The product characteristic value corresponding to the product data may be determined by secure hash algorithm 2 (Secure Hash Algorithm, SHA-2), commercial code 3 (Standards Manual 3, sm 3), or the like. In the embodiment of the application, the determination manner of determining the characteristic value of the product can be adjusted according to a specific application scene.
Illustratively, first product information corresponding to product data is received, wherein the product information is transmitted by the same product issuer that transmitted the product data. Then, the product information is input into SM3, and a hash value corresponding to the product information is output, wherein the hash value is the product characteristic value.
In the determining of the product characteristic value corresponding to the product data, the product characteristic value corresponding to the product data may be determined by receiving the product characteristic value corresponding to the product data. Specifically, a product publisher uses product information to generate a product characteristic value, and then the product characteristic value is sent to a product service platform. And the product service platform receives the product characteristic value to determine the product characteristic value corresponding to the product data.
After writing the product data into the target blockchain and synchronizing the product data to multiple blockchains, each enterprise (e.g., product querier) can quickly query the product data.
In one possible implementation, when the product querying party needs to acquire the target product data, the product querying party can query the target product data by inputting a query keyword in the product service platform so as to acquire complete information of the target product data. The complete information of the target product data includes at least the target product data.
When the target product data only includes the target product release data, the complete information of the target product data may also include the target product modification data and the target product revocation data, where the target product modification data and the target product revocation data are displayed as "none" to indicate that the target product data is not modified by the target product release party and is not revoked.
Specifically, the product service platform first receives a query keyword (such as a product feature value) input by a product query party. And then, searching target product data corresponding to the query keyword, and submitting the target product data to a product query party so that the product query party can verify the target product data by utilizing a digital certificate of a target product issuer corresponding to the target product data. And after the verification of the product inquirer is passed, namely when the product service platform receives the passing information indicating the verification of the product inquirer to pass, providing the complete information corresponding to the target product data for the product inquirer.
When the target product data corresponding to the query keyword is searched, firstly, the product identifier (such as the ID of the product, the index number of the product, etc.) corresponding to the query keyword is determined in the target blockchain through the query keyword. And then, determining target product data corresponding to the query keywords and complete information of the target product data in a target database based on the product identification.
The target product data is submitted to the product inquiry party, so that when the product inquiry party verifies the target product data by utilizing the digital certificate of the target product issuer corresponding to the target product data, the product inquiry party firstly acquires the digital certificate of the target product issuer corresponding to the target product data. The digital certificate is obtained in the prior art, and will not be described herein.
It should be noted that, the digital certificate includes the public key of the target product issuer corresponding to the target product data, so that the target product data can be verified based on the public key to obtain the verification result. If the verification result is the first preset value, determining that the verification is passed, and determining that the target product data is sent by the target product publisher. The first preset value may be 1. If the verification result is a second preset value, determining that the verification is not passed, wherein the second preset value can be 0.
When the complete information corresponding to the target product data is provided for the product inquirer, the complete information corresponding to the target product data can be provided for the product inquirer in a display interface mode, so that the product inquirer can more intuitively and rapidly learn the complete information corresponding to the target product data. And the product inquiry party can carry out operations such as transaction with the target product issuing party corresponding to the target product issuing data based on own requirements by providing the complete information corresponding to the target product data for the product inquiry party.
In addition, in the embodiment of the application, the product inquiry party and the target product issuer may be at the same blockchain node, or may not be at the same blockchain node, that is, the product inquiry may be an enterprise added with the product service platform, or may be an enterprise not added with the product service platform. The product inquirer can also be an enterprise in the blockchain corresponding to the blockchain nodes which are added into the complete blockchain and are except for the product service platform.
In summary, when the service method of the product provided by the application is applied to a product service platform, after receiving product data obtained by sorting and digitally signing data corresponding to product information based on a digital certificate from a product issuer, the product data is written into a target blockchain and is synchronized to a plurality of blockchains. According to the method, the digital certificate of the product issuer is utilized, so that the received product data contains the digital certificate signature of the product issuer, modification of the product data by a malicious third party is avoided, authenticity, reliability and credibility of the product data are ensured, denial of the product data by the product issuer is avoided, and the product data has undeniability and traceability.
