An Efficient Use of Toffoli Quantum Gate for Boosting the Embedding Capacity in DNA Sequence

While hiding data in DNA sequence, the steganograpy schemes try to increase the embedding payload, enhance the security of implanted data, protect the stego expansion and preserve the biological characteristics of DNA sequence. In this research, we have proposed a new data hiding method where the scheme implants secrets in DNA sequence using a classical Toffoli quantum gate mechanism. The proposed scheme implants 4-bits of information per nucleotide. Experimental results demonstrate that the proposed scheme achieves massive improvement over the others which is 4 to 12-times higher than the competing schemes.
