Vehicle Privacy Protection via Offset Reference Point for POI Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face challenges in providing occupants with information about points of interest while maintaining privacy regarding the vehicle's current location, as they need to communicate this location to remote sources to gather such information.
Innovation Solution
A method and system that determine vehicle geographic coordinates, select a reference point away from the current location, and request information about points of interest within a defined region from a remote provider, allowing the vehicle to receive and display this information without revealing its exact location by using a randomized adjustment to the coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle transmits its current location to a remote source to gather information about points of interest, then the occupant receives useful information, but the vehicle's location privacy is compromised
Solution Approach 1:
The patent introduces a virtual reference point as an intermediary between the vehicle's actual location and the remote information provider. Instead of transmitting the true current location, the system transmits coordinates of a reference point that is offset from the actual position by a predetermined distance. This intermediary mechanism allows the vehicle to obtain points of interest information without directly exposing its location privacy.
Solution Approach 2:
The system creates a virtual copy of the vehicle's location by generating reference coordinates that replicate the essential function of location transmission without revealing the true position. The reference point acts as a fictitious copy that satisfies the information provider's need for location data while protecting the actual vehicle location.
2Object-affected harmful factors
If the vehicle uses a reference point offset from its current location to protect privacy, then location privacy is maintained, but the accuracy of points of interest information may be reduced
Solution Approach 1:
The patent applies local quality by making the information retrieval highly localized around the reference point. The system requests points of interest within a specific radius or geographic area centered on the reference point, ensuring that even though the reference point is offset from the actual location, the returned information remains relevant and accurate for the vehicle's actual vicinity.
Data Source
AI summary
To obtain point of interest information in a vicinity of a vehicle, the vehicle selects a reference point away from the current location of the vehicle. A region is formed, including the current location of the vehicle, based on the reference point. Points of interest falling within the region are communicated to the vehicle.
