Development of Benchmark Tool for Digital Watermarking

Digital watermarks are used to prevent unauthorized use of digital content, such as illegal copying and falsification. Benchmark tools for digital watermarks are necessary to measure the strength of a digital watermark. For example, Stirmark and JEWELS are well known benchmark tools. However, the functions of existing tools are not enough, because they do not have evaluation functions using plural images. In addition, they are difficult to use, because they command line-based software without an image viewer. Therefore, this paper shows a new benchmark tool that supports evaluations using plural images and has a graphical user interface.
