Beacon Device Location Compliance Detection for Neighbor Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing neighbor awareness technology faces security issues due to the ease of manual movement of beacon devices, leading to incorrect location detection and subsequent inappropriate information being pushed to users.
Innovation Solution
Implementing a compliance detection method that compares first location feature information with registration location feature information to determine if neighbor awareness should be triggered, preventing manual movement of beacon devices by associating neighbor awareness with location detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beacon devices are adhesively deployed and can be manually moved, then the device can be easily installed and repositioned, but the security and reliability of location-based neighbor awareness deteriorates
Solution Approach 1:
The system performs preliminary registration of location feature information when the beacon device is first deployed at its intended location. This registered information serves as a baseline for later compliance detection, preventing the device from being moved without detection while maintaining ease of initial installation.
Solution Approach 2:
The system continuously compares current location feature information with the registered baseline information to detect any movement of the beacon device. This feedback mechanism ensures that any unauthorized movement is detected and can trigger appropriate responses, thereby maintaining security while allowing legitimate repositioning through proper procedures.
2Reliability
If location feature information is continuously monitored and compared, then the security against beacon device movement is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The beacon device utilizes existing sensors and environmental detection capabilities that are already present in the device for other purposes. By repurposing these existing components for location compliance detection, the system avoids adding significant complexity while achieving the security goal.
Solution Approach 2:
The beacon device performs self-detection of its location by comparing its current environmental features with registered baseline information. This self-service approach eliminates the need for complex external monitoring infrastructure, reducing overall system complexity while maintaining security.
3Measurement precision
If location compliance detection is performed by comparing registered location feature information with current information, then the accuracy of location detection is improved, but the loss of time for information processing increases
Solution Approach 1:
The system performs compliance detection selectively rather than continuously at full capacity. It uses partial comparisons focused on key location features that are most indicative of device movement, achieving sufficient accuracy without the full time cost of exhaustive analysis of all environmental parameters.
Data Source
AI summary
A beacon device obtains first location feature information that indicates an environmental condition around a current location of the beacon device; obtains registration location feature information that indicates an environmental condition around an original assembly location of the beacon device; then compares the two pieces of information to perform compliance detection on a location of the beacon device; and determines, based on a detection result, whether to trigger neighbor awareness.
