Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in securely determining location information, particularly in indoor environments where GPS accuracy is limited and security and inaccuracy of indoor positioning systems remain unresolved.
Innovation Solution
An electronic device equipped with a radio communication module and a secure element, which receives beacon messages from beacon devices, determines location information using transmission properties, and stores it securely in the memory, enabling real-time location determination and secure transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used for outdoor location determination, then location information can be obtained, but accuracy is limited and indoor positioning is not feasible
Solution Approach 1:
The patent implements a universal positioning system that works across both indoor and outdoor environments by integrating multiple positioning methods (GPS for outdoor, beacon-based for indoor) into a single electronic device. The system automatically selects or switches between positioning methods based on environmental context, providing consistent location determination functionality regardless of whether the device is indoors or outdoors.
2Adaptability or versatility
If indoor beacon devices are installed for positioning, then indoor location can be determined, but security of the positioning system is compromised
Solution Approach 1:
The secure element acts as an intermediary component that mediates between the beacon message reception system and the location determination process. It securely stores cryptographic keys and authentication credentials, verifies the authenticity of beacon devices, and protects the positioning system from unauthorized access or manipulation while enabling continuous indoor location tracking.
Solution Approach 2:
The patent segments the positioning system into distinct functional components: beacon message reception, secure element for key storage and authentication, and location determination. This segmentation isolates security-critical functions in the secure element from the general positioning logic, allowing the system to maintain high security standards while providing versatile indoor positioning capability.
3Ease of operation
If location information is stored in general memory, then location data can be accessed, but security of location data is compromised
Solution Approach 1:
The secure element serves as an intermediary storage component that holds cryptographic keys and sensitive location data. It provides controlled access to location information, allowing the system to maintain security while enabling authorized access when needed for applications such as location-based services or emergency responses.
