Vehicle Messaging Validation via Central Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for vehicles lack efficient methods to facilitate secure and reliable messaging between vehicles and external devices based on location validation, leading to challenges in message delivery and authentication.
Innovation Solution
A messaging system comprising a central computer, portable computer, and vehicle computer that uses image tags or wireless identifiers to validate locations and authenticate messages, ensuring secure transmission between devices within a threshold distance by matching location coordinates and alphanumeric codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location validation and authentication mechanisms are implemented for vehicle messaging, then message security and reliability are improved, but system complexity increases
Solution Approach 1:
A central server acts as an intermediary between portable devices and destination devices. The server receives validation data from portable devices, determines corresponding destination devices, and routes messages appropriately. This intermediary approach centralizes the complexity of location validation and authentication logic, making the system more manageable while ensuring reliable message delivery.
Solution Approach 2:
The system performs preliminary location validation and authentication before message transmission. Portable devices must provide validation data (such as location information) that the central server verifies against stored data. Only after successful validation is the message transmitted to the destination device. This preliminary action ensures message reliability while organizing complexity into distinct validation and transmission phases.
2Reliability
If location coordinates and validation data are verified before message transmission, then message authentication is improved, but communication time increases
Solution Approach 1:
Location validation data is collected and prepared in advance before message transmission is initiated. The portable device gathers validation information (such as current location coordinates) and submits it to the central server as part of the message routing process. The server performs deterministic matching of validation data to destination devices, allowing authentication to occur efficiently without significant time delay.
Solution Approach 2:
Portable devices automatically provide their own validation data (such as location information from their sensors) without requiring manual input or additional verification steps. The central server uses this self-provided data to determine the destination device. This self-service approach streamlines the authentication process, reducing the time required for validation while maintaining security.

AI summary
A central computer includes a first processor and a first memory. A portable computer includes a second processor and a second memory. The portable computer is programmed to: obtain an identifier of a vehicle via a scanner included in the portable computer, and transmit the identifier and first validation data to the central computer, and transmit a message to the central computer for a destination computer. The central computer is programmed to receive the identifier and the first validation data from the portable computer, determine second validation data; identify a destination computer based on the identifier, and upon determining that a comparison of the first validation data and the second validation data meets a specified criterion, transmit the message from the portable computer to the destination computer.
