Cloud computing is the delivery of computing as a service rather than a product. It provides shared resources, software, and information to computers and other devices over a network. The increasing network bandwidth and reliable yet flexible network connections make it even possible that users can now subscribe high quality services from data and software that reside solely on remote data centers. People can store and retrieve the data as they like using cloud computing. To maintain the data securely in distributed environment i.e., on clouds they propose an effective and flexible distributed scheme with Token Generation algorithm for data files checking as a secure and dependable cloud storage service.
