A novel data hiding scheme is proposedbased on encoding and substitution. Both the cover media and the secure information are encoded to achieve the substitution. Simulating the genetic codon table in molecular biology,arandom grouping algorithm is proposed to generate the pseudo genetic codon table, which regulates the substitution. The cover media is encoded into a DNA codon like sequence. Then, the codons of thecover media in the form of DNA codon sequence are substituted withother codons in the same group according to the pseudo genetic codon table. The secureinformation in the arbitrary N-nary form decides which codon is selected during every substitution. Due to the random construction of pseudo genetic codon table, encryption is incorporated in the data hiding process. Analysis and experiments havetested the validity and efficiency of the scheme.
