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 INCITS/ISO/IEC 19784-2-20072008 ITIC 2008 - All rights

17、 reservedvIntroduction This part of ISO/IEC 19784 specifies the interface to an archive BFP. An archive BFP is responsible for the storage and management of BIRs. The archive BFP interface covers functions to attach, detach and operate related functional units by the biometric service provider, to s

18、tore 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 high-level generic biometric authentication model. This part of ISO/IEC 19784 specifies a BSP archive interface. An archive is responsible for the man

19、agement of biometric data storage. Because of the application-specific requirements of biometric data storage, an archive interface is standardized. The 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

20、 data records in a database.

NOTE The inter

21、face 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 via an abstraction layer presenting a database interface.) This part of ISO/IEC 19784 enables any

22、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 define security and privacy requirements for storage and management of BIRs. 2 Conformance A conform

23、ant 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 and parameters. 3 Terms and definitions For the purposes of this document, the following terms and d

24、efinitions 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 component, attached to a BSP via its interface, for storage, management and interchange of BIRs 3.2 b

25、iometric archive function provider interface BAFPI BAFP-to-BSP interface which supports the functions to manage the BAFP itself, its databases or BIRs 4 Interface architecture ISO/IEC 19784-1:2006 specifies the interface at the top of the BioAPI Framework, which a biometric application uses to inter

26、act 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). Information technology Biometric application programming interface Part 2: Biometric archive function provider interface 2 The BAFPI contains the following types of

27、 functions. General BFP management functions, which are called by the BSP to manage the BFP and its associated BioAPI Units. These functions are not directly related to SPI functions: BioAFPI_BAFPLoad; BioAFPI_BAFPUnload; BioAFPI_UnitAttach; BioAFPI_UnitDetach; BioAFPI_QueryUnits; BioAFPI_Free (the

28、relation of this function to the respective SPI call depends on the behaviour of the BSP when the BSP copies the data the BFP has allocated memory for then it can immediately send BioAFPI_Free to the BFP, otherwise the BSP will call this function when itself is requested to free the memory for these

29、 data). Unit management functions: BioAFPI_ControlUnit (this function is directly related to the SPI function); BioAFPI_Cancel (this function can be called in relation to the respective calls of the SPI or the application, but can be called for other reasons from the BSP also when there is no respec

30、tive request from the BioAPI framework or application; BioAFPI_SetPowerMode (this function is directly related to the SPI function). Database management functions. These functions are directly related to the respective functions of the SPI: BioAFPI_DbOpen; BioAFPI_DbClose; BioAFPI_DbCreate; BioAFPI_

31、DbDelete. Record management functions. These functions are directly related to the respective functions of the SPI: BioAFPI_DbSetMarker; BioAFPI_DbFreeMarker. Data management functions. These functions are directly related to the respective functions of the SPI: BioAFPI_DbStoreBIR; BioAFPI_DbGetBIR;

32、 BioAFPI_DbGetNextBIR; BioAFPI_DbQueryBIR; BioAFPI_DbDeleteBIR.

33、PI_ EVENT from 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 tha

34、t all BioAPI 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 UU

35、ID of the BAFP 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 t

36、he format of 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); I

A record presents a BIR. A Biometric Unit shall use a value smaller

40、or equal to this value in its 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

41、the maximum number of records 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

42、 of any BAFP function has to 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

43、 can be handled by the BFP. 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 BioAF

44、PI_UnitPropertySchema. 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_UnitPropertyID, 0x94cae58f, 0x6b26, 0x41fc, 0x9d, 0xdb, 0xd9, 0x8e, 0x9a, 0xd5, 0x6f, 0xa0); INCITS/ISO/IEC 19784-2-
