    Abstract: PROBLEM TO BE SOLVED: To provide a new authenticating process for mounting a conversation type system having elaborate dialog so as to provide the continuous and moderate authentication of a user during a process wherein the user converses with the conversation type system. SOLUTION: The system and method provide continuous reliability-based authentication. This system can be mounted on an increment access authentication system for controlling access to protected data having various security levels. In the process of a conversation type session between the user and a machine, this reliability-based authentication system periodically analyzes the input speech of the user who converses with the system so as to compute a 'reliability index' regarding the adequacy of a source discrimination request (i) that the user provides at the start of a dialog session. The computing process for the 'reliability index' is seamlessly integrated with the increment authentication system so as to adjust the dialog between the increment access authentication system and the user according to the reliability of the user of the source discrimination request.

    Abstract: A system and method for verifying user identity, in accordance with the present invention, includes a conversational system (114) for receiving inputs from a user (110) and transforming the inputs into formal commands. A behavior verifier (118) is coupled to the conversational system (114) for extracting features from the inputs. The features include behavior patterns of the user. The behavior verifier (118) is adapted to compare the input behavior to a behavior model (214) to determine if the user is authorized to interact with the system.

    Abstract translation: 根据本发明的用于验证用户身份的系统和方法包括用于从用户（110）接收输入并将输入转换为正式命令的对话系统（114）。 行为验证器（118）耦合到对话系统（114），用于从输入中提取特征。 功能包括用户的行为模式。 行为验证器（118）适于将输入行为与行为模型（214）进行比较，以确定用户是否被授权与系统交互。
