Description

Technical Field

[0001] This invention relates to the field of traceability technology for traditional Chinese medicine instruments, specifically to a blockchain-based intelligent traceability method and system for the entire lifecycle of traditional Chinese medicine cupping therapy. Background Technology

[0002] Cupping therapy is an important component of Traditional Chinese Medicine (TCM) treatment. It stimulates acupoints on the body surface with localized negative pressure, offering various therapeutic effects such as pain relief and improved blood circulation. However, its effectiveness and safety are highly dependent on the quality of the cupping jars, the environment in which they are used, and the standardization of the operating procedures. Currently, the production, inspection, distribution, and use of TCM cupping jars are scattered among manufacturers, distributors, medical institutions, and users at various levels. Information recording relies heavily on manual processes or centralized databases, resulting in data silos, incomplete records, and delays, making it difficult to achieve accurate traceability throughout the entire lifecycle from source to clinical application.

[0003] Traditional traceability systems often employ a centralized architecture, with data storage and access limited to a single management platform. This makes them susceptible to tampering or loss, and as the number of participants increases, their scalability and interoperability become insufficient, making it difficult to cope with complex supply chain scenarios. Similarly, in the supply chain of traditional Chinese medicine, due to the numerous stages including planting, processing, warehousing, transportation, and use, the information sources are heterogeneous and the stages span a wide range. The lack of a unified and efficient end-to-end tracking and monitoring mechanism results in significant regulatory difficulties and low efficiency.

[0004] In summary, the current lifecycle management of traditional Chinese medicine cupping still faces challenges such as data silos, tampering, traceability gaps, and insufficient privacy protection. There is an urgent need for an innovative solution to build a safe, transparent, and intelligent full lifecycle traceability system. Summary of the Invention

[0005] Technical Objective: To address the shortcomings of existing technologies, this invention discloses a blockchain-based intelligent traceability method and system for the entire lifecycle of traditional Chinese medicine cupping therapy. By collecting key information at each stage of cupping therapy production, transportation, and use, and using blockchain as a carrier for encrypted storage and intelligent verification, the authenticity and immutability of the information are guaranteed throughout the entire lifecycle.

[0006] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0007] A blockchain-based intelligent traceability method for the entire lifecycle of traditional Chinese medicine cupping therapy includes the following steps:

[0008] S1. Register the fire cupping and related entity information, including assigning a unique identifier to the fire cupping and registering the identities of each participating party;

[0009] S2. Collect environmental parameters and usage data at each stage of the production, distribution and use of fire cupping;

[0010] S3. The collected environmental parameters and usage data are locally encrypted and used to generate transaction information that can be uploaded to the blockchain.

[0011] S4. Broadcast the transaction information to the blockchain network and verify it through the consensus mechanism;

[0012] S5. After successful verification, the transaction record is written into the blockchain ledger;

[0013] S6. Calculate the credibility index of the entire lifecycle information based on the on-chain records and update the storage;

[0014] S7. Respond to the query request and provide the full life cycle traceability information of the cupping device according to the user's permissions.

[0015] Preferably, in step S2, IoT sensor devices are used to collect environmental parameters such as temperature, humidity, and pressure in real time, as well as dynamic data during the use of the cupping jar, and the collected data is associated with the unique identifier of the cupping jar.

[0016] Preferably, step S3 further includes calculating a data digest and a digital signature to ensure data integrity, and using symmetric or asymmetric encryption algorithms to improve security during data transmission.

[0017] Preferably, the lifecycle credibility index E is calculated using the following formula:

[0018] ,

[0019] Where E is the credibility index throughout the entire lifecycle, M is the number of information collection stages, and i is the index of the information collection stage. Let be the weighting coefficient for the i-th stage of information collection. Let be the delay time for uploading information to the blockchain during the i-th stage of information collection, and b be the time sensitivity coefficient.

