Abstract

The invention discloses a watermark processing method and device. The watermark processing method comprises the steps of determining a region image corresponding to a watermark image in a webpage image; generating a regional watermark image by using the regional image and the watermark image; and replacing the regional image in the webpage image with the regional watermark image. According to themethod and the device, the regional watermark image can be generated through the watermark image and the regional image, so that an invisible effect of the watermark image can be realized, a joint attack on a webpage can be resisted, and automatic processing on the webpage is realized.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a watermark processing method and device thereof. Background technique [0002] As an important means to prevent data leakage, digital watermarking technology can play a role in data traceability and copyright protection. At present, there have been many research results on digital watermarking technology for image, audio, video and other media. As the webpage is the carrier of disseminating information, more and more information on the webpage appears on the content of the webpage, and the security of the webpage content has gradually become a hot issue. In order to prevent the webpage from being used by direct screenshots, digital watermarking technology can be used to perform watermark embedding processing on the webpage. [0003] In the prior art, after the original image corresponding to the webpage is obtained, the watermark image can be added manually by mean...
