Mobile Terminal Authentication Triggered by Connection Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems consume excessive power due to continuous monitoring for user movement, which is inefficient and may lead to unauthorized access.
Innovation Solution
Implementing an authentication system that only performs state determination after receiving a connection request signal, reducing unnecessary state checks and power consumption by optimizing sensor data acquisition and determination processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous monitoring for user movement is performed, then authentication security is improved, but power consumption increases
Solution Approach 1:
The system performs state determination periodically or event-driven rather than continuously. The mobile terminal determines user presence state only when triggered by specific events (connection requests, authentication requests) rather than monitoring continuously, thereby reducing power consumption while maintaining security.
Solution Approach 2:
The mobile terminal autonomously determines the user presence state using its own sensors and resources without requiring continuous external monitoring. The terminal itself performs the authentication logic and state determination, eliminating the need for persistent external surveillance while maintaining security.
2Reliability
If state determination is performed continuously, then unauthorized access is prevented, but power consumption increases
Solution Approach 1:
State determination is performed periodically or on-demand rather than continuously. The system checks user presence state at specific intervals or when authentication events occur, maintaining security against unauthorized access while significantly reducing the power consumption associated with continuous monitoring.
Solution Approach 2:
The mobile terminal preliminarily determines the user presence state before authentication operations are executed. By performing state determination in advance when needed (rather than continuously), the system prepares authentication data only when necessary, preventing unauthorized access while conserving power.
3Use of energy by moving object
If sensor data acquisition is optimized to reduce power consumption, then energy efficiency is improved, but authentication reliability may deteriorate
Solution Approach 1:
Sensor data acquisition is performed periodically or event-driven rather than continuously. The mobile terminal acquires sensor data only when authentication events occur or at predetermined intervals, maintaining authentication reliability by ensuring data is collected when needed while improving energy efficiency through reduced sampling frequency.
Solution Approach 2:
The system changes the parameters of sensor data acquisition, such as sampling frequency and data collection intervals, based on authentication requirements. By dynamically adjusting acquisition parameters rather than using fixed continuous sampling, the system maintains sufficient data quality for reliable authentication while reducing overall power consumption.
Data Source
AI summary
An authentication control includes a connection authentication and an operation authentication for an authentication target device using a mobile terminal and a communication device that receives a signal from the mobile terminal toward the authentication target device. Information received by a reception unit in the mobile terminal and information detected by a state sensor for detecting a state of the mobile terminal are acquired. A connection response signal is transmitted from a transmission unit in the mobile terminal when the state of the mobile terminal satisfies a permission condition. A state determination for determining the state of the mobile terminal is performed after the reception unit receives the connection request signal.
