Analogy of various DNA based security algorithms using cryptography and steganography

In today's era Information technology is growing day by day. The rate of information storage and transformation is growing day by day. So information security is becoming more important. Everyone wants to protect its information from attackers and hackers. To provide security to information there are various algorithms of traditional cryptography and steganography. New field DNA cryptography emerges to provide security to data store in DNA. The DNA cryptography uses the Bio-Molecular computational abilities of DNA. In this paper authors compare the various DNA cryptographic algorithms on certain key and important parameters. These parameters would also help the future researchers to design or improve the DNA storage techniques for secure data storage in more efficient and reliable manner. The authors also explain the different biological and arithmetic operators use in the DNA cryptographic algorithms.
