Abstract

The embodiment of the invention provides a commodity tracing method and device based on a block chain technology. The invention relates to the technical field of block chains. The commodity tracing method comprises the steps: obtaining commodity packaging and delivery information from a block chain, performing signature processing on the commodity packaging and delivery information through a firstprivate key of a delivery party, and encrypting the commodity packaging and delivery information after signature processing through a second public key of a receiving party; obtaining traceability information generated by a traceability sensor in a packaging box of the commodity from the block chain; decrypting the traceability information and the commodity packaging and delivery information by using the second private key to obtain the commodity packaging and delivery information after signature processing and the traceability information; utilizing the first public key to carry out signature verification on the commodity packaging and delivery information to obtain commodity packaging and delivery information; and verifying the commodity package delivery information and the traceabilityinformation to verify the authenticity of the commodity. According to the technical scheme provided by the embodiment of the invention, the problem that the authenticity of commodity logistics data cannot be guaranteed in the prior art can be solved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of blockchain technology, in particular to a commodity traceability method and device based on blockchain technology. [0003] 【Background technique】 [0004] At present, the problem of counterfeit products at home and abroad is becoming more and more serious, especially in the field of luxury cosmetics, which brings property losses to users.
