Printed halftone image embedded with specific information can be used for protection and authentication of the print. A novel information hiding algorithm for printing halftone image was designed, which transform original watermarking information into Fresnel hologram; the Fresnel hologram was then embedded into the host image as watermarking information with discrete wavelet transform algorithm to realize information hiding. The algorithm used unique hologram to enhance the robustness of watermark. The experimental results showed that the algorithm has better robustness to image halftone attack.
