Implementation of Chaotic-Based Hybrid Method to Provide Double Layer Protection

Abstract

In the modern era, Internet is the most widely used transmission medium. While transmitting any secret information through any public channel, then that may be hacked in between. So to send data to the receiver without any kind of damage, here we have proposed a hybrid method by using both the cryptography and steganography technique. The secret message is first encrypted by using chaotic neural network. For encrypting data, we used CNN because of its random nature which is very challenging for hackers to know about the secret information. The secret key decides the position to hide the encrypted data. Only authorized users share the secret key. The receiver finds the original message by using secret key and then decryption is performed. Our experiment shows that PSNR of our method is very high as the technique modifies lesser number of bits. This method provides good security and less distortion to original image.
