Abstract: In response to changes in security environments, an authentication framework has an important role for service continuity, which can evaluate both of security and usability and handle authentication methods. If the service provider cannot respond to problems such as new attacks immediately, the service must be stopped. In this paper, we propose a multi-factor authentication framework using a probabilistic evaluation method considering service continuity. Our framework includes a formal theoretical model, based on Bayesian approach, to be dynamically updated to use appropriate combinations of authentication factors in response to changes in the security environment. The model is important because it forms the basis on which the real-world systems is able to be evaluated security immediately and responded to weak factor.
