DEDUP: Deduplication system for encrypted data in cloud

Cloud computing facilitates different cloud services in which the most popular one is cloud storage. For maintaining the privacy and security of data, the data holders often store their data in encrypted form. Further the encrypted data introduce new problems for deduplication while processing such a crucial big data. The present schemes of data deduplictaion in encrypted form lacks in security. Most schemes do not support access on data thus creating a big challenge of ownership on data being stored on cloud. In this paper, we have proposed a DeDup App which is easy to use application interface based on challenge of ownership and re-encryption. The efficiency of our scheme is a result of the computer simulation and analysis performed.
