Description
Technical Field
The embodiment of the invention relates to computer technology, in particular to a method, a device, a system, equipment and a medium for isolated playback of a webpage video.
Background
Web page isolation is a technique that involves web browsing activity in an isolated environment (such as a sandbox or virtual machine) to protect computer users from any malware that may be encountered. This isolation may occur on the local computer or on a remote server. Remote web page isolation, i.e., virtualization and isolation, occurs on a remote server. The user's browsing activity is transferred to a remote virtual environment, and the content browsed by the user's computer is a real-time visual stream occurring on a server. In short, the user does not use a local browser to directly surf the internet, but connects to a remote server and surfs the internet by using a remote browser on the server. The whole-course data only falls on the remote server and does not fall on the local.
The remote web page isolation of the prior art is usually based on DOM (Document Object Model) and pixel push implementations. The DOM-based web page isolation system will filter out certain types of web page content that it considers dangerous, but still allow certain types of web page content to be sent directly from the internet to the user's computer in its original form; while an isolation system that delivers visual streams on a pixel basis does not send any web content to the user's computer, it only sends visual streams in pixels. In any implementation, if there is video content in the web page, the web page isolation is not easy to transmit the video to the client through the remote isolation server for synchronous playing. Most isolation systems currently adopt a transparent transmission scheme, that is, if the video is, the URL (uniform resource locator) is released, and no isolation is performed.
In the process of implementing the invention, the inventor finds that the prior art has the following defects: in the prior art, a webpage isolation system based on DOM cannot restore the video of a webpage to a DOM tree, so that the video cannot be transmitted to a client side for synchronous playing; although the isolation system based on pixel transmission visual stream can transmit video images synchronously, the isolation system also has the problem that the synchronous playing of sound and pictures cannot be realized.
