Method and device for processing screen watermark

Abstract

Embodiments of the invention provide a screen watermark processing method and apparatus. The method comprises the steps of obtaining a process list, which is running and needs to be protected, in a system; obtaining a watermark module, creating one or more top-layer full-screen watermark windows according to the watermark module, and hiding the top-layer full-screen watermark windows; and enumerating all current top-layer windows in system windows, obtaining top-layer visible windows according to the current top-layer windows, and if it is judged that any of processes corresponding to the top-layer visible windows is in the process list, displaying the top-layer full-screen watermark windows. The apparatus is used for executing the method. According to the method and the apparatus, the top-layer full-screen watermark windows are created; the processes corresponding to the top-layer visible windows are enumerated; and if it is judged that the process corresponding to the current top-layer visible window is in the process list needed to be protected, the top-layer full-screen watermark windows are displayed, so that the use of a global message hook is avoided and the system operation efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer security, in particular to a screen watermark processing method and device. Background technique [0002] With the widespread application of electronic document encryption, more and more companies pay attention to data security. At present, the protection methods for electronic document security include: using transparent encryption technology or active encryption technology. [0003] However, no matter which of the above encryption methods is used, there is a common problem, that is, it is impossible to trace the user's responsibility for taking pictures of the encrypted documents that have been opened, resulting in random data leakage. In order to solve the above problems, the prior art protects the security of documents by adding watermarks on the screen, and most of the existing screen watermarking technologies are based on cross-process window subclassing, or throug...

Problems solved by technology

However, both of the above two technologies need to mount a global message hook on the system, that is, if there are n processes that need to be protected on the PC side, the traditional implementation scheme needs to create n transparent watermark windows, and the system needs to send messages for these n windows. Distribution and processing, reducing the operating efficiency of the entire system
