16、INCITS 423.3-2009.)The Finger Pattern Data Interchange Format, ANSI INCITS 377-2004, provides anindustry standard to allow for fingerprint pattern data extracted with one vendors al-gorithm to be useful to another vendors matching algorithm. Currently, there are no standardized methods for conductin
17、g conformance tests ofcommercial products that claim to support the Finger Pattern Data Interchange For-mat, ANSI INCITS 377-2004. Application and Biometric Service Provider (BSP) de-velopers may interpret ANSI INCITS 377-2004 differently from one another;therefore, their implementations of ANSI INC
18、ITS 377-2004 may differ and not inter-operate. There is a need for a standardized, generally accepted, Finger Pattern DataInterchange Format conformance testing methodology that would allow implementa-tion of a set of test tools realizing this methodology. A particular fingerprint pattern template c
19、an be considered to be in conformance withANSI INCITS 377-2004. In this case, a template can be parsed and examined to as-sure that the data layout is consistent with ANSI INCITS 377-2004. A process thattransforms fingerprint images into fingerprint pattern templates can conform to ANSIINCITS 377-20
20、04 by producing conformant templates. A process that assesses thesimilarity of fingerprints can conform to ANSI INCITS 377-2004 by accepting a con-formant pattern template as input.ANSI INCITS 423.3 defines a testing methodology to assure conformance of a ven-dors application or service to the Finge
21、r Pattern Data Record requirements as setforth in ANSI INCITS 377-2004. It intends to:a) Establish elements of the Conformance Testing Methodology framework that arespecific to the Finger Pattern Data Record requirements of ANSI INCITS 377-2004.b) Define requirements and guidelines for specifying co
22、nformance test suites and re-lated test methods for measuring conformity of products and services to the Fin-ger Pattern Data Record requirements of ANSI INCITS 377-2004, andc) Define test procedures to be followed before, during, and after conformancetesting.This part of the ANSI INCITS 423 series
23、of standards is applicable to the develop-ment and use of conformity test method specifications, conformity test suites for Fin-ger Pattern Data Record requirements as specified in ANSI INCITS 377-2004, andconformance testing programs for ANSI INCITS 377-2004-conformant products. It isintended prima
24、rily for use by testing organizations, but may be applied by developersand users of test method specifications and test method implementations.Requests for interpretation, suggestions for improvement or addenda, or defect re-ports are welcome. They should be sent to InterNational Committee for Infor

31、NCITS 377-2004 BDR File Format Level 1 and Level 2 Conformance Test Flow This testing methodology can only demonstrate nonconformity (i.e., if errors are found, nonconformance of the IUT shall be proven), but the absence of errors does not necessarily imply the converse. This test method is intended
32、 to provide a reasonable level of confidence and practical assurance that the IUT conforms to the base standard. To guarantee such conformity, a very exhaustive testing would be required, which is impractical for both technical and economic reasons. 6.3.2 Test Method Implementation Requirements A te
33、st method implementation shall document that it conforms to this standard by including the following: a) A CTS conformant to ANSI INCITS 377-2004 that includes documentation of the test suite, describing test categories, test objectives for each individual test, instructions on how to execute the te
34、st suite, and the expected results of executing the individual tests. The CTS shall be capable of executing the test script sets, capturing the returned results, evaluating the results, and reporting them in a human-readable form. b) Documented test cases that shall sufficiently assure conformity to
35、 the requirements as specified in the base standard. The test cases shall be formally represented in the form of test assertions, preferably using a test assertion language, which can be submitted to the CTS for subsequent execution. c) A Conformance Testing Procedure, which shall identify and defin
36、e all the activities necessary to prepare for conformance testing, perform the conformance testing and report the test results. The procedure shall be detailed enough so that testing of a given IUT can be repeated with no significant changes in test results. The procedure shall also identify necessa
37、ry administrative processes that may include record keeping, personnel, security, and other requirements. A test method implementation shall use the required assertion definitions, types, syntax, and constructs specified in this standard as applicable. Also, it shall use test result codes specified
38、in this standard. INCITS 423.3-2009 9 6.3.3 Conformance Testing Process The conformance testing process is the complete process of accomplishing of all conformance testing activities necessary to assess the conformity of an IUT to the requirements as specified in ANSI INCITS 377-2004. The conformanc
39、e testing process involves three phases: 1) Preparation for testing, which includes the collection of the necessary information that is related to the submitted finger pattern records that needs to be included in the test report. 2) Test execution, which includes execution of the CTS and recording t
40、he observed test results in conformity test log(s). The results of conformance testing shall apply only to the IUT and the test environment for which the tests are run. 3) Test report production, which includes the recording of all events that occur during the execution of each test case, including
41、all test outcomes and test verdicts. To achieve the objective of credible conformance testing, the result of executing a test case on an IUT should be the same whenever it is performed. It may be necessary to review the observed test outcomes in order to make sure that all procedures have been corre
42、ctly followed. It is essential that all inputs, outputs, and other test events be logged for each test case being executed with sufficient information to produce a conformity log for each test execution for future reference. 6.4 Test Procedures 6.4.1 General A software product can claim conformance
43、to requirements as specified in ANSI INCITS 377-2004 and document this claim in the FCS as described in 6.1.3. Conformance of a software product with respect to the ability to produce finger pattern data records shall be verified by testing the conformance of a reasonable number of data records crea
44、ted by the product. Please refer to 6.1 of ANSI INCITS 423.1-2008. The product shall be determined to be conformant to the requirements as specified in ANSI INCITS 377-2004 if and only if all those data records (tested using the test assertions specified in Clause 7) have passed the tests. Most soft
45、ware products that process finger pattern data records will emit some form of error message when they detect an invalid input (for example, an error message may be directed to a user through the user interface or may be written to a log file). Conformance testing of software products that process da
46、ta records can only be performed if the product emits error messages that are observable by a testing operator. Every file that conforms to ANSI INCITS 377-2004 must be able to be fully parsed or partially parsed by the CTS. Failure to meet ANSI INCITS 377-2004 for a single test input file results i
47、n the test case failing to be conformant for the test. The test procedures are based on the three-levels testing specification described in ANSI INCITS 423.1-2008. 6.4.2 ANSI INCITS 377-2004 Level 1 and 2 Conformant Testing Procedure Flow Chart Figure 2 shows the detailed flow of the BDIR data file
48、conformance testing implementation procedure. The flow chart in figure 2 starts with parsing of the finger image-based BDIRs and then proceeds to evaluate the values in each data field. In this figure, finger image-based BDIR indicates the dataset file containing data records under test. 6.4.3 Test
49、Execution The execution of the conformance test shall include execution of a Conformance Test Suite (CTS) capable of processing the test cases (test assertions) specified in clause 7. The test execution shall include automated and/or manual testing INCITS 423.3-2009 10 procedures implementing individual test cases, and recording the observed test results in conformity test log(s). The results of conformance testing shall apply only to IUT and the test environment for which the tests a
