[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] A method for associating an e-commerce product with a product quality certificate comprises the following steps:

[0030] Step S1: constructing an e-commerce product information database and a blockchain, wherein the e-commerce product information database includes product codes and electronic product quality certificates of a number of e-commerce products, and each e-commerce product code corresponds to an electronic product quality certificate;

[0031] Step S2: Obtain the product code of the e-commerce product to be associated;

[0032] Step S3: According to the product code of the e-commerce product to be associated, obtain the corresponding electronic product quality certificate from the e-commerce product information database;

[0033] Step S4: Calculate the hash value of the content of the electronic product quality certificate of the e-commerce product to be associated to obtain a first hash value;

[0034] Step S5: Combining the product code of the e-commerce product to be associated, the content of the electronic product quality certificate of the e-commerce product to be associated, and the first hash value into a json string;

[0035] Step S6: Perform hash processing on the json string to obtain a second hash value;

[0036] Step S7: Store the second hash value in the blockchain to complete the association between the e-commerce product to be associated and its corresponding electronic product quality certificate.

[0037] A method of associating e-commerce products with product quality certificates in this solution, such as Figure 1As shown, the first step is to construct an e-commerce commodity information database and a blockchain, wherein the e-commerce commodity information database includes the product codes and electronic commodity quality certificates of several e-commerce commodities, and each e-commerce commodity product code corresponds to an electronic commodity quality certificate. In this embodiment, by constructing an e-commerce commodity information database, it is beneficial to better store and manage the information data of e-commerce commodities. Each e-commerce commodity has a unique product code and an electronic commodity quality certificate. By constructing a blockchain, the information on the blockchain cannot be tampered with at will. The second step is to obtain the product code of the e-commerce commodity to be associated. In this embodiment, by obtaining the product code of the e-commerce commodity to be associated, it is beneficial to the subsequent association of the e-commerce commodity with the electronic commodity quality certificate. The third step is to obtain the corresponding electronic commodity quality certificate from the e-commerce commodity information database according to the product code of the e-commerce commodity to be associated. In this embodiment, since each e-commerce commodity product code corresponds to an electronic commodity quality certificate, the corresponding electronic commodity quality certificate to be associated can be retrieved from the e-commerce commodity information database according to the product code of the e-commerce commodity to be associated. The fourth step is to calculate the hash value of the content of the electronic product quality certificate of the e-commerce product to be associated, and obtain the first hash value. In this embodiment, by calculating the hash value of the content of the electronic product quality certificate of the e-commerce product, it is helpful to verify the integrity and authenticity of the electronic product quality certificate of the e-commerce product. Further explanation, the SHA-256 hash algorithm is used when calculating the hash value to ensure the security and uniqueness of the first hash value. The fifth step is to combine the product code of the e-commerce product to be associated, the content of the electronic product quality certificate of the e-commerce product to be associated, and the first hash value into a json string. In this embodiment, since the json format has good readability and easy parsing characteristics, the product code of the e-commerce product to be associated, the content of the electronic product quality certificate of the e-commerce product to be associated, and the first hash value are combined into a json string, which is conducive to subsequent processing. The sixth step is to hash the json string to obtain a second hash value. In this embodiment, by hashing the json string containing key information, a unique identifier, namely the second hash value, can be generated, which is conducive to the subsequent storage of this unique identifier in the blockchain. The seventh step is to store the second hash value in the blockchain to complete the association between the e-commerce product to be associated and its corresponding electronic product quality certificate. In this embodiment, by storing the second hash value in the blockchain, the data on the blockchain can be ensured to be tamper-proof and traceable. After completing the association between the e-commerce product to be associated and its corresponding electronic product quality certificate, the supplier will print the associated product code on the packaging of each e-commerce product after completing the production of a batch of e-commerce products. The product code is a barcode or WeChat applet code. When the e-commerce product is shipped out, the corresponding electronic product quality certificate can be viewed by scanning the product code on the e-commerce product packaging.

[0038] In this solution, an e-commerce product information database and blockchain are constructed, and the corresponding relationship between the product code and the electronic quality certificate is used, combined with hash processing technology, to achieve an effective association between e-commerce products and their quality certificates. In this solution, when calculating the hash value, the hash value of the content of the electronic product quality certificate of the e-commerce product is first calculated, and then this hash value is combined with the product code of the e-commerce product and the content of the electronic product quality certificate of the e-commerce product to form a json string, and the json string is hashed to obtain the final hash value. This method of calculating hash values ​​increases the level and complexity of the data structure, so that any modification to the product quality certificate can be detected through changes in the hash value, making it easy to detect tampering.

[0039] Preferably, in step S7, after the association between the e-commerce product to be associated and its corresponding electronic product quality certificate is completed, the following steps are also included: by identifying the product code of the associated e-commerce product, the corresponding electronic product quality certificate is obtained and displayed visually. In this embodiment, after the association between the e-commerce product to be associated and its corresponding electronic product quality certificate is completed, the supplier can view the electronic product quality certificate of the e-commerce product on the mobile phone or computer by identifying the associated product code on the e-commerce product packaging, so that the supplier can intuitively understand the quality of the e-commerce product.

[0040] Preferably, the following steps are further included: regularly updating the product codes and electronic product quality certificates of the e-commerce products in the e-commerce product information database. In this embodiment, regularly updating the product codes and electronic product quality certificates of the e-commerce products in the e-commerce product information database is conducive to ensuring the accuracy and timeliness of the information in the e-commerce product information database.
