  Text steganography is a mechanism of hiding secret text message inside
another text as a covering message. In this paper, we propose a text
steganographic scheme based on color coding. This include two different
methods: the first based on permutation, and the second based on numeration
systems. Given a secret message and a cover text, the proposed schemes embed
the secret message in the cover text by making it colored. The stego-text is
then sent to the receiver by mail. After experiments, the results obtained show
that our models performs a better hiding process in terms of hiding capacity as
compared to the scheme of Aruna Malik et al. in which our idea is based.
