Title:
USER AUTHENTICATION METHOD, USER AUTHENTICATION DIGITAL KEY SYSTEM, AND MOBILE DEVICE PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/029285
Kind Code:
A1
Abstract:
A mobile device (2) establishes an NFC link with a card key (1) by the card key (1) being laid on the back surface part thereof. Further, the mobile device (2) is configured to be capable of performing BLE communication with a vehicle (Hv). The mobile device (2) plays the role of transferring a challenge code transmitted from the vehicle (Hv) by a BLE link to the card key (1) by NFC. The card key (1), when having received the challenge code from the mobile device (2), generates a response code from the challenge code using a vehicle key code saved in the card, and returns the response code to the mobile device (2). The mobile device (2) transfers the response code received by NFC to the vehicle (Hv) by BLE, thereby authenticating the user.
