A Review on DNA based Cryptography for Data hiding

In today's world, securing data is becoming one of the main issues, the elaboration of the fusion of cryptography and steganography are contemplating as the sphere of on-going research. This can be gain by cryptography, steganography, and fusion of these two, where message firstly encoding using any cryptography techniques and then conceal into any cover medium using steganography techniques. Biological structure of DNA is used as the cover medium due to high storage capacity, simple encoding method, massive parallelism and randomness DNA cryptography can be used in identification card and tickets. Currently work in this field is still in the developmental stage and a lot of investigation is required to reach a fully-fledged stage. This paper provides a review of the existing method of DNA based cryptography
