Title:
EXTRACTION DEVICE, EXTRACTION METHOD, RECORDING MEDIUM, AND DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/207764
Kind Code:
A1
Abstract:
Provided are an extraction device, etc., with which it is possible to detect fraud on a frame that comes off a cycle. The extraction device is provided with: a frame selection unit for selecting between a frame that maintains a cycle and a frame that comes off a cycle for each frame of the same identifier, which are frames for which the identifiers associated with a node are the same; and a rule extraction unit for extracting, from a frame that comes off a cycle and has the same identifier, the feature of bit change of a data field related to event occurrence in the frame.
