Abstract—With the development of medical technology and informationtechnology, the “personal health records (PHR)” is gradually developed as a up-to-date medical information exchange system. Aproper patient-centered PHR systemis able tooffer correct and complete personal health and medical summary through the Internet under the demands of privacy and security, and integrate personal medicalinformation from different sources. With the appearance of Cloud computing, a secure protection scheme is required to encrypt the medical records of each patient for storing personal health records into Cloud server. Therefore, we proposed in this study a new PHR access control scheme based on Lagrange interpolation polynomial under Cloud computing environments. This proposed scheme provides legitimate authorities to access to PHR, and dynamically supports multi-users in Cloud computing environments with personal privacy.
Index Terms—Personal health records, cloud computing, access control, key management, Lagrange interpolation.
