ABSTRACT
This article presents a blind watermarking method for vector graphics images. Unlike the common watermarking methods, where the image luminance is altered, the coordinates of the polygonal curve vertices are modified in the presented method. The watermark is embedded in the Fourier descriptors of the vertices of the polygonal lines, resulting in slight alterations of the polygonal line?s vertex coordinates. Due to the Fourier descriptor properties, the watermark is detectable even after rotation, translation, scaling, additive Gaussian noise, smoothing, reflection attacks, or combination of these attacks.
