Target object tracing method and device

Abstract

The invention provides a target object tracing method and device. The target object tracing method comprises the steps of acquiring first digital information of a target object, generating identification information of the target object, generating a block chain of the target object according to the identification information of the target object, binding each piece of digital information of the target object in different stages, such as first digital information in a production stage, second digital information in a transportation stage and third digital information in a transaction stage with the block chain, and further being capable of providing each piece of digital information related with the block chain by taking the identification information of the block chain as a query basis, so that each piece of digital information of the target object is acquired through the identification information of the block chain, and thus tracking for production conditions and transaction conditions of the target object is realized according to each piece of digital information of the target object. In addition, when the target object tracing method and device are applied to a transaction scene, information such as the source and quality of the target object can be acquired through each piece of digital information, and both sides of the transaction are enabled to master the same information such as the source and quality of the target object.

Description

technical field [0001] The invention belongs to the technical field of information tracking, and more specifically, relates to a method and device for tracing the source of a target object. Background technique [0002] With the rapid development of e-commerce, commodity trading through e-commerce has become an important social consumption pattern, and factors such as information infrastructure, logistics distribution and electronic payment that once restricted the popularization and application of e-commerce have also been greatly improved. But with the rapid development of e-commerce, there are still many problems to be solved. [0003] For example, some unscrupulous manufacturers use OEM (Original Equipment Manufacturer, Original Equipment Manufacturer) and other methods to entrust small factories to produce on their behalf, resulting in serious discounts on product quality and brand spillover benefits, which in turn damages the interests of buyers and pollutes the e-comm...

AI Technical Summary

Problems solved by technology

[0003] For example, some unscrupulous manufacturers use OEM (Original Equipment Manufacturer, original factory commissioned manufacturing) to entrust small factories to produce on their behalf, resulting in serious discounts in product quality and brand spillover benefits, which in turn damage the interests of buyers and pollute the e-commerce environment. , and even become a bottleneck affecting the development of e-commerce to a certain extent

[0004] To this end, commodity transactions can be monitored by publishing information on electronic platforms related to e-commerce (such as commodity information and credit endorsement, etc.), rewards and punishments on electronic platforms, and supervision by national regulatory authorities. The two sides of the transaction have a serious asymmetry of information on the source and quality of the goods, especially for the buyer of the transaction. When the seller adopts the OEM method and entrusts a small factory to produce on its behalf, the buyer has no way of knowing this situation. Therefore, there is a serious asymmetry in the information that both parties to the transaction have about the source and quality of the commodity.
