In this paper, we propose a novel mechanism for QR code security anti-counterfeit based on the fusion of visual secret sharing (VSS) and QR code (called VSSQR scheme), which can greatly improve the security of QR code payment. Due to different application scenarios, the background security anti-counterfeit application and the prospects security anti-counterfeit application are shown for QR code payment authentication. The basic idea of the two applications can be characterized as follows. First, two QR code shares that contain the information of the merchant can be generated based on VSSQR scheme with an original secret image. Second, the secret image can be revealed by stacking two QR code shares to obtain the original information. Finally, whether the stacking result is the same as the original secret image or not can determine the authenticity of QR code share used for payment. The analyses show the security of our method. The applications are conducted to show the effectiveness and practicability.
本文提出了一种基于视觉秘密共享（VSS）和 QR 码融合的 QR 码安全防伪新机制（称为 VSSQR 方案），可以极大地提高 QR 码支付的安全性。由于不同的应用场景，针对 QR 码支付认证，展示了背景安全防伪应用和前景安全防伪应用。这两种应用的基本思想可以概括为：首先，基于 VSSQR 方案，使用原始秘密图像生成两个包含商户信息的 QR 码共享；其次，通过堆叠两个 QR 码共享来揭示秘密图像，以获取原始信息；最后，根据堆叠结果是否与原始秘密图像相同来确定用于支付的 QR 码共享的真实性。分析表明了我们方法的安全性。通过应用实例展示了其有效性和实用性。
