Biometric Authentication Device Using Pre-Registered External Sensor Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face challenges in efficiently acquiring biometric data for user authentication from external devices equipped with medical sensors, as they must attempt coupling with multiple peripherals, leading to prolonged authentication times due to the inability to determine which device to acquire data from.
Innovation Solution
An electronic device that searches and selects an external electronic device for biometric authentication based on pre-registered information, using short-range communication protocols to couple with available devices, prioritize them, and transmit biometric authentication requests, thereby optimizing the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic device attempts coupling and requests biometric data to all peripheral external electronic devices, then the probability of successfully acquiring biometric data increases, but the authentication time becomes very long
Solution Approach 1:
The system performs preliminary actions by pre-registering biometric authentication information and device identification information from external electronic devices before authentication is needed. This allows the electronic device to have a ready list of trusted external devices, eliminating the need to attempt coupling with all peripheral devices during authentication and significantly reducing authentication time while maintaining reliability
Solution Approach 2:
The system creates a copy of biometric authentication information and device identification information from external electronic devices and stores it locally in the electronic device. This copied information enables rapid authentication by comparing against stored copies rather than attempting real-time coupling with multiple devices
2Adaptability or versatility
If an electronic device does not have a medical sensor, then it can still perform user authentication by acquiring biometric data from external devices, but it cannot determine from which peripheral external device to acquire biometric data
Solution Approach 1:
The system uses device identification information as an intermediary to bridge the gap between the electronic device without medical sensors and external devices with medical sensors. By storing and matching device identification information, the system can accurately identify which external device to request biometric data from, eliminating the complexity of determining device selection

AI summary
The present disclosure relates generally to a device and method for performing authentication using biometric data in an electronic device. The electronic device can include a memory for storing biometric authentication information about one or more external electronic devices and one or more identification information corresponding to each of the one or more external electronic devices, the one or more external electronic devices including sensors configured to acquire biometric data corresponding to the biometric authentication information, and a processor. The processor can be configured to receive a request related with authentication, to select at least one external electronic device from among the one or more external electronic devices in relation with the authentication, to transmit a request for authentication to the at least one external electronic device, using at least one identification information corresponding to the at least one external electronic device from among the one or more identification information, and to perform the authentication based at least on authentication information received from the at least one external electronic device and the biometric authentication information.
