Representation of the correlation between codon frequency distribution produced via our watermarking algorithm and the initial codon distribution of the host genome (y-axis). The watermarking algorithm generates a signature indistinguishable from the rest of the genome. The x-axis here is 100 randomly generated binary signatures of length 1000 mapped to the codon frequency distribution of the individual codons in E. coli
