Biometric Access Control via Segmented Authentication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic personal and vehicle identification/authentication systems lack flexibility and efficiency, particularly in determining the identity of vehicle occupants for access control, relying on manual methods that are ineffective and inefficient.
Innovation Solution
A method and system that separates personal identity authentication into two communicating devices: a biometric authentication device for user identification and a wirelessly communicating device for transmitting access authorization requests to an electronic access controller, using ZigBee technology for secure communication, allowing for flexible and efficient access control based on biometric data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used for identifying vehicle occupants, then system complexity is reduced, but productivity and reliability deteriorate due to fraud and inefficiency
Solution Approach 1:
The system divides the access control function into two separate devices: a personal identity authentication device for biometric verification and a wirelessly communicating device for authorization requests. This segmentation enables automatic occupant identification while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The personal identity authentication device acts as an intermediary between the vehicle occupant and the access control system. It captures biometric data, authenticates the occupant's identity, and communicates authorization requests wirelessly, thereby automating the process and improving productivity without requiring direct manual intervention at each stage.
2Reliability
If biometric authentication devices are integrated into vehicles, then reliability of access control improves, but device complexity and manufacturing cost increase
Solution Approach 1:
Rather than integrating biometric authentication directly into the vehicle manufacturing process, the system uses separate, standalone personal identity authentication devices that can be independently produced and then deployed in vehicles. This segmentation maintains manufacturing simplicity while achieving reliable biometric-based access control.
Solution Approach 2:
The personal identity authentication device is designed as a universal solution that can be applied across different vehicle types and access control scenarios. Its multi-functionality allows it to serve various purposes (occupant identification, authorization requests, fraud prevention) without requiring custom manufacturing for each application, thereby improving reliability without proportionally increasing manufacturing complexity.
3Productivity
If electronic plates are used for vehicle identification, then productivity of traffic control improves, but adaptability deteriorates as they cannot identify current occupants
Solution Approach 1:
The system merges vehicle identification (via wirelessly communicating devices) with personal identity authentication (via biometric devices) into a unified access control solution. This combination maintains the productivity benefits of electronic identification while adding the adaptability to identify and authorize current occupants based on their biometric data, overcoming the limitations of electronic plates alone.

AI summary
A control system for access to a limited access area requires identification and preferably authentication of the accessing person; in order to achieve efficiency and effectiveness, the system need to be automatic. According to the present invention, the arrangement associated with the accessing person is split into at least two devices in communication between each other: a personal identity biometric authentication device (D1) and a wirelessly communicating device (D2); the authentication device (D1) is responsible for user authentication, while the communication device (D2) is responsible for transmitting requests of access authorization to an electronic access controller (D3).
