S
30、cope This standard specifies requirements for the use of ISO/IEC 19784-1, BioAPI Specification (also known as BioAPI 2.0), a software interface standard, for the purpose of performing a tenprint capture operation. This includes one or more of the following: 1. Identification of BioAPI functions to b
31、e utilized and the order (if any) in which they are to be called 2. Specification of values for function parameters 3. Definition of GUI (graphical user interface) events (for use with an application controlled GUI) 4. User interface specifications for use with a BSP (biometric service provider) con
32、trolled GUI 5. Sample calling sequences and example inputs/outputs 2. Conformance Biometric Service Providers (BSPs) that claim conformance to this standard shall satisfy the normative requirements as described in Clauses 5 through 9. 3. Normative References The following standards contain provision
33、s which, through reference in this text, constitute provisions of this American National Standard. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the stand
34、ards indicated below. 1. ANSI/NIST-ITL 1-2007, Data Format for the Interchange of Fingerprint, Facial, 6.1.3 Parameters 6.1.3.1 BSPHandle (input) The handle of the attached BSP. 6.1.3.2 UnitID (input) ID of the BioAPI Unit. 6.1.3.3 ControlCode (input) Indicates the purpose of this function to differ
35、entiate it from other BioAPI_ControlUnit() calls. The value of “1” shall be used to indicate that a CCB is being set. 6.1.3.4 InputData (input) Pointer to a BioAPI_Data structure. This structure shall contain the address and length of the CCB. 3 ANSI INCITS 434-2007 6.1.3.5 OutputData (output) No ou
36、tput is needed. The buffer address will be NULL and length set to “0” within the BioAPI_DATA structure. Usage of the OutputData parameter to return diagnostic data about the CCB should be considered. 6.1.4 Additional Error Return Codes Error codes should be used to indicate errors detected in the CC
37、B passed in the InputData parameter. See Clause 10. 6.2 BioAPI_Capture() 6.2.1 Usage This function shall trigger a BSP to perform fingerprint image captures and to create a new CCB. The fingers captured and the processing done on the fingers shall be controlled by inclusion of empty fields in the cu
38、rrent CCB, which was specified in the BioAPI_ControlUnit() call. 6.2.2 Prototype BioAPI_RETURN BioAPI BioAPI_Capture (BioAPI_HANDLE BSPHandle, BioAPI_BIR_PURPOSE Purpose, BioAPI_BIR_SUBTYPE Subtype, BioAPI_BIR_BIOMETRIC_DATA_FORMAT *OutputFormat, BioAPI_BIR_HANDLE *CapturedBIR, Int32_t Timeout, BioA
39、PI_BIR_HANDLE *AuditData); 6.2.3 Parameters 6.2.3.1 BSPHandle (input) The handle of the attached BSP. 6.2.3.2 Purpose (input) A value indicating the purpose of the biometric data capture. For the purposes of tenprint capture, the value BioAPI_PURPOSE_ENROLL shall be used. 6.2.3.3 Subtype (input/opti
40、onal) Specifies which subtype to capture. This parameter does not have the flexibility to describe the range of possible finger image sets that might be captured. A value of BioAPI_NO_SUBTYPE_AVAILABLE (0x00) shall be used to indicate that the BSP is to select the subtypes using the current CCB. 6.2
41、.3.4 OutputFormat (input/optional) Specifies which BDB (biometric data block) format to use for the returned CapturedBIR. Format Owner and Format Type shall be set to 0x001B and 0x8013 respectively to designate that the 4 ANSI INCITS 434-2007 BIR (biometric information record) shall consist of a COB
42、. Alternatively a NULL pointer shall be used to indicate that output format selection will be handled by the BSP. 6.2.3.5 CapturedBIR (output) A handle to a BIR containing captured data, the COB. See Clause 9 for a specification of this BIR. 6.2.3.6 Timeout (input) Specifies the timeout value (in mi
43、lliseconds) for the capture operation. If this timeout is reached, the function returns an error, and no results. This value can be any positive number. A -1 value means the BSPs default timeout value will be used. 6.2.3.7AuditData (output/optional) A handle value of BioAPI_UNSUPPORTED_BIR_HANDLE sh
44、all be used to indicate that AuditData is not available. 6.2.4 Additional Error Return Codes BioAPI includes codes such as BioAPIERR_UNABLE_TO_CAPTURE to indicate that the BSP could not collect the data that it is meant to. Additional error codes specific to tenprint capture are specified in Clause
45、10. 6.3 BioAPI_QueryUnits() 6.3.1 Usage Applications will use this function to determine if the device attached to the BSP conforms to this standard and if so, to discover what specific capabilities are supported by the attached tenprint capture device (unit). 6.3.2 Prototype BioAPI_RETURN BioAPI Bi
46、oAPI_QueryUnits (const BioAPI_UUID *BSPUuid, BioAPI_UNIT_SCHEMA *UnitSchemaArray, uint32_t *NumberOfElements); 6.3.3 Parameters 6.3.3.1 BSPUuid (input) The unique identifier for the (tenprint) BSP to which the unit (tenprint scanning device) is attached and for which the unit information is to be re
47、turned. 6.3.3.2 UnitSchemaArray (output) A pointer to the address of the array of elements of type BioAPI_UNIT_SCHEMA containing the unit schema information. Specific elements of interest are defined in 6.3.4, below. 5 ANSI INCITS 434-2007 6.3.3.3 NumberOfElements (output) A pointer to the number of
48、 elements in the array. 6.3.4 BioAPI_UNIT_SCHEMA This schema is defined in Clause 7.55 of the base standard (BioAPI specification). There are three elements of this structure that are of particular interest for the purpose of tenprint capture (the UnitProperties, UnitPropertyID, and UnitProperty ele
49、ments), though other elements of the schema may also be of general use (e.g., vendor information, firmware version, etc.). If more than one type of BioAPI Unit is attached to the BSP, more than one Unit schema may be returned. Tenprint scanner devices shall set UnitCategory to BioAPI_CATEGORY_SENSOR (0x00000008). 6.3.4.1 UnitProperties UUID indicating a set of properties of the BioAPI Unit. The indicated set can either be specified by each vendor or follow a related standard. The UUID “ba38567f-66be-468c-9
