A Survey of Digital Vector Map Watermarking
نویسندگان
چکیده
The application of digital vector maps faces some unsolved issues such as digital copyright protecting, data authenticating, and data source tracing, etc. These issues could be obstacles restricting the further usage of digital vector maps. The technique of watermarking provides potential solutions for the problem. Comparing with the watermarking schemes designed for general multimedia data, watermarking a 2D vector map has some distinct features due to the special data structures and application environments of vector maps. These distinct features will be summarized in this paper by analyzing the characters of vector map data. Furthermore, an overview of the existing typical algorithms will be presented to show the state of the art of the study.

متن کاملRobust Vector Digital Watermarking Using Angles and a Random Table
In this paper I propose a new digital watermarking method using angles. Angles like distance are not changed easily in vector data. Because of this, the proposed method is robust to scaling. In previous methods there are distortion and topology change. However, this proposed method doesn’t have distortion and topology change because I used intersection test. Therefore, the proposed method could...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملRobust watermarking of vector digital maps
Digital maps are used, for example, in car navigation systems and web-based map services. As digital data, digital maps are easy to update, duplicate, and distribute. At the same time, illegal duplication and distribution or forgery of the maps is also easy. This paper proposes a digital watermarking algorithm for vector digital maps as a method to counter such abuses of the maps. A watermark b...
