Abstract :Transferring secret message is a real issue and is the need of the time. Steganography deals with concealing secret message in the image whereas cryptography is about changing the message into a distorted form, so that it is prevalent from hacker entry. Combining both the steganographic and cryptographic methodologies will yield a secure and sophisticated method for interchanging the secret messages within the transmitter and receiver. An original Discrete Wavelet Transform – Singular Value Decomposition (DWT-SVD) based stenographic methodology is accordance. Quick Response (QR) secret message payload prototypes the interchange of the singular-quantity of DWT blocks. In this document, a secure materials model is accordance by combining cryptography and steganography. QR secret messages are engagement for encoding the encrypted message. A nested image steganography is performed with QR secret messages on a suitable cover image. The suggested process has a potential to be engagement in communicating secret materials. This method has high Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and Root Mean Square Error (RMSE) survived chi-square quantity with 100% message recovery.
