QR Code Steganography

QR codes, also known as matrix codes, are basically two dimensional barcodes embedded with data that can be decoded quickly for information. In this work, we present a novel use of QR codes. We show that QR codes can be used for covert communication using steganography. We also show in complete detail how to build QR code symbols with a hidden payload and how to extract this hidden information ...
