Terminal Unlocking via Wearable Motion Data Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent wearable devices and terminals face challenges in preventing unauthorized state switching, leading to potential information leakage when users are close to each other, as existing solutions fail to accurately differentiate between genuine and unauthorized state switching instructions.
Innovation Solution
A control method that involves sending a motion data obtaining request to an intelligent wearable device, calculating the deviation between the device's and the terminal's motion data within a predetermined time period, and only responding to state switching instructions if the deviation is below a threshold, thereby reducing the likelihood of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal uses Bluetooth module to identify bound intelligent wearable device for state switching, then the terminal can be conveniently controlled by the wearable device, but information leakage occurs when another user enters an unlocking instruction nearby
Solution Approach 1:
The patent introduces motion data as an intermediary verification factor between the Bluetooth identification and the state switching execution. The terminal compares motion data from the wearable device with motion data from the terminal itself to verify authorization, adding a physical verification layer that prevents unauthorized access while maintaining convenient control for authorized users
2Speed
If the terminal responds to state switching instructions based on Bluetooth proximity, then the response speed is fast, but unauthorized users can trigger state changes when close by
Solution Approach 1:
The patent performs preliminary verification by comparing motion data before executing the state switching instruction. The terminal obtains motion data from both the wearable device and itself, calculates deviation, and verifies authorization before responding to the unlocking instruction, ensuring that only authorized users can trigger state changes while maintaining rapid response for valid requests
3Reliability
If the terminal uses motion data comparison for authorization, then information security is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes the terminal's existing motion sensing capabilities to generate verification data, making the system self-sufficient. The terminal compares its own motion data with data from the wearable device, eliminating the need for additional external verification hardware and reducing overall system complexity while maintaining strong security
Data Source
AI summary
A control method for controlling terminal state switching includes a terminal obtaining first data of the terminal and second data from a wearable device that is bound to the terminal when receiving an unlocking instruction in a lock screen state. If the first data and the second data meet a preset condition, the terminal performs the operation of unlocking.
