Vehicle Door Opening Authentication Using Location Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless and contactless services, such as vehicle door opening and payment services, are vulnerable to relay attacks, leading to security concerns due to the lack of authentication and location verification.
Innovation Solution
A service processing method that involves sending identifiers between devices to determine the authenticity of the location, prompting user authentication if the location is abnormal, and verifying location information through secure modules to ensure legitimate service execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless and contactless services are performed automatically without user intervention, then user convenience is improved, but security is worsened due to vulnerability to relay attacks
Solution Approach 1:
The system performs preliminary location verification and authentication checks before executing the service. The first device verifies the location of the second device through multiple mechanisms (GPS location matching, historical location comparison, abnormal location detection) prior to allowing the service to proceed, preventing relay attacks before they can succeed
Solution Approach 2:
The patent introduces an intermediary verification mechanism where the first device acts as a mediator between the service request and execution. It receives service requests, performs location-based authentication, and only permits service execution after verification, thereby mediating between convenience and security requirements
2Reliability
If location verification and authentication mechanisms are implemented, then security is improved, but system complexity is worsened
Solution Approach 1:
The authentication system is segmented into multiple independent verification modules: GPS location acquisition module, historical location storage module, location comparison module, and service execution control module. Each module performs a specific function, making the overall system more manageable and maintainable despite its comprehensive security checks
Solution Approach 2:
The system performs self-verification by comparing current location data with historical location data stored in the first device. The device automatically detects abnormal locations and controls service execution based on its own verification results, reducing the need for external authentication servers and simplifying the overall architecture

AI summary
A service processing method includes receiving, by a mobile phone, a first identifier from a head device of a vehicle after the head device receives a trigger request to perform a vehicle door opening service, determining, by the mobile phone based on the first identifier, to perform authentication, indicating, by the mobile phone, the head device to perform the vehicle door opening service when the authentication succeeds, or determining, by the mobile phone based on the first identifier, not to perform the authentication, and sending, by the mobile phone, location information of the mobile phone, and an indication that indicating a location of the mobile phone and a location of the head device are normal to the head device.
