面向自动驾驶全链条测试数据交易的区块链确权方法

A Blockchain Validation Method for Data of Autonomous Vehicles Full-chain Testing

自动驾驶全链条测试过程中产生的海量测试数据,可通过交易释放其潜在的价值。但因测试数据来源多样等原因,导致数据责权不清,造成交易难以安全开展。现提出基于区块链的测试数据确权方法,利用“元数据+云存储”方案,实现测试数据在区块链上的存储与访问,并在综合考虑测试数据生产者、数据平台和数据消费者三方参与的情况下,设计测试数据在区块链系统中实现确权和交易的流程。测试数据的确权和交易过程被记录在区块链上,保障了确权过程和交易过程的公开可审计性和可追溯性,具有公平交易、去中心化等优势。

The vast amounts of autonomous vehicles full-chain testing data can be traded to unlock its potential value.However,due to various test data sources and other reasons,the responsibility and rights of data are unclear,which makes it difficult to carry out the transaction safely.This paper proposes a method to confirm the right of test data based on blockchain,realizing the storage and access of test data on blockchain by using"metadata+cloud storage".Designing the process of realizing the right confirmation and transaction of test data in the blockchain system with comprehensive consideration of the participation of test data producers,data platforms and data consumers.The rights confirmation and transaction process of the test data are recorded on the blockchain,which guarantees the open auditability and traceability of the rights confirmation in transaction process,and has the advantages of fair trading and decentralization.
