Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings.
As shown in fig. 1 to 4, a traceability system for commodity holders on a block chain includes the following steps:
step S1: establishing an enterprise-level alliance chain, and supporting a manufacturer and a user to establish own child nodes or a child node network to be added into a main node block chain network;
step S2: a user generates a public and private key pair through an asymmetric encryption technology;
and step S3: the user imports own identity, and the public key is uploaded to the server in the process and then stored in the block chain network;
and step S4: a manufacturer uses a Web management end to mark the commodity generation number, and stores the commodity number and the commodity holder into a block chain;
step S5: the commodity circulation requires the change of the commodity holder, and only the commodity holder can circulate the commodity.
According to the method and the device, the user information acquisition and verification are divided by using the asymmetric encryption technology in the block chain, and the operator can be judged to be the user without acquiring the user information, so that the user privacy problem can be solved, a centralized credit mechanism is not needed for managing and identifying the identity, and the decentralization is possible.
Through the alliance chain technology in the block chain, each manufacturer and each user can establish a node of the manufacturer and each user to join the block chain network, and each manufacturer and each user can master data of the manufacturer and each user, so that the ownership of the data is guaranteed. And by using the channel technology, the business privacy data of the user is protected from being accessed by irrelevant nodes, and the isolation and privacy of the data are also guaranteed. The data is not only stored in the centralized system, but also has the control right and the use right of the data, and the semi-decentralized or full decentralized system is realized. And the producer can inquire and count the destination of the commodity through the system, so that the management efficiency of the supply and sale chain is improved qualitatively.
Further, in the step S1, a Hyperridge-Fabric is used for building an enterprise cascade alliance block link layer network; and supporting the user to set up own child nodes or add the child node network into the main node block chain network. Therefore, the user can master own data after constructing the child node or the child node network.
Further, in the step S2, the process of generating the public and private key pair is completed locally without going through the server, so that it is ensured that the private key of the user is not revealed; the public key is the identity of the public key, and the private key is used for verifying the identity. The system uses the public key as the product holder identification.
Further, in step S4, the manufacturer prints the two-dimensional code on the commodity, and one object is one code, and the two-dimensional code is stored with the access link of the h5 page for accessing the commodity, and the tracing information of the holder of the commodity is displayed in the h5 page, including the quantity of the commodity currently held by the commodity holder and the circulation quantity of the commodity circulated by the commodity holder to other commodity holders, so that the manufacturer can clearly know the commodity sales condition of the manufacturer, and the quality of the management of the supply chain can be improved.
Further, in the step S5, when the commodity is circulated, the commodity state has two states of release and non-release, when the current holder of the commodity verifies the identity with the private key to execute the release operation, and the commodity state is modified to the release state; and the receiver executes receiving operation, modifies the commodity holder into a receiver as a new commodity holder, modifies the commodity state into a non-release state and finishes the commodity circulation. By analogy, the new product holder also circulates the product in the same manner. Thereby, the history record of the commodity can be inquired according to the commodity number.
Furthermore, after the circulation of the commodities is completed, the circulation data are statistically displayed to the Web management end, and the quantity of the commodities currently held by the commodity holder and the circulation quantity of the commodities, which are circulated to other commodity holders by the commodity holder, are displayed.
The above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
