3、ed October 13, 2009American National Standards Institute, Inc.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of

4、the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effo

Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the name of

22、echnology Standards) is theAmerican National Standards Insti-tute (ANSI) recognized standards developmentorganization for information technology within the United States of America. Mem-bers of INCITS are drawn from Government, Corporations, Academia and other or-ganizations with a material interest

23、 in the work of INCITS and its TechnicalCommittees. INCITS does not restrict membership and at-tracts participants in itstechnical work from 13 different countries, and operates under the rules of the ANSI.In the field of Biometrics, INCITS has established the Technical Committee M1. Stan-dards deve

24、loped by this Techni-cal Committee have reached consensus throughoutthe development process and have been thoroughly reviewed through several PublicReview processes. In addition, the INCITS Executive Board and ANSI Board of Stan-dards Review have approved this American National Standard for Publicat

31、implementations of the specification may dif-fer and not interoperate.Conformance to ANSI INCITS 381-2004 is a necessary prerequisite for achieving in-teroperability among implementations; therefore, there is a need for a standardized,generally accepted, Finger Image-based Data Interchange Format co

32、n-formancetesting methodology that would allow implementation of a set of test tools realizingthis methodology.This part of ANSI INCITS 423 is intended for those applications that require use offinger image data according to ANSI INCITS 381-2004. It defines a testing methodol-ogy to assure conforman

33、ce of a vendors application or service to the Finger Image-based Data Record requirements as set forth in ANSI INCITS 381-2004. This part ofANSI INCITS 423 is intended to:a) establish elements of the Conformance Testing Methodology framework thatare specific to the Finger Image-based Data Record req

34、uirements of ANSIINCITS 381-2004 conformance testingb) define requirements and guidelines for specifying conformance test suitesand related test methods for measuring conformity of products and servicesto the Finger Image-based Data Record requirements of ANSI INCITS 381-2004, andc) define test proc

35、edures to be followed before, during, and after conformancetesting.This part of ANSI INCITS 423 is applicable to the development and use of conformitytest method specifications, conformity test suites for Finger Image-based DataRecord requirements as specified in ANSI INCITS 381-2004, and conformanc

37、 for Information Technology Conformance Testing Methodology Standard for Biometric Data Interchange Format Standards Part 4: Conformance Testing Methodology for INCITS 381-2004, Finger Image-Based Data Interchange Format 1 1 Scope This part of ANSI INCITS 423 is concerned with conformance testing of

38、 implementations claiming conformance to the Finger Image-Based Data Interchange Format specification as per ANSI INCITS 381-2004. Further, this part of ANSI INCITS 423 is concerned with testing only of the Biometric Data Interchange Records (BDIR) requirements as defined in ANSI INCITS 381-2004. Fo

39、r the purposes of this part of ANSI INCITS 423, and as also described in Part 1: Gener-alized Conformance Testing Methodology of ANSI INCITS 423, conformance testing of the CBEFF requirements as set forth in ANSI INCITS 381-2004 is not within the scope of this part of ANSI INCITS 423. This part of A

40、NSI INCITS 423 is not concerned with testing of other characteristics of biometric products or other types of testing of biometric products (i.e., acceptance, performance, robustness, security). Any organization contemplating the use of test methods defined in this part of ANSI INCITS 423 should car

41、efully consider the constraints on their ap-plicability. For the purposes of this part of ANSI INCITS 423, of the two types (A and B) and three levels (1, 2, and 3) of confor-mance testing as defined in ANSI INCITS 423.1, only Type A and Levels 1 and 2 are within the scope of this part of ANSI INCIT

42、S 423. Selected test cases and assertions that define Level 3 and Type B conformance test methods and procedures are included in this part of ANSI INCITS 423 as informative materials. Materials identified in this part of ANSI INCITS 423 as guidelines are suggestions or options, as are all examples,

43、notes, and footnotes. 2 Conformance Conformance testing methodology implementations (conformance test suites or CTS) that claim conformance to this part of ANSI INCITS 423 shall satisfy the normative requirements of the methodology for those levels of test they are claiming to perform, as described

44、in Clause 6. Additionally, implementations of Level 1 or Level 2 tests shall use the assertions defined in Clause 7 with the specific assertion details given in the relevant subsequent clauses of this part of ANSI INCITS 423. Implementations of ANSI INCITS 381-2004 shall be able to claim conformance

45、 only to those re-quirements specified in ANSI INCITS 381-2004 that are tested by the test methods specified in this part of ANSI INCITS 423. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this American National Stand

46、ard.
