FPGA Implementation of Vigenere Cipher Method Based on Colour Image Steganography

Abstract

This paper proposes a new Stenography method employing quantization table using FPGA .In this method new Vigenere Cipher is been used for encryption and decryption of the secret message. The color transformation techniques can be used to increase the modified coefficients so as to have good capacity and stego-size results. The capacity which is the amount of information embedded in color images increases, with the number of modified quantized DWT coefficients.
