A method of anonymising an interaction between a user entity comprising a computing device and a service provider node wishing to provide a service via a network to the user entity in dependence upon characteristics of the user entity determined or revealed as a result of the interaction, said interaction having a value associated therewith, the method comprising:

  • assigning the user entity to at least one set, each set comprising as members a plurality of user entities sharing a characteristic associated with that set;

    counting the number of user entities in a said set or in an intersection of the at least one set and calculating a share of said value attributable to each user by dividing the value by the number of user entities in the set;

    ensuring that said set or the intersection of the at least one set comprises at least a predetermined minimum number of user entities; and

    providing to the service provider node, as part of the interaction, information relating to the or each characteristic associated with each set, the information being for use at the service provider node in providing the service to the user entity, as part of the interaction, that is appropriate in view of the characteristics of the user entity but insufficient to identify the user entity;

    wherein the assigning, ensuring and providing steps are performed at an anonymiser system disposed on a communication path between the user entity and the service provider node, the anonymiser system comprising a cooperation of nodes, wherein anonymised service is provided to the user entity via the anonymiser system as part of the interaction between the user entity and the service provider.
