Title:
DATA TRANSMISSION PATH CONFIRMATION SYSTEM, DATA TRANSMISSION PATH CONFIRMATION METHOD, DATA RELAY SYSTEM, AND DATA RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/162191
Kind Code:
A1
Abstract:
An authentication station (10) is configured to be capable of transmitting electronic certificates (C, CA, CB). A processing device (11) adds a signature (S) and an electronic certificate (C) to data (D) and transmits the same to a company-A system (1A). The company-A system (1A) adds a signature (SA) and an electronic certificate (CA) to the received data and transmits the same to a company-B system (1B). The company-B system (1B) adds a signature (SB) and an electronic certificate (CB) to the received data and transmits the same to a user terminal (12). The user terminal (12) verifies, between the authentication station (10) and itself, the electronic certificates (C, CA, CB) that are cumulatively added to the received data, and confirms the transmission path of the data (D) on the basis of the cumulatively added electronic signatures (S, SA, SB).
