Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote vehicle unlocking mechanisms require manual authorization and may not fully eliminate administrative delays, especially for users arriving in groups after travel, and lack enhanced security measures.
Innovation Solution
A method utilizing a mobile terminal with data processing and biometric acquisition capabilities, connected to a server and vehicle locking equipment, which transmits authentication requests, acquires and verifies biometric data, and encrypts virtual keys for secure remote unlocking, eliminating the need for manual authorization and enhancing security through cryptographic functions and zero-knowledge proofs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual authorization and key handover procedures are used at the rental counter, then administrative formalities can be completed, but users experience long waiting times especially when arriving in groups
Solution Approach 1:
The system performs authorization and key distribution actions in advance. Users can pre-register their biometric data and receive digital keys before arriving at the rental location. When users arrive, the system automatically verifies their identity and makes keys available without requiring manual authorization, thus eliminating queueing time while maintaining security procedures
Solution Approach 2:
The system enables users to independently complete the key retrieval process through biometric authentication. The automatic recognition system compares biometric data with stored reference data and provides keys without human intervention, allowing users to serve themselves and eliminating the need for counter staff to manually process each user
2Ease of operation
If remote unlocking mechanisms with virtual keys are implemented, then physical key handover is eliminated, but manual authorization procedures remain and administrative formalities are not fully eliminated
Solution Approach 1:
The system replaces manual authorization procedures with automatic biometric recognition. Instead of requiring staff to verify identities and manually issue keys, the system uses automated comparison of biometric data with stored reference data to authenticate users and distribute digital keys, thereby maintaining convenience while reducing procedural complexity
Solution Approach 2:
The system introduces an automatic biometric recognition system as an intermediary between the user and the key distribution process. This intermediary automatically verifies user identity by comparing biometric data with reference data stored in the database, eliminating the need for manual authorization while maintaining security and simplifying the overall procedure
3Reliability
If traditional authentication methods are used, then administrative procedures can be completed, but security against unauthorized access is insufficient
Solution Approach 1:
The system changes the authentication parameter from manual verification of documents to automatic biometric verification. By using unique physiological characteristics (fingerprints, facial recognition, etc.) as the authentication parameter, the system significantly enhances security reliability while the automated process keeps the implementation complexity manageable
