Covert Communication via the QR Code Image by a Data Hiding Technique Based on Module Shape Adjustments
A novel data hiding method for covert communication via the QR code image based on adjustments of the shapes of the QR code modules using image processing techniques is proposed. A module block consisting of two module pairs is taken as the unit for message-bit embedding by adjusting the vertical an...
