AbstractThe technique of information hiding is one of information security techniques, which works on embedding information on media in such a way that avoid bringing suspicion of discovering transmission between two ends.
In this paper, a modified algorithm is suggested depending on two principles: double information hiding and multiple watermarking. The first principle is represented by cryptography and steganography in a way that each method work separately from the other to ensure a secure content that embedded in the message. While the second principle depends on multiple watermarking represented by images with secret key in a gray image to achieve authentication and accuracy of sending data. Cryptography is used to protect binary image (original watermarking) by using a secret key and embedding more than watermarking (binary and gray images) inside cover file (color image) by using signature (data) that have been taken from the cover file and adopted in the spatial domain for hiding data.
