摘要:
研究了文本信息隐藏技术,提出~种改进的改变文本载体字符字体的隐藏算法。该算法首先把秘密文本信息中的字符转换为ASCII码,再把ASCII码转化16位二进制码,然后把16位二进制码的高八位和低八位转换为十进制数,用RSA加密法将十进制数加密,最后把十进制码再转换成16位二进制码并利用伪随机置换法把秘密信息代码嵌入到载体文本中。嵌入时选取两种字体,若代码为“1”,载体文本的字体不变,若为“0”则改为一种与原字体相近的字体。通过这些处理手段大大提高了单纯的基于特征编码的信息隐藏技术的安全性
Abstract:
An improved algorithm of text information hiding based on font is proposed in this paper. First of all, the characters in the secret text are changed into ACSII codes. Secondly, ASCII codes are changed into 16 bit - birary codes. Then, the higher 8 bits and lower 8 bits in 16 - binary codes are transformed into decimal codes, which are encrypted by RSA algorithm. Finally, switch the encrypted deeimal to 16 - bit binary again, and hide them into the rover text with faking random replacing rule. Chose two kinds of similar font, if the code is 1, the font of character keeps the original style, and if the code is 0, the font of character switches to other one, which is quite similar to the original one, As the result, the algorithm is safer than just using eharaeteristie- based information hiding algorithm
