| description | In order to carry on copyright protection and security verification of color QR code,the digital image chaos encryption technology and digital watermarking technology were respectively researched.Firstly,an improved image chaos encryption algorithm was proposed as a preprocessing step of digital watermarking algorithm.Then a color QR code digital watermarking algorithm was designed based on discrete wavelet transform and matrix singular value decomposition.Finally,the feasibility of the algorithm was verified by experiments.The results show that the proposed method has good resistance to JPEG compression,noise attack and cropping attack. |
