A Comprehensive Study on Big Data Security and Integrity Over Cloud Storage

In this paper, a study on cloud storage security issues and challenges such as authentication, access control, policy integration, service management, trust management, data security, regulatory compliance, privileged user access, etc are presented. In the first half of the paper, a survey on generic security issues in cloud storage is presented which suggests that third party auditor based security is best for cloud environments.
