Ensuring Distributed Accountability Abstract Ensuring distributed accountability for data sharing in the cloud is in short nothing but a novel highly decentralized information accountability framework to keep track of the actual usage of the users’ data in the cloud. Cloud computing enables highly efficient services that are easily consumed over the internet. One of the important and foremost feature of the cloud is user’s data can be operated or processed in any of the unknown machines that user personally do not own. The feasibility which has occurred due to the new emerging technology user fear of losing the hold on their personal data lets say financial or health related. And this can become an obstruc- tion to the wide adoption of services provided by cloud. Our proposed approach is Object-centered approach which enables enclosing our logging mechanisms together with user’s data and respective policies. Using the JAR programmable capacities to both create a dynamic and travelling object and also to trigger the authentication and automated logging local to the JARs. And to make more secure the user’s control we will be providing distributed auditing mechanisms. Scope: The scope of our system is that we use a private cloud for uploading the Owner’s data. While doing this the owner is not sure about his data, so we will be encrypt- ing his data and then respectively storing it on the cloud. The data would be then wrapped into JAR file along with some access policies. Few algorithms will be used by us while carrying out this task. And finally the user or say owner can access his data safely and securely. Innovativeness and Usefulness: We proposed innovative approaches for automatically logging any access to the data in the cloud together with an auditing mechanism. Our approach allows the data owner to not only audit his content but also enforce strong back-end protection if needed. Moreover, one of the main features of our work is that it enables the data owner to audit even those copies of its data that were made without his knowledge. Department of Computer Engineering I
