Apply Lagrange Interpolation Based Access Control Mechanism in Personal Health Record Medical System

Abstract

This study applied a Lagrange Interpolation based access control mechanism in the cloud Personal Health Record (PHR) system. We proposed an access control mechanism to make sure that health care information sharing is secure through the public key cryptosystem and Lagrange interpolation. Additionally, the access authority and the privacy setting have to be confined severely when we consider personal health records and private information. The PHR ought to prevent unauthorized users on the top of providing users with the access authority. As a result, we analyzed the mechanism’s security of the network attackers. On the basis of our analysis consequent, the access control and key management mechanism that we proposed can protect the health care information which can be shared among medical institutions efficiently and effectively.
