- W3129303911 abstract "The rapid development of multimedia technology has brought huge challenges regarding the security of multimedia content. Digital watermarking is a widely-used form of protection, but it has proved hard to improve the robustness of digital watermarks and to find ways of preventing copy-based attacks. This paper proposes a new image authentication method that combines digital signatures and digital watermarking in the form of QR codes. Moving away from existing techniques, the proposed method uses image segmentation to exploit the error-correction capability of QR codes by converting the digital signature of each sub-block into a QR code before embedding it into the image. The digital signature is then saved as a watermark, which offsets the disadvantages of signature storage and is difficult to copy. Experiments show that the method is effective in terms of image noise and that the watermarks are robust and secure against copy-based attacks." @default.
