Abstract Information hiding is a technique that hides secret messages in some carrier during transmission or storage. Carriers in common use include image, audio, video, text documents and so on. Since there is little redundancy in text documents, particularly in plain text documents, information hiding based on plain text documents is much more challenging. Previous algorithms based on plain text documents are all based on a single plain text segment. Therefore, there are many inherent limitations in security of them. In this paper, a novel information hiding algorithm based on double text segments is proposed. The algorithm can enhance the concealment and security of information hiding greatly by choosing a proper hiding form out of many ones and scattering information to places. In addition, the algorithm is so flexible that it can be modified or adjusted according to the certain application scene to fit the practical requirements better.
