment record, as captured during PIV enrollment including the primary and secondary fingerprint representation. The four elements supported in the EPBiometrics complex type are:

<Photo>: This element is required. The <Photo> element contains the facial image collected during the enrollment process, as documented in [ SP800-76 ] Biometric Specifications for Personal Identity Verification. The <Photo> element includes the CBEFF Header, the INCITS 385 profile for PIV facial images, and the CBEFF signature. The facial image is used to both print the image on the card and as the digital representation stored in the PIV Card. The data is provided in an xs:base64Binary format. <FingerprintsOffCardComparisonRepresentation>: This element is mandatory and occurs only once. The <FingerprintsOffCardComparisonRepresentation> element contains the fingerprint data collected during the enrollment process and is used for off- card comparison, as documented in [ SP800-76 ]. The <FingerprintsOffCardComparisonRepresentation> element includes the CBEFF Header, the INCITS 378 Minutiae, and the CBEFF signature. The data is provided in an xs:base64Binary format.

<FingerprintsOnCardComparisonRepresentation>: This element is optional and if used occurs once. <FingerprintsOnCardComparisonRepresentation> element is only used if the <FingerprintsOnCardComparisonRepresentation> element uses different fingers representation than in <FingerprintsOffCardComparisonRepresentation> element. If the fingers for on-card and off-card comparison representation are identical, on-card comparison minutia templates representation can be created using the data stored in the <FingerprintsOffCardComparsionRepresentation> element. If used, the <FingerprintsOnCardComparisonRepresentation> includes the CBEFF Header, the ISO/IEC 19794-2:2011 minutiae, and the CBEFF signature, as documented in [ SP800-76 ]. The data is provided in an xs:base64Binary format.

<IrisRepresentation>: This element is optional and if used occurs once. The <IrisRepresentation> element contains the iris image representation collected during the enrollment process, as documented in [ SP800-76 ]. The <IrisRepresentation> element includes the CBEFF Header, ISO 19794-6 iris, and the CBEFF signature. The data is provided in an xs:base64Binary format.
