Short answer questions

A car registration certificate is an official document that proves the identity of a vehicle, similar to a motor vehicle registration certificate. It usually contains technical specifications, ownership history, and other relevant information about the vehicle.

This patent document aims to solve several problems associated with traditional vehicle registration certificates, such as forgery, theft, and information opacity. It proposes a method of using blockchain technology to create a secure and tamper-proof vehicle history record.

Blockchain technology records vehicle history by creating a decentralized and tamper-proof ledger. Every time a change or addition is made to vehicle data, a new “block” is added to the blockchain, creating a permanent and verifiable record.

A “program module” is a standalone program stored in the blockchain that manages operations and data access rights associated with a specific vehicle. It acts as a smart contract that defines how different parties can interact with vehicle data.

Automakers can use their private key to create a new entry in the blockchain containing initial vehicle data, such as VIN, model, date of manufacture, etc. This initializes the vehicle’s identity on the blockchain.

Vehicle data can be transferred from vehicle sensors to the blockchain in a variety of ways, such as through the vehicle’s built-in communication system or through an external device connection. Every time the data is updated, it is signed using the vehicle’s private key to ensure authenticity.

Repair shops can use their private key to add information about vehicle repair and maintenance records to the blockchain. This may include services performed, parts used, and relevant dates.

Vehicle owners will receive a vehicle registration certificate containing a machine-readable code. Third parties can use the code to access vehicle data stored in the blockchain and verify the authenticity of the data using the public key associated with the vehicle.

Vehicle data stored in the blockchain can be verified using cryptographic signatures. A third party can verify the authenticity of the signature using the vehicle's public key, thus ensuring the integrity and authenticity of the data.

Due to the tamper-proof nature of blockchain, past records cannot be altered. Any attempt to change the odometer reading will conflict with the previous data recorded in the blockchain, making fraud easy to detect.

Glossary

Term Definitions Blockchain A decentralized, tamper-proof, distributed database used to record transactions and track assets. Program Modules Independent programs stored on a blockchain that act as smart contracts and manage specific processes or data. Public Key Cryptography A cryptographic system that uses a pair of keys (public and private) to encrypt and decrypt data. Private Key A cryptographic key that is kept secret and known only to the owner and is used to sign data and authorize transactions. Public Key A cryptographic key that is paired with a private key and is used to verify a signature made with the corresponding private key. Machine Readable Code A code that can be read and interpreted by a machine, such as a barcode or QR code. Tamper Proof Cannot be changed or modified without being detected. Vehicle Data Any information related to a vehicle, such as odometer readings, maintenance records, ownership history, etc. Auto Manufacturer A company or organization that designs, manufactures, and sells automobiles. Repair Shop A facility that provides vehicle repair and maintenance services.
