These technologies are also expected to be applied to open network systems for reliable user authentication. However, open network systems need to manage risks in biometric products and system c

Source Recommendation ITU-T X.1084 was approved on 29 May 2008 by ITU-T Study Group 17 (2005-2008) under Recommendation ITU-
9、T A.8 procedures. Keywords Telebiometric authentication profiles, telebiometric authentication protocol, telebiometric system mechanism, transport layer security. ii Rec. ITU-T X.1084 (05/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the f
10、ield of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standard
11、izing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is cover
12、ed by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indica
13、te both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved
14、when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROP
15、ERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether assert
16、ed by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

25、T X.1084 (05/2008) v Introduction With the rapid and widespread diffusion of the Internet, various network services are now in operation. In high value services, such as Internet banking, Internet shopping, Internet trading, etc., illegal trading by obtaining a personal identification number (PIN) b
26、y means, such as phishing, are occurring with increasing regularity. Therefore, high security authentication mechanisms are increasingly required, such as can be provided by biometrics. We have the following problems in standardizing biometric authentication on the Internet: Service providers do NOT
27、 have any information regarding what biometric devices are in use at the end-users end, what security level is this device set at, or how it is operated. According to each biometric product, the accuracy (False Accept Rate) determined by the threshold parameter differs between different biometric pr
28、oducts. Therefore, the service provider can NOT claim to maintain a uniform accuracy level. The accuracy of biometric verification may decline with the aging of end-users because biometrics uses features of the human body. To solve these problems, protocols for biometric authentication between unspe
29、cified end-users and service providers on open networks are greatly required. The figure below illustrates the environment of this Recommendation for a biometric security mechanism that authenticates a user via a non-face-to-face open network.

30、iometric SensorEnd UserEnvironment of this Recommendation The meaning of the open network: Many unspecified verifiers connect to the network and use varying biometric methods. High value service provider Efficient government service provider Online shopping provider. A large number of unspecified en
31、d-users also connect to the network, and their identity is verified through biometric authentication in order to use services from the aforementioned providers. The verifier here is “open“ in the following sense. The purpose of biometric authentication is different for each verifier, and the risk/va
32、lue for the verifier is also different for each. Therefore, each verifier has a different authentication security policy. The user here is “open“ in the sense that each user uses different biometric authentication methods. Each user can select any biometric authentication method to use, according to
33、 the acceptability or privacy policy they follow. Rec. ITU-T X.1084 (05/2008) 1 Recommendation ITU-T X.1084 Telebiometrics system mechanism Part 1: General biometric authentication protocol and system model profiles for telecommunications systems 1 Scope This Recommendation specifies the biometric a
34、uthentication protocols and profiles for telecommunication systems. It defines the protocols for biometric authentication of unspecified end-users and service providers on open networks. In the open network, there are a range of biometric communication devices for the end-users. There are also a var
35、iety of security policies for network services for the providers. This Recommendation defines nine telebiometrics authentication models depending on the configuration of the client, the server, and the trusted third party. It also defines the negotiation protocol for the policies and the device envi
36、ronments using the models. Furthermore, it specifies the requirements of biometric transportation data for each model. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
