Cloud Computing Data Security: A Review

Cloud computing has great potential of providing robust computational power to the society at reduced cost. With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the world generate a large amount of data daily. This data would be more useful to cooperating organizations if they were able to share their data. Two major obstacles to this process of data sharing are providing a common storage space and secure access to the shared data. All types of users who require the secure transmission or storage of data in any kind of media or network. We are in great need of encrypting the data. A method to build a trusted computing environment for Cloud Computing system by providing Secure cross platform in to Cloud Computing system. In this method some important security services including authentication, encryption and decryption are provided in Cloud Computing system. In this paper, we propose Data Storage Security by using Trusted Platform Module to achieve storage correctness incorporating Cloud’s dynamic nature while maintaining low computation and communication cost and ensures the security of static data
