Data Hiding on Text Using Big-5 Code
Jun-Chou Chuang, Yu‐Chen Hu · 2012
This paper presents a text hiding scheme using Big-5 code. Some text-hiding schemes embed secret information at between-word and between-character by adding tabs or spaces. Liu et al. proposed a Chinese text data hiding scheme to divide the Chinese character into left and right parts for data embedding. However, the adjusted spaces or divided characters of between-word may look like strange and it may expose the risk of security. Therefore, we intend to design a text hiding scheme using Big-5 code. The secret is hidden into spaces between-word and between-character of a cover text by placing a Big-5 code either 20 or 7F. The visual quality of the stego-document is the same as the original document and therefore reducing the suspicious of attention by hackers. Experimental results show that the visual quality of the proposed scheme achieves good results and feasibility.
