Hiding Messages Based on DNA Sequence and Recombinant DNA Technique

Data hiding unnoticeably conceals message to prevent such message from being leaked to the existing media so as to ensure the confidentiality of the relevant information, which plays an important role in DNA cryptography. A data hiding model based on DNA sequence and recombinant DNA technique has been proposed to transmit information securely. According to the proposed model, a message can be hidden on a DNA sequence by using a single mapping rule table, and further concealed in DNA plasmid by recombinant DNA technique. The recombined DNA can be concealed in organisms and screened by selectable markers. This single mapping mechanism can improve the embedding capacity. The way to hide message in organisms is more flexible than that in micro-point of DNA. The relevant experimental results and security analysis show that the cracking probability of the model is negligible, which can ensure the security of information.
