Blockchain vehicle identity authentication and request management

Blockchain vehicle identity authentication and request management

Term definitionBlockchain is a distributed database that uses encryption technology to ensure data security and immutability. Smart contracts are codes stored on the blockchain and automatically executed when preset conditions are met. IoT devices refer to physical devices that can exchange data over the network, such as vehicles. Sensor data is data collected by sensors on IoT devices, such as the fuel level and mileage of a vehicle. Fingerprint access data is a numerical value generated based on sensor data and is used to verify device identity and authorize requests. Blockchain nodes are computers that participate in maintaining the blockchain network, such as miner nodes and verification nodes. Machine accounts are blockchain accounts bound to specific IoT devices that can store and manage digital assets. Microtransactions refer to transactions with very small amounts, such as a small amount of fuel deducted for each refueling. Throughput refers to the number of requests processed per unit time, such as the number of transactions processed per minute. Streaming settlement refers to real-time processing and settlement of transactions without waiting for batch processing. Short answer questions

Briefly describe the vehicle identity authentication method proposed in this patent. (2-3 sentences) This patent uses vehicle sensor data to generate fingerprint access data as the basis for vehicle identity authentication. This method collects sensor data such as the vehicle's fuel level, mileage, and location, and generates a unique fingerprint value based on a preset algorithm to verify the vehicle's identity and authorize requests.

What elements does fingerprint access data contain? What are their respective functions? (2-3 sentences) Fingerprint access data includes granular value data, global warning data, and error flag data. Granular value data is calculated based on sensor data and reflects the consistency of vehicle data; global warning data records the frequency of suspicious events and is used to identify potential risks; error flag data is set when serious anomalies are detected and is used to directly reject requests.

What role do smart contracts play in vehicle service request management? (2-3 sentences) Smart contracts define the rules and logic of vehicle service requests, such as the fingerprint access data thresholds required for different request types, conditions for automatic approval or manual approval, etc. Blockchain nodes verify requests according to the provisions of smart contracts and perform corresponding operations, such as recording transactions, updating status, etc.

Explain the concept of machine accounts and their application in vehicle services. (2-3 sentences) Machine accounts are blockchain accounts bound to specific vehicles that can store and manage digital assets, such as prepaid fuel costs, insurance premiums, etc. Vehicle service providers can complete payments by accessing the vehicle's machine account without manual intervention, which improves efficiency and automation.

What are the advantages of streaming settlement over traditional settlement methods? (2-3 sentences) Streaming settlement can process and settle transactions in real time without waiting for batch processing, which improves transaction speed and efficiency. Traditional settlement methods usually require batch processing of transactions, which has problems of delay and inefficiency, especially when processing micro-transactions.

Explain the concept of blockchain network throughput and its impact on vehicle services. (2-3 sentences) Blockchain network throughput refers to the number of requests that can be processed per unit time, such as the number of transactions processed per minute. If the number of vehicle service requests exceeds the throughput of the blockchain network, it will cause network congestion, transaction delays and other problems, affecting service quality and user experience.

What is the role of the vehicle service request sorting method proposed in this patent? (2-3 sentences) This method monitors the blockchain network throughput, sorts and buffers vehicle service requests, ensures that the number of requests does not exceed the network load, ensures the stability and reliability of the service, and avoids problems such as network congestion and transaction delays.

Give an example of how to use vehicle sensor data to determine whether the vehicle has been refueled. (2-3 sentences) It can be judged by comparing the vehicle's oil sensor data and mileage sensor data before and after refueling. If the vehicle's oil sensor data increases after refueling, and the mileage sensor data does not change abnormally, it can be judged that the vehicle has refueled.

How does vehicle fingerprint access data help prevent fraud? (2-3 sentences) Fingerprint access data can verify the authenticity of vehicle identity and data, and prevent fraud by forging vehicle information or tampering with sensor data. For example, if the fingerprint access data shows that the vehicle's mileage has decreased abnormally, there may be fraud in which the odometer has been tampered with.

Which vehicle service scenarios can the technical solution proposed in this patent be applied to? (2-3 sentences) This technical solution can be applied to various vehicle service scenarios, such as vehicle leasing, Internet of Vehicles services, autonomous driving, vehicle insurance, etc. Through blockchain technology and vehicle sensor data, safer, more efficient and intelligent vehicle services can be achieved.

Answer

Short answer questions

This patent uses vehicle sensor data to generate a unique "fingerprint" value as the basis for vehicle identity verification. The method collects sensor data such as the vehicle's fuel level, mileage, location, etc., and generates fingerprint access data according to a preset algorithm for verifying vehicle identity and authorizing requests.

Fingerprint access data contains granular value data, global warning data, and error flag data. Granular value data is used to quantify the consistency of vehicle data; Global warning data tracks the frequency of suspicious events; Error flag data is set when a serious anomaly is detected to directly reject the request.

Smart contracts define the rules and logic of vehicle service requests, such as the fingerprint access data thresholds required for different request types, conditions for automatic approval or manual approval, etc. Blockchain nodes verify requests and perform corresponding operations according to the provisions of the smart contract.

A machine account is a blockchain account bound to a specific vehicle that can store and manage digital assets. Vehicle service providers can complete payments by accessing the vehicle's machine account without manual intervention.

Streaming settlement can process and settle transactions in real time, improving transaction speed and efficiency, especially when processing micro-transactions. Traditional settlement methods usually require batch processing of transactions, which has problems of delay and inefficiency.

Blockchain network throughput refers to the number of requests that can be processed per unit time. If the number of vehicle service requests exceeds the throughput of the blockchain network, it will cause network congestion, transaction delays, and affect service quality.

This method monitors the throughput of the blockchain network, sorts and buffers vehicle service requests, ensures that the number of requests does not exceed the network load, avoids network congestion and transaction delays, and ensures the stability of the service.

It can be judged by comparing the fuel sensor data and mileage sensor data of the vehicle before and after refueling. If the fuel sensor data of the vehicle increases after refueling, and the mileage sensor data does not change abnormally, it can be judged that the vehicle has refueled.

Fingerprint access data can verify the authenticity of vehicle identity and data, and prevent fraud by forging vehicle information or tampering with sensor data. For example, if the fingerprint access data shows that the VIN code of the vehicle does not match the historical record, there may be a falsification of vehicle identity.

This technical solution can be applied to various vehicle service scenarios, such as vehicle leasing, Internet of Vehicles services, autonomous driving, vehicle insurance, etc. Through blockchain technology and vehicle sensor data, safer, more efficient and intelligent vehicle services can be achieved.
