Cloud computing is a rising computing technology. It permits users, store their data, knowledge or information remotly.The purpose of this paper is to secure access control scheme for public clouds. We present a "Privacy Preserving Two Layer Encryption Access control in Public Clouds”, Which provides more security and privacy as compare to the tradition approaches. Current approaches to enforce access management polices(ACPs) on outsourced data using selected encryption require organizations to manages all keys and encryptions and upload encrypted data on the remote storage. Such type of approaches incur high communications and the computation cost to manage keys and encryptions whenever user make changes. To solving this problem by delegating as much of the Access Control enforcement responsibilities as possible to the cloud while reducing the information exposure risk due to colluding users and Cloud.
