(7,4)汉明码的二维码信息隐藏算法

Data Hiding Method for QR Code based on Hamming Code

为了解决因专利开放使用二维码传递敏感信息时,二维码中敏感信息被任意通用扫描器读取,进而泄漏用户隐私的问题,提出一种基于(7,4)汉明码的二维码信息隐藏算法。该算法在保证二维码有效的前提下,把秘密信息嵌入至二维码的内容码字中。一个有效且有意义的二维码可大大降低被窃取的风险,进而保护用户的隐私。实验结果表明,本算法简单有效,所生成的带有秘密信息的二维码具有较好的鲁棒性。

Due to the patent opening,the sensitive information in the QR code can be read by any general scanner,and then the privacy of users can be disclosed.In order to solve this problem,this paper proposes a two-dimensional code data hiding algorithm based on(7,4)hamming code.The algorithm embeds the secret information into the content codeword of the QR code on the premise that the QR code is still valid.An effective and meaningful QR code can greatly reduces the risk of theft and protect the privacy of users.Experimental results show that the algorithm is simple and effective,and the generated two-dimensional code with secret information has good robustness.
