Privacy-preserving Coronavirus Real-time Map System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for virus infection location detection infringe on personal privacy by tracking and sharing users' geographic information, which is not acceptable to many individuals.
Innovation Solution
A real-time map system that locally stores users' geographic location data on their mobile phones, using GPS to detect approaching infected areas without sharing personal information, and provides routing options to avoid infected locations while maintaining user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS tracking and data sharing is implemented to detect virus infection locations, then the ability to detect and alarm infected areas is improved, but personal privacy protection deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism where users voluntarily report their location data only after testing positive for the virus. This intermediary step (virus test result) acts as a filter that allows the system to collect necessary infection location data without requiring continuous tracking of all users, thus maintaining privacy while enabling effective detection of infected areas.
Solution Approach 2:
The system employs self-service by requiring users to voluntarily submit their location data when they test positive. Instead of imposing continuous tracking on all users, the system relies on infected individuals to self-report their movement history, which then becomes useful data for warning other users. This approach minimizes privacy intrusion while maintaining detection effectiveness.
2Speed
If continuous GPS tracking is implemented to provide real-time location detection, then the real-time alarming capability is improved, but energy consumption and device complexity increase
Solution Approach 1:
Instead of continuous GPS tracking, the system uses periodic location recording triggered by specific events (when a user tests positive for the virus). The GPS records location data at periodic intervals during the user's movement, and this data is submitted only when needed (upon positive test result). This periodic approach provides sufficient data for real-time alarming without the continuous energy consumption of constant tracking.

AI summary
The present invention discloses a coronavirus real-time map to alarm users when approaching infected locations. The infected locations are updated in real-time based on the life cycle of the virus on surfaces, and the virus test results of the users. The data collected about the user's geographic locations are locally stored on the user's mobile phone to secure their personal privacy.
