The purpose of this Decision is to ensure an effective development of this network – known as ICONET – and in particular the rapid exchange of relevant information required by the Member States’ Migration Management Services in their fight against illegal immigration. The network enables Member States to transmit confidentially early warning messages relating to illegal immigration. The network can also be a useful tool for enhancing co-operation among immigration liaison officers posted abroad by the Member States. It is not envisaged – for technical and legal reasons – to exchange personal data via the Network.
