Research on the Application of Visual Cryptography in Cultural and Creative Artworks

Abstract

Visual cryptography has a good application prospect in halftone information hiding and anti-counterfeiting. This paper mainly studies the application of this technology in office partition and window painting, decorative calligraphy and painting, etc. In order to achieve a visual isolation and calligraphy and painting presentation function of information hiding and presentation method. Visual encryption, halftone image processing, digital modulation and information coding techniques are applied. Visual encryption A and its open-key image B are generated by the algorithm, and then image B is modulated by halftone calligraphy image. The half-tone calligraphy image information is image B. When image A and carrier image B are superimposed together, the compatibility of halftone noise isolation image and half-tone calligraphy image can be realized by position adjustment. The results show that the method achieves good compatibility in information hiding and artistic expression.
