The social importance of the Information and Communication Technologies in general and the Internet in particular, has been translated into a more and more easy way of carrying out whatever kind of commercial transactions by means of the network. In this sense, the electronic-bank services (e-bank) constitute an important risk in terms of fraud to users or entities.
In this context, the collaboration with Universidad Politécnica de Cataluña in this research contract implies the modeling of the normal behavior of legitimate users in order to discover and detect abnormal situations and behaviors in e-bank services, and to react against them.
