  • Method and system for generating watermark on the basis of graphic, terminal, and medium
    Patent number: 11704764
    Abstract: The invention provides a method and system for generating a watermark on the basis of graphic, a terminal, and a medium. The method includes acquiring a watermark image and at least one watermark unit image; acquiring watermark encryption information; determining the distribution information of the watermark unit images in the watermark image according to the watermark encryption information and a preset encryption model, the distribution information comprising imaging regions of the watermark unit images in the watermark image; and overlaying each watermark unit image into a corresponding imaging region in the watermark image to generate the watermark. The watermark encryption information has a one-to-one corresponding relationship with the distribution information of the watermark unit images in the watermark image, and the corresponding relationship can be defined by a user so that others cannot crack the watermark without knowing the encryption model, thereby improving the watermark cracking difficulty.
