A MULTI-SERVER DATA SECURITY WITH PUBLIC AUDITING IN CLOUD COMPUTING

摘要

In cloud computing,user share data while sharing data providing security and protecting the data from a unauthorized users is still a demanding problem,so we implement a multilevel data security popular a cloud computing in order to preserve the information using multi-security levels,and provide sufficient multilevel access and validate authorized identity.The recommended scheme is dynamic in multilevel data security,adaptable to certified resource share in,and protected against different malignant strike.Experimentation result checks the feasibleness.The processed data have multiple security level and access permission.
