While the computational capabilities of deoxyribonucleic acid (DNA) are now fairly known, with the building of DNA computers which utilize DNA and other sub-cellular molecules as input and output, little seems to have been investigated on the information security properties of DNA in computer science and information technology terms. The author investigated DNA as a hypothetical information hiding molecule, which employs the principles of steganography to obscure information that might be of importance to a hypothetical attacker. By employing the combinations and permutations of bases in DNA nucleotide sequences as substitutes for an English letter, the author shows that in addition to the computational capabilities of DNA, it also mimics basic information hiding and information security protocol.
Key words: Deoxyribonucleic acid (DNA) computing, information hiding, steganography, information security, biotechnology, bioinformatics.
