Passive Mobile Device Detection via Captive Portal Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Property owners in rental properties face challenges in monitoring their properties without infringing on guests' privacy, as unauthorized individuals often enter, causing damage or reputational issues, and existing solutions are either invasive or overly burdensome for management.
Innovation Solution
A system using network transceivers disguised as hotspots to detect and track mobile devices without installed applications, collecting data on unique IDs, presence, history, and frequency of visits, and integrating with security systems to trigger notifications or actions based on predefined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If network transceivers disguised as hotspots are used to detect mobile devices, then monitoring capability is improved, but guest privacy is compromised
Solution Approach 1:
The patent introduces an intermediary layer (captive portal and server) between the monitoring system and the guest's mobile device. The transceiver collects device identifiers and passes them through a captive portal mechanism to a server, which processes the information without requiring direct guest interaction or awareness, thus enabling monitoring while maintaining a degree of privacy buffer
Solution Approach 2:
The patent extracts only the essential identifying information (device identifier/MAC address) from the mobile device without capturing more intrusive data. By taking out only the minimum necessary data element for monitoring purposes, the system reduces privacy infringement while maintaining monitoring capability
2Reliability
If traditional monitoring systems are deployed, then security is improved, but ease of operation deteriorates due to installation burden
Solution Approach 1:
The monitoring system leverages the guest's own mobile device and its automatic wireless network scanning behavior to perform the detection function. The transceiver merely needs to broadcast a hotspot signal, and the guest's device automatically connects and reveals its identifier, eliminating the need for manual installation on guest devices or complex setup procedures
Solution Approach 2:
The patent uses a universal approach by leveraging the captive portal mechanism that is inherently supported by virtually all mobile devices and wireless networks. This multi-functional mechanism serves both as a network access control method and as a data collection point, eliminating the need for device-specific installation while maintaining security
Data Source
AI summary
Disclosed is a technique for passively monitoring the number of guests in a rental property. Mobile device broadcasts intended for connecting the device to a wireless network contain information about that device. This information includes unique identifiers such as MAC addresses. Detecting these broadcasts and filtering out those devices that are expected enables a property owner to have a semi-accurate number of guests within their property without actually being at the property, or visibly observing the guests in an obtrusive fashion. Guests are able to enjoy themselves in privacy and the property owner is able to monitor the safety of their property.
