Abstract

The invention discloses a content self-adaptive screen watermark display method. The method comprises: a screen watermark program monitoring computer operation behaviors of a user in real time; acquiring a current running program of the system and related contents in a program display window; searching the key content obtained by the operations, and extracting keywords/characters contained in thecontent; the screen watermarking program further determining the current running program and the attribute to which the related content in the display window belongs according to the contained keyword/word information; when the computer is in a system desktop or runs a browser program, displaying text watermarking on the screen; when the computer runs office software, displaying dot matrix watermarks on a screen; when the computer opens the picture or plays the video, displaying the two-dimensional code watermark on the screen. According to the method, the software running safety is improved,the influence of the screen watermark on the display content can be reduced, and the visual experience of a user is improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a method for generating a screen watermark in the content security technology, in particular to a content-adaptive screen watermark display method. Background technique [0002] With the development of computer technology and network technology, more and more data are stored in the computer. When the electronic form of data brings convenience to people in storage and transmission, it also causes data security problems. In recent years, incidents of enterprises, institutions and personal data being leaked by taking photos, videos, and screen captures have emerged one after another. When it is found that the data has been illegally leaked, but the source of the leak cannot be traced in time, it has long been a problem that has plagued people. The emergence of screen watermarks can solve this problem very well. By presenting a visible watermark on the screen, the risk of...
