A watermarking system for teaching intellectual property rights: Implementation and performance

In this paper we propose a watermarking system, which we call WaterIP, that can be efficiently used in support of teaching students to respect intellectual property rights. Our system uses an efficient technique for watermarking images by exploiting certain properties of a specific 2D representation of permutations, it has a friendly graphical user interface, and shows interesting performance figures. We demonstrate the educational effectiveness of our WaterIP system by presenting ways of how it can be applied in class and show that WaterIP helps to understand what intellectual property rights really stand for. We have implemented our system and evaluated it in an simulated environment; the experimental results show that WaterIP has optimal time and space performance. Apart from that the figures show that the system provides watermarked images of high quality and everything is accessed through a user interface leading to the desired educational efficiency.
