Vehicle Passenger Authentication System for Kidnapping Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle theft prevention systems are inadequate for detecting and notifying crimes like kidnapping, as they primarily rely on driver authentication and do not account for fellow passengers, and the management of identification information poses security risks.
Innovation Solution
A crime prevention system that authenticates vehicle passengers using a portable terminal, transmitting and receiving identification information between the vehicle and the terminal, with a controller that warns of inconsistencies and notifies pre-registered contact addresses in case of authentication failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver authentication is implemented using portable terminal identification information, then vehicle theft prevention is improved, but kidnapping detection capability deteriorates because fellow passengers cannot be authenticated
Solution Approach 1:
The authentication system is extended from driver-only to all vehicle occupants. The vehicle control device now performs authentication for any person entering the vehicle using their portable terminal, making the system universally applicable to all users regardless of their role (driver or passenger), thereby enabling both theft prevention and kidnapping detection.
Solution Approach 2:
Authentication is performed in advance when a person enters the vehicle, before any crime can occur. The vehicle control device collates identification information upon door opening or vehicle start, proactively verifying the occupant's identity before the vehicle is fully operational, which prevents both theft and kidnapping scenarios.
2Ease of operation
If identification information management is performed on the vehicle side, then authentication control is improved, but security level deteriorates due to risk of malicious registration
Solution Approach 1:
The portable terminal acts as an intermediary device that stores and manages identification information securely. Instead of the vehicle directly managing authentication data, the system uses the portable terminal as a trusted mediator that the user carries, eliminating the security vulnerability of vehicle-side storage while maintaining authentication control.
3Reliability
If engine start authentication is implemented, then vehicle unauthorized use prevention is improved, but post-start theft detection capability deteriorates
Solution Approach 1:
Authentication is not limited to the engine start moment but continues whenever the vehicle door is opened or closed. The vehicle control device repeatedly performs authentication checks during vehicle operation, maintaining continuous security monitoring that detects both pre-start and post-start unauthorized use including kidnapping scenarios.
Data Source
AI summary
A vehicle is provided with an identification information memory in which identification information of the vehicle is memorized, and a transmitter for transmitting the identification information. A portable terminal is provided with a receiver for receiving the identification information transmitted from the transmitter, a registration information memory in which identification information of a ridable vehicle is memorized as registration information in advance, and a controller for executing authentication between the identification information and the registration information and executing a warning processing when a result of authentication shows inconsistency.
