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
