The main concept of City.Risks is to place information sharing at the center of addressing security challenges in large urban environments:
- what – diverse types and sources of information need to be analysed, integrated and exploited, including historical crime data and statistics, victimization reports, demographic data, maps of transportation networks and other city infrastructures, available physical sensors, news feeds and the Web.
- whom – citizens are in the centre of the approach, actively being engaged as both targets and sources of information, in a bidirectional communication channel between either citizens and the authorities or among citizens themselves within trusted networks or broader communities.
- when – the ultimate goal is to ensure timely sharing of appropriate information both for preventing security threats as well as mitigating their impact when they actually occur.
- how – by primarily utilising citizens' smart phones and mobile devices for appropriately visualising the needed information as well as feeding information back to the platform.
