Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems face challenges in securely and efficiently transmitting vehicle data from mobile objects to service providers without compromising user privacy and data security.

Innovation Solution

A mobile object and authentication system that includes a mobile object equipped with a receiver, obtainer, and transmitter. The system adds authentication information, such as user IDs and vehicle signatures, to vehicle data before transmission to a second server, which performs authentication using stored authentication information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vehicle data is transmitted to service providers without authentication, then data transmission efficiency is improved, but data security and user privacy are compromised

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoiddata security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs authentication information addition in advance before data transmission. The mobile object adds both first authentication information (for the second server) and second authentication information (for the first server) to the vehicle data beforehand, enabling the second server to quickly forward the data without performing authentication, thus maintaining security while improving transmission efficiency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The second server acts as an intermediary that receives authenticated data from the mobile object and forwards it to the first server. The second server stores authentication information and verifies it, but does not perform the final authentication itself - this intermediary role separates the authentication burden from the data transmission path, improving overall system efficiency while maintaining security

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multiple authentication information are added to vehicle data, then data security is improved, but device complexity increases

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system is segmented into two independent authentication layers: first authentication information (vehicle ID, signature) for the second server, and second authentication information (user ID, signature) for the first server. Each layer operates independently with its own verification process, making the complex authentication system manageable through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mobile object is designed with multi-functionality to handle both authentication types. It can add first authentication information for general data collection purposes and second authentication information for specific service provision purposes, making the same device capable of supporting multiple authentication scenarios without requiring separate systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If authentication information is added before transmission, then data integrity is improved, but processing time increases

Engineering Contradiction:

Improvedata integrityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication information addition process is integrated into the normal data collection and transmission workflow of the mobile object. Rather than being a separate post-processing step, the authentication is continuously performed as part of the data preparation process, minimizing additional processing time and maintaining continuous operational flow

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A mobile object includes: a receiver that receives first authentication information transmitted by a first server that stores second authentication information from the mobile object, the first server being for providing a service contracted by a user of the mobile object; an obtainer that obtains mobile object data of the mobile object; and a transmitter that transmits, to a second server that collects mobile object data, the mobile object data to which third authentication information and the first authentication information have been added, the third authentication information being used for authentication using the second authentication information, wherein the first server stores fourth authentication information used for authentication using the first authentication information.
