Executive Summary

Cloud computing is the use of computing of sources (hardware and software) that are delivered as a service over a network (typically the internet).It enables highly scalable services to be easily consumed over the Internet on an as needed basis. A major characteristic of the cloud services is that users' data are usually processed remotely in unknown machines that users do not operate. It can become a substantial roadblock to the wide adoption of cloud services. To address this problem, the authors propose a highly decentralized answerability framework to keep track of the actual usage of the user's data in the cloud.
