摘　　要：秘密分享作为隐私保护的重要手段,近来在云计算、物联网等领域迅猛发展.二维码作为当下极为流行的信息载体,其使用频率远超传统图像,因此秘密分享技术在二维码上的应用前景广阔.然而,由于二维码常以纸质形式呈现,容易遭受污渍沾染或破坏;同时,隐写二维码在传输过程中可能遭到攻击者篡改.这些情况必然导致隐写二维码中出现误码,而现有研究方案无力实现无损重构秘密信息.鉴于此,本文提出一种基于扩展汉明码的二维码秘密分享方案.该方案不但确保了载体的高嵌入容量,还实现了隐写二维码的可纠错性,能够准确检测并纠正隐写二维码中的误码,进而恢复秘密信息.理论分析与实验充分证明了该方案的有效性和实用性.Secret sharing,as a crucial method for privacy protection,has seen rapid development in fields such as cloud computing and the Internet of Things in recent years.As a very popular information cover at present,Quick Response Code(QR Code)is used far more frequently than traditional images,so the application of secret sharing in QR Code has highly promising.However,because the QR Code is often presented in paper form,it is easy to be stained or damaged;At the same time,stego-QR codes may be tampered by attackers during transmission.These issues will inevitably lead to bit errors in stego-QR code,and the existing research schemes are unable to recover the secret losslessly.To address this,this paper proposes a QR Code secret sharing scheme based on Extended Hamming Code.This scheme not only ensures high embedding capacity but also implements error correction capability of stego-QR Codes,which can accurately detect and correct bit errors in the stego-QR Code,and then recover the secret.Both theoretical analysis and experimental results demonstrate the effectiveness and practicality of this scheme.
