With the development of information technology and medical technology, developed countries have been establish organization to set standard for electronic medical records in response to new generation and information on the application, they gradually develop emerging medical information exchange mode, Personal Health Records (PHR). PHR can integrate different kind of personal health records. With the Internet or portable device, PHR offers the integrity and accuracy personal health and medical records. Through electronic medical records, we can evaluate the quality of medical care, provide continued care to patients, promote the medical efficiency and increase the accuracy of medical diagnosis. To implement PHR system in Cloud computing environment, we can decrease the cost of managing the infrastructure, and speed up dynamic resource adjustment based on the situation of the changes in client's demand and other advantages. However, it also brings new challenges. It is important to users to assure information security in Cloud environment, so this paper provides efficient and safe access management mechanism to solve PHR implement on Cloud environment's security problem. The information security being threatened in the Cloud may lead to the collapse of medical care, loss of personal data or other serious consequence. Finally, this paper provides new PHR access control mechanism built in Cloud environment with Bilinear Pairing. It provides users with a safe and efficient dynamically access PHR information mechanism. As a result from reserach, through access control scheme, it can withstand equation attack, external attack reverse attack perfectly in Cloud computing environment.
