Privacy-Enhanced Data Deduplication Computational Intelligence Technique for Secure Healthcare Applications

A significant number of cloud storage environments are already implementing deduplication technology. Due to the nature environment, a server capable accommodating large-capacity is required. As capacity increases, additional solutions By leveraging deduplication, you can fundamentally solve cost problem. However, poses privacy concerns due structure itself. In this paper, we point out infringement problem and propose new technique it. proposed technique, since user’s map files not stored on server, file uploader list cannot be obtained through server’s meta-information analysis, so maintained. addition, personal identification (PIN) used ownership provides advantages such as safety against insider breaches sniffing attacks. The mechanism required an time approximately 100 ms add IDRef distinguish user-file during typical for smaller sizes, operations similar operation time, but relatively less file’s grows.
