cloud based services in the healthcare sector has resulted in cost effective and convenient exchange of Personal Health Records (PHRs) among several participating entities of the e-Health systems. Storing the confidential health information to cloud servers is not secure, there is issues such as revelation or theft of data and there is need for the development of methodologies that ensure the privacy of the PHRs. Therefore, we use methodology called SeSPHR for secure sharing of the PHRs in the cloud. The SeSPHR scheme ensures patient-centric control on the PHRs and preserves the confidentiality of the PHRs. The patients store the encrypted PHRs on the un-trusted cloud servers and selectively grant access to different types of users on different portions of the PHRs. A semi-trusted proxy called Setup and Re-encryption Server (SRS) is introduced to set up the public/private key pairs and to produce the re-encryption keys. The methodology is secure against insider threats and also enforces a forward and backward access control. Confidentiality of PHR records are maintained by providing password security. Analyze and verify working of methodology with help of SEED based XOR technique.
