摘要

文字隱藏是將重要訊息資料隱藏至一段遮蔽文字中，得到偽裝文字，藉由偽裝文字外觀的自然性，使一般使用者無法直接察覺到秘密訊息的存在，達到安全傳送隱藏訊息的技術。在聊天室的應用上，本論文提出一個基於中文同音字為基礎的文字隱藏技術，利用聊天室允許傳送錯誤文字的特性，特別是中文同音錯別字(Homophone Errors)，根據常用的中文同音字設計一個編碼簿，作為文字隱藏編碼的根據。實驗結果顯示，本研究所提的方法可以有效的在聊天文字中嵌入秘密訊息，所傳送的偽裝訊息，也不易被察覺。在聊天室等應用上，所提方法可提供一個即時且安全的秘密通訊工具。

Hidden text message data is important to a shelter to hide the text, the text has been disguised, camouflaged by the natural appearance of the text, so that users can not directly detect the existence of secret messages, hidden messages sent to security technology. In the chat room applications, this paper presents a homophone for the Chinese-based text hiding technique based on the use of text chat rooms allow the transmission error characteristics, especially the Chinese homophone spelling (Homophone Errors), used according to design a Chinese homophone codebook, as hidden text encoding basis. The results show that this study provides an effective way to embed a secret in the chat text messages, sent messages of camouflage, not readily detectable. In the chat room application, the proposed method can provide a confidential and secure real-time communication tools.
