A Methodology for Secure Sharing of Personal Health Records in the Cloud

Abstract

In the health care sector has resulted in value effective and convenient exchange of nonpublic Health Records (PHRs) among many taking part entities of the e-Health systems. still,
storing the confidential health data to cloud servers is prone to revelation or larceny and
demand the event of methodologies that make sure the privacy of the PHRs. Therefore, we
tend to propose a technique referred to as SeSPHR for secure sharing of the PHRs within 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 by selection grant access to differing types of users on totally different
parts of the PHRs. A semi-trusted proxy referred to 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 business executive threats and conjointly
enforces a forward and backward access management. Moreover, we tend to formally
analyze and verify the operating of SeSPHR methodology through the High Level Petri Nets
(HLPN). Performance analysis concerning time consumption indicates that the SeSPHR
methodology has potential to use for firmly sharing the PHRs within the cloud. conjointly we
tend to Implement as a contribution during this paper time Server, Secure Auditing Storage,
in Time Server PHR Owner add the start and Ending time attach to uploaded Encrypted files,
and conjointly implement the TPA Module for verify the PHR Record its hack or corrupted
for the other hacker and wrongdoer if information hack from hacker facet discover all system
details of wrongdoer like Macintosh Address and information science Address its our
contribution in our project.
