Wireless Biometric Data Transfer for Cross-Device Enrollment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fingerprint matching techniques can become cumbersome during enrollment, especially when multiple fingerprints or devices are involved, requiring repetitive processes and potentially complex data management.
Innovation Solution
An electronic system with a first and second device, each equipped with biometric sensors and processors, facilitates the collection, matching, and transfer of fingerprint data via short-range wireless communication, allowing for seamless enrollment and authentication across devices without repeated processes, using NFC or Bluetooth transceivers for data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fingerprint matching techniques are used across multiple devices, then fingerprint identification accuracy is maintained, but enrollment process complexity and time consumption increase significantly
Solution Approach 1:
The patent creates a digital copy of the enrolled fingerprint data from the first device and transfers it to the second device via wireless communication. This copy allows the second device to perform fingerprint matching without requiring the user to re-enroll, thus maintaining identification accuracy while significantly reducing enrollment time and effort.
Solution Approach 2:
The system performs preliminary fingerprint enrollment on the first device, storing the biometric data securely. When the user obtains a second device, the previously enrolled fingerprint data is automatically or semi-automatically transferred, eliminating the need to perform the enrollment action again on the new device.
2Ease of operation
If fingerprint data is transferred between devices, then user convenience is improved, but data security and transmission reliability face challenges
Solution Approach 1:
The patent introduces an intermediary authentication mechanism where the transferred fingerprint data is verified and authenticated before being accepted by the second device. This intermediary step ensures that only authorized and valid biometric data is transferred, maintaining security while enabling convenient cross-device functionality.
Solution Approach 2:
The system transforms the fingerprint data into a secure transmission format with modified parameters (such as encryption encoding) during transfer between devices. This parameter change ensures the data remains secure during transmission while maintaining its biometric identification capabilities upon receipt.
3Adaptability or versatility
If multiple fingerprints are enrolled across multiple devices, then comprehensive biometric coverage is achieved, but enrollment complexity increases
Solution Approach 1:
The patent merges the fingerprint enrollment processes across multiple devices by allowing fingerprint data to be transferred and shared between them. Instead of treating each device's enrollment as a separate complex process, the system combines them into a unified enrollment experience where data from one device can supplement another, reducing overall complexity while maintaining comprehensive biometric coverage.

AI summary
An electronic system may include a first electronic device comprising a first finger biometric sensor, a first processor capable of collecting enrollment finger biometric data from the first finger biometric sensor, and a first short-range wireless transceiver coupled to the first processor. The system may further include a second electronic device comprising a second finger biometric sensor, a second short-range wireless transceiver, and a second processor capable of collecting to-be matched finger biometric data from the second finger biometric sensor, and downloading the enrollment finger biometric data from the first processor via a short-range wireless link between the first and second short-range wireless transceivers based upon the collected to-be matched biometric data.
