使用公開搜尋引擎搜尋私人加密文件

Abstract

我們相信，最好的加密方法，就是讓別人不覺得這文件是已經加密過的。 利用中文詞語的特性，以及文法，我們希望找出一套方法，使得在加密後，依然是可以閱讀的文章，但是意義已經大不相同，進而達到加密的目的。 本論文的目的將設計與實作一個隱藏中文訊息的方法，使得這些加密過的文件，能夠再公開搜尋引擎上搜索到，卻不會被發現到這些文件原本的意義，也能夠利用公開的空間，儲存這些文件。

We believed, the best encryption is lets others not think this document has already encrypted. Using Chinese words characteristic, grammar, we hope to discover a methods that is still readable after encryption. But the meaning has already entirely different. Then we can achieves the goal of encryption. The paper will design and implement a system for Chinese information hiding. Let those encrypted document can search by the public search engine. But others cannot understand the original meaning of these documents. And also we can use public space to store these documents.
