National bodies that are members of ISO or IE
29、C 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 international organizations, gove
30、rnmental 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 in the ISO/IEC Directives, P
31、art 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 at least 75 % of the nationa
32、l 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. ISO/IEC 19784-1 was prepared by Joint Technical Committee ISO/IEC JT
33、C 1, Information technology, Subcommittee SC 37, Biometrics. ISO/IEC 19784 consists of the following parts, under the general title Information technology Biometric application programming interface: Part 1: BioAPI specification Part 2: Biometric archive function provider interface This is the first
34、 ISO/IEC standard on BioAPI. Previous versions were published by ANSI and the BioAPI Consortium. As the last official non-ISO release was designated Version 1.1, this ISO/IEC 19784-1 version is designated Version 2.0. This is to distinguish the versions of BioAPI products in the marketplace.

36、ides a high-level generic biometric authentication model suited to most forms of biometric technology. No explicit support for multimodal biometrics is currently provided. An architectural model is described which enables components of a biometric system to be provided by different vendors, and to i
37、nterwork through fully-defined Application Programming Interfaces (APIs). A key feature of the architecture is the BioAPI Framework, which supports calls by one or more application components (provided by different vendors, and potentially running concurrently) using the BioAPI API specification. Th
38、e BioAPI Framework provides this support by invoking (through a Service Provider Interface, SPI) one or more biometric service provider (BSP) components (provided by different vendors, and potentially running concurrently) which can be dynamically loaded and invoked as required by an application com
39、ponent. At the lowest level there is hardware or software that performs biometric functions such as capture, matching, or archiving. These parts of the architecture are called BioAPI Units, and can be integral to a BSP or can be supplied as part of a separate BioAPI Function Provider (BFP) component
40、. Interactions (through the BioAPI Framework) can occur between BSPs from different vendors provided data structures used to record information from the BioAPI Units they access conform to other International Standards, and in particular to ISO/IEC 19794 5. The final component of the BioAPI architec
41、ture is the recognition that a BSP can provide its biometric services either: a) by the use of BioAPI Units that are integral to (that is, directly managed by) the BSP, or b) by invoking, through the BioAPI Function Provider Interface (FPI), one or more BFP components (provided by different vendors)
42、 that manage BioAPI Units that are integral to the BFP. NOTE: A BioAPI Unit may consist of software only, or a combination of software and hardware (e.g., a biometric sensor, archive, or algorithm). For each type of BioAPI Unit supported by a BSP (or BFP) there may be one or more BioAPI Units of tha
43、t type which can be dynamically inserted and removed from the system. Insertion and removal generates events that can be signalled (through the BSP and the BioAPI Framework) to an application. The BioAPI specification covers the basic biometric functions of Enrollment, Verification, and Identificati
44、on (see Annex C), and includes a database interface to allow an application to manage the storage of biometric records through an archive BioAPI Unit managed by a BSP or BFP. This provides for optimum performance (e.g., when performing the biometric Identification function within a large population)
45、 of the archiving and biometric search processes. The interface to the application provides primitives that allow it to manage the capture of biometric samples from a biometric sensor by accessing the corresponding BioAPI Unit, and the use of those biometric samples for Enrollment (storage in an app
46、lication-controlled or BSP-controlled BIR database), and subsequent Verification or Identification against those stored records. This part of ISO/IEC 19784 also specifies the content of a biometric component registry (information about the biometric components that have been installed on the biometr
47、ic system). It also provides a component registry interface for the management and inspection of that registry. This part of ISO/IEC 19784 uses the C programming language (see ISO/IEC 9899) to specify the data structures and function calls that form the BioAPI interfaces. Copyright American National
