The terms "comprises" and "comprising" indicate the presence of the described features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides a method for drug traceability management based on a block chain technique, including:
s10, acquiring identity information of a plurality of block chain nodes and medicine information supplied by each block chain node;
it should be noted that the blockchain technology is a novel decentralized protocol, and can securely and distributively store various digital information, and the stored information cannot be forged or tampered, and can automatically execute a preset intelligent contract without any auditing of centralized mechanisms. The basic idea based on block chain tracing is mainly as follows: establishing digital and physical links, endowing each medicine with a unique digital ID, registering the full life cycle information of the medicine, including information of each link from early development, test, approval, production, quality inspection, purchase, storage, transportation, inoculation and the like of the medicine, and information of related responsible persons of each node of supervision departments, quality inspection departments, raw material suppliers, medicine production enterprises, sellers, storage logistics enterprises, hospitals and the like in real time, and achieving transparent disclosure, strict record, legal specification and public supervision of medicine chain information.
The traceability based on the block chain has at least the following advantages compared with the traditional traceability of the internet of things: firstly, a block chain provides a new tool for traceability anti-counterfeiting, the block chain has a decentralized characteristic, does not depend on a certain organization and an individual, and utilizes a credible technical means to publicly record all information in a distributed accounting system, data on the chain has a timestamp and can not be tampered, so that the 'trust problem' in the traditional traceability business can be solved, and the counterfeiting cost of an enterprise is increased; and in addition, the distributed storage of the block chain ensures that the data is completely protected. Secondly, all the parties participating in the medicine ecological chain under the consensus mechanism can carry out cooperative supervision on the whole chain, and the 'hidden box operation' of 'an independent character' is prevented. For example, the existing block chain traceability application basically adopts the design of a federation chain, changes the original 'one center' into a structure of 'a plurality of centers', and forms a trusted 'ecosphere' by the plurality of centers. And finally, an intelligent contract can be generated based on the block chain, ownership of the medicine and ownership of the disposal right are determined in real time, the whole supply chain is more automated, the data of the supply chain are kept to be public and transparent in real time, once a problem is found, the problem can be tracked in real time even through cross-industry circulation, the problem can be effectively traced and the loss can be prevented, and the reliability of a management system is enhanced.
In this step, a plurality of block chain nodes are established, and the block chain nodes include pharmaceutical factories, drug stores and hospital terminals, and of course, other departments related to medicines, such as raw material suppliers, medicine production enterprises, sellers, storage logistics enterprises and the like, can also be used as the block chain nodes. And the more participants, the larger the corresponding medicine information is, the more traceable nodes are during medicine tracing, and the tracing range is wider.
Further, the drug information includes: the method comprises the steps of obtaining medicine production information, medicine circulation information and medicine detection information, wherein the medicine production information comprises medicine raw material information and medicine production time information; the medicine circulation information comprises health information, production equipment information and production environment information; the drug detection information comprises drug delivery detection certificates, third-party detection agency certificates and supervision department certificates. It can be understood that departments associated with various information of medicines are different, and recording information in all processes of production, circulation and detection is important for perfecting traceability information. For example, the pharmaceutical material information may originate from various pharmaceutical material supply companies, manufacturers, or be authorized for direct purchase from the grower. The production time information of the medicine and the corresponding shelf life and use information should be clearly recorded. More related to medicine circulation are sellers and warehouse logistics enterprises, medicine detection information needs a medicine factory detection certificate, a third-party detection institution certificate and a supervision department certificate, and once a detection problem occurs, a person can trace back to related quality control departments at the first time.
S20, associating a unique drug identification code for the drug information, and uploading the associated drug information to the block chain node;
in the step, a unique medicine identification code is associated with each medicine, the identification code is any one of a two-dimensional code, a bar code or an RFID label, and then the identified medicine information is uploaded to each block chain node so that the block chain node can backup the initial information of the medicine. Wherein, the identification code is the only ID of every medicine, when the medicine circulates to next node from a node, the circulation information or the monitoring information of medicine can change, and the medicine receiving terminal can control and sweep the sign indicating number rifle and scan the medicine identification code, perhaps utilizes cell-phone APP bar code intelligent recognition function to discern above-mentioned medicine identification code. Then, according to the medicine identification code, acquiring related data, and updating the database according to the acquired last related node information, for example, circulating from a quality inspection department to a distributor, the quality inspection department can firstly acquire medicine production information and previous circulation information through identification code identification, after the comparison is correct, the medicine is detected, after the medicine is qualified, monitoring information of the medicine is filled and uploaded to the database, when the medicine is circulated to the distributor, the information in all previous flows can be directly acquired only by scanning the identification code, and as long as each node ensures timely supplement and update of the information, the information and related units of each link of the medicine can be completely recorded.
