    摘要: Based on the principles of the visual cryptography and the law of large numbers, the unexpanded shares are generated during the processes of embedding and verifying the hidden watermark. The watermark embedding is done in the frequency domain, which can be decoded by the human visual system (HVS) without the necessity of any complicated computation and the help of the original image. Experimental results indicated that our method had a good robustness on darken, lighten, blur, sharpen, noise, distort, jitter, joint photographic experts group (JPEG) compression, and crop attacks.
