Abstract

A destination inconsistency judgment apparatus, a destination inconsistency judgment method, and a medium recorded with a destination inconsistency judgment program are provided, in which a destination-information designating an information-exchange-destination is compared with a transmitter-information included in a transmitted exchangee-information, and it is judged that an inconsistency has occurred in the destination-information when the destination-information and transmitter-information are inconsistent with each other. Further, a destination inconsistency correction apparatus, a destination inconsistency correction method, and a medium recorded with a destination inconsistency correction program are provided, in which the transmitter-information is added, as the destination-information, when it is judged that an inconsistency has occurred in the destination-information.
