Image Steganography is the process of embedding secret data in images such that its existence cannot be detected by others apart from sender and the receiver. The present work focus on combination of cryptography and steganography to secure the data while transmitting over the network. This paper presents image steganography using Block based Discrete Wavelet transform for embedding of encoded secret message using Quick Response Code (QR) code into image while embedding process is further protected by Advanced Encryption Standard (AES) cipher algorithm. Efficiency of the proposed method was measured by Peak Signal-to-Noise Ratio (PSNR) .
