原文摘要：
Steganography is not a new concept of secret subject, the war of as early as the Rome times of Greece go to the modern age can see many examples in there willing be.With the secret the method of the delivers the intelligence, and acquire the advantage on the intelligence. In electronically times of the present, the medium that deliver also be become by traditional article of the entity signal of the electronics.The special feature of this research is to do not need the ratio of the file of the diagram of the primitive to can immediately take out to hiding the message. Method is applied spread spectrum steganography technique, selecting by examinations the part position and join the error corrected code and interleaving, enhance the robustness of steganography. Testing with the JPEG compress, random channel error and cut with image etc. Take the diagram of Lena as an example, its result compresses quality as in the JPEG 80, compress magnification as 16 times, pick to hide message the bit error rate below 6% ;The channel error rate at 15%, bit error rate of the hiding message below 13% ;Cutting the image 1/2 , bit error rate of the hiding message below 13% .

資訊隱藏不是一個新概念的秘密主題，早在希臘羅馬時代的戰爭到現代的戰爭中就可以看到很多例子，用秘密的方法的提供情報，並獲得優勢的情報。在現今電子化的時代，傳輸媒介也將由傳統的實體物件成為現實的電子設備。本研究是不需要與原始圖檔比對就可以立即拿出來隱藏信息。方法是應用於展頻資訊隱藏技術，選取部份隱藏位置並加入錯誤糾正編碼和交錯器，增強資訊隱藏的隱秘性，以JPEG壓縮破壞、亂數通道破壞與影像切斷等方法測試。就以Lena圖為例，其結果在JPEG壓縮品質為80，壓縮倍率為 16倍，選擇隱藏信息的錯誤率低於 6％，亂數通道的破壞率為 15％，位元錯誤率低於 13％；切割1 / 2的圖像後，位元錯誤率低於 13％。
