Two high capacity text steganography schemes based on color coding
This work addresses the problem of secure data hiding in text for applications like secure communication, though it appears incremental as it builds directly on existing ideas.
The paper tackles text steganography by proposing two schemes based on color coding to hide secret messages in cover texts, achieving better hiding capacity compared to a prior scheme by Aruna Malik et al.
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.
