Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0023] The present invention will be further described below in conjunction with the examples and drawings, but the embodiments of the present invention are not limited thereto.

[0024] Such as figure 1 As shown, the Qemu (Qemu is a set of free software for simulating processors written by Fabrice Bellard) process runs on the desktop cloud server, starting a desktop will correspondingly start a Qemu process, that is, a desktop runs on a Qemu process Above, the Qemu process communicates with the ...

Abstract

The invention provides a cloud terminal screen recording method. The cloud terminal screen recording method comprises the following steps that (11) a desktop connecting request is detected through a Qemu; (12) whether a request for cutting off desktop connection exists or not is detected constantly in a Qemu process, if the request for cutting off the desktop connection exists, the step (16) is executed, the screen recording of this time is ended, a screen recording file of this time is saved, and if the request for cutting off the desktop connection does not exist, the step (13) is conducted to continue screen recording; (13) a video frame monitoring module is used for detecting whether a desktop operation event exists or not and whether a video frame change exists or not; (14) a video frame at the time is redundant information, and the operation of writing video frame data into the screen recording file is stopped temporally; (15) desktop video frame data are obtained through a Qemu interface and written into the screen recording file of this time, in other words, the video frame data are continually written into the screen recording file; (16) screen recording is ended, and the screen recording file of this time is saved. By means of the cloud terminal screen recording method, the operation of a user on a terminal can be all recorded for safety audit, meanwhile, the storage space can be saved, and the screen recording efficiency can be improved.

Description

technical field [0001] The present invention relates to a screen recording method, in particular to a cloud terminal screen recording method. Background technique [0002] With the development of cloud computing and virtualization technology, desktop cloud technology is becoming more and more mature. The use of desktop cloud reduces the IT cost investment of enterprises, and has strengthened the maintainability and security of the system, which is green and environmentally friendly. With the widespread deployment of desktop cloud, especially in confidential enterprises, security is getting more and more attention. For security audit, it is necessary to record and monitor the cloud desktop. [0003] Currently, screen recording methods based on various remote desktop protocols have two disadvantages: [0004] First, the screen recording behavior is performed on the terminal device, and then the screen recording file is transmitted to the server. The disadvantage of this is ...
