Abstract:
Steganography is a tool which allows the data for transmission by concealing secret information in a tremendously growing
network. In this paper, a novel technique quick response method (QRM) is proposed for the purpose of encryption and
decryption. Existing system uses side match vector quantization (SMVQ) technique which has some challenges such as security
issues and performance issues. To handle the security and performance issues, the proposed system uses two methods, namely,
quick response method and shifting method. In the proposed system, encoding part calculates the performance for capacity,
PSNR (peak signal-to-noise ratio), MSE (mean square error), and SSIM (structural similarity index method), and the decoding
part calculates the performance of MSE (mean square error) and PSNR (peak signal-to-noise ratio). The shifting method is
used to increase the data hiding capacity. In this system, the encryption part embeds the secret image using steganography and
the decryption part extracts the original image. By analyzing and comparing the proposed system with the existing system, it is
proved that the system proposed was much better than the existing systems.
