DEVICE FOR VERIFYING IDENTITY BETWEEN OPERATING RULES OF SENSOR DEVICES

WIPO Patent Application WO/2018/167967

A1

In response to a request from an analysis device 13, a first server device 12 transmits detection result data received from sensor devices 11-1 to 11-n. Terminal devices 15-1 to 15-n are connected to the sensor devices 11-1 to 11-n, respectively. The terminal devices 15-1 to 15-n transmit, to a third server device 16 at predetermined time intervals, message digests representing rule data relating to programs, parameters, etc. that are stored in the sensor devices 11-1 to 11-n connected to the terminal devices 15-1 to 15-n respectively. The third server device 16 determines the consistency of detection result data generated by each of the sensor devices 11-1 to 11-n on the basis of the message digests received from the terminal devices 15-1 to 15-n. When using detection result data received from the first server device 12, the analysis device 13 receives, from the third server device 16, determination result data indicating consistency determination results of those detection result data, and performs analysis using consistent detection result data.
