A Survey on Deduplication Scheme in Cloud Storage

Due to less maintenance enterprises and organizations outsource data storage to third-party cloud providers. Due to increase in data volume there is a need of data management in cloud storages. Deduplication is a technique which eliminates duplicate copies of same data. To make data management scalable, deduplication has been a well-known technique to reduce storage space and upload bandwidth in cloud storage. So we are going to build a deduplication mechanism which makes use of a convergent encryption scheme for data confidentiality. We also enhance our deduplication mechanism by solving the key management problem cause by generating an enormous number of keys with the increasing number of users in the convergent encryption using the Ramp secret sharing scheme.
