基于字符特征与同义词替换结合的文本隐写方法
Text Steganography Based on Character Features and Synonym Replacement
摘要
Abstract
Steganography by modification such as synonym substitution modifies the original text,so it is easy to be discovered because of the contextual mismatch.However,the coverless steganography,for example steganography by generation,cannot make the sentence fluent,because it is limited by the natural language comprehension technology.In order to balance the security and usability,a text steganography method based on the combination of character features and synonym replacement was proposed.The binary string of the secret is represented by the characters' features,and the location information is represented by the synonym substitution.It is showed that this method is easy to be implement,and security of this steganography method can be enhanced by the transformations of character features.Furthermore,this method is flexible and makes better in its capacity of concealment.The method designs a high capacity scheme,which can be combined with instant messaging.关键词
