In this work, we have created a new approach for chaotic grayscale image watermarking, this approach is manifested in inserting a mark in the form of a cryptic image into a cover image by an invisible method. The algorithm of this approach uses two mathematical tools which are DWT and DCT. It is also based on the chaotic beta function for the encryption of the inserted mark. The results acquired from the different analyses indicate that the proposed method has high sensitivity and security compared to other methods.
