Cloud computing is a distributed system which supports various types of services like SAAS, IAAS and PASS. The data resides with in the cloud is vital, hence there is a need to preserve the data as well as to maintain the privacy of cloud users. In conventional access control mechanisms, on granting the access right, the data will be completely available at the service provider.
