Cloud-Based Vehicle Data Security Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing vehicle accident records and determining the driving entity during accidents face challenges such as data loss, forgery, and privacy invasion due to limited memory capacity and external attacks, especially in cases of small accidents and with the increasing use of autonomous vehicles.
Innovation Solution
A cloud-based system that generates pseudonyms and pseudonym certificates for vehicles, securely stores vehicle state information including accident records and driving entity data, using integrity verification values and digital signatures to prevent data tampering, and assigns vehicle manufacturer identification for efficient data retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored in the event data recorder memory, then accident record information is preserved, but data may be damaged or changed due to illicit attempts and external attacks
Solution Approach 1:
The patent introduces a cloud-based event data recorder system as an intermediary between the vehicle's onboard systems and external investigators. The cloud server stores encrypted accident record information, acting as a secure mediator that prevents direct access to the vehicle's memory. This eliminates the vulnerability to illicit attempts while preserving data integrity through secure cloud storage and controlled access mechanisms.
2Quantity of substance
If memory capacity is limited in the event data recorder, then device size is reduced, but data loss occurs due to overwriting of small accident records
Solution Approach 1:
The patent transitions data storage from a single-dimension local memory system to a multi-dimensional architecture combining onboard memory with cloud-based storage. The cloud server provides virtually unlimited storage capacity in a different dimensional space, allowing retention of all accident records including small accidents without overwriting. This dimensional expansion resolves the contradiction between limited device capacity and information preservation.
3Ease of operation
If vehicle identification information is stored for accident investigation, then data retrieval is enabled, but privacy invasion occurs due to exposure of location history
Solution Approach 1:
The patent segments vehicle identification information into multiple components: permanent identifiers (vehicle identification number, manufacturer information) that remain constant, and temporary identifiers (pseudonyms) that change periodically. This segmentation allows investigators to retrieve accident data using pseudonyms without accessing permanent identification that could reveal location history and personal information, thus enabling data retrieval while preventing privacy invasion.
4Loss of information
If data is collected from multiple data sources individually, then comprehensive information is gathered, but time and expenses increase significantly
Solution Approach 1:
The patent merges multiple data collection functions into a single cloud-based event data recorder system. The cloud server automatically collects, stores, and manages accident record information from various vehicle sensors and systems in one centralized location. This eliminates the need for investigators to individually access multiple data sources, significantly reducing investigation time and expenses while maintaining comprehensive data collection.

AI summary
Disclosed herein are an apparatus and method for processing vehicle data security based on a cloud. The method may include requesting, by a vehicle, a cloud center device to register a cloud-based vehicle data security service; generating, by the cloud center device, cloud-based vehicle data security policies and a pseudonym for the vehicle; requesting, by the cloud center device, an authentication center to generate a pseudonym certificate for the pseudonym and receiving the pseudonym certificate; transmitting, by the cloud center device, the cloud-based vehicle data security policies, the pseudonym, and the pseudonym certificate to the vehicle; generating, by the vehicle, vehicle state information, including accident record information and driving entity information, based on the cloud-based vehicle data security policies and transmitting the same to the cloud center device; and storing, by the cloud center device, the accident record information and the driving entity information in a database for each vehicle.
