Abstract :As digital communication continues to expand, protecting the privacy and security of transmitted images has become increasingly crucial. Image hiding addresses this issue by concealing secret images within cover images. Most methods typically embed a secret image into a single cover image, which poses a risk if that cover image falls into the wrong hands. To address this issue, we propose a secret image hiding method that employs multiple cover images. The secret image is distributed across four cover images, while the fifth cover image is used to embed the perceptual hash values of the stego images in the proposed method. These hashes serve to accurately determine the correct sequence order of stego images during the extraction phase, especially in cases where file names or transmission order have been altered, ensuring proper extraction. Experimental results indicate that the proposed method achieves high visual quality of stego images, with an average PSNR of 44.9626 dB, and enables lossless recovery of the secret image.
