SECURED AND REVOCABLE AUTHENTICATION AND SHARING SYSTEM USING SMART-CONTRACTS FOR CLOUD DATA

Abstract

In cloud environment, data is stored and shared among multiple nodes. This data is managed by third party, may have security, revocability and authenticity issues. Data sharing and exchanging services are being needed in every field i.e education, banking, health etc. In this case study medical dataset is used. As medical sector is more personal and crucial process, health records have a lot of medical and personal information of individuals. Electronic Health Records (EHRs), are digital format in which highly private information related to the diagnosis and treatment of patient is stored and it is also needed to share with peers. Hence, sharing of health records between participants is very challenging because the data might be leaked or tampered during the exchanging process. A secure and revocable data authentication system is proposed to overcome these issues in data sharing. Also modern Hybrid encryption techniques is implemented to share data via secure channel. The enhanced results and some comparisons are shown in the results section.
