Information hiding quality prediction model training method and device, equipment and storage medium

The invention provides a training method and device of an information hiding quality prediction model, equipment and a storage medium, and relates to the technical field of information security. The training method of the information hiding quality prediction model comprises the following steps: collecting a plurality of original images; adding to-be-hidden information into the original image to obtain a target image; constructing a training sample set according to the peak signal-to-noise ratio (PSNR) of the target image and the size value and the brightness value of the original image; the training sample set is substituted into a preset algorithm model, an information hiding quality prediction model is obtained through training, and the information hiding quality prediction model is used for recognizing the image information hiding quality. The information hiding quality prediction model trained by the model training method does not need to depend on the target image after the to-be-hidden information is h
