National bodies

9、that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other inte

10、rnational organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field 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

11、 in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by

12、 at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 3 to ISO/IEC 19784-1:2006 was

13、 prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 37, Biometrics. This amendment to ISO/IEC 19784-1 defines a new version 2.2 of BioAPI which adds support for biometric fusion and security assertions to ISO/IEC 19784-1. It extends the API and the SPI of Bi

14、oAPI by specifying new functions and new values for existing data types. ISO/IEC 19784-1:2006 provides no direct support for biometric fusion. In addition, the use of FARs in the representation of matching scores is not suitable, in general, for performing score-level fusion (although it does allow

15、some limited forms of fusion). This amendment adds support of biometric fusion to ISO/IEC 19784-1.
