Multi-Drive File Operation with Secure Authorized Data De-duplication

Abstract

With the evolution of wireless communication technology, mobile devices have perform more and more important roles in the people's daily lives. However, data storage and sharing are hard for these devices due to the data inflation and natural extent of mobile devices, For this, we present a lightweight Multi-cloud-based storage framework, in which the data owner can access their data via network at any time and for anywhere by uploading data into the cloud. Generally speaking, each cloud drive will just free provide a small storage space. Thereby, a big one will come into start after adding all free space of this cloud drives together. For instance, if you have registered five Drop-box accounts and each one has offered 2GB free space, you can use the free 10GB space conveniently with the help of Multi-Cloud. To better protect data security, the first attempt to formally address the problem of authorized data de-duplication. Data de-duplication is one of the important data compression techniques for eliminating duplicate copies of repeating data and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth .We develop this project in ASP.net technology and also use O-Auth technique for authentication.
