| Abstract [eng] |
DNA Steganography is a relatively new entry in the Steganography field and even DNA Storage is relatively new as data storage scientists are still figuring out a fast and efficient method to store data in DNA molecule which has relatively large storage capacities in comparison current day commercial magnetic or solid-state storage devices like magnetic hard drive or solid state drives, hence there is a need to evaluate a futuristic Steganography technology like DNA Steganography with the traditional established Steganography techniques like DCT. In this scientific paper, three major Steganographic algorithms have been analysed, one DWT based Egypt, DCT and DNA Substitution which are based on some complex mathematical properties of encoding data. The mathematical properties of these algorithms are used to store data in the medium and in this paper the efficiency of each algorithm to store secret data is evaluated by determining the PSNR value for each algorithm is determined to evaluate the performance of the algorithms. After some basic experimental testing, the experiment shows significant difference in the signal storage quality and computational complexity of each algorithm and that there is a need to choose a specific algorithm based on the Steganographic application. There are some other implications which can be derived from the analysis of the experimental data and that is there is extensive corruption of the data embedded into the video stream which is why there is a need to record the same data into each frame of the video to maintain redundancy. DNA Steganography still has a long way to go before it can compete commercially with traditional Steganographic algorithms. Thus, the goal of this research paper which is to evaluate the performance of each Steganography algorithm like DCT, Egypt and DNA Substitution has been achieved and a statistical basis to differentiate the performance of each Steganographic algorithm has been established. |
