Abstract
With the wide application of quick response (QR) codes, its security has been paid more and more attention. There are many steganography schemes to embed the secret message into QR codes, which can be used in terrorist activities, spread viruses, etc. However, there is currently no effective scheme for detecting stego QR code. This paper divides the spatial QR code-based steganography schemes into three categories and then proposes a steganalysis method for QR codes. The method includes detecting stegao codes and recovering pure QR codes, which is realized by the code regeneration, module comparison, and embedded information filtering operations. Our method can perfectly distinguish the stego code and block the transmission of embedded information for the spatial QR code-based steganography schemes. Theoretical analysis and experiments show that the proposed method is feasible, universal, and robust.
