Wireless Device Detection via Message Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring and controlling wireless devices in home or business environments lack efficient methods to detect and respond to unauthorized devices, and fail to provide personalized actions based on registered device presence or absence, leading to potential security breaches and inefficient resource management.
Innovation Solution
A system that intercepts and logs identifying information from wireless devices, using a controller to determine the presence or absence of registered devices, and triggers actions based on predefined scenarios, including security responses and home automation settings, without requiring explicit device connection or GPS tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system monitors wireless devices to detect unauthorized access, then security is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential identifying information (MAC address, device name) from wireless device messages without requiring full device analysis or connection establishment. This selective extraction enables security monitoring while minimizing system complexity and resource consumption.
Solution Approach 2:
The system uses an intermediary approach by capturing wireless messages as they pass through the network infrastructure. Instead of directly analyzing each device, the system intercepts and logs messages containing device identifiers, simplifying the monitoring process while maintaining security effectiveness.
2Adaptability or versatility
If the system logs and analyzes wireless device information to trigger personalized actions, then adaptability is improved, but measurement precision requirements increase
Solution Approach 1:
The system performs partial analysis by logging only specific identifying fields from wireless messages rather than capturing complete device profiles or continuous monitoring data. This partial action approach enables personalized automation responses while reducing the precision requirements for device identification and analysis.
Solution Approach 2:
The system performs preliminary logging of device identifiers and message metadata before triggering any automated responses. This preliminary data collection enables adaptability to multiple scenarios (security alerts, automation triggers, analytics) without requiring high-precision real-time analysis, as the logged data provides sufficient information for various purposes.
3Reliability
If the system continuously monitors wireless devices for security threats, then reliability is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic monitoring by capturing wireless messages at discrete intervals rather than continuous analysis. The controller logs identifying information from messages that pass through the network, which occurs periodically as devices communicate, thereby reducing energy consumption while maintaining effective security monitoring.
Solution Approach 2:
By extracting only essential identifying information (MAC address, device name, timestamp) from wireless messages rather than analyzing complete device states or continuous traffic patterns, the system achieves reliable security monitoring with minimal energy consumption. This selective extraction reduces processing requirements and battery power usage.

AI summary
Messages from wireless devices are intercepted by a controller, such as an access point for a wireless network, a security system controller, a home automation controller, an industrial or business automation controller, or a combination thereof. The controller logs device-identifying information about the devices that sent the messages that that were intercepted. Examples of the device-identifying information include a MAC address, a device name, a brand of the device, an SSID of an AP connected to the device, or a class of device. The intercepted message is used to trigger one or more events, either based solely on intercepting the message or in combination with other parameters.
