摘要：The goal of steganography is to conceal the existence of information hidden in cover medium (most commonly digital images, text, audio, video files) during information transmission. DNA (Deoxyribo Nueclic Acid) as cover medium is one of the possible alternatives that are currently being investigated. DNA is a chain of nucleotides (Adenine (A), Guanine (G) Cytosine (C) and Thymine (T)) wherein the nucleotide taken as triplets forms a codon. Codons are translated to amino acids using the genetic code to form proteins. Mutation occurs when a change in the nucleotide of a codon affect the amino acid formed. Most of the existing DNA based steganography communication caused mutation thereby disrupting the biological function of cover DNA. In this paper, we elucidate a novel algorithm to randomly assign the nucleotides of the synthesized DNA strand of the transformed secret information in putative protein coding region of eukaryotic DNA, avoiding mutation.
