Handle the privacy information in the cloud faces the lot of security issues. If we maintain the medical information in the cloud means we need to provide the more security protection for the sensitive information's. Personal Health Information system is the system for preserving the privacy and distributing the information in secret way using Cloud Computing. Storing the medical information in third party cloud server, there is the chance for viewing and there is the chance for the information leakage. So here we need to protect the sensitive information's. The better way to protect the medical information's is, storing the sensitive information in the form of cipher text. In this paper we made a detailed study on Attribute Based Encryption and Attribute Based Broadcast Encryption for securing the Personal Health Information. And also in this paper we present the Personal Health Information system and we implement the system from different angle for securing the Personal Health Information with the help of Asymmetric key Cryptography and Message Digest. And also we are using the Attribute Based Broadcast Encryption. And we present the Time Granularity based log record scheme. To maintaining the log record we using the Third Party Auditor for strong back end protection. We show the experimental result of the PHIS in this paper.
