Steganography in DNA Sequence on the Level of Amino acids

The increasing advancements in bioinformatics have recently attracted many pieces of research in the field of cryptography and steganography. We are proposing a steganographic algorithm that aims at preserving the properties of a DNA sequence (carrier) based on the distribution of DNA codons upon amino acids in the standard genetic code table. The algorithm hides a secret message inside a DNA sequence while preserving its biological properties and another algorithm extracts back the secret message using the secret key. The paper is considered a way to minimize the gap between DNA computing and Digital computing and proves this relation through applications. We have compared our algorithm to other related DNA-based steganographic algorithms and proved that our algorithm is robust, has advanced utilization storage and invulnerable to several types of possible attacks.
