The trend of using cloud environments is growing for storage and data processing needs. Cloud computing is an internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand. The idea is to construct a new privacy preserving access control scheme for securing data in clouds. The cloud verifies the authenticity of the user but cloud does not know user's identity. User should need to authenticate before storing the data. This is also prevents replay attacks and supports creation, modification, and reading data stored in the cloud.
