Abstract
AbstractThis article introduces a new technique to hide text‐in‐text messages. The proposed mechanism uses the structure of omega network to hide and extract secret messages. The generation of secret message is made as follows, take every letter from the original message, use the omega network to generate two related letters from the selected letter, and finally search the dictionary for a suitable English cover word to hide the generated two letters. In order to increase the chance of find a suitable words, the generated two letters need not to be adjacent in the cover word. As a result, the white‐space steganography is used in order to hide the position of the two letters in the selected cover word. The experiments show that the proposed mechanism gives a better execution time and better cover words than the current similar mechanisms especially when we are trying to hide long text messages.
