Screen watermark generation method and device, electronic equipment and storage medium

Abstract

The invention relates to the field of security protection, and provides a screen watermark generation method, which comprises the following steps of: firstly, creating a watermark service file under a preset directory to form a watermark daemon thread, automatically starting the watermark daemon thread based on a startup password, and creating a communication channel between the watermark daemon thread and a client; and acquiring a key document and a storage identifier from a client through a communication channel to enable a watermark daemon thread to call a watermark display subprogram, and then analyzing the key document and the storage identifier to acquire a key and a target address to enable the watermark display subprogram to display a watermark on a client screen corresponding to the target address according to the key. Therefore, the watermark display subprogram is prevented from being maliciously damaged when the watermark is generated, and the overall safety of watermark generation is improved.

Description

technical field [0001] The invention relates to the field of security protection, and relates to a method for generating a watermark, in particular to a method for generating a screen watermark, a device, electronic equipment and a computer-readable storage medium. Background technique [0002] With the development of terminal technology, the current computer terminals are equipped with a screenshot function, which can capture pictures on the display screen. At the same time, smart phones now generally have the function of taking high-definition photos. If the content accessed by the user is important or sensitive information within the organization , Unauthorized screenshots or photos are very likely to cause information security incidents such as information leakage. [0003] The screen watermark design is a functional identification designed to prevent information viewers from maliciously taking screenshots or taking pictures, so as to set watermark protection on the scre...

AI Technical Summary

Problems solved by technology

The existing screen watermark technology is generally a screen watermark generation program developed based on the Microsoft Windows operating system, but on the LINUX operating system, especially on the domestic operating system UOS, there is no screen watermark generation program and its self-protection mechanism. Or access and browse sensitive data information on the UOS operating system, which may lead to leakage of important information
