Advanced video camera privacy lock |
摘要 |
A video camera privacy lock is set forth. The video camera privacy lock includes a low level filter driver that install and maintains a first position in a filter graph. The filter driver provides a locked media signal to the next sequential item rather than to a media stream until and unless the filter is unlocked. The locked media signal may be a blank screen, a text message, an icon, a static image (such as an avatar, a photograph, etc., pixilated video, or some other predetermined output). Also, in various embodiments, the driver is locked by default, thereby increasing user trust that the video camera only transmits a media signal when desired. |

executing a filter driver to control the camera; maintaining the filter driver in a locked condition so that a media stream from the camera is not passed beyond the filter driver, the maintaining the filter driver in the locked condition providing a camera privacy lock to the camera; and, upon detection of a predetermined event, transitioning the filter driver to an unlocked condition, the unlocked condition transmitting the media stream from the camera to a next sequential item of the information handling system. |
