The explosive growth of digital contents continues to raise the demand for new storage and network capacities, along with an increasing need for more cost effective use of storage and network band-width for data transfer.With this increase of data production, shared network multi-user cloud storage systems are becoming very popular.However Security and privacy are among top concerns for the public cloud envi-ronments.Researchers have proposed many dynamic PoS schemes in single-user environments.In this project we propose an improved data deduplication scheme by improving its efficiency by identifying and removing the duplicate copies at block level from the cloud storages in multi-user environments. For implementation we are using message digest hash algorithm (MD5) to generate hashcode and Logical block addressing (LBA) to improve the performance of the proposed deduplication scheme .The security of the system is maintained by DES(Data Encryption Standard) which is a symmetric-key algorithm.
