Data protection in cloud has become an unavoidable and tremendously increasing technology. Many multinational organizations are interested in cloud computing and its wonderful features but they are worried about the security, privacy and availability of data as it rest in the cloud. As more and more sensitive information are centralized in cloud the data protection, security and privacy issues must be tightly considered. In this paper we propose a new cloud computing service called Data Protection as a Service. User authentication, data protection, security are the key areas we consider. User authentication is provided using alphanumeric password and graphical password, security is provided using encryption of the file using key. Key management is an important concept used for the protection of data. Overall transactions are viewed by an auditor. Here multilevel data protection is guaranteed for the cloud users.
