Abstract
A node (17, 21) in an information centric network (ICN) receives a first identifier associated with an information object. The node (17, 21) causes creation of a virtual node (18) in the ICN, for holding a mapping between a second identifier and the first identifier. The second identifier is assigned to a copy of the information object stored in the ICN. The node (17, 21) causes creation of the virtual node (18) such that the mapping is arranged to cease after a predetermined event. The virtual node (18) is created with the sole purpose of providing copies of the information object to a small number of requestors (14), and possibly to just one requestor (14). Ceasing the mapping after delivery of the one copy, or the few copies, of the information object prevents unauthorized retrieval of the information object.
