The paper proposes a new data hiding method based on deoxyribonucleic acid (DNA) coding, using the Word document as carrier. The plain message becomes a cipher sequence after being encoded to a DNA sequence and encrypted by the addition operation. The cipher sequence is attached to a random DNA primer sequence and circularly shifted for finite times, then hide the whole sequence into a Word document through substituting each character¡¯s color. The plaintext can be extracted according to the keys, and the key space is large enough to resist brute force attacks. Experimental results show the feasibility of the scheme.
