Secure and convenient user identity management is particularly important to the success of EMR, EHR, and PHR systems. Unfortunately, widely-used identity management mechanisms that solely rely on username/password are inadequate to meet the strong security and privacy requirements for protecting sensitive user information and medical data. Two-factor authentication approaches that are more convenient and user friendly than existing solutions have been given top priority in the healthcare sector

In this paper, we present a smartphone-based identity management framework-SIM-to enhance the security and usability of user identity management in healthcare information systems. SIM leverages the popularity and computational power of smartphone. Within the SIM framework, a person employs a smartphone to centrally store and manage her identity credentials and authenticates herself to healthcare applications using two-factor authentication without typing any identity credentials. Moreover, SIM provides patients with a patient-controlled authorization mechanism to help patients manage the accesses to their PHRs in a secure and convenient manner. Using an existing EMR system-Arkansas Trauma Image Repository-as an example, we demonstrate that SIM can be applied to a real-world healthcare information system to enhance its protection of user credentials and sensitive information.
