In recent years scientists have begun to investigate the techniques of visual secret sharing and its feature is messages can be decoded without computer application and the difficulty of being decoded while messages are shared. However, with visual secret sharing the quality of images after being decoded is lower than the one via visual share, so that it causes difficulties for managements and this study will present discussions about the related issues. Thus, this study proposed a text form visual sharing scheme. Different from traditional visual sharing scheme which handle with image, the proposed method is share to text file. Secret information revealed after users stack two or more transparencies which print texts. The advantages of proposed method includes not only the advantages of traditional visual sharing method, but also have the characteristic of friendly visual sharing method.
