Technical Field
The invention relates to the technical field of block chains, in particular to the fields of block chain intelligent contract application and product traceability.
Background
For the identification and tracing problems of articles, particularly products in production and circulation, the traditional method records the articles based on a centralized database, and the articles are identified by bar codes and two-dimensional codes and bound with records in the database. The method for identifying and tracing the article has the following problems: (1) the data is stored in a centralized database, and a system manager can easily modify the data, so that the related data of the articles lack of public confidence; (2) a plurality of information islands are finally formed by the centralized databases which are respectively administrative, so that the sharing and the whole-course tracing of the article information in the industrial chain are difficult to realize; (3) the centralized database and the service platform are easy to be attacked by the network when running in the internet, have certain potential safety hazards and are difficult to provide highly available sustainable services.
Disclosure of Invention
In view of the above, the invention designs a decentralized article anti-counterfeiting mark and tracing method and system, by deploying an intelligent contract for recording and controlling the article anti-counterfeiting mark, tracing information and management information on a block chain, storing an article description information template and article identification data in a distributed file system, and storing an association relation between an article anti-counterfeiting mark code and a description information address stored in the distributed file system in the intelligent contract, the storage and the whole-course tracing of the article anti-counterfeiting mark data and the tracing data can be realized under a completely decentralized operating environment, so that the problems of the public credibility, information isolated island, safe and reliable operation and the like of article data storage are solved. In order to achieve the purpose, the technical scheme of the invention is realized as follows:

secondly, defining object identification description information templates in different states aiming at the change process of managed objects in production and circulation, and defining the object identification description information templates as different types of identifications;
then, in a certain state in the production and circulation process of the article, when an independent article is newly generated, a new article identifier corresponding to the type of the article identifier in the state is created, and the identifier is recorded in a two-dimensional array in an intelligent contract, such as labels [ labelTypeIndex ] [ label ] ═ 1;
then, according to the related acquired data and the information description template of the article, filling description data of the article identifier, storing the described data in a distributed file system, and recording a storage address of the identifier description information in a traceable storage two-dimensional array (with the article state type and the identification number as subscripts) in an intelligent contract, such as SourceLabel [ activityIndex ] [ label ] ═ dataHash;
thirdly, the combination of the state type and the identification of the article is used as the unique identification code of the article to generate a two-dimensional code, and the generated label is printed or printed to be bound with the article entity one by one;
finally, the user scans the two-dimensional code of the article through a special App or WeChat or other tools, the identification and record information of the article can be inquired from the block chain network, the related description information of the article is obtained from the distributed file system, and the layer-by-layer traceability inquiry of the article is realized according to the correlation of the description information to the description information of the article at the upper level.
As shown in fig. 1, the generation rule of the anti-counterfeit code of the article identifier of the article anti-counterfeit identifier and tracing method is as follows: the article identification anti-counterfeiting code is hash (article identification + random password), wherein the random password in the anti-counterfeiting code is automatically and randomly generated when the article identification is created and is printed on the article label; meanwhile, a mark variable for judging whether the mark is subjected to anti-counterfeiting verification is designed in the intelligent contract.
As shown in fig. 2, the anti-counterfeit protection process of the article anti-counterfeit label and tracing method includes the following steps:
firstly, an operator creates an article identifier, a system automatically generates a random code, and generates an article identifier anti-counterfeiting code together with the article identifier, and the article identifier anti-counterfeiting code is recorded in an article identifier array;
secondly, printing the random code and the article identification on the article label, wherein the random code is covered by a scratch-off coating;
thirdly, when the user performs the anti-counterfeiting verification of the article identifier, scraping the random code coating, and uploading the intelligent contract verification by scanning the article identifier and the random code;
fourthly, the intelligent contract checks whether the anti-counterfeiting code recorded by the article identification is as follows:
the anti-counterfeiting code is hash (article identification + random code), and whether anti-counterfeiting verification is carried out is checked;
and fifthly, if the anti-counterfeiting codes do not accord with each other or the anti-counterfeiting verification is carried out, returning a message that the anti-counterfeiting verification of the article fails to pass to the user, otherwise, setting the anti-counterfeiting verification record as true, and returning a message that the anti-counterfeiting verification passes.
As shown in fig. 3, the description of the item identifier and tracing method for different categories of identifiers includes the following description:
(1) identifying a name;
(2) identifying a length;
(3) identifying a maximum allowed number;

(2) identifying a type;
(3) whether to create a new identity;
(4) whether there are multiple sources of items;
(5) the distributed file system storage addresses of the template are described.
As shown in fig. 1, the present method for identifying and tracing an item can authorize a specific administrator account to modify the value for the maximum allowable quantity of the item identifier.
As shown in fig. 4, the article identification and traceability system includes the following components:
(1) blockchain networks (alliance or public chains), distributed file systems (IPFS or ethernet Swarm);
(2) storing an intelligent contract of the article identification, the incidence relation and the management information;