[0020] A blockchain-based intelligent traceability system for the entire lifecycle of traditional Chinese medicine cupping therapy is provided to implement the blockchain-based intelligent traceability method for the entire lifecycle of traditional Chinese medicine cupping therapy described above. The system includes: a registration module, a data acquisition module, a blockchain network module, a data processing module, and a query module, wherein:

[0021] The registration module is used for each participating party to register in the system and to assign a unique identifier to the fire cupping device and each party's main entity;

[0022] The data acquisition module is used to collect environmental and usage parameters at each stage of the production, distribution, and use of the fire cupping device;

[0023] The data processing module is used to encrypt and package the collected data and generate on-chain transaction information;

[0024] The blockchain network module, consisting of multiple nodes, is used to perform consensus verification of the transaction and write the verified data records into the blockchain ledger.

[0025] The query module is used to receive query requests and read and return the full life cycle traceability information of the cupping jars from the blockchain according to the query conditions.

[0026] Preferably, the data processing module further includes a credibility calculation unit, used to calculate the credibility index of each traceability information and write it onto the chain along with the corresponding record.

[0027] Preferably, each node in the blockchain network module is set as a production enterprise, a regulatory agency, and a medical institution entity, and the consensus verification mechanism is a multi-signature or Byzantine fault tolerance mechanism, so that on-chain data can only be written after being confirmed by multiple parties.

[0028] Preferably, the data acquisition module includes a sensor-based Internet of Things (IoT) device for real-time acquisition of key parameters during storage, transportation, and use, and for associating the data with the unique identifier of the fire cupping jar before transmitting it to the data processing module.

[0029] Beneficial Effects: The blockchain-based intelligent traceability method and system for the entire lifecycle of traditional Chinese medicine cupping provided by this invention has the following beneficial effects:

[0030] 1. This invention significantly improves the integrity and verifiability of traceability information by comprehensively collecting and storing key data at each stage of production, distribution, and use on the blockchain. Specifically, the system's data acquisition module uses sensor devices to acquire environmental and usage parameters such as temperature, humidity, and pressure in real time, and associates them with the unique identifier of the fire cupping jar, ensuring seamless connection and holographic recording of data at each stage. Combined with the full lifecycle credibility assessment formula proposed in this invention, the timeliness and weight of data at each stage can be dynamically quantified and verified, ensuring that each on-chain record has a quantifiable trust index, thereby eliminating the "information silos" and tampering risks in traditional centralized systems.

[0031] 2. This invention employs a blockchain network module to jointly maintain a distributed ledger by various parties (manufacturing enterprises, regulatory agencies, medical institutions, etc.) as nodes. Through multi-signature or Byzantine fault-tolerant consensus mechanisms, transaction information is written after multi-party confirmation, greatly improving data immutability and audit transparency. Simultaneously, the system's query module can output real-time traceability information of the entire lifecycle of the cupping jars from manufacturing to use, according to user permissions. This allows regulatory and clinical personnel to access reliable and complete historical records at any time, significantly improving regulatory efficiency and medical safety.

[0038] The present invention will now be described more clearly and completely by way of a preferred embodiment in conjunction with the accompanying drawings, but this does not limit the invention to the scope of the described embodiment.

[0039] like Figure 1 As shown, a blockchain-based intelligent traceability method for the entire lifecycle of traditional Chinese medicine cupping therapy includes the following steps:

[0040] S1. Register the information of the cupping jars and related entities, including assigning a unique identifier to the cupping jars and registering the identities of each participating party.

[0041] In one specific embodiment, during the system initialization phase, Hyperledger Fabric Certificate Authority (CA) is used to register digital identities for participants such as manufacturers, regulatory agencies, medical institutions, and logistics providers. The CA generates a public-private key pair for each entity and manages its certificate and role attributes within the Membership Service Provider (MSP) to achieve node identity authentication and access control. On the cupping production line, a globally unique asset ID based on UUID or GS1 standard is generated through the MES system. The CreateAsset interface in the Fabric "AssetTransfer" Chaincode is then called to write this ID and initial metadata into the world state, achieving a one-to-one binding between off-chain physical cupping jars and on-chain assets. In the Fabric network's Channel configuration, an Access Control List (ACL) policy is defined, granting production nodes write permissions for production transactions, regulatory nodes query and approval permissions, and treatment nodes write usage records, ensuring that each node can only access data and contract functions within its authorized scope.

