| 摘 要： | 提出了一种新的LSB隐藏方法,根据待嵌载体图像像素值的奇偶性和嵌入信息的内容,选择像素值加1或加2的嵌入方式,使得SPA(sample pair analysis)攻击的假设条件在嵌入前后保持平衡,致使SPA攻击失效。在使用该方法嵌入率达到100%时,SPA攻击的估计值仍然小于判决门限。实验不仅验证了新方法抵抗SPA攻击的能力,也验证了新方法可以抵抗RS等检测。新方法嵌入方式简单,且无需在嵌入后再做附加处理,便于实现。

| Abstract: | A new LSB steganography method is proposed.According to the parity of carrier's image pixel to be embedded and the content of embedded information,the embedded way of the pixel adding 1 or 2 is chosen to make the hypothesis of SPA(sample pair analysis) attack keep balance before or after the embedding,causing SPA attack disable.When the proposed algorithm is used to make the embedding rate reaching 100%,the estimated value of the SPA attack is still smaller than judge threshold.Experimental results validate... |
