Abstract |
|
|
| Steganography provides unconventional solutions to protect communication as well as copyright of intellectual property.
In this paper, we propose a steganographic method that exploits some characteristics of the Deoxyribonucleic Acid (DNA) for hiding
other types of digital content. The proposed work is an extension to [1], as it provides a solution to the problem that the sender and
the receiver have to secretly communicate both the stego-DNA and the reference sequence. Communicating such information could be
suspicious and reveals the secrecy of the steganographic channel itself.
Thus, the proposed hiding method is implemented in two main stages: the first one hides the secret message into some reference
DNA sequence using a generic substitution technique. The next phase employs a self embedding algorithm that randomly inserts the
stego-DNA sequence into the reference one. In this way, the extraction process can be done blindly and the communicating parties
don’t actually have to exchange anything in advance but the secret key. Furthermore, a DNA-based playfair ciphering is applied on the
secret data before embedding in order to increase the security of the hiding algorithm. When compared with other hiding methods, the
proposed method showed an outstanding performance providing high security and embedding capacity. |
