Solution Overview

Problem

The increasing use of Advanced Driver Assistance Systems (ADAS) and autonomous driving functions in vehicles has led to a demand for comprehensive data collection to analyze accident causes, while ensuring privacy protection for individuals, especially with the implementation of regulations like GDPR.

Innovation Solution

A method and system where vehicles generate pseudonymized identifiers for driver and vehicle data using hash functions and salts, allowing for secure transmission of pseudonymized vehicle-generated data to a neutral data server, independent of vehicle manufacturers, thereby protecting personal privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vehicle data is collected and stored in data servers for various services and research purposes, then the utility and value of vehicle data is improved, but personal privacy protection deteriorates

Engineering Contradiction:
Improvedata utilizationVSAvoidprivacy risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts personally identifiable information (PII) from vehicle data and stores it separately in secure PII storage, while the actual vehicle data is stored in data servers without direct links to individual identities. This separation allows data utilization while protecting privacy by removing the harmful identifying elements from the accessible data pool.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces pseudonymization as an intermediary mechanism that transforms identifying information into non-identifying pseudonyms. This mediator layer allows data to be used for services and research while preventing direct identification of individuals, thus resolving the contradiction between data utility and privacy protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If pseudonymized vehicle data is stored in neutral data servers, then privacy protection is improved, but data accessibility for authorized entities deteriorates

Engineering Contradiction:
Improveprivacy protectionVSAvoiddata accessibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent performs pseudonymization as a preliminary action before storing vehicle data in neutral data servers. By pre-processing the data to remove identifying information, the system ensures privacy protection is built-in from the start, while authorized entities can still access and use the pseudonymized data without needing to break privacy protections.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic access control where data accessibility changes based on authorization status. Authorized entities with proper credentials can access and link pseudonymized data to specific vehicles through the PII storage system, while unauthorized entities see only protected pseudonymized data. This dynamic approach balances privacy protection with authorized accessibility.

Inventive Principle:
Principle #15Dynamics

AI summary

A system for collecting and managing vehicle-generated data from multiple vehicles are provided. The vehicle-generated data is pseudonymized by pseudonymized identifiers, and the pseudonymized vehicle-generated data is collected and managed by a neutral data server operated by an operator who is independent of vehicle manufacturers. Vehicle manufacturers can reestablish the link of the pseudonymized event data with the vehicle that had generated the event data and the vehicle driver.
