Paper based medical consulting system has been replaced by electronic health monitoring system due to features like low cost, on demand global accessibility, reliability, accuracy and mobility. Generally, mobile healthcare system collects patient’s sensors data and after processing it gives personal health record(PHR). Computation and communication cost should also be taken into consideration. Hospital provides monitoring program for processing sensors data and providing PHR to patients. Grievously, if millions of patients come at a time then hospital can’t handle their request due to lack of computation power and storage. Therefore, hospital seeks help of cloud for processing of PHR. Although outsourcing comes with a price of security and privacy of data owner. Here, patient has to provide identity to the public domain which should be preserved. Also, cloud can create wrong PHR by mistake, which can dangerously affect patient’s life. Hospital provides it’s monitoring program to cloud, therefore security of monitoring program is also required. In this work 1, we have proposed a protocol for identity verification on cloud side without actually revealing identity of patient and gives verification of PHR.We have analyzed and experimented our protocol that shows, security strength and efficiency comparison with related scheme.
