A Study on Light-Weight and Efficient Proof of Ownership in Client-Side Deduplication Environment

摘要

Deduplication technology is used to improve the efficiency of data storage space. It involves the prevention of duplicate storing of data by comparing the stored data with the data to be uploaded. However, several security threats arise from this process. Various techniques were proposedto solve this problem by generating a number of operations and communications. This created large loads and reduced the efficacy of deduplication. In this study, we propose a technology that provides better operating efficiency while maintaining the same level of security in order to improvethe inefficiency of the conventional method.
