There is disclosed a technique for use in authentication. The technique comprises receiving an authentication request. The technique also comprises evaluating an attribute associated with the implementation of the authentication request. The attribute is evaluated with respect to at least one available authentication method. The technique also comprises selecting an available authentication method suitable for use in authentication based on the said evaluation.

Authentication systems with selective authentication method

A method is used in managing knowledge-based authentication systems. A set of factors is evaluated for gathering organization based information from a set of information sources for authenticating a user in a knowledge-based authentication system. The organization based information is collected based on the evaluation.

Managing knowledge-based authentication systems

An improved technique involves generating KBA questions from facts obtained from a personal information management (PIM) server under the control of an organization. Along these lines, such an organization acquires facts from documents such as emails, meeting notices, presentations, and spreadsheets that are stored on a PIM server such as a Microsoft&#xae; Exchange server or IBM Lotus&#xae; Domino server. A KBA server then generates KBA questions from the acquired facts and stores the KBA questions on a question server. In some arrangements, the KBA server filters out KBA questions based on the nature of the facts from which the KBA questions were derived. The remaining KBA questions are ranked based on historical question data; the KBA server provides the most highly ranked KBA questions to a user claiming to be a member of the organization.

Question generation in knowledge-based authentication for an enterprise

A method is used in managing knowledge-based authentication systems. Organization based information is analyzed for information that is suitable for creating a set of responses for a question. The question is used for authenticating a user. A set of responses is created for the question based on a set of parameters. The set of responses includes incorrect responses to the question along with a correct response. The incorrect responses helps in identifying an unauthorized user.
