Efficacious applicability of foolproof security and reliable storage services in cloud computing

Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Though the benefits are clear, such a service is also relinquishing users´ physical possession of their outsourced data, which inevitably poses new security risks toward the correctness of the data in cloud. we propose in this paper a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded data. Also an third party auditor for the auditing mechanism.
