Vehicle Authentication via Physical Operation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems lack effective authentication methods to confirm that a user of an electronic device is an authorized user of a vehicle, making it vulnerable to malicious access and unauthorized actions.
Innovation Solution
A system and method that involves a processor in the vehicle communication system verifying user authorization by requiring the user to perform specific operations, utilizing cryptographic credentials to generate digital signatures, and authenticating these signatures through a remote device to ensure access and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication mechanisms are added to verify user identity, then security against malicious access is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary authentication actions by requiring the user to cause the vehicle to perform specific operations (such as flashing lights or honking horn) before granting access to remote device communication. This preliminary verification ensures that the person initiating the request has physical access to and control of the vehicle, thereby establishing user identity before the actual communication transaction occurs.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that mediates between the user's request and the remote device communication. Instead of directly allowing communication, the system uses an intermediate verification step where the vehicle itself acts as a mediator to confirm user identity through predefined operations, adding a security layer without requiring complex biometric or cryptographic systems.
2Ease of operation
If simple authentication methods are used, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system enables the vehicle to perform self-verification by executing predefined operations (such as lighting indicators or emitting sounds) that automatically confirm user identity. The vehicle itself serves as the authentication mechanism, eliminating the need for external verification systems or complex user interactions, thereby maintaining ease of operation while improving security.
3Reliability
If vehicle operations are required for authentication, then confirmation of user control is improved, but time to complete requests increases
Solution Approach 1:
The authentication process uses periodic, predetermined vehicle operations (such as flashing lights for a specific duration or honking at set intervals) that can be quickly executed and verified. These periodic actions are designed to be brief and standardized, allowing the system to confirm user control rapidly without requiring extended verification procedures, thus minimizing the time added to the request process.

AI summary
Methods and a system are provided for confirming that a user of an electronic device is an authorized user of a vehicle. The method comprises receiving a request regarding the vehicle from the electronic device in response to a user action, verifying that the user is able to cause the vehicle to perform a predetermined operation, and permitting the request to proceed only if the vehicle performs the predetermined operation.
