Abstract: The technique of watermarking is used to safeguard the copyright protection and used to prove the proprietorship of certain images, documents, audio and video files. This paper presents a new scheme where the final digital image is created after embedding one watermark inside another watermark (dual watermark), scrambled the image to safeguard from intruders and then embedded into the main digital image. The dual watermark mechanism improves the capacity of the data to be watermarked and more importantly the dual watermarked image is encrypted using symmetrical encryption algorithm (IB algorithm) an improved version of the blowfish algorithm to increase the security and makes it harder for the intruders to crack the watermark.
