摘　　要：目的解决目前半色调加网信息隐藏技术中显隐效果不佳的问题。方法通过分析显隐菲林片的显隐机理,从微观几何角度出发,建立隐藏信息与显隐菲林片之间的几何匹配关系。结果隐藏图文与显隐菲林片之间匹配关系的建立,使二者能够实现一对一的精确匹配,模拟实验的显隐效果清晰。结论为半色调加网的信息隐藏与显隐提供了参考方法。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.
