Abstract :
In this paper, we propose a novel way called Data Hiding Self Conjugate Error Diffusion to hide invisible patterns in a single error diffused halftone image. The hidden patterns would appear on the halftone image when the halftone image is folded or overlaps with its own rotated version. Simulation results show that the halftone images have good visual quality and the hidden pattern is visible clearly.
