Design on Data Privacy Protection Model for Cloud Environment

JP2Considering the issue of the existing cloud storage privacy security, the dissertation proposes the approach of using the file storage structure and attribute-based encryption, to resolve the problem of cloud storage data privacy security, and explore a security model that can support the privacy protection of user data. The essence of the method is to encrypt user privacy data by the way of combining the attribute encryption and file storage structure, and provides Fine-grained access control. The result shows that the model can effectively protect user privacy data, and improve the level of data security protection and reliability through the security model demonstration.WTHZKey words:WTBZcloud storage; privacy security; attribute-based encryption; access control
