Verification of Secret Information in Image Steganography

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 among terrorists. Steganography, in the modern day sense of the word, usually refers to the 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. 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. Deoxyribo Nucleic Acid (DNA) sequences possess some interesting properties, which can be utilised to hide data. This paper proposed steganography technique for hiding and retrieving text.
