Now a day’s use of cloud computing is rapidly increasing. Cloud infrastructure is being a common solution adopted by large organizations for storing and accessing data. It provides the current need for data storage with a flexible and dynamic storage that can grow. In this paper, we describe the design and development of a cloud computing based secure cloud data storage using encryption. Cloud data storage is a major solution to overcome this problem. These mechanisms to provide data integrity and security for client’s data in cloud storages. In users should be able to just use the cloud storage as if it is local, without worrying about the need to verify its integrity. This understands the trend in terms of complexity and strength of a secured solution and provides some insights of what is still left in such area of research. Cloud data storage provide better privacy as well as ensure data availability and reliability can be achieved by dividing the user’s data block into data pieces. Cloud storage is of critical importance so that users can resort to a third party auditor (TPA) to check the integrity of outsourced data and be worry-free.
