Vehicle Access Authorization via Encrypted Mobile Data Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive authorization systems for vehicles require personal access passwords for authentication, which are not suitable for allocating storage areas to companies, and lack efficient methods for secure, economic, and scalable access authorization management, especially in rental or shared vehicle scenarios.
Innovation Solution
A device and method utilizing a mobile communication device with a data carrier having protected storage areas, where authorization data is encrypted and transmitted from a database server, enabling secure, scalable, and efficient allocation of access and driving authorizations without relying on the mobile device's operating system, allowing for near-field communication and wireless energy transmission, and facilitating easy blocking of authorizations if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal access passwords are used for authentication in existing drive authorization systems, then user authentication is enabled, but the system cannot allocate storage areas to companies and lacks scalability for rental or shared vehicle scenarios
Solution Approach 1:
The patent segments the authorization system by introducing separate authorization data structures that are independent of personal access passwords. The authorization data is divided into company-specific segments that can be allocated to different entities, enabling flexible assignment while maintaining system security through structured data organization.
Solution Approach 2:
The patent introduces an intermediary authorization management layer that sits between the personal authentication system and the vehicle access control. This intermediary layer handles the allocation and management of authorization data, enabling company-specific storage area allocation without requiring changes to the underlying authentication infrastructure.
2Ease of operation
If authorization data is stored on mobile communication devices, then access availability is improved, but security risks increase from infected devices or battery failure
Solution Approach 1:
The patent implements beforehand cushioning by designing the authorization system to be independent of the mobile device's operational state. The authorization data is structured to be verifiable without requiring the device's operating system, battery, or software to be functional, thus cushioning against security risks from infected or battery-less devices.
Solution Approach 2:
The patent replaces reliance on the mobile device's mechanical and software systems (battery, operating system, processors) with a cryptographic verification system. The authorization data contains embedded verification mechanisms that can be validated through mathematical proofs rather than requiring the device's hardware or software to be operational.
3Ease of operation
If traditional key systems are used for vehicle access, then security is maintained, but convenience and remote authorization management are limited
Solution Approach 1:
The patent makes the mobile communication device universal by enabling it to serve both as a standard communication device and as a vehicle authorization key. The same device can store and present authorization data for multiple vehicles and multiple companies, eliminating the need for separate physical keys while maintaining security through cryptographic verification.
Solution Approach 2:
The patent uses copying by creating digital replicas of authorization credentials that can be distributed remotely. Instead of physical keys, the system creates and distributes digital authorization data that can be copied to mobile devices, enabling remote provisioning and management of vehicle access rights without physical contact or complex infrastructure.
