目前資訊技術日益發達,資訊交流頻繁,因此安全的傳遞資訊非常重要,常見傳遞方法有數位浮水印、密碼學等方法,近年來,許多人開始探討視覺機密分享方法,視覺機密分享的特色是不需要電腦即可進行解碼,在分存數量不足的情況下不易被破解。但是,視覺機密分享的解碼影像品質相對於影像分享方法差,且分存不易管理,導致管理人員的不便和困難。本論文提出文字型視覺機密分享方法,不同於傳統視覺密碼學單純對影像進行處理,提出方法是對純文字檔案進行分享,將文字檔案列印在投影片後,進行疊合可以出現機密資訊,同樣的方法可以將視覺分享的特性,套用在文字型視覺分享上,因為文字檔案的特性,本文方法已經具有友善視覺分享的特性,且又有安全與不易攻擊之特性。
With the fast development of computer science and technology, the circulations and exchanges of information have created challenges to data security while the common methods applied are digital water marking and cryptography. 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.
