Abstract: An entity communicates with a central authority to issue an asset to an individual. The asset has associated therewith a distinct URI or “unique ID”. The asset uniquely identifies the individual to the issuing entity and to other entities in communication with the central authority. Select data about the individual obtained by one or more entities is stored in the central authority or in a network memory in communication therewith using the Resource Description Framework, which allows for this data to be queried by the entities with increased efficiency.

Abstract: A method for mapping and handling interactions between entities in a network comprises calculating an initial trust value between pairs of the entities based on previous interactions between those entities, where the trust value indicates the degree of trust associated with the interaction, and determining, for each entity, one or more pair-wise relationships between a selected entity and any of the other entities with which the selected entity has interacted. The method also comprises generating a graphical representation of all of the entities based on the relationships determined for each pair of entities, and the calculated trust value associated with the interaction between each pair of entities; iteratively propagating the initial trust values to all entities in the graphical representation so as to calculate a current trust value associated with each entity; and analysing the calculated current trust values to determine an appropriate action to be taken.
