A Researcher at the college of administration and economics Mr. Mohamed Leith Talal published a paper in a Canadian Journal (Design Engineering) entitled: (Digital Watermark as a way to include data in digital content to protect them from forgery and theft). The research addressed the use of the chaotic algorithm to create a digital watermark, and the inclusion of chaotic watermark images in the host image, both of which are color images. The research aim was to increase reliability and protection against attacks and penetration using PSNR, NC, and MSE measures, where the results achieved have proven that the watermark is strong and reliable.
