摘要Digital watermarking is a technique for the protection of intellectual property rights. In this study a novel ownership protection scheme based on visual cryptography and the law of large numbers is proposed, where 2 phases, namely an ownership construction phase and an ownership authentication phase, each with 3 steps, are designated to illustrate how it works. In our scheme, two pixels at a time are selected randomly from the host image, then compared with the other and the results determine the corresponding content of the shares. The law of large numbers is employed to ensure the random distribution of half-black-and-half-white shares, which satisfies the demand needed for security in visual cryptography. The proposed method enjoys several advantages over conventional methods such as it does not to alter the host image, it can identify the ownership without the help of the original host image, and it allows multiple watermarks or larger watermarks to be registered in a smaller host image. Finally, experimental results are given to illustrate the robustness of our scheme against several common attacks.
