ABSTRACT: Data sharing is a challenging issue in public cloud storage systems with proper security. In existing system, data integrity auditing scheme that realizes data sharing with sensitive information hiding. However this provide only the security for the sensitive data where it has poor accessible structure during data sharing. In this paper, attribute based encryption technique is used for data sharing technique with the file permission technique. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage. CP-ABE scheme is adopted in a large-scale cloud storage system. This improves the flexible and fast access of the shared data from the cloud.
