Cloud services act as storage center in the health sector which enables the exchange of EHR among the hospitals & clinics. Due to the unsecure cloud violation we should essentially consider security and privacy mechanisms. By searching from the hospital management, user will discover and to allow storing, updating and sharing electronic health records (EHR), so called personal health records (PHR). Moreover, user can found features like family trees, emergency solutions, laboratory tests and care plans. The entire work can be progress on this proposal. Multi nominal entities has been enter and sharing the information on cloud. In order to keep secure the Bio medical information on cloud storage proposing a valuable crypto graphic encryption/decryption technique has been developed here. To verify and determine the privacy information process by using an efficient blow fish technique. Inside and outside patients are able to authorize access to their records and time-independent for later processing by the physician. The security of our approach relies on modern cryptographic schemes and their incorporation into an EHR infrastructure.
