Location-Based Anonymity Vault for Selective User Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based systems lack effective mechanisms for providing users with selective anonymity and privacy control, particularly in defining regions where personal information is revealed or concealed.
Innovation Solution
The system introduces selective anonymity by defining regions on a map where users can choose to be anonymous or reveal personal information, using a 'vault' for storing and managing user data, and implementing last known location tracking to maintain privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users transmit information to a broad group of recipients, then information availability is improved, but user privacy and anonymity deteriorate
Solution Approach 1:
The system segments the recipient list into targeted subsets based on location criteria. Instead of broadcasting to a broad group, the system identifies and transmits only to computing devices within specific geographic regions, thereby maintaining information availability while protecting user privacy through selective distribution.
Solution Approach 2:
The system implements location-based filtering that creates different information access qualities based on geographic location. Users within defined regions receive full information, while users outside regions receive limited or no information, enabling privacy protection through spatial differentiation of service quality.
2Adaptability or versatility
If the system tracks user locations continuously, then location-based service functionality is improved, but user anonymity deteriorates
Solution Approach 1:
The system dynamically adjusts tracking behavior based on user location relative to defined regions. Tracking is activated only when users enter designated areas where location-based services are needed, and deactivated when users are outside these regions, maintaining service functionality where required while preserving anonymity elsewhere.
Solution Approach 2:
The system pre-defines geographic regions where location tracking and service functionality are enabled. By establishing these regions in advance, the system can selectively activate tracking only when necessary, avoiding continuous monitoring and thus preserving user anonymity during periods when services are not needed.
3Loss of information
If the system stores comprehensive user information, then information retrieval capability is improved, but privacy security deteriorates
Solution Approach 1:
The system extracts and stores only the minimal necessary information required for location-based services. Instead of maintaining comprehensive user profiles, the system stores limited data such as current location and region membership status, thereby improving information retrieval capability for service delivery while minimizing privacy security risks through data minimization.
Solution Approach 2:
The system implements temporary storage of user information that is discarded when no longer needed. Location data is stored only during active service periods and is deleted when users exit defined regions or sessions end, maintaining information retrieval capability for ongoing services while enhancing privacy security by eliminating persistent storage of comprehensive user information.

AI summary
Implementations of enhancing privacy and anonymity for users of a computer system are provided. For example, selective anonymity for one or more users may be provided in which the one or more users may be anonymous or not, with various degrees of anonymity in between. A “vault” or other information repository may be used to save information (e.g., all information retained, all or a portion of privacy-related or personally-identifiable information) about a user that can be accessed by the user to see, reset, and or delete all or a portion of the information that is saved on the system. Further, “last known location” information may be kept, such that, in some implementations, the last known location (or a limited number of most recent locations) of a user may be kept such that historical information and/or a route of a user is not stored on the system.
