Data Deduplication is a web application technique which is used in reducing storage space and increasing bandwidth. This Deduplication system is mainly important in utilizing storage space of cloud by reducing reliability. Security issues like data confidentiality and data consistency are also achieved by this application. This is achieved by sharing data by secret sharing scheme in distributed system. In earlier systems convergent encryption scheme was used. In this system security analysis demonstrates that system is secure as per definitions specified. As a proof this proposed system is demonstrated that overhead is limited. The main aim of "data Deduplication in cloud by secure auditing" is to provide data integrity and security in storing data, and also achieves data Deduplication methodology. All the files that have to be shared is stored in public cloud as memory can be used efficiently. In this project all users who have to upload the file should register and then by using his /her login details if it is valid then only users can upload the file. Every day batch files are run using the file comparer when the same files are uploaded many times it refers to consuming of memory of cloud hence the redundant data is not necessary then that data has to be destroyed as it consumes memory while it is not necessary. Hence to destroy that data or deduplication has to be done by secure auditing technique. This can be achieved by using file streams like size of the file contents etc if data is matched then the recently uploaded file will be deleted.
