Hybrid, randomized and high capacity conservative mutations DNA-based steganography for large sized data

“…These amino acids are further converted to binary and embedded within cover image using 2-3-3 embedding technique and transmitted through the communication channel to the receiver. Ghada Hamed et al, [16] proposed, an algorithm integrating between cryptography and steganography to achieve well secured and high capacity, that algorithm depends on molecular biology concepts. That algorithm is achieved by two phases.…”

The main purpose of the data encryption process is the difficulty of understanding the content of the message with the difficulty of detecting the encryption mechanism. Therefore, in this paper, we proposed a new model of encryption based on the idea of encrypting text messages and gray images using amino acid chains. Amino acids are distinguished by being a series of alphabets represented by 20 characters and do not have a specific length. The main idea of this paper is to get an amino acid chain that contained encrypted message. To develop this model, we construct an artificial lookup table to encrypt any character of message to the amino acid chain, after that applying encryption process. The proposed model was applied on different kinds and sizes of messages, which proved the success of the main idea of the research, which is obtained amino acid chains with encrypted messages. The proposed model appears efficient in real time of encryption and extraction process compared with known methods. In the end, we compared the amino acids that we extract on the process of encrypting with internationally known amino acids and we found a similar ratio, which proves that the proposed model is effective in terms of increasing ambiguity of the encrypted message.

“…However, in 1994, Leonard Adleman demonstrated that by applying stepby-step DNA biochemical reactions, a process like a computer science algorithm, the directed Hamiltonian path problem could be solved efficiently due to the large number of simultaneous DNA reactions [5]. Since then, DNA computing has become an eye-catching branch in computer science [2,3,6,7,8,9,10,11,12]. In 1999, Clelland et al encoded a secret message as a DNA fragment (the secret-message DNA) and hid it among many other "junk" DNA fragments.…”

“…www.ijacsa.thesai.org There are three classical methods to hide data into DNA sequences, namely the insertion method, the complementary pair method, and the substitution method [4]. Several revisions of these methods were proposed, but the fundamental techniques keep the same [7,9,11]. All the methods require a binary coding rule to convert between binary digits and nucleotide bases (A, C, G, T).…”

Different from cryptography which encodes data into an incomprehensible format difficult to decrypt, steganography hides the trace of data and therefore minimizes attention to the hidden data. To hide data, a carrier body must be utilized. In addition to the traditional data carriers including images, audios, and videos, DNA emerges as another promising data carrier due to its high capacity and complexity. Currently, DNA based steganography can be practiced with either biological DNA substances or digital DNA sequences. In this article, we present a digital DNA steganography approach that utilizes the CRISPR-Cas9 off-target editing such that the secret message is fragmented into multiple sgRNA homologous sequences in the genome. Retrieval of the hidden message mimics the Cas9 offtarget detection process which can be accelerated by computer software. The feasibility of this approach is analyzed, and practical concerns are discussed.
