Abstract
Nowadays, personal health records (PHR) has built as a platform for health care data trading. The realistic deployment of PHR in distributed computing infrastructure raises the protection and data security hazards that need to be addressed. However, there have been broad security concerns as personal health data. It could be raised for external servers and treated as unauthenticated cloud servers. The large amount of clients and data owners in the PHR framework who have possibly heavy computational and administration load on the elements in the framework; which will restrict the PHR information accessibility and usability. To find a better solution of above issues, Attribute-based Health Record Protection (AHRP) algorithm is introduced to offer information access control confidentiality, credibility, and secrecy. It is provision of access control to encrypt the information, and a privilege mode for authenticating a message without uncovering the personal information of the patient. Based on Experimental evaluations, proposed Attribute based Health Record Protection Algorithm reduces 0.364 ET (encryption time) in seconds, 0.188 DT (Decryption Time) in seconds for respective records compared than existing methodologies.
