Secure Data Control: Privacy and Security based on ABE for Access Control over Cloud

In today's world, there is a strong requirement for sharing information over cloud. However, privacy and security remains a setback especially when working with bulk amounts of data in the Cloud. Data is abundantly stored outside the control of the data owner’s machine with lack of his knowledge to the data owner, how the data being used and where the data are being stored. So, there is a necessity for the data owner to have a more control over their data, similar to the level of control they possess when the data are being stored on their own machine. For example, when a data owner shares an important file with his colleague, he cannot trust what his colleague will do with his data. In this paper, we try to address this problem by monitoring and preventing unauthorized operations by the data consumer. We present a solution called Secure-Data, which bundles the data owner’s data and specified policy, based on XACML, in an object called Secure-Data object. Secure-Data enforces the policies set out by the data owner by communicating with the cloud based applications to disable certain operations and/or run a background process for monitoring the data. We define a software based protocol that will enable to secure the data in the cloud and will support the use of the android app for authentication purposes
