Abstract: A DaubeChies wavelet digital image watermarking algorithm based on scrambling was proposed in this paper. DaubeChies wavelet as basic wavelet was chosen in this paper. So it could make full use of multi-resolution character and deal with the low-frequency and high-frequency in grades. This was different from previous watermarking algorithms. On this basis, combining encryption feature of affine transform to scramble watermarking image and construct DaubeChies wavelet watermarking algorithm. The simulation demonstrated that the algorithm was not only robust to filter, mosaic, noise and other attacks, but also had a good balance between invisibility and confidentiality. Thus, this increased the security of information.
