An authentication system using smart phones as secure storage

The smart phone penetration rate has increased recently. There are also many commercial terminals for receiving network services. When a service is received by a smart phone or PC, user authentication is very important for ensuring secure and safe use. Currently, authentication is required each time a user changes the terminal on which a service is received. We propose a system that uses a smart phone as a storage device for authentication information, such as ID, password, and cookie information. With this system, the smart phone and various terminals cooperate through short distance wireless telecommunications technologies such as Bluetooth. We evaluate performance of our proposed system. As a result, the user can input authentication information to and receive a service on a terminal by simply swiping the smart phone over the terminal.
