Traceable transaction method based on block chain, environment and commodity fingerprints

Abstract

The invention discloses a traceable transaction method based on a block chain, an environment and a commodity fingerprint. The method comprises the following steps: achieving the real and accurate recording of commodity transaction process information based on the block chain through employing an application-verification-recording process, and guaranteeing the normalization of commodity handover through employing the environment fingerprint and the physical characteristics of a short-distance handheld device. And confirming the consistency of the recorded commodities in the commodity transaction process by using the commodity fingerprints. According to the method, the fraud problem existing in online entity commodity transaction can be completely eradicated and detected from the source, so that the authenticity and reliability of whole transaction process information are ensured, recorded information is ensured to be accepted by participants, mutual trust among the transaction participants is established, fraud prevention and long-term traceability of the whole transaction process are realized, and the transaction efficiency is improved. Therefore, the interests of all parties participating in the transaction can be effectively protected.

Description

technical field [0001] The invention belongs to the field of data traceability, and specifically relates to a traceable transaction method based on blockchain, environment and commodity fingerprints. Background technique [0002] Blockchain technology has been widely used in various scenarios and fields that require authentic and credible information because of its features such as no need for a trusted center, non-tampering, and traceability. With the vigorous development of e-commerce, more and more people accept online transactions, especially in the current situation of the raging new crown pneumonia epidemic, long-distance, especially cross-border offline transactions have become difficult, so more and more More and more commodities are also beginning to explore the possibility of online transactions. The current commodity online transaction platform provides an environment for commodity online transactions, but there are relatively large loopholes in tracing the entir...

AI Technical Summary

Problems solved by technology

[0004] 1. In the trading platform, most of the transaction-related information is recorded in centralized storage media. These storage media do not have credibility, and cannot guarantee that the information is always true and will not be modified. With the growth of transaction volume, it is necessary to continuously expand the storage The capacity of the medium requires high maintenance costs. At the same time, it needs to bear the risk of data loss caused by the failure of the storage medium, and the long-term traceability of relevant data cannot be guaranteed.

[0005] 2. Most of the current transaction information is uploaded and maintained by commodity providers and commodity transporters, and it is difficult to effectively protect the rights and interests of commodity buyers, especially when commodity providers and commodity transporters collude with each other, so commodity providers and commodity Trust among buyers cannot be effectively built

[0006] 3. When the transaction platform involves commodities with high transportation costs and high prices, the disputes arising after the commodities arrive at the buyers are difficult to deal with and the settlement costs are high

[0007] 4. In the current transaction process, there are no constraints on the transfer of goods between the two parties, and its compliance cannot be supervised and verified. Disputes arising from this in the later period cannot be effectively pursued

[0008] 5. Most of the existing commodity traceability methods and models are related to supply chain-related industries, and their products come from a complete supply chain rather than commodity transaction scenarios, and these methods only focus on information records. There is no method of verifying and supervising the authenticity of the information, nor does it pay attention to the matching of goods and information

In these methods, most of the physical labels are used as the unique identification of the goods. This type of identification is not suitable for long-distance and multi-stage transportation. During the transportation, there are problems such as easy to fall off, easy to be damaged, and destroy the original usability of the goods.
