Abstract

The invention provides a protection method and a protection device for video devices of a computer, and relates to the technical field of computers. During processing procedure of the protection device, any request message packet of an application process is not subjected to forced interruption; only video data of a request packet with video stream data is replaced by replacement data having the same format of video, communication between the application process and the video devices are not interrupted in a forced and violent manner, a normal interaction protocol between the application process and the video devices is not broken either, the video devices cannot be considered as being damaged and cannot be accessed again by the application process, and the application process can access the video devices again without being rebooted. In addition, a user terminal is prompted to select whether to allow interruption or not after the video stream data of the video devices is acquired by the protection device, so that false positives can be avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a computer video equipment protection method and device. Background technique [0002] With the development of Internet technology, users can perform video interaction with other users through video devices (such as cameras) on the Internet, and on the Internet, many applications can open video devices to obtain video information at the user end. During use, if a user does not pay attention to the management of video equipment, other users on the Internet may obtain video information that the user does not want to disclose, especially for hackers, it is easy to obtain user information through remote operation and control of video equipment. terminal video information. [0003] In the prior art, the protection technology for video privacy is to use the windows kernel HOOK technology to intercept the process of opening the camera, that is, when a process opens the user...
