11、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 established by the respective organization to deal with particular fields of t
12、echnical 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 field of information technology, ISO and IEC have established a joint te
13、chnical 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 International Standards adopted by the joint technical committee are
14、 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 document may be the subject of patent rights. ISO and IEC shall not be
15、 held responsible for identifying any or all such patent rights. ISO/IEC 19784-2 was prepared by Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 37, Biometrics. ISO/IEC 19784 consists of the following parts, under the general title Information technology Biometric applicat
16、ion programming interface: Part 1: BioAPI specification Part 2: Biometric archive function provider interface BS ISO/IEC 19784-2:2007 ISO/IEC 19784-2:2007 (E)vIntroduction This part of ISO/IEC 19784 specifies the interface to an archive BFP. An archive BFP is responsible for the storage and manageme
17、nt of BIRs. The archive BFP interface covers functions to attach, detach and operate related functional units by the biometric service provider, to store BIRs, to retrieve information about stored BIRs and to retrieve formerly stored BIRs for further processing by a BSP. ISO/IEC 19784-1 provides a h
18、igh-level generic biometric authentication model. This part of ISO/IEC 19784 specifies a BSP archive interface. An archive is responsible for the management of biometric data storage. Because of the application-specific requirements of biometric data storage, an archive interface is standardized. Th
19、e BioAPI Unit where the BIRs are stored is completely under control of the archive BFP. The general model for the handling of BIRs is as if they were data records in a database. BS ISO/IEC 19784-2:2007 ISO/IEC 19784-2:2007 (E) blank BS ISO/IEC 19784-2:2007 ISO/IEC 19784-2:2007 (E)11 Scope This part
20、of ISO/IEC 19784 specifies the interface to an archive biometric function provider. NOTE The interface assumes that the archive will be handled as a database, regardless of its physical realization. (Smartcards, tokens, memory sticks, files on hard drives and any other kind of memory can be handled
21、via an abstraction layer presenting a database interface.) This part of ISO/IEC 19784 enables any third party to create biometric archive function providers, which may be plugged into any biometric service provider supporting this interface. It is not in the scope of this part of ISO/IEC 19784 to de
22、fine security and privacy requirements for storage and management of BIRs. 2 Conformance A conformant BAFP is required to support all functions and parameters specified in this part of ISO/IEC 19784. No subsets of conformant BAFP functions are defined. NOTE BSPs may require any of those functions an
23、d parameters. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. NOTE Function names and data element names are not included here, but are defined within the body of this part of ISO/IEC 19784. 3.1 biometric archive function provider BAFP BioAPI com

25、fies the interface at the top of the BioAPI Framework, which a biometric application uses to interact with BSPs, and through that to biometric units either directly or through BFPs (see Figure 1 and Figure 2 of ISO/IEC 19784-1:2006).

BS ISO/IEC 19784-2:2007 ISO/IEC 19784-2:2007 (E) 35 BAFPI Definition 5.1 BAFPI data structures 5.1.1 BioAFPI_EventHandler This defines the event handler interface to receive asynchronous notification of events of type BioAPI_ EVENT fro
38、m a BioAPI Unit. Example events include insertion or removal of a BioAPI Unit (e.g. insertion or withdrawal of a Smartcard storing biometric templates for off card or on card matching). This event handler is passed to the BAFP during BioAFPI_BFPLoad. This is the single event handler that all BioAPI
39、Units managed by this BAFP should use to notify the BSP of event types that occur in a loaded BAFP. typedef BioAPI_RETURN (BioAPI *BioAFPI_EventHandler) (const BioAPI_UUID *BAFPUuid, BioAPI_UNIT_ID UnitID, BioAPI_UNIT_SCHEMA *UnitSchema, BioAPI_ EVENT EventType); BAFPUuid (input) The UUID of the BAF
40、P raising the event. UnitID (input) The unit ID of the BioAPI Unit (biometric archive) associated with the event. UnitSchema (input) The schema of the BioAPI Unit raising the event. EventType (input) The BioAPI_ EVENT that has occurred. 5.1.2 BioAFPI_BAFPPropertyID Defines the UUID of the format of
41、the BioAFPI_BAFPPropertySchema. When a BAFP claims to be conformant to this part of ISO/IEC 19784, it has to use a PropertySchema as defined within this part of ISO/IEC 19784. #define (BioAFPI_BAFPPropertyID, 0x561403e5, 0x7d2d, 0x489a, 0x89, 0x41, 0xe7, 0xa9, 0x35, 0x99, 0xcf, 0x9c); BS ISO/IEC 197
42、84-2:2007 ISO/IEC 19784-2:2007 (E)4 5.1.3 BioAFPI_BAFPPropertySchema The BioAFPI_BAFPPropertySchema contains information about the function providers capabilities, which are presented to the BioAPI component registry and in the related function calls. The function provider capabilities can differ fr
43、om the capabilities of a biometric archive unit. The capabilities usuable by a BSP or BioAPI application are the intersection of the BAFP and biometric archive unit capabilities. typedef struct _bioafpi_bafp_property_schema uint32_t MaxRecordLength; uint32_t MaxRecordNumber; uint32_t MaxDatabases; u
44、int32_t MaxResponseTime; BioAPI_POWER_MODE SupportedPowerModes; BioAFPI_BAFP_PROPERTY_SCHEMA, *BioAFPI_BAFP_PROPERTY_SCHEMA_PTR; MaxRecordLength The value defines the maximum length in bytes of a record. A record presents a BIR. A Biometric Unit shall use a value smaller or equal to this value in it
45、s UnitSchema. A 0 means that no information about the maximum record length is given. MaxRecordNumber The value defines the maximum number of records. A Biometric Unit shall use a value smaller or equal to this value in its UnitSchema. A 0 means that no information about the maximum number of record
46、s is given. MaxDatabases The value defines the maximum number of databases, which can be managed by the AFP at a time. A 0 means that no information about the maximum number of databases is given. MaxResponseTime The value defines the maximum time in milliseconds a caller of any BAFP function has to
47、 wait until the function returns. A Biometric Unit shall use a value smaller or equal to this value in its UnitSchema. A 0 means that no information about the maximum time until the BioAPI Unit returns is given. SupportedPowerModes The bit mask defining, which power modes can be handled by the BFP.
48、Handling of a power mode means to pass the related function call to the BioAPI Unit, when this supports the mode and to return the error code related to the result of the reaction of the BioAPI Unit. 5.1.4 BioAFPI_UnitPropertyID Defines the UUID of the format of the BioAFPI_UnitPropertySchema. When
49、a BAFP claims to be conformant to this part of ISO/IEC 19784, it has to use a PropertySchema as defined within this part of ISO/IEC 19784. #define (BioAFPI_UnitPropertyID, 0x94cae58f, 0x6b26, 0x41fc, 0x9d, 0xdb, 0xd9, 0x8e, 0x9a, 0xd5, 0x6f, 0xa0); BS ISO/IEC 19784-2:2007 ISO/IEC 19784-2:2007 (E)4 5.1.3 BioAFPI_BAFPPropertySchema The BioAFPI_BAFPProperty
