Active databases have been used in many different fields to accomplish many different tasks. One
of the main problems today that still have not been solved is authorization. In some situations it is
enough that user knows e.g. password, in other situations it is enough that user posses e.g. a
smart card, but, there are also situations where user’s unique physical or psychological
characteristics need to be measured. In this paper we are going to put accent on this third
possibility. We will show how the concept of complex events presented in the active database theory
could be used in order to build a  multimodal biometric system. Especially, we will explore the
paradigm of active rules and complex events, and apply them in order to implement a multimodal
biometric system.
