3.1.1

basic access protection

BAP

protection method requiring a human-readable and/or machine-readable key/password on the IDL to access the data on the secure IC via protected-channel communication

3.1.2

binary coded decimal

BCD

binary coding of a sequence of integers using 4 bits for each integer (where the bit weights are 8421) and encoding two integers per byte, and where a 0 digit is appended to the left of an integer sequence containing an uneven number of digits before encoding

Note 1 to entry: Only unsigned BCD is used in this document.

Note 2 to entry: For purposes of this document, the definition of numeric characters in ISO/IEC 18013-1 in terms of ISO/IEC 8859-1 is deemed to be for identification purposes of the numeric characters only, and does not pertain to the manner in which numeric characters have to be encoded. Encoding rules are explicitly specified in this document.

3.1.3

biometric data block

BDB

block of data with a defined format that contains one or more biometric samples or biometric templates (3.1.5)

3.1.4

biometric information record

BIR

BioAPI Consortium Patron Format biometric record header

3.1.5

biometric template

biometric sample (i.e. information obtained from a biometric device, either directly or after further processing) or combination of biometric samples that is suitable for storage as a reference for future comparison

Note 1 to entry: This definition is an expansion of a definition in ISO/IEC 19785-1:2015.

3.1.6

card holder

person using an IDL, who is not necessarily the legitimate licence holder

3.1.7

common biometric exchange file format

CBEFF

file format that promotes interoperability of biometric-based applications and systems by specifying a standard structure for a BIR (3.1.4) and a set of abstract data elements and values that can be used to create the header part of a CBEFF-compliant BIR

Note 1 to entry: This definition is based on descriptive language in ISO/IEC 19785-1:2015.

3.1.8

compact encoding

encoding method when the memory capacity available for the IDL application does not exceed 5 kB, typically applicable to 2D bar code symbologies, RFID (3.1.13) and limited memory-capacity ICs (PICs and ICs with contacts)

Note 1 to entry: Compact encoding generates one constructed data object containing all data groups (3.1.9) . Selective reading is not possible and the read device reads all data at the same time ここで, after the data is parsed. Using this method for machine-readable technologies with large memory capacity is not recommended as it can result in prolonged reading time.

Note 2 to entry: Compact encoding may also be used where the total memory capacity exceeds 5 kB (e.g. ICs with contacts and PICs) but where the capacity available to the IDL application is limited due to capacity being reserved for other applications.

3.1.9

data group

DG

collection of related data elements

3.1.10

delimiter

D

character used to separate data elements in a machine-readable data stream

3.1.10.1

data group delimiter

multiplication sign"×"

Note 1 to entry: Character D7 of ISO/IEC 8859-1.

3.1.10.2

field delimiter

division sign"÷"

Note 1 to entry: Character F7 of ISO/IEC 8859-1.

3.1.10.3

sub-field delimiter

sub-delimiter

semicolon “;”

Note 1 to entry: Character 3B of ISO/IEC 8859-1.

3.1.10.4

end of file delimiter

pilcrow “¶”

Note 1 to entry: Character B6 of ISO/IEC 8859-1.

3.1.11

digital signature

data appended to, or cryptographic transformation of, a data string that proves the origin and the integrity of the data string and protects against forgery, e.g. by the recipient of the data string

3.1.12

standard encoding

encoding method when the memory capacity available for the IDL application exceeds 5 kB, typically applicable to ICs (PICs and ICs with contacts)

3.1.13

radio-frequency identification

RFID

ISO/IEC 14443-compliant IC designed primarily for data storage
