In order to improve the security performance of the information stored in Quick Response (QR) code, this paper introduces an improved RC4 algorithm which can be used in the encryption of QR code. We add the self-error detection stage into fault induction attack resistence and combine Chaos with enhanced pseudo-randomness in the stage of PRGA. The experimental results show that the new method proposed in this paper has several advantages in security and reliability.
