In accordance with the structural features of QR barcode, a text blind watermarking algorithm is proposed in this paper. The algorithm is that the Hill 2 Encryption and BCH error correction encoding are used in the watermark pro-processing and then the watermark information is embedded in the rows and columns of QR barcode by using structural fine-tuning method. The QR barcode security and confidentiality are effectively improved by combining two-dimensional barcode with digital watermark technology. © 2011 Springer-Verlag Berlin Heidelberg.
