An Efficient Data Security Mechanism in Cloud Computing Using Anonymous ID Algorithm

Cloud computing has evolved from a risky and confusing concept to a strategy that organization large and small are beginning to adopt as part of their to overall computing strategy. Cloud computing is a method of providing a set of shared computing resources that includes application, computing, storage, netorking, development and deployment platforms as well as business processes.. Research on the topic of trust in this field has largely focused on privacy-preserving access authority sharing. In this paper, we propose a efficient data security based on privacy-preserving authentication protocol for cloud storage. The users may want to access and share each other’s authorized data fields to achieve dynamic benefits from the cloud environment, which brings new privacy and security challenges in the cloud storage. Shared access authority is achieved by unknown access request matching mechanism with privacy and security consideration (e.g., authentication, data anonymity, user privacy and forward security). An Efficient attribute based access control is adopted to understand that the user can only access their own data field in cloud storage. The Proxy re-encryption will be functional by the server in cloud to provide data sharing among different user. To ability model is established to prove that the Shared an Efficient authority Based Privacy Preserving authentication Protocol has the design correctness and it indicates that the proposed protocol realizing privacy-preserving data access authority sharing is attractive for multiple users in favor of sharing data in cloud application.
