摘　　要：二维码是一种快速扫描和解码的矩阵式条形码,具有高密度储存信息的能力。然而二维码的信息容易被未经授权的访问者读取或篡改。因此,研究提出一种面向全自动打贴码设备的二维码信息隐写模型,通过秘密信息嵌入算法与提取算法达到对信息的保护。研究选择H等级二维码进行实验,结果表明,研究提出的隐写模型中嵌入算法使嵌入信息容量能力提升50.4%~164.4%,且绝对嵌入率超过30%,PSNR值平均为53.4 dB,SSIM值平均为0.937。而模型中的提取算法能够有效保证隐写二维码信息的真实性。在烟草公司实际应用中,隐写模型的加入使得烟草公司的假冒产品数量降低24.8%。研究建立的二维码信息隐写模型在保护二维码信息安全和完整性方面具有重要意义,能够促进信息加密技术的发展。QR codes are matrix-style barcodes that allow for rapid scanning and decoding,with the capability to store a high density of information.However,QR code information is vulnerable to unauthorized access and tampering.Therefore,this research presents a QR code steganography model tailored for fully automatic labeling devices,using secret information embedding and extraction algorithms to protect information.The research results show that the proposed steganography model enhances information embedding capacity by 50.4%to 164.4%,achieving an absolute embedding rate of over 30%.The PSNR values average 53.4dB,and the SSIM values average 0.937.In practical applications at a tobacco company,the incorporation of the steganography model leads to a 10.4%increase in data accuracy,a 31.5%increase in customer satisfaction,while reducing counterfeit product prevalence to 9.4%and increasing counterfeit product detection rates to 90.4%.The established QR code steganography model holds significant importance in safeguarding the security and integrity of QR code information and can foster the development of information encryption technologies.
