Abstract
A fraud detection method includes: determining whether a period of a message repeatedly transmitted in an in-vehicle network is anomalous; detecting whether arbitration occurs when the message is transmitted in the in-vehicle network; and determining that the message is an anomalous message, in the case where the period of the message is anomalous and no arbitration occurs when the message is transmitted in the in-vehicle network.
