Abstract
This paper presents a timestamp-based access control mechanism for hospital information system. Including key encryption system, timestamp and Lagrange Interpolation to form a key management and data access mechanism in order to enhance the confidentiality and the level of security in sharing medical information. Hospital information system includes patient’s record and administration management in order to meet the users’ requirement, in the same time, it can improve patient outcome and decrease the cost on management. This mechanism provides an effective management in users’ authority to access the database to prevent data from being stolen or tampered. When the user accesses the electronic medical record, the security performance is greatly improved. It is also necessary to provide legitimate users with decryption key at a particular time.
