摘要：Cloud co mputing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. A major feature of the cloud services is that users' data are usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users' fears of losing control of their own data (particularly, financial and health data) can become a significant barrier to the wide adoption of cloud services. To solve the above problem in this paper we provide effective mechanism to using accountability frame work to keep track of the actual usage of the users' data in the cloud. In particular, w e propose an object-centered approach that enables enclosing our logging mechanism together w ith users' data and policies. Accountability is checking of authorization policies and it is important for transparent data access. We provide automatic logging mechanisms using JAR programming which improves security and privacy of data in cloud. To strengthen user's control, we also provide distributed auditing mechanisms. We provide extensive experimental studies that demonstrate the efficiency and effectiveness of the proposed approaches.
