Digital Watermarking Algorithm for 2D Vector Graphics

Published: 25 May 2020 Publication History

Abstract

At present, digital watermark technology has been relatively mature in the security protection of images, video, audio and other fields, and has achieved many successful applications. In contrast, there are relatively few watermarking methods for vector graphics copyright protection. We propose a digital watermarking algorithm for the vector graphics drawn by the spline. Firstly, we grab the color values of vector graphics and construct a color matrix. Then DWT decomposition and Slant transformation are performed on the color matrix. Finally, the watermark image is embedded in the low frequency component of the color matrix. Experimental results show that not only the watermark information is successfully hidden to the vector graphics, but also the algorithm can effectively resist object modification attacks.
