The Responsibility to Share principle entails the voluntary sharing of information, even when not specifically requested by another party, but on the basis that it is deemed useful. Through its implementation the overall performance of all authorities responsible for maritime surveillance should improve. By increasing information sharing, a more complete overall maritime picture can be drawn up, leading to more effective preventive and protective measures being implemented and will help to create a sense of joint responsibility.
One of the activities of the transitional phase of CISE is to define an audit scheme to assess the exchange of information. This audit scheme will support those participating in the CISE network to implement the responsibility to share principle.
