Text steganography method based on modified run length encoding

Abstract EN

Data hiding (Steganography) is a method used for data security purpose and to protect the data during its transmission.

Steganography is used to hide the communication between two parties by embedding a secret message inside another cover (audio, text, image or video).

In this paper a new text Steganography method is proposed that based on a parser and the ASCII of non-printed characters to hide the secret information in the English cover text after coding the secret message and compression it using modified Run Length Encoding method (RLE).

The proposed method achieved a high capacity ratio for Steganography (five times more than the cover text length) when compared with other methods, and provides a 1.0 transparency by depending on some of the similarity measures of Steganography.
