AI Technical Summary

Technical Problem

In the prior art, screen shooting traceability methods have problems such as complex watermark images, insufficient hidden information, and high difficulty in recovering information during traceability. Especially after the widespread popularity of smartphones, traditional watermark technology is difficult to effectively track and restore information.

Method used

By encoding the watermark information, the watermark information sequence is embedded in the image using R channel, G channel and B channel of RGB, and combined with perspective distortion correction and color block segmentation technology, the watermark information is obtained and traced.

Benefits of technology

It improves the concealment of watermark images and information hiding capacity, reduces the complexity of watermark images, enhances the success rate of information recovery, solves the distortion problems caused by lighting, lens distortion, etc., and ensures that the user's visual quality is not affected.

Abstract

The invention discloses a screen shooting traceability method, device and equipment and a readable storage medium, which are applied to the field of computer software, and comprise the following steps: encoding watermark information to obtain a watermark information sequence; embedding the watermark information sequence into the image through an R channel, a G channel and a B channel of RGB (Red, Green, Blue) to obtain an image with a watermark; and acquiring the shot image with the watermark image, and tracing to obtain watermark information based on the shot image. According to the method, the watermark is generated by using the RGB channel of the single pixel image, so that the visual concealment of the watermark image is improved, the difficulty in perceiving of human eye recognition is ensured, and the visual quality of a user is not influenced; the watermark embedding position is not influenced by an original image carrier, and watermark information can be hidden in any area of the image; and the watermark information recovery success rate is high.
