Survey on Data Deduplication in Cloud Storage Environments

Abstract

Data deduplication technology improves data storage efficiency while storing and managing large amounts ofdata. It reduces storage requirements by determining whether replicated data is being added to storage andomitting these uploads. Data deduplication technologies require data confidentiality and integrity when appliedto cloud storage environments, and they require a variety of security measures, such as encryption. However,because the source data cannot be transformed, common encryption techniques generally cannot be applied atthe same time as data deduplication. Various studies have been conducted to solve this problem. This whitepaper describes the basic environment for data deduplication technology. It also analyzes and comparesmultiple proposed technologies to address security threats.
