A EVIDENCE MULTICOPY DYNAMIC DATA POSSESSION IN MULTI CLOUD COMPUTING SYSTEM

G. Venkata Tejaswi, B. Subba Reddy

Abstract


Now a day more and more organizations increasing and are opting for outsource data to remote cloud services provider .the customers can rent the CSPs storage infrastructures to stores and retrieves almost unlimited amount of data by paying fees metered in gigabyte/month. In this paper, proposes a map-based provable multicopy dynamic data possession (MB-PMDDP) scheme that’s has to follows features: 1) its provide an evidences to  customer that the CSPs is not going to  cheat by storing the copy of data; 2) its support outsourcing of dynamic data and its support block levels operation,  such as block modifications, insertion, deletion, and append; and 3) it allows authorized users to seamlessly access the file copies stored by the CSP. It gives a comparative analysis of the proposed MB-PMDDP scheme with a reference model obtained by extends existing provable possessions of dynamics single copies scheme.
