QR Code是一個二維的單色圖像條碼，近年來許許多多關於QR Code隱藏方法相繼提出，這些方法是利用編碼文字以及修改QR Code本身的結構所提出的資料隱藏方法。為了儲存更多資料，美國微軟公司(Microsoft)利用色彩來儲存更多資訊而開發出「彩色條碼(High Capacity Color Barcode)」。同樣地，在不干擾一般機器解讀QR Code裡的訊息之情況，利用色彩可使QR Code擁有更多一般QR Code讀取器解碼不出來的訊息。本篇論文中我們提出具有色彩藏匿秘密訊息特性之QR Code，並使用EMD(Exploiting Modification Direction)與MSD(Modified Signed Digit)技術增加安全性，進而，使用CRC32與MD5這兩種驗證以確保訊息完整性。

Quick Response (QR) Code is a monochrome and widely used matrix barcode with the increasing population of smart phones. In recent years, the QR Code steganography methods have been proposed that encoding the text or change the QR Code’s structure to hide the secret message. In order to store more information the High Capacity Color Barcode (HCCB) have been proposed by Microsoft which the HCCB can use an eight-, four-, or two-color (black-and-white) palette to store more and more data. Similarly, the case does not interfere with the general QR Code Reader to decode the message, the use of color can make QR Code have more data message. In this paper, we proposed color of QR Code to hide the secret message, and using Exploiting Modification Direction (EMD) and Modified Signed Digit (MSD) to increase the security, and secondly, using CRC32 and MD5 authentication modes to ensure message integrity.
