Abstract

A new technique for hiding multimedia data in text, called the Hiding in Text (HIT) technique, is introduced. The HIT technique can transform any type of media represented by a long binary string into innocuous text that follows correct grammatical rules. This technique divides English words into types where each word can appear in any number of types. For each type, there is a dictionary, which maps words to binary codes. Marker types are special types whose words do not repeat in any other type. Each generated sentence must include at least one word from the marker type. In the hiding phase, a binary string is input to the HIT encoding algorithm, which then selects sentence templates at random. The output is a set of English sentences according to the selected templates and the dictionaries of types. In the retrieving phase, the HIT technique uses the position of the marker word to identify the template used to build each sentence. The proposed technique greatly improves the efficiency and the security features of previous solutions. Examples for hiding text and image information in a cover text are given to illustrate the HIT technique.
