Wireless PAN LAN Theft Detection Using Mobile Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current theft prevention systems for surveillance targets, such as in stores, are ineffective in areas where cameras cannot capture images and fail to monitor stolen items that leave a specific area, leading to inadequate surveillance and detection of loss or theft.
Innovation Solution
A method and system utilizing a wireless personal area network (PAN) or wireless local area network (LAN) that receives location information from mobile devices via a gateway, collects sensor data from surveillance targets, compares this information with permission standards, and provides alert information, including location details, when theft is detected, enabling efficient associated surveillance across multiple networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surveillance cameras are installed, then surveillance capability is provided, but blind spots remain in dead zones where cameras cannot capture images
Solution Approach 1:
The patent replaces the mechanical/optical surveillance system (cameras) with a wireless communication-based system. Mobile devices equipped with sensors (GPS, accelerometer, etc.) transmit location and status data wirelessly to a server, eliminating the need for physical camera installations in hard-to-reach areas while providing comprehensive surveillance coverage.
Solution Approach 2:
The system allows any mobile device with sensing capabilities to function as a surveillance node. Instead of requiring dedicated surveillance hardware, ordinary mobile devices can perform surveillance functions by collecting sensor data and communicating location information, making the surveillance system universally applicable across various scenarios and locations.
2Reliability
If identification tags are adhered to products, then theft detection is enabled, but the system fails when tags are separated from products
Solution Approach 1:
The mobile device itself serves as the identification and surveillance unit. The device's built-in sensors (GPS for location, accelerometer for movement detection) and communication capabilities enable it to independently perform theft detection functions without relying on external tags that can be removed or separated from the monitored object.
Solution Approach 2:
The server acts as an intermediary that receives location and status data from mobile devices, compares it with predefined surveillance areas and permission standards, and determines whether theft has occurred. This centralized processing enables robust theft detection by analyzing patterns and contexts that would be difficult to achieve with simple tag-based systems.
3Reliability
If general theft prevention systems are used, then basic surveillance is provided, but associated surveillance of stolen items leaving specific areas cannot be performed
Solution Approach 1:
The system continuously receives location information feedback from mobile devices and compares it against surveillance area definitions and permission standards. When a device enters or leaves designated areas, the system provides real-time alerts and location data, enabling effective tracking of stolen items as they move through different locations.
Solution Approach 2:
The surveillance system dynamically adapts to the movement and location changes of monitored devices. Instead of static surveillance zones, the system can respond in real-time to device locations, adjusting surveillance parameters and providing location-based alerts that adapt to the dynamic behavior of potential stolen items.

AI summary
A method and system of preventing a loss/theft of a surveillance target including a mobile device using a wireless personal area network (PAN) or a wireless local area network (LAN) which can receive, from the mobile device included in the surveillance target via a gateway, location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile device information being collected by a sensor of the mobile device, and signal information communicated between the mobile device and a fixed device, can determine whether there is a loss or theft by comparing surveillance target information and a permission standard, and can provide alert information including the location information of the surveillance target when the loss or theft occurs.
