In traditional information hiding algorithms, embedding rate and image visual quality are mutually restricted, so the relationship between them cannot be balanced. Therefore, in this paper, a high fidelity scheme combining reversible information hiding method and irreversible information hiding method is proposed, which takes advantage of the high embedding rate of the irreversible information hiding method and the high peak signal-to-noise ratio (PSNR) of the reversible information hiding method in the aspect of image visual quality, so as to embed more secret information with less distortion. In addition, the scheme can also find the relative optimal embedding rate, the balance point between the restored image PSNR and the PSNR containing the dense image according to the specific application scene, so as to adapt to different application requirements. Experimental results show that the proposed scheme has higher embedding capacity and better image visual quality than the existing schemes.
