Vehicular Assistance Device Facility ID Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking area systems are vulnerable to information leakage to unauthorized third parties due to the transmission of user IDs to invalid access points, which can abuse user-specific information.
Innovation Solution
A vehicular assistance device equipped with a facility ID reception, area information acquisition, position information acquisition, and determination components that validate the facility ID based on vehicle position and area information before transmitting a user ID for assistance information, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the in-vehicle device transmits user ID to any received access point, then assistance information can be received from valid facilities, but user information may leak to unauthorized third parties
Solution Approach 1:
The system performs preliminary validation by comparing the received facility ID with pre-stored area information and vehicle position data before transmitting the user ID. This preliminary check ensures that only access points located within the authorized facility area can receive user information, preventing information leakage to unauthorized third parties while maintaining reliable assistance information reception.
Solution Approach 2:
The patent introduces an intermediary validation mechanism that acts as a mediator between the user ID transmission and the facility access point. The system uses stored area information and position data as intermediary checks to verify whether the received facility ID corresponds to a legitimate location, thereby controlling information flow and preventing unauthorized access.
2Object-affected harmful factors
If the system validates facility ID using position information and area information, then information leakage is prevented, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by using the same position information and area information storage that already exists for assistance information reception purposes. This existing data structure serves dual functions: both for receiving assistance information and for validating facility IDs, thereby preventing information leakage without requiring separate dedicated validation hardware or data structures.
Solution Approach 2:
The validation mechanism utilizes the vehicle's own position information and the pre-stored area information of facilities to perform self-validation. The system serves itself by comparing received facility IDs against its own stored data, eliminating the need for external validation servers or complex third-party verification systems.

AI summary
A vehicular assistance device, which is equipped to a vehicle and performs a wireless communication with a facility-side device to receive assistance information useful to a user from the facility-side device, includes a facility ID reception portion receiving a facility ID used for identifying a facility from the facility-side device, an area information acquisition portion acquiring area information related to a position of the facility, a position information acquisition portion acquiring position information of the vehicle, a determination portion determining whether the received facility ID is valid based on the position information of the vehicle and the area information related to the facility corresponding to the received facility ID, and a user ID transmission portion, when the facility ID is valid, transmitting, to the facility-side device, a user ID used for identifying the user as a request for transmitting the assistance information.
