Research on Digital Watermarking Algorithm Based on QR Barcode
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.
