“…A modified PI method along with MSB over hides LSB code is available in [12]. Several review articles are available in [22][23][24][25] which gives a clear picture about information hiding through OFDM, CDMA, Data Security in Firmware and FP GA. Its counter action is steganalysis which broadly cover the secret data presence, identifying the length of the secret or simply suppressing the secret [26][27][28][29][30].…”

with each and everyone trying to transport their data encryption. Steganography then took over the power, by hiding through the public data networks, today's data communication the message in a cover object may be video, Audio and Image [ infrastructure has become more generic that there is absolutely 3], keeping the message indestructibly safe from malicious no discrimination between different types of data in the hackers, from eyeing into the message. The cover in which the 'transport' plane of communication. This generic nature or the message is hidden can either be a text, image, audio or video lack of customization leads to the easy sniffing of data by file.

The other classification in camouflages the existence of a security mechanism to protect the information hiding is watermarking [6] and its objective is data, making it less inquisitive for the rogue parties.
