Abstract — Cloud storage enables users to remotely store and retrieve their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Cloud storage system enables storing of data in the cloud server efficiently and makes the user to work with the data without any trouble of the resources. Cloud computing is highly promising technology because of its unlimited resource provisioning and data storage services which help us in managing the data as per requirements. In the existing system, the data are stored in the cloud using dynamic data operation with computation which makes the user need to make a copy for further updating and verification of the data loss. An efficient distributed storage auditing mechanism is planned which over comes the limitations in handling the data loss. In this work the partitioning method is proposed for the data storage which avoids the local copy at the user side by using partitioning method. The cryptography technologies offer encryption and decryption of the data and user authentication information to protect it from the unauthorized user or attacker. This method ensures high cloud storage integrity, enhanced error localization and easy identification of misbehaving server. To achieve this, remote data integrity checking concept is used to enhance the performance of cloud storage. The data is stored in cloud datacenter hence this work aims to store the data in reduced space with less time and computational cost. Cloud storage is flexible with reduced cost and manages the data from loss risk. The Cloud server allows user to store their data on a cloud without worrying about correctness & integrity of data. Cloud data storage has many advantages over local data storage.
