Dynamic Proof of Storage (PoS) is a profitable custom that empowers a customer to see the respectability of outsourced reports and invigorate the records in a cloud server with an extraordinarily compelling way. Despite the likelihood that a couple of agents have formed unmistakable dynamic PoS in unit customer circumstances, however the inconvenience in multi-customer conditions has not been asked inside and out. A shrewd multi-customer appropriated capacity structure needs the ensured client side cross-customer deduplication framework, that gives a customer to avoid the exchanging strategy and getting the responsibility for records now, once resulting proprietors of a similar archives have exchanged them to the cloud server. To minimal complex of our data, no other present dynamic PoS will support this system. In this paper, we are talented to exhibit the possibility of deduplicatable dynamic check of limit related propose a saving improvement suggested as DeyPoS, to recognize dynamic PoS and secure cross-customer duplication, meanwhile. Considering the troubles of structure contrasts and individual name period, we tend to abuse an exceptional instrument insinuated as Homomorphic Authenticated Tree (HAT). We have a tendency to show the protection of our advancement.
