Abstract
A method for watermarking of polygonal lines is proposed. The watermark is embedded in the Fourier descriptors of the polygonal line causing minor distortions to the coordinates of the vertices of the polygonal line. Watermarks generated by this technique can be successfully detected even after rotation, translation, scaling and reflection of the host polygonal line
