Image Steganography in QR Codes Using Secure Techniques with Two-Level Discrete Wavelet Transform and DES Encryption

Abstract

Steganography was the art & science of writing secret messages(SM) in a way which no one else is, separately from sender and the intended recipient, it knows there is hidden message. Propose Algorithm are hybrid S system that relies on Discrete Wavelet Transform (DWT) and Quick Response (QR-code) .This method involves decoding encoding operations in case of domain.  Text message are hidden in QR code image where the QR code image are hidden in DWT. It method has been well performed & additional security is provided to information. This paper focuses the concept of an image stenographic approach capable of embedding encrypted secret messages using the Quick Response Code (QRC) code for the image data The 2-level DWT domain & LSB is used to embed QR code while embedding method is protected by the DES Algorithm. In addition, the standard features of QRC have been overcome by encryption (E), making the technique more secure. The goal of such a paper is to develop the image S approach with a high level of security & high level of non-perceptibility. The relationship among security & method capacity was strengthened special encoding of the QRC prior to the embedding method. The effectiveness of A proposed approach are evaluated by (PSNR) Peak Signal-to-Noise Ratio  & Mean Square Error (MSE) & results achieved were compared with other S tools. It work has been compared to other methods. A proposed method has achieved a high level of safety & more imperceptibility.
