Abstract
This paper proposes a two factors user authentication scheme for Beijing medical registration platform, in order to protect user personal information on the platform. This scheme overcomes the shortcoming that there is no authentication process during user log on the platform. The reason that builds a two factor authentication scheme for the system is that this way is safer than traditional single factor user authentication methods, e.g., typing username and password, or biometric authentication. For the proposed two factor user authentication scheme, we give three different solutions, including SMS-OTP solution, NFC-enabled device solution, and biometrics based solution. Finally, an optimal solution is chosen as the formal one to the platform through comparisons at a different angle among these three solutions. Keywords-two factor authentication; SMS-OTP; NFC; biometrics
