User Authentication Method Design Based on Biometrics in a Multi-cloud Environment

Abstract

Users in a multi-cloud environment use two or more cloud services and each cloud has an authentication module and user management module. However, in order to use a variety of cloud, users must perform a user authentication for each cloud. At such time, as the user authentication information is stored in various clouds, there are problems of being captured or stolen. In this paper, a user authentication method based on biometrics using biometric information is proposed in order to provide a safe user authentication in a multi-cloud environment.
