IoT Proximity Monitoring for Security Alert Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telework environments, ensuring security of IoT devices when they are out of the user's immediate proximity is a significant challenge, as existing systems lack effective mechanisms to monitor and respond to changes in device positioning and unauthorized access.
Innovation Solution
An information processing system comprising IoT devices and a monitoring server that utilize position sensors and communication units to calculate relative distances and transmit alerts when these distances exceed a predetermined limit, enabling security alerts and lockout mechanisms to prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position sensors and monitoring systems are implemented to detect device proximity, then security monitoring capability is improved, but device complexity increases
Solution Approach 1:
The monitoring server performs multiple functions including distance calculation, alert generation, and communication coordination within a single centralized system, eliminating the need for complex security logic in each IoT device while maintaining comprehensive security monitoring capability
Solution Approach 2:
A monitoring server acts as an intermediary between IoT devices and users, receiving position information from devices, calculating distances, and transmitting alerts to users without requiring direct complex interactions between devices and end users
2Loss of time
If real-time position monitoring and alert transmission are implemented, then security response time is improved, but energy consumption increases
Solution Approach 1:
The system transmits position information and monitors distance at periodic intervals rather than continuously, reducing energy consumption while maintaining timely security alert capability when devices move beyond the predetermined distance

AI summary
An information processing system includes a first device, a second device, and a notification unit. The first device includes a position sensor and a communication unit. The second device includes a position sensor and a communication unit. The notification unit transmits, in a case where a relative distance between the first device and the second device calculated based on positional information detected by the position sensors exceeds a limit value, an alert to at least one of the first device and the second device.
