A Survey on Data Redundancy Check in a Hybrid Cloud by using Convergent Encryption

Background/Objectives: Data deduplication is the elimination of redundant data within an existing environment. It is mainly used in cloud storage environment for bandwidth optimization and to enhance storage space. This paper focuses on different dedupe techniques with a secure cloud. Methods/Statistical Analysis: Symmetric key encryption is used to prevent unauthorized user from accessing the data. Convergent key encryption algorithm is used to encrypt and maintain data confidentiality. Findings: In the proposed system the authorized data deduplication is achieved with minimal overhead when compared with traditional deduplication.
