Over the past few years, cloud computing has develop into more and more admired. It brings revolutionary innovation with regards to cost, resource management and utilization. Cloud computing offer nearly unlimited resources, highly reliable on-demand services with minimal infrastructure and operational cost and storage system. In the cloud storage system with data de-duplication, un-trusted entities including a cloud server and users may cause security threats to the storage system. These services offers to end-users rather than a product by sharing resources, software and other information, hence economic benefit and data de-duplication is the key for Cloud in terms of capital and operational expenditure.
