Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biometric recognition systems face security vulnerabilities due to the separation of sensors and processing devices, where leaked sensing data can expose users' unique body characteristics, which cannot be changed like passwords.
Innovation Solution
An electronic device and method that acquire biometric information, determine virtual biometric information, and transmit it securely to an external device, enhancing security by using virtual biometric information for authentication instead of actual data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional biometric recognition systems transmit actual biometric sensing data to processing devices, then authentication can be performed, but security is compromised because leaked sensing data exposes users' unique body characteristics that cannot be changed
Solution Approach 1:
The patent applies the copying principle by creating virtual biometric information that replicates the authentication functionality of actual biometric data without exposing the real biometric characteristics. The virtual biometric information serves as a secure copy that can be transmitted and processed, while the original biometric data remains protected in the user device.
Solution Approach 2:
The patent implements the intermediary principle by introducing virtual biometric information as a mediator between the user's actual biometric data and the authentication processing system. This intermediary layer enables authentication to proceed while preventing direct exposure of the sensitive biometric characteristics.
2Ease of operation
If biometric sensors are separated from processing devices, then device flexibility and ease of operation improve, but security vulnerabilities increase due to potential leakage of sensing data during transmission
Solution Approach 1:
The patent uses the copying principle to create virtual biometric information that can be securely transmitted between separated sensor and processing devices. This allows the system to maintain flexibility and ease of operation with distributed architecture while preventing security vulnerabilities associated with transmitting actual biometric data.
Solution Approach 2:
The virtual biometric information acts as an intermediary that enables secure communication between separated biometric sensors and processing devices, maintaining system flexibility while eliminating the security risk of direct biometric data transmission.
3Measurement precision
If actual biometric data is transmitted for authentication, then authentication accuracy is maintained, but the system becomes vulnerable to attacks and data breaches
Solution Approach 1:
The patent applies the copying principle by transmitting virtual biometric information instead of actual biometric data. This maintains authentication accuracy because the virtual data preserves the necessary verification properties, while simultaneously eliminating system vulnerability since the copied data can be revoked and regenerated without affecting the user's real biometric characteristics.

AI summary
An electronic device includes a processor and a memory functionally connected to the processor. The electronic device acquires user's biometric information through a biometric sensor, determines virtual biometric information corresponding to the acquired biometric information, and transmits the virtual biometric information to an external electronic device through communication circuitry. The electronic device may include the biometric sensor, the communication circuitry, and the memory may be electrically connected to the biometric sensor and the communication module and store instructions to be executed by the processor.
