Data hiding based on contrast mapping using dna medium

Abstract EN

Recently, biological techniques become more and more popular, as they are applied to many kinds of applications, authentication protocols, biochemistry, and cryptography.

One of the most interesting biology techniques is deoxyribo nucleic acid and using it in such domains.

Hiding secret data in deoxyribo nucleic acid becomes an important and interesting research topic.

Some researchers hide the secret data in transcribed deoxyribo nucleic acid, translated ribo nucleic acid regions, or active coding segments where it doesn't mention to modify the original sequence, but others hide data in non-transcribed deoxyribo nucleic acid, non-translated ribo nucleic acid regions, or active coding segments.

Unfortunately, these schemes either alter the functionalities or modify the original deoxyribo nucleic acid sequences.

As a result, how to embed the secret data into the deoxyribo nucleic acid sequence without altering the functionalities and to have the original deoxyribo nucleic acid sequence be able to be retrieved is worthy of investigating.

This paper applies reversible information hiding scheme on deoxyribo nucleic acid sequence by using the reversible contrast mapping technique.

The reversible property makes the secret data hidden in anywhere in deoxyribo nucleic acid without altering the functionalities because the original deoxyribo nucleic acid sequence can be recovered exactly in our scheme.
