Due to the rapid development of Internet, digital multimedia data are frequently transported on the Internet. Hence, how to protect important data from being stolen or modified has become an important issue. Digital watermarking can protect digital rights by embedding owner watermarks into the digital data, so the owner can declaim his ownership and intellectual property. In this paper, we propose a new watermarking method for image copyright protection by using the pinned field of the pinned sine transform of the protected image. The pinned field explores the texture information of the images and can be used to enhance the robustness of the watermark. Experimental results show that the proposed method can survive under different signal processing and geometric transformation attacks. Furthermore, our method is lossless because it does not modify the content of the protected image, and it does not need the original protected image during the authentication procedure.
