摘要：Cryptography is the science of protecting information by transforming data into formats that cannot be recognized by unauthorized users. Steganography is the science of hiding information using different media such as image, audio, video, text, and deoxyribonucleic acid (DNA) sequence. The DNA-based steganography is a newly discovered information security technology characterized by high capacity, high randomization, and low modification rate that leads to increased security. There are various DNA-based methods for hiding information.. In this paper, we compared three DNA-based techniques (substitution, insertion, and complementary) in terms of its capacity, cracking property, Bit Per Nucleotide (BPN), and payload. The selected algorithms combine DNA-based steganography and cryptography techniques. The results show that the substitution technique offers the best BPN for short secret messages and offers the best imperceptibility feature. We also found that both the substitution and the complementary method have a threshold BPN. On the other hand, the insertion method does not have a threshold BPN and it is more difficult to crack.
