The cloud information administrations, it is typical for information to be put away in the cloud, as well as
imparted crosswise over various Users. A few systems have been intended to permit both information holders and open
verifiers to proficiently review cloud information trustworthiness without recovering the whole information from the cloud
server. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is regarded as one of the most appropriate technologies for
data access control in cloud storage, because it gives data owners more direct control on right to use policies Specifically,
we propose a revocable multi-authority CP-ABE scheme, and apply it as the fundamental techniques to design the data
access control scheme. Our attribute revocation method can competently achieve both forward security and rearward
security. However, it is difficult to directly apply existing CP-ABE schemes to data access control for cloud storage systems
because of the attribute revocation problem. In this paper, we design an expressive,efficient and revocable data access
control scheme for multi-authority cloud storage systems, where there are multiple authorities co-exist and each authority is
able to issue attributes independently
