POI Information Filtering for Privacy-Safe Location Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in generating and providing sensitive Point of Interest (POI) information unintended by the user, leading to privacy concerns and inconvenience when manual deletion or withdrawal of location services is required.
Innovation Solution
The device includes a processor that filters sensitive location and POI information using security configuration information and mapping tables to prevent the generation and transmission of sensitive data, while allowing non-sensitive information to be converted and shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device converts location information into POI information, then the user can easily search and find results, but sensitive POI information may be generated unintended by the user
Solution Approach 1:
The system performs preliminary filtering of location information before converting it to POI information. By checking whether refined location information matches sensitive information in advance, the system prevents the generation of sensitive POI data before it can cause privacy issues, while still allowing normal POI conversion to proceed for non-sensitive locations.
Solution Approach 2:
The system extracts and removes sensitive information from the location data processing pipeline. By identifying and filtering out sensitive location information before POI conversion, the system separates sensitive from non-sensitive data, ensuring only appropriate information is converted to POI format and transmitted.
2Object-affected harmful factors
If the user manually deletes sensitive POI information, then privacy is protected, but it is not possible to prevent the generation of sensitive POI information in advance and there are inconveniences
Solution Approach 1:
Instead of requiring users to manually delete sensitive POI information after generation, the system performs preliminary filtering of location information before POI conversion. This proactive approach prevents sensitive information from being generated in the first place, eliminating the need for manual deletion and associated user inconvenience.
Solution Approach 2:
The system implements automatic filtering mechanisms that operate without user intervention. The processor automatically refines location information, checks against sensitive information databases, and filters out sensitive data before POI conversion, replacing the need for manual user actions with automated self-service functionality.
3Object-affected harmful factors
If the consent of the location information providing service is withdrawn, then sensitive POI information is prevented from being generated, but the location information service may not be provided to the user
Solution Approach 1:
The system extracts only the necessary non-sensitive components from location information processing. By filtering out sensitive information while retaining and processing non-sensitive location data, the system maintains location information service functionality without requiring complete withdrawal of consent, thus preserving service availability.
Solution Approach 2:
The system applies different quality standards to different portions of location information. Sensitive information is filtered out with strict privacy protection, while non-sensitive location information continues to be processed and converted to POI information, allowing the service to remain available for appropriate locations.
4Adaptability or versatility
If the electronic device transmits POI information to external devices, then information sharing is enabled, but sensitive information may be shared inadvertently
Solution Approach 1:
The system extracts and removes sensitive information from POI data before transmission to external devices. By filtering sensitive information at the output stage, the system enables continued information sharing functionality while preventing privacy leakage in transmitted data.
Solution Approach 2:
The system uses feedback from sensitive information databases to guide the filtering process. By continuously checking refined location information and generated POI information against sensitive information records, the system dynamically adjusts what information is transmitted, enabling safe information sharing with feedback-driven privacy protection.

AI summary
An electronic device is provided. The electronic device includes a global positioning system (GPS) module, a communication module, and a processor functionally connected to the GPS module and the communication module. The processor is configured to obtain second location information by refining the first location information, when the second location information is first sensitive information, filter the second location, and when the second location information is not the first sensitive information, convert the second location information into point-of-interest (POI) information on the basis of a mapping table, when the POI information is second sensitive information, filter the POI information, when the POI information is not the second sensitive information, transmit the POI information to an external electronic device through the communication module, and receive update information from the external electronic device in response to the transmission of the POI information.
