AI Technical Summary

Technical Problem

Traditional cross-border e-commerce traceability methods rely on centralized data storage, which is easily tampered with or forged. They cannot monitor the status of goods in real time, making it difficult to guarantee the authenticity of goods and the transparency of the supply chain, and they also lack data privacy protection.

Method used

Using blockchain technology, unique traceability codes and anti-counterfeiting hash values ​​are generated for cross-border e-commerce products. Digital signatures and consensus mechanisms ensure that the data is tamper-proof. Anomaly detection algorithms are used to monitor logistics nodes in real time. Zero-knowledge proofs are used to achieve efficient privacy verification and display the traceability path.

Benefits of technology

It enables full-process credible traceability of cross-border e-commerce goods, ensuring product authenticity and supply chain transparency. The traceability path is displayed through a visual interface, providing transparent and credible product information and supply chain monitoring.

Abstract

The invention relates to the technical field of cross-border logistics, and discloses a cross-border e-commerce commodity traceability method and system based on a block chain, and the method comprises the following steps: generating a unique traceability code for each cross-border e-commerce commodity, extracting an original information field of the cross-border e-commerce commodity, and calculating an anti-counterfeiting hash value; performing structured packaging on the original information field and the anti-counterfeiting hash value according to a preset template, confirming a transaction through a consensus mechanism, writing the transaction into a block chain, and generating a block hash value; operation information of all logistics nodes is collected, abnormity is recognized through an abnormity detection algorithm, and data fingerprints obtained after abnormity recognition are encrypted and stored; the encrypted and signed operation information is submitted to a block chain network, and a block chain node verifies the validity of a digital signature through a public key of a producer and verifies the legality through a consensus mechanism; and proving an aggregation verification result by using zero knowledge. According to the invention, a complete traceability path is displayed, and full-chain transparent management from production to consumption is realized.
