Object oriented accountability approach in cloud for data sharing with patchy image encryption

Cloud computing presents a new approach for delivery model and consumption of different IT services based on internet. Highly scalable and virtualized resources are provided as a service on demand basis. Cloud computing provides flexibility for deploying applications at lower cost while increasing business agility. The main feature of using cloud services is that user's data are more often processed at remote machines which are unknown to user. As user do not own these remote machine used for speed up data processing or operate them in cloud, users can lose control of own confidential data. Despite of all of advantages of cloud this remains a challenge and acts as a barrier to the large scale adoption of cloud. To address above problem in this paper we present object oriented approach that performs automated logging mechanism to ensure any access to user's data will trigger authentication with use of decentralized information accountability framework called as CIA (Cloud Information Accountability) [1]. We use the JAR (JAVA Archive File) programmable capabilities to create dynamic travelling object containing user's data. To strengthen the distributed data security we use the chaos image encryption technique specific to image files. Chaos is patchy image encryption technique based on pixel shuffling. Randomness of the chaos is made utilized to scramble the position of the pixel of image.
