Illustration Watermarks for Vector Graphics
Digital watermarking is a technique for embedding information into data, such as images, 3D models, or audio files, such that some properties (i. e., security, imperceptibility, robustness) are maintained. While most of the existing watermarking techniques focus on encoding copyright information where security is one of the most important properties, we have developed algorithms for embedding Illustration Watermarks, i. e., content-related annotations for the image. Robustness against common media transformations, high capacity, and blind detection are our aspired properties while security and the usage of secure keys are less important. The medium that we are using for embedding data are 2D vector graphics. We introduce algorithms that change line attributes, introduce new vertices in certain patterns, and replace existing stroke segments by new lines in a stylistic way. Based on the modification they introduce, we categorize our techniques into whether they change the appearance o...
