Abstract:
To determine a relation discrimination possibility of a pseudonymous-name communication identifier so that, in each communication layer, no mismatch occurs between a pseudonymous-name communication identifier whose relation can be discriminated and a pseudonymous-name communication identifier whose relation cannot be discriminated. The Relation discrimination possibility determination means 2 determines a relation discrimination possibility of a pseudonymous-name communication identifier of a specific communication layer among a plurality of communication layers to a designated one of relation discrimination possible and relation discrimination impossible. It determines a relation discrimination possibility of a pseudonymous-name communication identifier of other communication layers to relation discrimination possible or relation discrimination impossible according to which one of relation discrimination possible and relation discrimination impossible the pseudonymous-name communication identifier of the specific communication layer is.
