Cloud computing is one of the latest and an ever growing technology. Cloud computing provides the service over the internet. In the traditional approach there is no verification of the data in the cloud server if the data is modified and no notifications are sent to the data owner if the file is modified. Authentication of the users is not done properly or it is insecure. The better approach is that the data at the cloud server is verified and notification messages are sent to the data owner. Before uploading the data to the cloud server based on the file size and amount of space acquired by the file the verification is done at the cloud server.
