Pawar P. R, Aarti Waghmare · 2015
Cloud storage has become so popular in a now days not because of its cost efficient on demand usage but because of provision of huge amount of storage on which user can easily outsource its data. Most of the surveys told that nearly half of consumed storage on cloud is occupied by duplicate files or data. Challenge in front of today’s cloud services is the management of that huge increasing quantity of data. To make data management scalable, de-duplication is introduced. In deduplication, instead of storing multiple copies of data which are exactly identical, it keeps only one physical copy. Security and privacy are among top concerns for the public cloud environments. This Data confidentiality for users is achieved with Convergent Encryption instead of Traditional encryption.
