Title:
COMMUNICATION DEVICE, COMMUNICATION METHOD AND COMMUNICATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/104122
Kind Code:
A1
Abstract:
In the present invention, a communication unit sends and receives messages on a network. A first fraud detection unit detects a fraudulent message by detecting a plurality of monitoring item values from a message received by the communication unit and determining whether each of the plurality of monitoring item detected values falls within a corresponding reference range. For each of the plurality of monitoring items, a first reference range and a second reference range, which is narrower than the first reference range, are set. The first fraud detection unit determines the message to be a fraudulent message when one of the detected values is outside the first reference range, and determines the message to be a fraudulent message if a prescribed rule is satisfied when one of the detected values is within the first reference range and outside the second reference range.
