15、tional Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees establishe
16、d by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the fiel
17、d of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft
18、International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this do
19、cument may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

34、1.19785.0.257.1.10 14.6 Domain of use This clause provides a definition of a patron format that may be of general utility to applications that need to carry one or more BIRs (of either the same or different patron formats) in a single complex BIR structure, with explicit identification of the patron
35、 format(s) being used. This patron format is identical to that specified in clause 12 except for the addition of ten new data elements (capture device owner and identifier, feature extraction algorithm owner and identifier, comparison algorithm owner and identifier, quality algorithm owner and ident
36、ifier, and compression algorithm owner and identifier) and a “fieldPresence“ field that is one byte longer. 14.7 Version identifier This patron format specification has a version identifier of 1. 14.8 CBEFF version This specification conforms to CBEFF version (major 2, minor 0). 14.9 General 14.9.1
37、This patron format supports all the mandatory and optional data elements specified in ISO/IEC 19785-1. It can support either a simple BIR or a complex BIR structure where each intermediate node or leaf of the structure is itself a BIR (called a “child BIR“) and can be represented in any patron forma
38、t. ISO/IEC 19785-3:2007/Amd.1:2010(E) 4 ISO/IEC 2010 All rights reserved14.9.2 The patron format of each child BIR is explicitly identified in its parent by a pair: patron format owner / patron format type, and can be either this patron format (in which case the child BIR may itself have children),
39、or a different patron format (in which case the child BIR is considered a leaf of this patron format although it may be a complex BIR in its own regard). 14.9.3 Most fields in this patron format are optional. The presence of each optional field is encoded as a single bit of a 32-bit field (“fieldPre
40、sence“) at the beginning of the format, which has one bit for each optional field defined in the patron format. The bit value 1 in a given position of that field means that the corresponding field is present in the BIR instance. 14.9.4 All character strings and octet strings are preceded by a length
41、 prefix, which can be one, two, or four octets long, as specified for each field. 14.9.5 All integer values, including lengths, are encoded in big-endian order. 14.9.6 Dates and date intervals are encoded as character strings in a way conforming to ISO 8601. 14.9.7 An instance of a BIR or child BIR
42、contains either a BDB or one or more BIR children, but never contains both. 14.10 Specification An instance of a BIR shall contain the fields specified below, in exactly the same order and with no gaps between the fields.
