Cloud computing has been enabling its users to access the shared resources through internet reduced cost resource utilization. The security for the data in cloud is very important. Data integrity refers to maintaining and assuring the accuracy and consistency of data over its entire life-cycle, and is a critical aspect to the design, implementation and usage of any system which stores, processes, or retrieves data.