And the product service platform rapidly synchronizes the product data to a plurality of blockchains through a blockchain technology, so that each enterprise (such as a product inquirer) can learn the product data at the first time, and accordingly related operations (such as transaction operations) are performed, and the product data is high in efficiency and timeliness.
In addition, the product service platform also supports the participation of mass enterprises (such as various product publishers) and the release of mass product data (such as various product release data, product modification data and product revocation data), and has the release capability of mass enterprises and mass product data.
Based on the same inventive concept, the embodiment of the present application provides a service method of a product, where the method is applied to a product publisher, please refer to fig. 2, and the implementation steps of the method include:

Therefore, when the malicious third party modifies the product data, the verification fails when the product data is verified by the public key of the product issuer. Only when the product data is not tampered, the verification can be successful when the public key of the product issuer is used for verification. Therefore, by the method, whether the product data is tampered or not can be determined based on the digital signature contained in the product data, and modification of the product data by a malicious third party is prevented, so that the product data has safety and authenticity; meanwhile, the identity of the product issuer can be confirmed through the digital signature, and the product issuer is prevented from repudiation.
Further, after the product data is obtained, the product data is sent to the product service platform, so that the product service platform writes the product data into the target blockchain and synchronizes the product data to the plurality of blockchains, and therefore the product data can be known by enterprises at the first time. And because the blockchain is the distributed storage that adopts, can prevent that certain node information from damaging the back, lead to the loss of product data, the enterprise economic loss that leads to because of the loss of product data.
The technical scheme of the application is further described below in connection with a specific application process.
Fig. 3 is a schematic diagram of a processing procedure of a service method of a product, in which a product publisher of a product service platform is added first, and a product list is filled in according to each product information of the product. The product inventory includes at least one of a product issue inventory, a product modification inventory, and a product revocation inventory. And then, the product publisher collates the data corresponding to the product list to obtain the product data to be sent. And secondly, the product issuer performs digital signature on the product data to be sent based on the digital certificate of the product issuer to obtain the product data. The product data comprises at least one of product release data corresponding to the product release list, product modification data corresponding to the product modification list and product revocation data corresponding to the product revocation list. Then, the product publisher sends the product data to the product service platform, so that the product service platform performs writing or synchronous operation on the product data in the blockchain.
And after the product data transmitted by the product publisher is received, the product service platform carries out auditing on the product data, stores the product data into a target database after the auditing is passed, and simultaneously determines a product characteristic value corresponding to the product data. The product characteristic value is then written into the target blockchain and synchronized to a plurality of blockchains so that each enterprise (e.g., product inquirer) knows the product data.
The product querier inputs query keywords (e.g., product feature values) at the product service platform.
After receiving the query keyword input by the product query party, the product service platform firstly searches the index number corresponding to the query keyword. And then, searching the complete information of the target product data corresponding to the query key words in the target database through the index number, wherein the complete information comprises the target product data. And then submitting the target product data to a product inquiring party so that the product inquiring party can verify based on the target product data.
After receiving target product data corresponding to the query key words, the product query party firstly acquires a digital certificate of a target product issuer corresponding to the target product data, then analyzes a public key of the digital certificate, and then verifies the target product data by using the public key. And after the verification is passed, receiving the complete information of the target product data provided by the product service platform.
When receiving passing information indicating that the target product inquirer passes verification, the product service platform displays the complete information of the target product data to the product inquirer through a display interface so that the product inquirer can execute corresponding operation based on own requirements.
By the method, the product issuer performs digital signature on the product data to be transmitted by using the digital certificate of the product issuer, so that the obtained product data contains the digital certificate signature of the product issuer, the authenticity, the reliability and the credibility of the product data are ensured, the phenomenon that the product issuer refuses to acknowledge that the product data are issued is avoided, the product data have undeniability and integrity, and the product data are prevented from being modified by a malicious third party. And the product service platform utilizes the blockchain technology to quickly synchronize the product characteristic value of the product data to other blockchains, so that the product data can be known by other enterprises at the first time. Meanwhile, as the product data is stored in a distributed mode, economic losses of enterprises (such as product publishers) caused by information loss corresponding to the product data after information of a certain node is damaged can be avoided. In addition, the product service platform also supports massive enterprise residence and massive product data release, and has the capabilities of massive enterprise and massive product data release, modification and revocation.
