And S15, inquiring the product information of the feminine hygiene product through the unique identifier of the digital object.
It should be noted that the solution provided by the present disclosure is implemented based on a blockchain platform, a blockchain network, or a blockchain system, and thus the "blockchain" in this embodiment may refer to any one of the blockchain platform, the blockchain network, or the blockchain system, which is not limited in this embodiment.
In addition, when the blockchain is constructed, the blockchain can be constructed by a blockchain framework, for example. The common mainstream block chain framework includes a bitcoin framework, an etherhouse framework, a Fabric framework, an Onchain DNA framework (Onchain distributed Networks Architecture), a Corda framework, and the like. Different blockchain architectures have different characteristics, for example, bitcoin architectures have characteristics of being able to sell money without a central authority, being able to pay without an intermediary authority, maintaining user anonymity, being unable to revoke transactions, etc.; the Ethengfang framework has the characteristics of complete contract language of pictures, built-in persistent state storage and the like; the Fabric architecture has the characteristics of modular design, replaceable components and the like. Based on the different features of the different blockchain architectures, a blockchain platform that better meets the user requirements can be constructed, and based on this, the blockchain according to the embodiment of the present invention can be constructed according to any kind of blockchain framework, which is not limited in the embodiment of the present invention.
For ease of understanding, the term "feminine hygiene article" as used in this disclosure will be briefly explained below by way of a simple classification and exemplification of feminine hygiene articles, specifically including: daily chemical articles (such as hand sanitizer, laundry detergent and the like), sanitary articles for women during menstrual period (such as sanitary napkins, panty liners, sanitary tampons and the like), sanitary articles for excrement such as diapers and the like (such as diapers and the like), urine-proof pads, skins, mucous membrane sanitary articles (such as wet tissues, wet sanitary napkins and the like), contact lens care articles (such as contact lens care solutions, contact lens preservation solutions, contact lens detergents and the like), gynecological sanitary articles (such as lady anti-bacteria/bacteriostasis lotions, vaginal lotions and the like), other disposable sanitary articles (such as paper towels, sanitary napkins, cosmetic cotton/paper/towels, hands/finger cots, masks, paper drinking utensils, condoms and the like), and the specific types of the feminine sanitary articles are not limited by the embodiment of the invention.
In step S11, the execution body of each stage of the feminine hygiene product distribution process may include at least one of the following: raw material providers, producers, carriers, distributors, agents, users, third party testing facilities, and the like. Accordingly, the present embodiment may deploy at least one of the phase execution bodies as a node in a blockchain, where the node can acquire associated data in the circulation process of the feminine hygiene product. In particular, the associated data may be collected, for example, by a corresponding data collection device, such as a mobile phone, a PDA (personal digital Assistant), a scanner, a sensor, etc.
In addition, those skilled in the art should understand that the number of the data acquisition devices included in each node in the block chain in this embodiment may be one or more, and the number and specific type of the data acquisition devices are not limited in this embodiment.
As a preferred implementation manner of the embodiment of the present invention, before uploading the associated data to the block chain for storage, for example, a trusted timestamp may be added to the associated data. The trusted timestamp is an electronic certificate which is issued by an authoritative trusted timestamp service center, can prove that a data message (electronic file) is existed, complete and verifiable at a time point and has legal effectiveness, and is mainly used for preventing the electronic file from being tampered and repudiated afterwards and determining the accurate time generated by the electronic file.
Specifically, referring to fig. 2, adding the trusted timestamp to the associated data includes the following steps:
and S21, extracting the hash value in the associated data and sending the hash value to the timestamp server.
S22, the timestamp server digitally signs the hash value to generate a trusted timestamp, and binds the trusted timestamp to the associated data.
The setting of the trusted timestamp can provide more authoritative time evidence for the associated data, so that the associated data uploaded to the block chain is further prevented from being tampered by others. In addition, the setting of credible time stamp can convenience of customers to a certain extent trace the source to the feminine hygiene article.
In the step S12, when uploading the related data to the block chain for temporary storage, for example, the related data may be encrypted, and the encrypted related data may be uploaded to the block chain for storage. Common encryption processing methods include symmetric encryption and asymmetric encryption, and in order to sufficiently ensure the security of data. Preferably, the present embodiment performs encryption processing on the associated data in an asymmetric encryption manner. Specifically, the generated public key may be distributed to all nodes in the block chain, and the generated private key is sent to the user node, and only the user that obtains the private key may query the associated data, and the specific manner of encryption is not limited in this embodiment.
As a preferred implementation manner of the embodiment of the present invention, the intelligent contract in step S14 is actually an automatic protocol that needs to be manually executed to complete the task, and includes a set of preset rules. In the data processing or transaction process, if a certain operation or a certain numerical value and the like accord with a preset rule in the intelligent contract, the block chain can automatically execute a specific protocol in the intelligent contract.
In some embodiments of the present application, the user is a user of the product, and is often the party with the longest time for accompanying the product, and is the actual witness of the product quality, and therefore, there is a right of way to the quality comparison of the product. At present, users can only reflect quality problems to direct sellers of products, a general and relatively fair platform is lacked to collect feedback data of consumers, and the setting of intelligent contracts in a block chain can meet the requirement.
When the associated data inquired by the user is not matched with the product information, considering the credibility of the associated data, the product information is considered to have errors or the product corresponding to the product information is considered to be a fake and fake product, and the like, and through the setting of the intelligent contract, the product information can be broadcasted to all nodes in the block chain to help manufacturers, brands and the like of the products to find out problematic products, so that the manufacturers, the brands and the like can make timely remedial measures.
