Wonbin Kim, Im-Yeong Lee · Advances in Science Technology and Engineering Systems Journal · 2018
Data deduplication technology is used to improve the spatial efficiency of cloud storage.This technology is used for storing data on a cloud and omitting data uploading if the data are already present.However, various security threats may occur during the deduplication process.These security threats include poison attacks and user identity exposure through ownership.In addition, in an environment in which ownership changes in real time, there is a problem in renewing ownership information that has already been issued.Therefore, various studies have been conducted to solve these problems.In this study, a poison attack, real-time ownership management, and ownership anonymization are provided through MLE and dynamic ownership management.
