摘要
针对QR码的结构特征,提出一种QR码数字水印嵌入算法,即根据条码容量自适应调节水印大小,并利用结构微调法在条码的行列中分别嵌入水印信息的方法。将二维条码和数字水印技术相结合有效提高QR条码的安全性和保密性。
In accordance with the structural features of QR barcode,a digital watermarking algorithm is proposed.The algorithm is that the size of watermarking is adjusted according to barcode capacity and then the watermarking information is embedded in ranks of QR barcode by using structural tuning method.Combining two-dimensional barcode with digital watermark technology improves the security and confidentiality of QR barcode.
