Abstract
A method for delivering content includes receiving the content at an edge server from a content provider, generating an upload signature for the content as received from the content provider where the upload signature includes a hash of the content, receiving a request for the content from a client system, providing the content to the client system, generating a download signature and a screen capture image for the content as provided to the client system, comparing the upload signature and the download signature, and generating an alert when the upload signature and the download signature do not match.
