Abstract: The PHR enables patients to manage their medical records in a centralized way which greatly facilitate the storage, access and sharing of personal health data. These details are locked by a central server in the hospital. But the security over the data is loosed while the data is sent to a requester. In this paper, we describe a new scheme for the secure data handling. The CP-ABE scheme is used for this purpose. In this scheme each userís private key is associated with set of attribute representing these capabilities and an encrypted cipher text such that only users whose attribute satisfy a certain policy can decrypt.
