Abstract

The invention relates to a watermark processing device, method and system for a display device. The watermark processing device comprises a watermark generation module, a watermark processing module and a signal output module. The watermark generation module is used for generating watermark data containing required information. The watermark processing module is used for performing superposition processing on the watermark data and image data acquired from an image generation device to generate watermark image data. The signal output module is used for outputting the watermark image data to the display device. According to the invention, due to the fact that video processing and watermark embedding are completed in independent equipment different from a computer, a large amount of development work for adapting to different systems is not needed, and meanwhile the problem that the system is attacked due to incompatibility with an operating system is avoided.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a watermark processing device, method and system. Background technique [0002] With the popularization of various smart devices, shooting and recording screens has become very convenient. Therefore, the asset security of personal, enterprise and institutional office computers is facing severe challenges. Regarding the leakage of secrets caused by shooting or recording screens, relevant units It is not easy to detect and cannot be traced, which will bring inestimable losses to individuals, enterprises and institutions that have leaked secrets. Therefore, a stable and reliable anti-disclosure traceability system becomes more and more important. [0003] At present, it is generally adopted to add a watermarking application program compatible with the version of the operating system running on the terminal device to the operating system of the terminal de...
