Research on information hiding and recognition technology of halftone prints based on mobile phone

This paper studies the method of embedding printing quantum information in the printed image and identifying whether the image carries hidden information by comparing the eigenvalues of the gray-level co-occurrence matrix of the image. The anti-counterfeiting performance of the halftone hidden image after the embedded printed quantum information is analyzed through a combination of subjective and objective methods. The results show that the anti-counterfeiting performance of the image is not affected after the embedded printed quantum information. The encrypted image and the unencrypted image are in the ASM energy, entropy. The difference between differential entropy is obvious. The halftone information hiding algorithm proposed in this paper provides a new idea for realizing the display of halftone hidden information on the mobile terminal.
