Vehicle Device Grouping via Server-Mediated Zone Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming groups of devices within a movable spatial region, such as vehicles, are insecure and complex, particularly when using NFC or Bluetooth, as they often require direct device contact and lack authorization verification, and are not suitable for forming larger groups or managing device connections efficiently.
Innovation Solution
A method and device for data transmission between mobile stations within a movable spatial region, which involves identifying and verifying the presence of mobile stations within a localized zone using position-finding techniques, and then interconnecting them for secure data transfer without the need for explicit user intervention, using an interconnection device that can be integrated into the vehicle or accessed via a remote server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC or Bluetooth are used for device interconnection, then direct device contact and data transfer are enabled, but security is compromised due to lack of authorization verification and device complexity increases for managing connections
Solution Approach 1:
The patent introduces a server as an intermediary that mediates device interconnections. The server receives connection requests, verifies authorization credentials, and manages the pairing process between devices. This resolves the security issue by providing centralized authorization verification while maintaining ease of operation through automated server-mediated connection establishment.
2Reliability
If manual authorization verification is implemented for device pairing, then security is improved, but ease of operation deteriorates due to requiring explicit user intervention
Solution Approach 1:
The patent implements preliminary action by having users register their devices and authorization credentials with the server in advance. The server stores these credentials and automatically verifies them during connection requests. This resolves the contradiction by performing security verification beforehand, allowing spontaneous connections without real-time user intervention while maintaining security through pre-configured authorization.
3Reliability
If position-finding techniques are used to verify device presence within localized zones, then unauthorized access is prevented, but device complexity and measurement difficulty increase
Solution Approach 1:
The patent uses the server as an intermediary to handle position verification. Mobile devices transmit their location data to the server, which then verifies whether devices are within authorized localized zones based on pre-configured geographic boundaries. This resolves the complexity issue by centralizing the computation-intensive position verification on the server rather than requiring complex onboard processing in each mobile device, while maintaining reliable access control through server-side geographic validation.

AI summary
The method simplifies the formation of groups of devices in secure spaces. Such spaces may be passenger compartments of vehicles, and the passenger compartments can additionally be partitioned into zones. Each zone can be allocated a group. For instance, driver and front-seat passenger can be allocated to one group. The travelers in the rear seat-rows can be allocated to another group. This allows data exchange with driver and front-seat passenger that relates to the vehicle route or even relates to vehicle assistance systems. The other group, for instance, children travelling in the vehicle, can share other data, for instance, for entertainment purposes. The acceptance of systems offered in the vehicle can be increased by simple group formation.
