ABSTRACT
In a cloud environment where Storage is offered as a service, a client stores his data with a provider and pays as per the usage. Once the contract ends, the client, as the data owner, may like to see, due to privacy reasons and otherwise that the data is properly shredded in the provider storage. In this paper we propose a scheme for Zero Data Remnance Proof (ZDRP) – a comprehensive proof given by the cloud data storage provider as regards to zero data remnance post the SLA period. In absence of such shredding the provider can consume the data to his benefit without coming in legal framework. The proof of data destruction can be achieved together by clauses in the SLA and a comprehensive destruction-verifier algorithm. The implementation of this can be achieved by appropriate modification of the data updation mechanisms provided by open source cloud providers.
