Method and apparatus for validating security components through a request for content |
摘要 |
A system and method of controlling use of content in accordance with usage rights associated with the content. A request for content is analyzed by looking for a signature from a user device making the request to determine if the user device has security components for enforcing the usage rights. If the request does not have the signature, a software agent is sent to the user device to determine if the user device is secure and the request is resent with the signature if the user device is secure. Content is rendered with a rendering engine of the user device in accordance with the usage rights in response to the resent request.
