Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data in cloud storage to reduce the amount of storage space and save bandwidth. Traditional encryption techniques are providing data confidentiality which is incompatible with data deduplication. Specifically, traditional encryption requires different users to encrypt their data with their own keys. Thus, identical data copies of different users will lead to different cipher texts, making deduplication impossible. To overcome that de duplication technique used to eliminate redundant data by keeping only one physical copy and referring other redundant data to that copy. Before sending the data to the cloud, the data will be encrypted and it will send the token for security to avoid duplicate data for improving the cloud storage space. Although data deduplication brings a lot of benefits, security and privacy concerns arise as users’ sensitive data are susceptible to both inside and outside attacks.
