DNA Watermarking Using Codon Postfix Technique.

Abstract

DNA watermarking is a data hiding technique that aims to protect the copyright of DNA sequences and ensures the security of private genetic information. In this paper, we proposed a novel DNA watermarking technique that can be used to embed binary bits into real DNA sequences. The proposed technique mutates the codon postfix according to the embedded bit. Our method was tested for a sample set of DNA sequences and the extracted bits showed robustness against mutation. Furthermore, the proposed DNA watermarking method proved to be secured, undetectable, resistance, and preservative to biological functions.
