With the We Are ecosystem, VITO is helping to develop a radically new and different way of dealing with personal (health) data of citizens. This is done by means of an innovative technological component but also by the development of new applications, such as the online prevention platform BIBOPP. It is intended to give citizens confidence in how their privacy-sensitive data are used - and above all: by whom and why - and thus to ‘empower’ them in terms of their data and personal health.
