Advanced Encryption Standard Algorithm in Digital Watermark Images
Abstract
Abundant amount of information was produced, stored, and shared digitally. This increase as well as validating the info of ownership information has been digitally watermarked.
The process of embedding confidential data into an original image is known as "watermarking" an image. In order to guarantee the system's security, Advanced Encryption Standard (AES) encrypt the logo image in this proposed paper.
The normalize root mean square error (NRMSE), peak to signal ratio (PSNR), root mean square (RMSE), mean square error (MSE), and structural similarity (SSIM) are utilized for evaluating the performance of embedding and decrypting watermark images.
The developments and findings from measurements supported the AES encryption method's reliability, and the histogram demonstrated the encrypted logo image's pixels' excellent distribution and showed how different the encrypted image is from the watermark image in terms of uniformity and bit depth. This indicates that the bit interleaves encryption image affected the level values and pixel positions, and the extracted and original logo images' excellent structural similarity (SSIM) scores are around 0.9.
