Data Possession Of Multiple Replicas Across The Distributed Storage System By Third Party Auditor
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 11
Abstract
Cloud computing has four models as Public cloud through which the service is obtainable to all public use. Private cloud through which service is accessible to private enterprise or organization. Community Cloud permits us to share infrastructure among various organizations through which we can achieve security, compliance and jurisdiction. Users should be able to just use the cloud storage as if it is local without worrying about the need to authenticate its integrity. Thus enabling public audit capability for cloud storage is of critical importance so that users can resort to a third party auditor (TPA) to check the integrity of outsourced data and be worry-free. To securely introduce an effective TPA the auditing process should bring in no new vulnerabilities towards user data privacy and introduce no additional online burden to user. In this we propose a secure cloud storage system supporting privacy-preserving public auditing. We further extend our result to enable the TPA to execute audits for multiple users simultaneously and efficiently.
