Mobile Terminal Vehicle Authentication Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminal technologies require separate key devices for controlling vehicles, which can be inconvenient and may not provide adequate security features.
Innovation Solution
A mobile terminal with a vehicle authenticating unit that performs key authentication and dual authentication using short-range communication and NFC, allowing control of vehicles without a separate key device and enhancing security through multiple authentication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate key device is used for vehicle control, then vehicle security is maintained, but user convenience deteriorates due to carrying multiple devices
Solution Approach 1:
The patent combines the mobile terminal and vehicle key device into a single integrated device. The mobile terminal includes both a communication unit for mobile network communication and a short-range communication unit for vehicle authentication, eliminating the need to carry separate key devices while maintaining vehicle control functionality
Solution Approach 2:
The mobile terminal is designed to perform multiple functions: it serves as both a general communication device and a vehicle authentication device. The short-range communication unit can authenticate with multiple different vehicles, making the device universal for various vehicle access scenarios
2Reliability
If dual authentication is implemented, then vehicle security is enhanced, but authentication time increases
Solution Approach 1:
The patent performs preliminary authentication using the short-range communication unit before the user needs to access the vehicle. The mobile terminal authenticates with the vehicle in advance, storing authentication results so that when the user approaches the vehicle, access is granted quickly without requiring time-consuming dual authentication procedures
Solution Approach 2:
The mobile terminal acts as an intermediary that manages the dual authentication process. It coordinates between the short-range authentication and mobile network authentication, optimizing the sequence and timing of authentication steps to minimize user-perceived delay while maintaining security
