it should be noted that, after the data content is acquired, the content is generated into a content image consistent with the visual effect of the data content, for example, if the data content is text data, the font color, the paragraph format, and the like in the generated content image are not changed in the visual effect; if the data content is image data, the original image is directly used as the content image.
And generating the encrypted image according to the data content image and preset interference content as follows.
After the content image is generated, the content image is encrypted by superimposing a preset interference content on the content image, where the preset interference content may be a watermark, a data content with a changed font color, a data content with a changed partial font size, a data content with a changed partial paragraph format, or the like.
As described in step S130 above, the data content in the target area of the website is replaced by the encrypted image.
