Information and communication technologies (ICT) have become part of our everyday life and it is almost impossible to imagine life without them. Reason for that is the increasing digitalization of our world. Especially in our economic sector ICTs are one of the most driving factors for innovation and therefore strongly responsible forthe competitiveness of many companies. But ICTs not only influence our lives within economy, they also shape our society e.g. in authorities.
