Solution Overview

Problem

First-generation vehicular communication technologies like ITS-G5 and LTE C-V2X face privacy concerns, potentially requiring removal or deactivation if these issues are not addressed.

Innovation Solution

A method involving the dynamic handling of traffic data by obtaining location and sensor data, blurring it by adding noise, and transmitting the blurred data to maintain privacy while ensuring traffic safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If location data and sensor data are transmitted without blurring, then traffic safety monitoring is improved, but user privacy is compromised

Engineering Contradiction:

Improvetraffic safety monitoringVSAvoidprivacy concerns

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces blurred data as an intermediary between raw sensor data and transmitted information. The blurring function acts as a mediator that preserves essential traffic safety information while removing personally identifiable details, thus protecting user privacy without completely sacrificing monitoring capability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies parameter changes by modifying the precision and accuracy parameters of location and sensor data through blurring operations. By adjusting the degree of blurring, the system can dynamically balance between privacy protection and traffic safety monitoring effectiveness

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If data blurring is applied to protect privacy, then user privacy is maintained, but measurement precision of location data deteriorates

Engineering Contradiction:

Improveprivacy protectionVSAvoidlocation data accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent applies partial action by selectively blurring only the portions of data that contain personal identifiers while preserving the essential spatial and temporal information needed for traffic safety analysis. This partial blurring approach maintains sufficient precision for safety monitoring without exposing private information

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method for dynamically handling traffic data can include obtaining location data and sensor data corresponding to at least one object located in a traffic area. The location data and/or the sensor data then can be selectively blurred to preserve privacy or meet privacy regulations. The blurring may be implemented by adding noise to the location data and/or the sensor data. The blurred data may then be transmitted to another entity.
