QR Code (QUICK RESPONCE) are basically embedded with data that can be easily decoded, OR code have substantial role in mobile application like online payment, adhar card etc... In every camera enabled smartphone can scan QR code. The QR code are 2D barcodes that encode text information. In recent year’s security of information have become big concern in the internet, so the information hiding has become an important issue. In steganography, Steganography hides the data in a medium suchas text file, image, audio, video etc., and restrain the very existence of the message in the medium from a third party .In this paper ithides the message inside a cover image. The main approaches to steganography must provide two attributes: High security against the dissimilar assaults called steganalysis and second is compression. In this paper a latest approach is proposed for secret communication by combining the concept of steganography and QR codes. In the suggested method include two phase: (1) Encrypting the text message by a QR code encoder and creating a QR code, (2) Hiding the secret image inside the generated QR code. This proposed approach has to be employed in communicating confidential information.