It should be noted that in this step, uploading the medicine information of the associated identification code to each blockchain node is to backup a complete piece of data, prevent the information tampering phenomenon in advance, and be supervised by each node together, and by using the data and combining with the machine learning related algorithms, such as a support vector machine, a convolutional neural network, a deep neural network, and the like, model training and actual system testing are performed on specific abnormal behaviors, and once the abnormal tampering, stealing, and the like occur, the phenomena can be checked in time, so that the safe and stable operation of the system is ensured.
S30, authenticating the identity information of the currently accessed block link node, and determining drug traceability information when the authentication is passed;
in this step, it can be understood that, when the identity information of the blockchain node is obtained in step S10, the central data management platform manages and stores the identity information of each blockchain node, and when the blockchain node wants to access the central data management platform, authentication is first required, where the authentication may be performed by setting an account for an enterprise, a hospital, a pharmacy, a pharmaceutical factory, and the like, logging in through an account password for authentication, and when the authentication is passed, the identity information of the blockchain node can be accessed and the information of the drug to be traced is locked; further, when the authentication fails, the authentication failure message is pushed to the currently accessed block link point in a short message or mail mode, if the account password is wrongly filled or the record is modified, the authentication failure message can be retrieved through the security center, if the current node records the information again, the information is wrongly or changed, the information can be fed back in time, and the central data management platform can record or modify the information again.
S40, according to a preset intelligent contract, constructing a drug circulation transaction between the block chain link points passing the authentication, and updating the drug traceability state recorded by the block chain link points;
it should be noted that the intelligent contract is a built-in contract formed by an algorithm code based on a rule agreed in advance, and the automation and the intelligence of the performance can be realized by setting the intelligent contract on the block chain. According to the block chain-based medicine traceability method, intelligent contracts to be subjected to chain winding are public, each node on the medicine traceability block chain can check the intelligent contracts to be subjected to chain winding, and whether the intelligent contracts to be subjected to chain winding meet the agreement is checked; and uniformly sending the audited intelligent contracts to be linked to each node of the medicine tracing source block chain to form the medicine tracing intelligent contracts. Meanwhile, drug information is associated with the drug tracing code and uploaded to the drug tracing block chain. The consumer or other demander can inquire the information of the medicine, such as raw materials of the medicine, production inspection condition, detection certificate and the like, by a certain mode, such as code scanning.
Because the intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, and once the intelligent contract is deployed, the intelligent contract can only be executed through a program without human factor interference, so that the stability and the credibility of the medicine information data are enhanced. Meanwhile, data on the drug traceability block chain are data which can not be tampered, and the public trust and traceability of drug information are guaranteed.
It can be understood that, in order to timely grasp the position and the current state of the medicine, the medicine tracing status recorded in the block link points is continuously updated, and the medicine tracing status includes: the warehouse-out state information, the warehouse-in state information, the goods returning state information and the scrapping state information specifically comprise:
when detecting that the medicine is stored in a local medicine library, generating warehousing state information corresponding to the medicine; the warehousing status may be: warehousing and warehousing;
when detecting that the medicine leaves a local medicine library, generating ex-warehouse state information corresponding to the medicine; the ex-warehouse status may be: going out of the warehouse and going out of the warehouse;
when detecting that the medicine enters a transportation state, generating transportation state information corresponding to the medicine; the transportation state is mainly in the middle of transportation and reached; displaying the geographical position of the transportation and the reached target position;
and when detecting that the medicine is expired or invalid, generating scrapping state information corresponding to the medicine.
And S50, responding to the query request for the drug tracing information, and pushing the acquired query result to an access terminal.
The embodiment of the invention ensures that the medicine data cannot be falsified, is not easy to leak and is convenient to query by applying the block chain technology, and simultaneously sets a plurality of drugstores, pharmaceutical factories and hospitals as the block chain nodes, thereby realizing the full-element datamation of the whole life cycle of the medicine from production, circulation and detection, ensuring the authenticity of the data and improving the medicine tracing efficiency.
