Cloud Computing is a technology that provides network based services on-demand. Data owners host their private data in the cloud and worry about unauthorized access of their data. They feel uncomfortable about any user misusing their private data. This insecure feeling of data owners holds them back from using cloud services. Any unauthorized users accessing the owner?s private data leads to accountability issues. To solve the accountability issue, a mechanism to monitor the actual data usage is proposed. This approach grants access rights to users based on their role and also monitors every access to the owner?s data, verifying that the service level agreements have been violated or not.
