 本文提出一個高容量的二元影像資訊隱藏方法，資訊隱藏用於二元影像的困難處在於二元影像只有黑與白兩種顏色，只能在容量與不易被察覺之間作抉擇，而高容量是本篇論文著重的地方。基於安全性考量，本文的方法在嵌入前會先使用擬亂數產生器(Pseudo Random Number Generator)將機密資料打亂。掩護影像先分割成不重疊的4×4區塊，每一個4×4區塊再分割成四個重疊的3×3子區塊，機密資料將嵌入在每個子區塊中。基於嵌入容量的考量，本方法只略過全黑或全白的4×4區塊，略過這些不適合嵌入的區塊，可以避免嵌入後的影像輕易被辨別出來。所以機密資料只嵌入在非全黑或全白的4×4區塊中，該區塊可以劃分成四個重疊的3×3子區塊，分別利用第一個子區塊中間與左上的像素、第二個子區塊中間與右上的像素、第三個子區塊中間與左下的像素、第四個子區塊中間與右下的像素作互斥(Exclusive-OR)邏輯運算，每一個3×3子區塊可以嵌入一個位元資訊。萃取的方法很簡單，只要將每個3×3子區塊中間的像素與角落的像素作互斥邏輯運算，如果互斥邏輯運算所得到的結果為1，代表此子區塊內嵌入的位元為1，否則為0。收集所有萃取出來的位元資訊，經過擬亂數產生器打亂回覆原始的排列順序，就可完整萃取出機密資料。由實驗結果顯示，本文提出的方法保有高嵌入容量且不易被察覺。
 In this paper we propose a high capacity data hiding method working on binary images. Hiding data in a binary image is more difficult since it has only black or white two colors. It is a trade off between capacity and imperception. We focus on the capacity in this paper. In general we shuffle the secret data by a pseudo-random number generator before hiding to support more secure. We divide the cover image, which the secret data will be concealed, into non-overlapping four by four sub-blocks. Then we repartition each four by four sub-block into four overlapping three by three sub-blocks. Due to consider embedding more data in the cover image, we only skip the all blacks or all whites in four by four sub-blocks. It avoids to observed easily and prevent perceptible simply. We embed the secret data in each four by four sub-block if it is not all the same color. We consider all four three by three sub-block to check the XOR between upper left and center, upper right and center, bottom left and center or bottom right and center, then embed one bit in each three by three sub-block. The extraction way is simply to test the XOR between the four corner pixels and centers of each three by three sub-block. If XOR equal 1, the embedding bit is 1, otherwise is 0. All embedding bits are collected and shuffled back to the original order. The secret data are extracted completely. The experimental results show that the method provides the large embedding capacity and keeps imperceptible.
