Solution Overview

Problem

Existing vehicle authentication technologies lack robustness and convenience in integrating biological information for secure electronic payments, particularly in scenarios where multiple authorizations and payment types are involved.

Innovation Solution

A vehicle system incorporating a communication interface, sensors for biological information detection, and a controller that performs two-stage authentication using authentication information from a terminal apparatus and biological data, enabling secure electronic payments by acquiring authorization information for users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two-stage authentication using biological information is implemented, then security for electronic payments is improved, but device complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication process is divided into two distinct stages: first authentication using authentication information from the terminal apparatus, and second authentication using biological information from sensors. This segmentation allows each stage to handle specific security requirements independently, improving overall security while maintaining manageable system complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vehicle's controller acts as an intermediary that receives authentication information from the terminal apparatus via communication interface and also acquires biological information from sensors. This intermediary role enables the integration of multiple authentication sources without requiring direct complex interaction between the terminal apparatus and sensors, simplifying the system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multiple authentication methods are integrated, then authentication robustness is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveauthentication robustnessVSAvoidauthentication convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system merges multiple authentication methods (authentication information from terminal apparatus and biological information from sensors) into a unified two-stage authentication process. This combination provides robust security verification while the automated sequential execution maintains user convenience by reducing manual intervention requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The first authentication using authentication information from the terminal apparatus is performed preliminarily before the second authentication using biological information. This preliminary action filters out unauthorized users early in the process, making the overall system more robust while maintaining ease of operation by establishing a clear, predictable authentication flow.

Inventive Principle:

AI summary

A vehicle includes a communication interface, a sensor configured to detect biological information for a user of the vehicle, and a controller configured to perform electronic payments. The controller receives authentication information from a first terminal apparatus using the communication interface and acquires the biological information from the sensor when a first authentication using the received authentication information succeeds. The controller acquires authorization information indicating authorization to perform an electronic payment for the user, who is associated with the authentication information, when a second authentication using the acquired biological information succeeds.
