Enhanced Data Sharing by Decentralized and Lightweight Framework for Accountability in Cloud Storage
Keywords:Cloud Computing, Distributed Data Sharing, Information Accountability, Access Control, Auditing
Cloud computing environment provides a large-scale distributed storage system where, resources on the internet are considered as a unified entity. Users use services without knowing the machines which actually process and host their own data and how computation and data storage is managed. While enjoying the convenience brought by cloud computing, the problem of losing control of user’s own data from them is becoming a significant barrier to wider adoption of this emerging technology. Therefore, users need a mechanism for transparent data usage of the user’s data in the cloud. For achieving this goal an information accountability framework called Cloud Information Accountability is proposed in this paper which provide highly decentralized and light-weight framework to keep track of the actual usage of user’s data in the cloud. CIA provides automated logging, authentication and distributed auditing mechanism to strengthen user’s control over their data.
