Introduction
Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing
The distributed cloud storage to support the scalability of service and data migration
The proposed scheme based on homomorphic verifiable response and hash index hierarchy
Our resultant focuses on lower computation and communication
overheads in comparison with non-cooperative approaches.
Objectives
Cloud becomes the point by providing a comparably low-cost, scalable, position-independent platform for clients’ data.
We call such a distributed cloud environment as a multi-Cloud (or hybrid cloud). Often, by using virtual infrastructure management
Multi-cloud allows clients to easily access his/her resources remotely through interfaces such as Web services provided by Amazon EC2, Yahoo, Google, Microsoft etc.
Cloud also provide the freeware services to accessing and managing the clients data such various tools and technologies are VM Orchestrator, Vmware, vSphere, and Ovirt.
Conclusion
We have to conclude that the construction of an efficient PDP scheme for distributed cloud storage. Based on homomorphic i.e verifiable response and hash index hierarchy,
Also conclude the PDP scheme to support dynamic scalability on multiple storage servers.
The new proposed scheme provided double layer security properties
Our new approaches only introduce a small amount of computation and communication overheads.
