Electronic Motor Vehicle Display Apparatus for Secure License Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle display systems lack efficient and secure methods for updating vehicle license numbers, requiring physical replacement of license plates and involving resource-intensive administrative processes.
Innovation Solution
A motor vehicle display apparatus with an integrated electronic device that securely receives and authenticates data and certificates via wireless interfaces, allowing for cryptographic updates of the license number without physical plate replacement, using a public key infrastructure and bi-stable displays for efficient and secure data display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical license plates are used and updated through administrative processes, then secure identification is achieved, but resource consumption increases and updating becomes inefficient
Solution Approach 1:
The patent replaces physical license plates with electronic displays that show license number information. The display apparatus creates a visual copy of the license plate information without requiring physical plate manufacturing, distribution, and disposal. This eliminates resource consumption associated with physical plates while maintaining the identification function.
Solution Approach 2:
The patent substitutes the mechanical/administrative system of physical plate replacement with an electronic data transmission and display system. License numbers are updated wirelessly through cryptographic authentication, eliminating the need for physical plate issuance, installation, and disposal processes.
2Reliability
If cryptographic authentication is implemented for secure data transmission, then security is improved, but device complexity increases
Solution Approach 1:
The display apparatus integrates multiple functions into a single device: it displays license number information, performs cryptographic authentication, and handles wireless data transmission. By combining these functions in one apparatus rather than separate systems, the patent reduces overall system complexity while maintaining security.
Solution Approach 2:
The authentication system is designed to operate automatically between the display apparatus and the external device without requiring manual intervention. The cryptographic protocols execute self-service authentication, reducing operational complexity despite the underlying security mechanisms.
