As a result of explosive development of the Internet, digital contents can be convenient and fast exchanged on the Internet. Hence, how to protect important digital contents from being stolen or modified has become an important issue. In this paper, an optimal ownership verification scheme for image contents based on using both the pinned field of the protected image and the genetic algorithm is proposed. The pinned field explores the texture information of the protected image and can be used to enhance the robustness of the watermark. The genetic algorithm is then used to optimize the similarity between the texture information and the protected image. Experimental results show that the proposed scheme can survive under different signal processing and geometric transformation attacks.
