Once the Abstract -Progressively more associations are picking outsourcing information to remote cloud service providers (CSPs). Clients can lease the CSPs stockpiling framework to store and recover practically boundless measure of information by paying expenses metered in gigabyte/month. For an expanded level of versatility, accessibility, and solidness, a few clients may need their information to be imitated on different servers over various server farms. The more duplicates the CSP is requested that store, the more expenses the clients are charged. Hence, clients require to have a solid certification that the CSP is putting away all information duplicates that are settled upon in the administration contract, and every one of these duplicates are predictable with the latest changes issued by the clients. In this paper, we propose a map-based provable multi-copy dynamic data possession (MB-PMDDP) conspire that has the accompanying components: 1) it gives a proof to the clients that the CSP is not deceiving by putting away less duplicates; 2) it underpins outsourcing of element information, i.e., it underpins piece level operations, for example, square adjustment, addition, erasure, and affix; what's more, 3) it permits approved clients to consistently get to the record duplicates put away by the CSP. We give a near examination of the proposed MB-PMDDP conspire with a reference show acquired by augmenting existing provable ownership of element single-duplicate plans. The hypothetical investigation is approved through test comes about on a business cloud stage. Furthermore, we appear the security against intriguing servers, and examine how to recognize defiled duplicates by marginally changing the proposed conspire. Key Words: Cloud Computing, Data Replication, Outsourcing, Data Storage, Dynamic Environment.
1. INTRODUCTION OUTSOURCING information to a remote cloud service provider (CSP) permits associations to store more information on the CSP than on private PC frameworks. Such outsourcing of information stockpiling empowers associations to focus on developments and assuages the weight of steady server overhauls what's more, other registering issues. In addition, many approved clients can get to the remotely put away information from various © 2017, IRJET

information has been outsourced to a remote CSP which may not be dependable, the information proprietors lose the coordinate control over their touchy information. This absence of control raises new imposing and testing errands identified with information classification and honesty security in distributed computing.
The classification issue can be taken care of by scrambling touchy information before outsourcing to remote servers. In that capacity, it is a significant request of clients to have a solid proof that the cloud servers still have their information and it is not being messed with or incompletely erased after some time. Therefore, numerous scientists have concentrated on the issue of provable data possession (PDP) and proposed distinctive plans to review the information put away on remote servers. PDP is a method for approving information honesty over remote servers. In a run of the mill PDP demonstrate, the information proprietor produces some metadata/data for an information record to be utilized later for check purposes through a test reaction convention with the remote/cloud server. The proprietor sends the record to be put away on a remote server which might be un-trusted, what's more, erases the nearby duplicate of the record. As a proof that the server is as yet having the information record in its unique frame, it needs to effectively figure a reaction to a test vector sent from a verifier — who can be the first information proprietor or a trusted substance that shares some data with the proprietor. Specialists have proposed distinctive varieties of PDP conspires under various cryptographic suppositions; for case, see [1]–[9]. One of the center plan standards of outsourcing information is to give dynamic conduct of information to different applications. This implies the remotely put away information can be definitely not just got to by the approved clients, additionally upgraded and scaled (through piece level operations) by the information proprietor. PDP plans exhibited in [1]–[9] concentrate on just static or warehoused information, where the outsourced information is kept unaltered over remote servers. Cases of PDP developments that manage dynamic information are [10]–[14]. The last are in any case for a solitary duplicate of the information record. Despite the fact that PDP plans have been exhibited for different duplicates of static information, see [15]–[17], to the best of our insight, this work is the main PDP conspire ISO 9001:2008 Certified Journal
