Desktop virtualization-based watermark realization method and device

Abstract

The invention discloses a desktop virtualization-based watermark realization method and a desktop virtualization-based watermark realization device. The method comprises the following steps of: triggering a starting instruction of a virtual desktop to transmit a configuration rule to a client; after the virtual desktop is normally started, starting a desktop watermark process according to the configuration rule; monitoring an operation state of the desktop watermark process; and logging out the virtual desktop to prevent the access to a server through the virtual desktop when the desktop watermark process operates abnormally. The method and the device have the beneficial effects that a watermark is added on the virtualized desktop and the added watermark is displayed on the top layer of the virtualized desktop; and further, the evidence for a doer who discloses information through approaches such as photographing or image pick-up of the contents of the desktop can be found, and the protection grade of the information can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for realizing a watermark based on desktop virtualization. Background technique [0002] Desktop virtualization technology refers to the virtualization of computer desktops to achieve the security and flexibility of desktop use; virtualized desktops such as commonly used virtual desktops (also known as secure desktops) have become a tool to prevent data leakage and ensure data security. It is a common technical solution, but when users access confidential files on the server through virtual desktops, they can still easily save the text or picture information on the virtual desktops by taking photos or videos, which will cause confidential data leakage, the source of leaks But there is no way to track it.

[0002] Desktop virtualization technology refers to the virtualization of computer desktops to achieve the security and flexibility of desktop use; virtualized desktops such as commonly used virtual desktops (also known as secure desktops) have become a tool to prevent data leakage and ensure data security. It is a common technical solution, but when users access confidential files on the server through virtual desktops, they can still easily save the text or picture information on the virtual desktops by taking photos or videos, which will cause confidential data leakage, the source of leaks but no trace

[0003] At present, watermark technology can be added to documents in specific formats, such as documents in word, excel, and PDF formats, to determine the source of documents and information, but there is no method for adding watermarks to virtualized desktops.
