Location-Based Service Zone Control for Privacy

The patent segments location-based information into different categories and types, allowing users to selectively enable or disable specific types of information. Instead of treating all location-based information as a single unit, the system divides it into manageable segments that can be independently controlled, giving users granular access control over what location information they receive.

The patent applies local quality by allowing different levels of location precision to be used in different contexts or for different types of information. Instead of using a single global location precision level, the system enables users to specify varying degrees of location detail (e.g., exact coordinates for some services, generalized area for others) based on their privacy preferences and the specific information needs of different location-based services.

The patent implements preliminary action by enabling users to download and store location-based information locally on their devices in advance, before needing to access it. This pre-fetching and local caching mechanism ensures that even when the remote server is unavailable, users can still access previously downloaded location information, thereby maintaining service reliability and availability independent of server status.

The patent uses the mobile device itself as an intermediary between location data and peer-to-peer communication. Instead of requiring a central server to mediate all location-based information sharing, each device processes and manages its own location information locally, then shares relevant location data directly with other devices. This eliminates the need for complex server-mediated coordination while maintaining ease of operation through localized decision-making.
