A Unique Cipher Mechanism Integrating Steganography with Traditional Cryptography

Now a days most of the information is transmitted over the network whether personnel or professional and concept of electronic money is also in trend, bank transaction or online shopping are more in trend then before so we need to make the network more secure. Traditional cryptographic mechanisms are more vulnerable to attacks now as they are well known to attackers and many new forms of attacks are being developed exploiting their loop holes so we need to design new methods of encrypting or hiding data to make transactions more secure. Here we have developed a cipher mechanism where we can hide a gray scale image in RGB component of a colored image in random manner which adds an element of uncertainty and original and watermarked images are almost similar so it’s very difficult to predict any information hidden in the image.
