DNA Watermarking Using Codon Postfix Technique

Area of Science:

• Bioinformatics
• Molecular Biology
• Cryptography

Background:

• DNA sequences are crucial for genetic information, necessitating robust copyright protection and security measures.
• Existing data hiding techniques may not be suitable for the unique characteristics of DNA sequences.
• The need for secure and undetectable methods for embedding information within biological data is growing.

Purpose of the Study:

• To propose a novel DNA watermarking technique for embedding binary data into DNA sequences.
• To ensure the security, undetectability, and robustness of embedded information against biological alterations.
• To develop a method that preserves the natural biological functions of DNA sequences.

Main Methods:

• A novel DNA watermarking technique was developed.
• The method involves mutating the codon postfix of DNA sequences to embed binary bits.
• The technique was tested on a sample set of DNA sequences.

Main Results:

• The embedded bits were successfully extracted from the DNA sequences.
• The extracted bits demonstrated robustness against various forms of mutation.
• The watermarking method proved to be secure, undetectable, resistant to manipulation, and preservative to biological functions.

Conclusions:

• The proposed DNA watermarking technique offers a secure and effective solution for protecting DNA sequence copyright and private genetic information.
• The method's robustness against mutations and preservation of biological functions make it suitable for real-world applications.
• This technique advances the field of data hiding within biological sequences.
