Protected media stream source

摘要

A media stream source protection system in which a media stream is passed through a gatekeeper before being used by any other software or hardware within the information handling system. In certain embodiments, the video camera encrypts and the gatekeeper decrypts content received from the video camera before the content is provided to the gatekeeper. In certain embodiments, the encryption is performed on the camera device as part of the video encode incorporated the video camera thus providing a bandwidth-saving measure.

主权项

1. A method for providing media stream source protection to an information handling system comprising:
executing a driver to control the camera; coupling a gatekeeper component with the driver, the gatekeeper component providing media stream source protection function to the driver; maintaining the gatekeeper component in a first position within a filter graph; and, confirming the gatekeeper component is located in the first position within the filter graph; and wherein if the media stream is intercepted prior to receipt by the gatekeeper component, the stream is not usable and is not forwarded beyond the gatekeeper component.
