Proof of Retrievability for Image Data in Industrial Cloud Platform

Abstract

With the increasing popularity of cloud storage, a large number of consumers rent cloud storage services to store their own data. However, with the loss of direct control over data, the integrity and availability of outsourced data become a major concern of users. In order to ensure the reliability and integrity of data in cloud storage server, some scholars have proposed various data integrity auditing schemes.However, most data integrity auditing schemes only focus on single data rather than image data, and only a few articles propose the proof of data retrievability. In order to overcome this difficulty, this paper proposes a scheme of the proof of data retrievability of image data based on industrial cloud. In this scheme, reversible watermarking algorithm is used to verify the integrity of image data, and information dispersion algorithm is used to realize the data retrievability. A large number of security and performance analysis shows that the proposed scheme is efficient and provably secure.
