语义网技术与区块链技术的交集在农产品质量安全追溯领域的应用

Applying the Integrated Technologies of the Semantic Web and the Blockchain to the Agro-products Tracing System

农产品的质量追溯信息平台覆盖了农产品供应链的各环节,其使用效率和效果受到两方面因素的影响:(1)数据采集形式对追溯履历(pedi gr ee)获取的及时性、准确性和完备性的影响;(2)数据登记和服务形式对数据安全与查询服务体验的影响。归结起来是农产品质量安全数据的关联价值与可靠性的范畴。文章讨论了在供应链各环节数据化程度基本满足的前提和半开放的应用场景下,通过语义网技术与区块链技术结合,建立起分布式、有信用保障的农产品质量安全追溯应用体验的可能性,并提出一个概念验证系统的设计。

The efficiency and the effectiveness of a tracing and tracking information system for agro-products result from following factors:(1) the influences from the data collection methods on the timeliness, the precision and completeness of the tracing pedigree;(2) the influences of data registration and service form on the data security and the data access service experiences. They can be categorized as the scopes of linking value and the reliability of the agro-products tracing system data. In this paper, we proposed that in case of the member organizations of a tracing system can guarantee the local digitization and they form a kind of half-open application scenario, and establish a distributed and trusty experimental agro-products tracing system can be developed by applying the integrated technologies of the semantic web and blockchain.
