Framework for Multilevel Privacy and Backup of Cloud Storage with CDMBackupSim

摘要

Cloud computing gives an enormous support to an individual and enterprise which can improve their needs in the global market. The customer's data are stored in different location in the cloud either in same or different region. These data should be handled securely from requester to provider end. The cloud security involves protecting and controlling the data, application and associated infrastructures by imposing the policies, technologies etc. The privacy is used to secure processing and handling the personal data in the cloud is not disclosed by the unauthorized parties. The cloud suffers a reliability issues due to lack of security and privacy over the data. The security levels are confined into a particular boundary which does not cover all access levels. The privacy information of various levels is handled by introducing a multilevel privacy technique for protecting user's data in various boundaries. The proposed framework gives an alert whenever the data are accessed by the Cloud Service Provider (CSP) or any other parties, so this will help the Cloud Service User (CSU) to know the status of data. The proposed work is simulated by introducing CDMBackupSim simulator which has various modules and it gives the simulated result for testing process.
