Robotaxi User Authentication With Backup Keypad Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication systems for robotaxis fail when authentication errors occur or the user's smartphone dies, leading to unauthorized access or denial of service.
Innovation Solution
A system and method that utilizes a combination of a smartphone, authentication server, and robotaxi components, including a touch keypad and biometric sensors, to authenticate users through multiple verification methods, ensuring secure access even in the event of authentication errors or smartphone failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital key authentication is used via smartphone, then authentication convenience is improved, but authentication reliability deteriorates when smartphone fails or authentication errors occur
Solution Approach 1:
The patent implements a backup authentication mechanism using a touch keypad and authentication number that is prepared in advance on the robotaxi. When the primary smartphone-based digital key authentication fails or the smartphone is unavailable, the user can alternatively input the authentication number through the touch keypad to unlock the door, ensuring authentication reliability is maintained despite smartphone failures
Solution Approach 2:
The patent introduces an intermediary authentication number that serves as a bridge between the user and the robotaxi authentication system. This authentication number can be obtained through the smartphone application or alternative channels, and can be input via the touch keypad when the smartphone is unavailable, acting as a mediator that maintains authentication functionality across different failure scenarios
2Reliability
If multiple authentication methods are provided, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the authentication system into two distinct authentication paths: primary authentication via smartphone digital key and backup authentication via touch keypad with authentication number. Each segment operates independently, allowing the system to switch between them based on failure conditions without requiring complex integration logic, thus maintaining relatively simple system architecture while improving reliability

AI summary
An embodiment system for authenticating a user of a robotaxi includes an authentication server and a robotaxi. The authentication server configured to create a first authentication number, transmit the first authentication number to a smart phone the user, receive a second authentication number from the robotaxi when authenticating the user using a digital key fails, and request unlocking of a door to the robotaxi when the first authentication number and the second authentication number match. The robotaxi configured to receive the second authentication number from the user, transmit the second authentication number to the authentication server, and unlock the door in response to the request from the authentication server.
