Wave transformation and 4 *4 block Schur decomposition of the low frequency part are carried out. Then the binary values are obtained by using the stability of the coefficient difference of the subblock unitary matrix.
The watermark information is embedded into the carrier QR code adaptively. Finally, the watermark information is extracted by scanning the watermark QR code. At the same time, the algorithm achieves blind extraction. Results The algorithm can resist the attack of print and scan, and can resist Gaussian noise, salt and pepper noise, speckle noise, Poisson noise.
JPEG attacks such as compression have strong robustness. Conclusion the algorithm has strong resistance to print scanning and can be widely used in digital products.
