Abstract: An application may provide an application identifier to a client as part of a validation request. The client may request a validation token from a server using the application identifier and a user token provided by the client. The server may send a validation token to the client which, in turn, may send the validation token to the application. The application may establish a secure connection to the server and present the validation token to the server as part of a validation request. The server may validate the application in response to the validation request. The server's response may indicate that the application or content contained in the application is licensed.
