Dynamic Security Level Adjustment via User Activity Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security management systems for restrictive areas rely heavily on physical devices like cameras and central control systems, which are costly and raise privacy concerns, and often require excessive security measures that inconvenience users, such as constant locking of doors and windows.
Innovation Solution
A method and system that determines a security level for accessing a restrictive area by collecting data from monitoring devices associated with users, such as wearable fitness trackers or mobile phones, to assess their activity and physical condition, dynamically adjusting the security level based on their ability to protect the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical security devices (cameras, central control systems) are deployed, then security protection capability is improved, but system cost and device complexity increase
Solution Approach 1:
The patent replaces traditional mechanical security devices (cameras, central control systems) with a mobile terminal-based security system. The mobile terminal's existing sensors (accelerometer, gyroscope, GPS) and processing capabilities are utilized to perform security monitoring functions, eliminating the need for complex dedicated security hardware while maintaining protection capability.
Solution Approach 2:
The patent makes the mobile terminal serve multiple functions: it acts as both a communication device and a security monitoring system. The same mobile terminal used for daily communication also performs security level determination, activity monitoring, and alert generation, eliminating the need for separate dedicated security devices.
2Reliability
If excessive security measures are implemented, then security protection capability is improved, but user convenience deteriorates
Solution Approach 1:
The patent implements dynamic security level adjustment based on real-time activity recognition. The security level is not fixed but changes dynamically according to the user's physical state (walking, running, stationary). When the user is active and able to respond, security measures are relaxed; when inactive or sleeping, security measures are automatically strengthened.
Solution Approach 2:
The patent changes security parameters (security level) based on detected activity parameters. The system monitors movement intensity, duration, and patterns, then adjusts security levels accordingly. This parameter-based adjustment allows the system to provide appropriate security without constant manual intervention or excessive fixed measures.
3Measurement precision
If continuous monitoring is performed, then security detection capability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic activity recognition instead of continuous monitoring. The system periodically checks for changes in physical state (movement, position, activity intensity) and only triggers security responses when changes are detected. This periodic approach maintains detection capability while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The patent uses the mobile terminal's existing sensors and processing capabilities to perform self-monitoring of physical activity. The device leverages its own accelerometer, gyroscope, and GPS data without requiring additional power-intensive monitoring hardware, achieving energy-efficient security detection through self-service utilization of available resources.
