The stego-image quality is further estimated in terms of the peak signal-to-noise ratio (PSNR) and embedding capacity/payload. Table 1 gives the results of the proposed scheme in terms of embedding capacity and PSNR value. We have obtained high acceptable PSNR values for stego-images with a high embedding capacity of secret messages.

The result will be that when the image is reconstructed by a standard decoder, image quality will be only slightly impacted, An encrypted stego image is an image that has been embedded
