Abstract

Message spoofing is detected by an anti-spoofing application comparing a trusted switch address (i.e., corresponding to an originating switch having processed an incoming message) to an “affiliated” address (i.e., corresponding to a switch serving the location of the identified sender). Message spoofing is detected if the trusted address differs from the affiliated address.
