In cloud storage efficiency and data integrity are the two important requirements. This benefits in sparing efforts on heavy data maintenance, management. Single copy of each file is stored in cloud even it is owned by number of users. By reducing reliability deduplication system improves the storage utilization. In this paper we study the problem of integrity auditing and secure deduplication on cloud data and to recovering the files in case of the file deletion or if the cloud gets destroyed due to any reason. To achieve both data integrity and deduplication in cloud, presenting two secure systems SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintainence of a MapReduce cloud,which helps clients create data tags before uploading as well as audit the integrity of data having been saved or stored in cloud. SecCloud+ is designed that customers always want to encrypt their data before uploading and enables integrity auditing and secure deduplication only on encrypted data. Focuses on the security concept for the back-up files stored at proxy server.
