摘　　要：当前,大多数信息都以文本文档的方式进行存储与传输,这种文本文档存储与传输的普遍性使得基于文本文档的信息隐藏方法具有重要的研究价值。然而当前流行的基于文本的信息隐藏方案具有鲁棒性较差、语义杂乱无章且肉眼轻易就可以分辨、嵌入率低等问题。为解决以上问题,利用ASCII码中的不可见字符的独特性,提出针对于英文文本的信息隐藏算法,该算法是通过对英文文本中的空格进行处理来达到隐藏效果。实验表明,所提出的信息隐藏方案是可行、可靠、安全以及高效的。At present,most of the information are stored and transmitted through the plan-text,the universal storage and communication of such text documents pose an important value on studying the text document-based information hiding approaches. However,current prevailing text-based information hiding schemes are facing many problems,such as poor robustness,semantic untidy,low embedding rate and easily being penetrated by unaided eyes. In order to solve these problems,this paper puts forward an information hiding algorithm for English text by using the distinctiveness of invisible characters in ASCII codes. The algorithm reaches the hiding effect by processing the spaces in English texts. Experiments show that the hiding algorithm proposed in the paper is feasible,reliable,safe and efficient.
