Fine-grained access control mechanisms on secure data in the cloud are based on encryption of the data in fine-grained approach. In these approaches, owners of the data in cloud encrypt the data before uploading them on the cloud and re-encrypt the data whenever user credentials change. Owners of the data also known as data owners thus generate high costs in terms of communication and computation. A better approach should be used that delegates the enforcement of fine-grained access control to the cloud, minimizing overhead at the data owners. Also assure data confidentiality from the cloud.
