PIXEL LEVEL REVERSIBLE DATA HIDING USING TWO LEVEL ENCRYPTIONS REVIEW

At some level of transmission of data is not secure and safe so to make the data more secure there are many methods to follow, Cryptography and Steganography are the one among them. These uses the data as an information and make them into a cipher form or just hide the existence of the data in other forms of the data then the data can be transferred in a protected way. The combinational use of both Cryptography and Steganography helps in providing the better security than the individual work of their own. The Cryptographic algorithms are used to provide two-level encryptions by converting the Original Text data into a cipher form of an integer valves with a Private Secret key whereas the Steganography converts the cipher integer values into RGB values and then modify a single pixel in each frames of the video which is selected by the user using the encryption. At the receiver’s end the RGB values are obtained by the selected pixels then the integer value is obtained by these RGB values then the integer values obtained is decrypted in the first frame to the secret key, then other frames are retrieved and the integers obtained here are decrypted with the help of secret key, then the decrypted values are the ASCII values which are converted into its characters and then appended to the original message and then the message is
