Problems solved by technology

However, consumers cannot clearly and intuitively feel the content of chemical substances in milk powder
In addition, since most merchants do not have suitable channels to provide consumers with test certificates from third-party testing agencies, they cannot provide authoritative guarantees for the safety of maternal and child products; The test certificate of the third-party testing agency, this way of proof also greatly increases the production cost of maternal and child products, and also cannot guarantee the authenticity of the test certificate provided by the merchant

Embodiment 1

[0040] It is based on the above two characteristics of the blockchain that it can give full play to its advantages when used in the field of anti-counterfeiting and traceability. The present invention provides a method for traceability of maternal and infant products based on blockchain technology on the basis of blockchain technology. figure 1 shown, including the following steps:

[0041] S11. Package the product data of maternal and infant products and the detection data provided by the third party into sub-blocks, and upload them to the blockchain platform.

[0042] S12. Allocate a node corresponding to the blockchain platform for each maternity and baby product manufacturer.

[0043] The product data in the above step S11 is provided by the manufacturer of maternity and baby products. Therefore, after the product data is entered into the blockchain platform, a corresponding node needs to be assigned to each manufacturer of maternity and baby products. Specifically, node...

Embodiment 2

[0066] In this example, for the sake of easy understanding, the specific example of milk powder will be selected as an implementation of maternal and infant products to illustrate the traceability method. Specifically, refer to image 3 shown, including the following steps:

[0067] S31. Package the product data of the milk powder and the detection data provided by the third party into sub-blocks.

[0068] S32. Burn the private key for the sub-block.

[0069] Among them, the private key includes an initial private key and a mobile private key. The initial private key encrypts the initial product data and initial detection data, and the mobile private key encrypts the product data and detection data during the flow of milk powder.

[0070] S33. Assign each milk powder manufacturer a node corresponding to the blockchain platform.

[0071] S34. Deploy the preset smart contracts in the blockchain platform to all nodes in the blockchain platform.

[0072] S35. Record a public ke...

Abstract

The invention discloses a maternal and infant product tracing method based on a block chain. The method comprises the steps: packaging product data of maternal and infant products and detection data provided by a third-party main body into sub-blocks, and uploading the sub-blocks to a block chain platform; allocating a node corresponding to the block chain platform to each mother and baby productmanufacturer; deploying a preset intelligent contract in the block chain platform to all nodes in the block chain platform; and querying the unique identifier of the digital object corresponding to the maternal and infant products to obtain the detection data corresponding to the product data. The detection data of the third-party main body has relatively high authority and can be accepted by mostnodes so that the safety of consumers to the maternal and infant products products is improved. The chained data has the characteristic of being free of tampering so that the integrity of maternal and infant product suppliers and manufacturers is improved to a certain extent and the brand influence of the maternal and infant product suppliers and manufacturers is improved.

Description

technical field [0001] This application relates to the technical field of traceability, and in particular to a blockchain-based traceability method, device and storage medium for maternal and infant products. Background technique [0002] In modern society, people pay more and more attention to safety issues. Especially in the field of maternal and infant products, more attention has been paid to the safety of various maternal and infant products. [0003] In real life, although consumers can learn about some of the ingredients through the outer packaging of maternal and infant products (such as milk powder). However, consumers cannot clearly and intuitively feel the content of chemical substances in milk powder. In addition, since most merchants do not have suitable channels to provide consumers with test certificates from third-party testing agencies, they cannot provide authoritative guarantees for the safety of maternal and child products; The test certificate of the ...
