Abstract
While Digital Watermarking has received much attention within the academic community and private sector in
recent years, it is still a relatively young technology. As such, there are few accepted tools and metrics that
can be used to validate the performance claims asserted by members of the research community and evaluate
the suitability of a watermarking technique for specific applications. This lack of a universally adopted set of
metrics and methods has motivated us to develop a web-based digital watermark evaluation system known as the
Watermark Evaluation Testbed or WET. This system has undergone several improvements since its inception.
The ultimate goal of this work has been to develop a platform, where any watermarking researcher can test not
only the performance of known techniques, but also their own techniques. This goal has been reached by the
latest version of the system. New tools and concepts have been designed to achieve the desired objectives. This
paper describes the new features of WET. Moreover, we also summarize the development process of the entire
project as well as introduce new directions for future work.
