In this book you can read about a research. This research is about whether it is possible to develop a mouse dynamics-based system. In this book you can read about data collection and how the data was collected. The processing and cleaning of this data. Then you can read about the different artificial intelligence methods used to build the models. After that, the performance analysis can be read. Finally, the application development process is illustrated. The development and research was done when I was still a B.Sc. It was through this work that I started my journey towards artificial intelligence research. Also, I was very interested in solving some interesting problem using such methods. Hence the choice of mouse dynamics, as it is an important thing that no one can use our machine and if we detect intrusion we can protect our data.
