19、terchange 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 conducting conformance tests ofcommercial products tha

20、t 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 INCITS 377-2004 may differ and not inter-operate

21、. 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 can be considered to be in conformance withANS

22、I 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 377-2004 by producing conformant templates. A proce

23、ss 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 Finger Pattern Data Record requirements as setfort

24、h 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 conformance test suites and re-lated test metho

25、ds 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 of standards is applicable to the develop-men

26、t 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 primarily for use by testing organizations, but ma

27、y 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 InformationTechnology Standards (INCITS), ITI, 110

33、 (Alt.)National Institute of Standards this flow shall be repeated for every finger pattern record in the data file. Start Open/parse the data file containing fingerprint pattern in accordance with ANSI INCITS 377-2004 Level 1 testing: Verify value of each field and the ranges of the values in those

34、 fields Level 2 testing: Verify values of those specified fields are internally consistent. Output test report Figure 1 ANSI INCITS 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, nonconformanc

35、e of the IUT shall be proven), but the absence of errors does not necessarily imply the converse. This test method is intended 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

36、 be required, which is impractical for both technical and economic reasons. 6.3.2 Test Method Implementation Requirements A test 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

37、of the test suite, describing test categories, test objectives for each individual test, instructions on how to execute the test 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 t

38、he results, and reporting them in a human-readable form. b) Documented test cases that shall sufficiently assure conformity to 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,

39、which can be submitted to the CTS for subsequent execution. c) A Conformance Testing Procedure, which shall identify and define 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

40、 testing of a given IUT can be repeated with no significant changes in test results. The procedure shall also identify necessary administrative processes that may include record keeping, personnel, security, and other requirements. A test method implementation shall use the required assertion defini

41、tions, types, syntax, and constructs specified in this standard as applicable. Also, it shall use test result codes specified in this standard.

42、e from IHS-,-,-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 conformance t

43、esting 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 the

44、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 all

45、 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 correctl

46、y 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 to

47、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 created

48、 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 software 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).
