Steganography is the art of covered or hidden writing. The main purpose of steganography is covert communication-to hide the existence of a message from a third party. Steganography is generally used to hide important information in a visible media mostly an image. A good approach to steganography must provide two attributes: high security against the different attacks called steganalysis, which is nothing but a technique used for detecting hidden information using steganography method and second is compression. Image compression not only reduces storage but also benefits transmission. In this paper the image steganography is achieved with enhanced security due to QR code and compression using DWT transform, without affecting the actual cover image due to addition of secret information which is in form of QR codes. The process for embedding the QR codes has been carried out using Embedding and Extraction algorithm which insures secure and fast transmission of stego image. These results validate the practical feasibility of the proposed method for security applications.
