A novel privacy preserving digital forensic readiness provable data possession technique for health care data in cloud

摘要

The scorching challenge calls for an importunate solution in the form of a secure, privacy preserved, economical cloud storage that can weather the turbulence of the rapidly evolving digital storage technologies. This calls for an avid solution, in the form of a public auditing protocol which stands as a testament to establish connection even with an unfamiliar person who must be trusted for sharing of health care data stored in a hermit cloud. The solution should be a technique which aids an external auditor to audit user's outsourced data in the cloud deprived of the wisdom on the data content. The contributions in this paper are (1) A comprehensive analysis of the contemporary privacy preserving PDP data integrity schemes, (2) a novel technique, which, contemporaneously supports the vital functions like Unbounded number of audits, Public auditing, Blockless verification, Stateless verification, data integrity, confidentiality. (3) A framework to direct the data to be safely stored, (4) embed digital forensic readiness into the technique in order to be digitally forensic ready, monitor, plan and formulate proactively before the occurrence of any potential security incidents, (5) implementation of the enhanced PDP technique to validate the auditing performance by existing experimental comparisons with the state of the art techniques. The results validate that the novel integrity technique can competently accomplish secure auditing and outclass the erstwhile ones. Last but not the least, this paper also gives a bird's eye view on the recent research status, and future directions of privacy preserving data integrity.
