Seewww.biometrics.nist.gov/standard for the content of this field for the encoding254DRAFT 2
ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Informationused. In Traditional encoding, the content is the length of the record. In NIEMconformantencoding it is the record type-number.26.2 Field 99.002: Image designation character / IDCThis mandatory field shall be the IDC of the Type-99 record as found in the filecontent (CNT) field of the Type-1 record.26.3 Field 99.004: Source agency / ORI / SRCThis mandatory ASCII field shall contain the identification of the administration ororganization that originally captured the biometric sample contained in therecord. Normally, the ORI of the agency that captured the image will becontained in this field. The SRC shall be defined by the user and be inaccordance with the receiving agency.26.3.1 Field 99.005: Biometric creation date / BCDThis mandatory ASCII field shall contain the date and time that the biometricsample was captured. The YYYY characters shall represent the year the imagewas captured; the MM characters shall be the tens and units values of the month;the DD characters shall be the tens and units values of the day in the month; thehh characters shall be the tens and units values of the hour of the day in 24-hourformat; the mm characters shall be the tens and units values of the minute withinthe hour; the ss characters shall be the tens and units values of the second of theminute.26.3.2 Field 99.100: CBEFF header version / HDVThis mandatory ASCII field shall be used to identify the version of CBEFFspecification that this record conforms to. The format is two characters for majorversion number followed by two characters for minor version. The currentversion of CBEFF is INCITS 398-2005 represented by the string ‘0101’ (majorversion ‘01’ and minor version ‘01’).26.3.3 Field 99.101: Biometric type / BTYThis mandatory ASCII field shall be used to identify the type of biometrictechnology. This specification adopts the values presented in CBEFF with theaddition of two leading zeros for future expansion. Table 92 lists the currentbiometric type codes.255DRAFT 2Table 92: CBEFF Biometric typeBiometric TypeNameBiometric TypeCodeNo Information Given ‘00000000’Multiple Biometrics Used‘00000001'Facial Features‘00000002'
