The aim of this study was to solve the problem of unsatisfactory appearing effect in information hiding technology based on halftone screening. The mechanism of information appearing film was analyzed to establish the matching relation between hidden information and information appearing film through microgeometry. The hidden information and information appearing film match exactly according to the matching relation, and the result of the simulation experiment proved that the appearing effect was improved. Taken together, this study provides a reference method for information hiding and appearing based on halftone screening by establishing the matching relation between hidden information and information appearing film.
