Vehicle Rider Authentication via Blockchain Biometric Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in authenticating riders and accurately billing users, as biometric data must be securely stored and transmitted, and existing cloud-based systems are vulnerable to hacks and data interception.
Innovation Solution
A blockchain-based system for autonomous vehicle rider authentication, where biometric data is processed locally, and authentication requests are transmitted via a private blockchain, using a recognition neural network to verify identities, ensuring decentralized and secure data storage and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric data is stored and transmitted in cloud-based systems, then authentication functionality is achieved, but security vulnerability increases due to hacks and data interception
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between the authentication system and data storage. Instead of directly storing biometric data in vulnerable cloud systems, the system uses blockchain nodes to verify and record authentication transactions. This intermediary blockchain network provides security through its decentralized consensus mechanism, preventing direct hacking of authentication data while maintaining verification functionality.
2Device complexity
If centralized cloud systems are used for authentication, then system simplicity is maintained, but security and decentralization are compromised
Solution Approach 1:
The patent segments the authentication system into multiple independent blockchain nodes distributed across the vehicle fleet rather than a single centralized cloud server. Each node maintains a copy of the authentication ledger and can independently verify transactions. This segmentation eliminates the single point of failure in centralized systems while distributing security responsibilities across multiple entities, thereby improving reliability without requiring complex centralized infrastructure.
3Measurement precision
If biometric data is transmitted to verify identity, then authentication accuracy is achieved, but data breach risk increases
Solution Approach 1:
The patent extracts and separates the biometric data from the authentication verification process. Instead of transmitting raw biometric data across the network, the system extracts only the essential authentication credentials needed for verification. The actual biometric templates remain stored locally in secure enclaves within each vehicle's onboard system, while only hashed or encrypted verification tokens are transmitted to blockchain nodes for validation. This extraction minimizes data exposure while maintaining verification accuracy.
Data Source
AI summary
Systems, methods, and devices for verifying an identity of a user of a vehicle. The method includes receiving user authentication data from a vehicle sensor and generating a transaction token comprising the user authentication data. The method includes transmitting the transaction token to a blockchain database. The method includes receiving a message from the blockchain database comprising one or more of: a request for additional user authentication data; or an indication that a rider authentication server has verified the identity of the user.
