Steganography is the art and science of secret communication, aiming to conceal the existence of a communication, which has been used in military, and perhaps terrorists. Steganography in the modern day sense of the word usually refers to information or a file that has been concealed inside a digital Picture, Video or Audio file. In steganography, the actual information is not maintained in its original format and thereby it is converted into an alternative equivalent multimedia file like image, video or audio, which in turn is being hidden within another object. Information Security is becoming an inseparable part of Data Communication. In order to address this Information Security, Steganography plays an important role. The digital media steganalysis is divided into three domains, which are image steganalysis, audio steganalysis, and video steganalysis. DNA sequences possess some interesting properties, which can be utilized to hide data. This paper is a review of the recent steganography techniques and utilization of DNA sequence appeared in the literature.
