Fingerprint Unlocking with Environment Verification Against Pocket Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often unintentionally unlock due to accidental fingerprint detection when placed in pockets or bags, leading to potential malfunctions and security risks.
Innovation Solution
Implementing a dual-sensor system with a fingerprint sensor and an environmental sensor to authenticate fingerprint information and verify operation environment conditions before unlocking, ensuring the device remains locked if the environment does not meet predefined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint authentication is implemented for device unlocking, then security and convenience are improved, but accidental unlocking occurs when the device is placed in pockets or bags
Solution Approach 1:
The patent introduces an environmental sensor as an intermediary verification layer between the fingerprint sensor and the unlocking mechanism. The environmental sensor detects whether the device is in a pocket or bag environment, and only allows unlocking when both fingerprint authentication succeeds and the environmental conditions are appropriate. This mediator prevents accidental unlocking while maintaining convenient authentication.
2Reliability
If environmental verification is added to the unlocking process, then accidental unlocking is prevented, but system complexity increases
Solution Approach 1:
The environmental sensor serves multiple functions: it detects pocket/bag environments to prevent accidental unlocking, monitors device usage contexts, and works alongside the fingerprint sensor as part of a unified authentication system. By making the sensor multi-functional, the patent reduces the need for separate dedicated components and minimizes overall system complexity.

AI summary
A device unlocking method and an electronic device are provided. The method includes: detecting fingerprint information of a user by a first sensor of the electronic device; authenticating the fingerprint information and temporarily storing an authentication result of the fingerprint information; after authenticating the fingerprint information, detecting operation environment information related to the electronic device by a second sensor of the electronic device; and in response to the operation environment information meeting a default condition, unlocking the electronic device according to the authentication result.
