Community Cloud Route Navigation Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud navigation services compromise user privacy by requiring the sharing of personal location information with cloud service providers, which diminishes user autonomy and raises concerns about data security and trust.
Innovation Solution
A community cloud system where mobile navigation devices and community compute devices share route navigation data directly, allowing users to benefit from traffic information without transmitting personal data to public cloud service providers, thereby maintaining privacy and enhancing data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cloud navigation services are used to provide real-time routing information, then navigation accuracy and real-time traffic updates are improved, but user privacy and data security are compromised due to mandatory sharing of personal location information with cloud service providers
Solution Approach 1:
The patent introduces a peer-to-peer communication intermediary layer that enables navigation devices to share traffic information directly without transmitting personal location data to cloud service providers. This intermediary mechanism allows real-time routing information to be obtained while maintaining user privacy by acting as a mediator that filters out identifying information.
Solution Approach 2:
The patent extracts and removes personal identifying information from location data before sharing it with other users or cloud services. By separating the useful navigation information (traffic patterns, route optimization) from the sensitive personal data (exact location, device identifiers), the system maintains navigation accuracy while eliminating privacy risks.
2Productivity
If personal location information is shared with cloud service providers to enable cloud navigation services, then real-time routing information is obtained, but user autonomy is diminished through loss of control over personal data
Solution Approach 1:
The patent implements a self-service navigation system where devices autonomously obtain routing information from peer devices without requiring centralized cloud service provider mediation. Users maintain control over their data by selectively sharing information only with nearby devices, enabling real-time routing while preserving autonomy through decentralized, user-initiated data sharing.
3Measurement precision
If centralized cloud service providers collect and process location data from multiple devices, then comprehensive traffic information is obtained for route optimization, but data security risks increase due to centralized data storage
Solution Approach 1:
The patent segments the centralized cloud-based navigation system into distributed peer-to-peer communication units. Instead of one centralized data collection point, multiple navigation devices independently exchange traffic information locally, creating numerous small data nodes rather than one large vulnerable database. This segmentation maintains comprehensive traffic information accuracy while eliminating the single point of failure and reducing data security risks.

AI summary
Technologies for sharing route navigation data in a community cloud include a mobile navigation device of a vehicle and a remote mobile navigation device of a remote vehicle. The mobile navigation device generates sensor data associated with a current route of the vehicle and determines whether a reference traffic event occurs within a segment of the current route of the vehicle. In response to a determination that a reference traffic event occurs, the mobile navigation devices transmits route update data to the remote mobile navigation device. Based on the route update data, the remote mobile navigation device updates a current route of the remote vehicle to avoid the reference traffic event within a corresponding segment of the current route of the remote vehicle. The mobile navigation device may also transmit the sensor data to a community compute device, which may transmit route update data to the remote mobile navigation device.
