摘要
针对网络聊天中存在的安全隐患和利用文本及表情符号进行隐蔽通信的需求,提出了基于文本和表情符号的信息隐藏算法.该算法以字节为单位,依据表情符号的位置、前后空格的数量和字符数的奇偶性等来进行隐蔽信息的嵌入和提取.实验结果证明,该方法对聊天内容不仅没有任何外观的影响,而且可以起到隐蔽通信的目的,具有隐蔽性高、容量大和方便实用等特点.
Referring to the potential hazard of safety in chatting on line and the demand of text and emoticons to covert communication, an algorithm is proposed of hiding information based on texts and emoticons. The algorithm in bytes for the unit is on the basis of the emoticon position and the amount of spaces before and after, the parity of the number of characters, etc, to perform the embedding and extracting of the concealed information. The experimental results show that the method, which has no visual impact on the content of chatting and can achieve the purpose of hiding information, has many characteristics, such as high concealment, large capacity, convenience and practicability.
