This paper presents a copyright protection scheme based on discrete cosine transform (DCT) and secret sharing techniques. The proposed scheme first utilizes the features of a host image, obtained by performing the DCT on the host image, to generate a master share. Then, the master share is used together with a binary watermark to create an ownership share by employing the secret sharing technique. To verify the rightful ownership of the host image, the hidden watermark can be revealed by using the master and ownership shares. Experimental results demonstrate that the proposed scheme accomplishes satisfactory robustness against several common image processing attacks.
