Biometric Authentication for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fingerprint-verifying processes for electronic devices, such as smartphones, are time-consuming and troublesome for general users, as they require a specific unlocking procedure before normal operation can commence.
Innovation Solution
A method and system that capture biologic feature data during user input, determining whether it matches stored reference data to automatically switch the device from a locked to a non-locked state for authorized users, or vice versa, eliminating the need for additional unlocking procedures for authorized users while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fingerprint-verifying process is used, then security is maintained, but user operation becomes time-consuming and troublesome
Solution Approach 1:
The system performs preliminary fingerprint verification by capturing biologic feature data during normal input operations before the user actually needs to operate the device. This preliminary verification is done in the background, so when the user needs to perform an operation, the verification is already complete or being completed simultaneously, eliminating the need for separate unlocking steps.
Solution Approach 2:
The patent merges the fingerprint verification process with the normal input operation process. Instead of separating verification and operation into distinct steps, the system combines them by capturing biologic feature data during the input process itself, allowing verification and operation to occur simultaneously or in overlapping timeframes.
2Reliability
If fingerprint verification is required before operation, then security is ensured, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service verification by automatically capturing and verifying biologic feature data during normal input operations without requiring the user to consciously initiate a verification process. The verification happens automatically in the background, making the system serve itself rather than requiring active user participation in the verification step.
Solution Approach 2:
The verification is performed preliminarily during the input process itself, so when the user needs to operate the device, the verification is already complete or being completed simultaneously, eliminating the need for separate unlocking steps.
3Ease of operation
If biologic feature verification is performed during input operation, then user-identifying process is simplified, but system complexity increases
Solution Approach 1:
The input module is designed to serve multiple functions: it既可以 capture normal input data for operations,又可以 capture biologic feature data for verification. This multi-functionality eliminates the need for separate verification hardware, reducing overall system complexity while enabling simplified user identification.

AI summary
In a method of switching a locked state of an electronic device with a user-verifying function, a biologic feature data from a user is captured while receiving an input from the user for an operation when the electronic device is in a locked state. Whether the biologic feature data conforms to a reference biologic feature data is then determined. If it is determined that the biologic feature data conforms to the reference biologic feature data, the electronic device is switched from the locked state into a non-locked state and directly controls the electronic device to perform the operation according to the input when the biologic feature data is determined conforming to the reference biologic feature data.
