Abstract
A method, system, and computer readable medium containing programming for handling fully authenticated transmission of video or other data (content) from a provider to a recipient device via an intermediary device. An inner envelope containing the content and/or security features is prepared and digitally signed using a private cryptographic key. The signed inner envelope is then included in a second, outer envelope which may also include some or all of the content. The outer envelope is also digitally signed, thereby forming a data package which may be sent from the provider to the intermediary device. If the signature of the outer envelope is authenticated at the intermediary device, then the inner envelope is sent to the recipient device which then uses the inner signature to verify its authenticity. Authenticated content may then be presented or otherwise used at the recipient device.
