Method for Vector Map Protection based on using of a Watermark Image as a Secondary Carrier

Yuliya Vybornova, Vladislav Sergeev

Abstract

In this paper, we present a study of the watermarking method for vector cartographic data based on a cyclic shift of a polygon vertex list. We propose a method modification to provide an accurate authentication procedure, as well as to increase the method robustness against map contents modification. The main idea of the improved method is to use a noise-like image as a secondary carrier for a watermark, represented in the form of a bit vector. An algorithm for construction of a noise-like image carrying a watermark sequence, as well as an algorithm for extraction of such a sequence, are given. An experimental study explores the information capacity of the carrier image and its robustness against quantization and noise adding, i.e. distortions simulating the embedding into map objects. The efficiency of the method is also demonstrated on real cartographic data. Conclusions comprise optimal parameters for reliable extraction depending on the number of polygons on the vector map.
