Abstract :
In this paper, we propose a method to hide invisible patterns in color error diffused halftone images. The hidden pattern is embedded in different color components. The hidden patterns would be revealed when the watermarked color halftone images are under Boolean operation or overlaid. Simulation results show that the watermarked color halftone images have good visual quality and the hidden pattern is visible clearly.
