Abstract

User authentication is necessary for proving and verifying the claimed identity of users in a distributed environment. Three factors such as user's knowledge, belongings, and biometric traits are usually considered for the purpose. A sort of multi-factor authentication may combine those factors in the way that a user provides the requested multi-factors separately, for improving the accuracy and security of authentication. However, such a combination of distinct factors should require each different human-computer interfaces. In this short paper, rather we introduce our on-going work to associate knowledge-based authentication with biometrics for requiring less interfaces and examine the benefits expected from it in a conceptual level.