The user may actively submit feedback data for the product by scanning the digital object unique identifier, the feedback data information including, for example: the method comprises the steps of commodity unpacking process image recording, commodity evaluation and improvement suggestions, commodity object pictures, purchasing channels, purchasing time, purchasing prices, own cities, user identity information, application to qualification presentation of intermediate link parties and the like. The user may also interact with other parties by scanning the unique identifier of the digital object, such as requesting a warranty, requesting a price guarantee, quality issue complaints, and the like.
In addition, the specific form of the smart contract in the above step S14 is only an exemplary illustration and does not constitute a specific limitation of the present disclosure, and other forms of the smart contract may also be configured as follows: when the associated data inquired by the user is not matched with the product information, a feedback channel is provided for the user so as to feed the product information back to a third-party supervision mechanism, an insurance company, a manufacturer, a brand merchant or a seller and the like; or may be configured to: when the associated data inquired by the user is not matched with the product information, a 'one key report' button of a product information page can be directly clicked to inform a third party supervision mechanism, an insurance company, a manufacturer, a brand manufacturer or a seller to process problem products, and the embodiment of the invention does not limit the specific configuration mode of the intelligent contract.
In one embodiment, generating a unique identifier for a digital object from stored association data includes the following two cases:
first, a digital object unique identifier corresponding to each phase is generated based on the stored association data. In other words, each phase corresponds to a unique identifier of the digital object. Second, a plurality of digital object unique identifiers corresponding to each stage are generated based on the stored association data. In other words, each stage corresponds to a plurality of digital object unique identifiers, and specifically, each stage may correspond to 3 or 5 digital object unique identifiers according to the number of terminal devices, for example. The embodiment of the present invention does not limit the specific number of types of unique identifiers of digital objects.
The digital object unique identifier may include, for example, at least one of the following: two-dimensional codes, three-dimensional codes, bar codes, and the like. The two-dimensional code or bar code corresponds to product information for the feminine hygiene product. A user can quickly acquire relevant data about the product by scanning a two-dimensional code or a bar code on the package of the feminine hygiene product through a mobile terminal such as a mobile phone.
In one embodiment, the associated data may be data used directly during the manufacturing process or other data that can indirectly direct the manufacturing process to proceed or to improve subsequent manufacturing processes. The associated data for the feminine hygiene product can include, for example, at least one of: manufacturer qualification, standard statement, production process, product certification, production flow data, logistics data, purchase record, detection data and the like. In addition to the enterprise itself, other parties involved in the production of the product (e.g., raw material suppliers, foundry manufacturers, third-party integrators, etc.) may also provide production data of the product to the blockchain under the authorization of the enterprise. For ease of description, the enterprise itself and these other parties are collectively referred to as the producer.
Enterprise qualifications include, for example, International Organization for standardization (ISO) membership, license plates for business operations issued by government departments, International Telecommunications Union (ITU) membership, and the like.
Standard statements include, for example, national standards, industry standards, draft standards, etc. to which the declared product conforms.
The production process comprises, for example, the steps of describing the origin and vein of the product, the processing links and equipment to be passed from the raw material to the finished product, and the symbols indicating the key control points of each link, even the specific process parameters of the product. The production process may be predetermined before production, and may be different from the actual production process.
The manufacturing process is preferably a relatively broad and practical process and may generally comprise at least most of the actual process stages from the time the product is in a raw material state until the time the product is introduced and used by the consumer. Such as which production lines are actually experienced, who the responsible person is, which warehouse manager's access operations are attended, which dealers are attended, etc. The production process data may, for example, include data of at least one of the following production process stages: the production process comprises an creative stage, a design stage, a research and development stage, a manufacturing stage, a marketing stage, a warehousing stage, a distribution stage and a delivery stage. The member information, generation information and production information (such as drawing, code, document and mould) information of the stages can be used as the production flow data. The production flow data can be submitted to the block chain by the corresponding stage of the manager, or the production flow data can be submitted through a uniform channel after the enterprise integrates the production flow data inside the system, and other production data can be processed similarly. The production data can be submitted by scanning the corresponding two-dimensional code or bar code through a scanning device such as a smart phone, a PDA, a scanning gun, a point of sale (POS) machine, and the like. The associated data may also include more types of data, such as audit data reflecting whether the product is sold in different areas or not, competitive product data on the market, imitation data on the market, and the like.
In some embodiments of the application, after the block chain collects data of each party of the platform, the data may be matched and cleaned based on technologies such as big data, artificial intelligence, cloud computing and the like to obtain quality data of a product, and the quality data may be managed according to the unique identifier of the digital object, such as data association, query response, data update and the like. The block chain is used as an intermediate medium, so that data can be shared among manufacturers, the third-party main body and consumers, the transparency of the product production process is improved, and the improvement of the product quality is facilitated.
The invention provides a tracing method of feminine hygiene products based on a block chain, which is characterized in that corresponding associated data are obtained through an execution main body at each stage of the circulation process of the feminine hygiene products in the block chain, and the associated data are uploaded to the block chain to be stored so as to realize data storage of the block chain. The technical characteristic that the data in the block chain cannot be arbitrarily tampered can be fully exerted, so that the authenticity and the reliability of the associated data are guaranteed, the reliability of a user on a product is further improved, and the brand image of the feminine hygiene product is favorably improved. In addition, each product corresponds to a specific digital object unique identifier, so that a user can conveniently inquire the associated data of the feminine hygiene product through terminal equipment such as a mobile phone, a computer and the like, and good user experience is provided for the user. The associated data contain the production data of each stage in the production process of the feminine hygiene product, so that a user can know more visually each stage in the production process of the product, and the associated data stored in the block chain are compared with the product data obtained in the actual purchase process of the user, so that the authenticity of the purchased product can be judged very easily, the user is prevented from being cheated, and the benefit of the user is guaranteed not to be lost.
