Paper Title
Efficient Provable Multicopy Dynamic Data Possession Method Over Cloud Servers
Abstract
The many organizations are adopting to use outsourcing data to remote cloud service providers (CSP).The CSPs
storage infrastructure can be rented by customers to store and get back unlimited amount of data by paying fees per
gigabyte/month. To achieve higher level of scalability, availability the data must be replicate on multiple servers among
multiple data centers. If the more copies the CSP is asked to store, the more fees the clients are charged. It is very important
to the clients to have strong evidence that they actually get the service they pay for, and all these copies are reliable with the
most recent modifications done by the clients. Efficient provable multicopy dynamic data possession (EPMDDP) method
being proposed in this paper and includes following features; It provides an proofs to the clients that the CSP not cheat by
storing fewer copies, It supports outsourcing of dynamic data, i.e., file level functions such as file alteration, addition,
deletion, and append, and finally It allows only authorized users to access the file copies stored by the CSP.
