The Personal Health Record (PHR) framework converts a general clinical history of paper into a web-based electronic record. In this framework, a patient could share, oversee and control his PHR with approved clients, for example, family members, companions and wellbeing care [1]. EHR is a source that focuses on capturing clinical history and treatment of patient health information. These important patient-centered records can be successfully accessed by all authorized medical service providers (research institutes, authorities etc.) [2]. The method empowers an individual to collect, store, oversee, and share his state of being information inescapably. But with the advantages of these PHR systems there are so many flaws related to security. Different cryptographic techniques are used to encrypt the data and make it secure. After applying different techniques, the data on the cloud is now much more secure than before.
