Data Sharing Accountability in Cloud

Abstract

Cloud computing enable extremely scalable services to be easily consumed over the Internet on an as-needed basis. A most important characteristic of the cloud services is that users‟ information are frequently processed somewhat in unknown machines that users do not own or operate. While enjoying the convenience bring by this novel emerging technology, users‟ worries of losing control of their own data (chiefly, economic and physical condition data) can become a important barrier to the wide adoption of cloud services. To take in hand this problem, in this paper, we propose a new highly decentralized information accountability construction to keep track of the actual usage of the users‟ data in the cloud. In particular, we recommend an object-centered approach that enables enclosing our logging mechanism together with users‟ information and policy. We influence the JAR programmable capabilities[14] to in cooperation generate a active and travelling object, and to ensure that any right of entry to users‟ data will trigger confirmation and automated logging local to the JARs. To strengthen user‟s control, we also offer distributed auditing mechanisms. We supply extensive experimental studies that demonstrate the efficiency and effectiveness of the planned approaches.
