In the health care sector has resulted in price effective and convenient exchange of private Health Records (PHRs) among several collaborating entities of the e-Health systems. Therefore, we've a bent to tend to propose how cited as SeSPHR for secure sharing of the PHRs among the cloud. The SeSPHR theme ensures patient-centric management 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 differing types of users on whole totally different components of the PHRs. A semi-trusted proxy cited as Setup and Re-encryption Server (SRS) is introduced to line up the public/private key pairs and to supply the re-encryption keys. Moreover, the methodology is secure against executive threats and put together enforces a forward and backward access management. Moreover, we've a bent to tend to formally analyze and verify the operational of SeSPHR methodology through the High Level Petri Nets (HLPN). Performance analysis regarding time consumption indicates that the SeSPHR methodology has potential to use for firmly sharing the PHRs among the cloud. put together we've a bent to tend to Implement as a contribution throughout this paper time Server, Secure Auditing Storage, in Time Server PHR Owner add the start and Ending time attach to uploaded Encrypted files, and put together implement the TPA Module for verify the PHR Record its hack or corrupted for the other hacker and person if data hack from hacker side discover all system details of person like Macintosh Address and knowledge science Address its our contribution in our project.
