摘要 根据载体图像和嵌入量的大小,利用随机函数确定出嵌入字节的位置,使嵌入信息分布均匀;研究了异或运算的性质,结合位平面的特点,通过位的异或运算,实现秘密信息嵌入;对嵌入的字节最多只需修改一位,可在该字节中同时嵌入两位秘密信息,提高了秘密信息嵌入量,并能无损还原。理论分析和实验结果证明了算法的有效性。 This paper presents a new method to ascertain the position of embedding bytes according to the size of cover image, embedding capacity and random function. The embedding information is distributed evenly. The secret information is hiding though the properties of XOR operation and the features of bit planes. The algorithm makes the two secret information bits embed into a pixel, but only need change one bit at most. It can enhance the embedding capacity and the secret information can be recovered with no change The experimental results show that this method is available and efficient.