[0042] S2. Collect environmental parameters and usage data at each stage of the production, distribution and use of fire cupping.

[0043] In one specific embodiment, during the production process: industrial cameras are deployed on the production line to read text and structured data such as production batch, material batch number, and production time via the OPC UA protocol, and to acquire images of the appearance of the fire cups to generate a quality acceptance report.

[0044] In the distribution process: LoRaWAN / NB-IoT sensors are used to collect temperature, humidity, vibration and GPS positioning data in real time in transport vehicles and warehousing environments. These data are then associated with the unique ID of the fire canister through an edge gateway to achieve dynamic monitoring and location tracking of the logistics environment.

[0045] Usage: RFID / NFC readers and temperature / pressure sensors are deployed in TCM clinics to record key parameters such as the number of cupping sessions, heating temperature curves, and duration of each session, along with the operator's ID, and uploads this data to an edge server via local Wi-Fi.

[0046] S3. The collected environmental parameters and usage data are locally encrypted and used to generate transaction information that can be uploaded to the blockchain.

[0047] In one embodiment, at the edge node, the multimodal fusion formula is first applied...

[0048]

[0049] in This is a fusion digest used for blockchain on-chain processing. It compresses multi-source information while ensuring that each modal feature is integrated in a set proportion, and can be directly used as evidence of transaction content. The total number of modalities participating in the fusion of this invention includes, but is not limited to, production metadata (such as batch number, material identifier), appearance image features (such as defect detection indicators), and environmental sensor summaries (such as temperature, humidity, vibration statistics). j represents the modal index participating in the fusion of this invention. This is a summary generated after edge node preprocessing for the j-th mode, representing the core features of the fire cupping quality or usage at this stage. The weighting coefficients set in this invention for the j-th mode are used to reflect the importance of the mode in determining the safety or authenticity of the cupping. For example, production stage information can be given a higher weight, and usage stage environmental parameters can be given a medium weight.

[0050] The collected text summaries, image features, and sensor data are weighted and fused to generate compact summaries, thereby reducing on-chain storage requirements.

[0051] Subsequently, an adaptive differential privacy perturbation is introduced for privacy-sensitive data:

[0052]

[0053] in This is the summary generated after edge node preprocessing for the j-th mode. The privacy protection strength parameter applied to the j-th type of data is dynamically set according to the privacy level at different stages such as production, distribution, and use. For example, patient identification information in clinical usage logs requires higher noise levels, while production batch numbers can be set to lower noise levels to ensure that privacy protection is achieved locally while maintaining statistical usability. This invention uses Gaussian noise to perturb sensitive digests, preventing on-chain data from leaking specific privacy information. The perturbated summary is used for on-chain transactions, which retains the statistical characteristics of the original summary while achieving privacy protection within a controllable noise level.

[0054] Finally, the encrypted digest, asset ID, timestamp, and digital signature are encapsulated into a transaction proposal. The submitTransaction() method is called through the Fabric SDK to sign the transaction and prepare it for submission to the endorsing node.

[0055] S4. Broadcast the transaction information to the blockchain network and verify it through the consensus mechanism.

[0056] The client sends a transaction proposal to the designated endorsing peers. The peers perform chaincode simulation and return an endorsement signature to satisfy the endorsement policy (e.g., "Org1MSP.peer AND Org2MSP.peer"). After the endorsement is completed, the ordering service nodes (based on PBFT or multi-signature mechanisms) sort the endorsed transactions and reach a consensus to form new block candidates, ensuring that all nodes in the network have a consistent understanding of the transaction order.

[0057] The consensus-reached block is broadcast to all peer nodes by the Ordering Service. Each peer verifies the legality of the transaction and the endorsement rules after receiving it, and prepares to write it into the ledger after confirming that there are no errors.

[0058] S5. After successful verification, the transaction record is written into the blockchain ledger.

[0059] Peer nodes perform verification on a transaction-by-transaction basis within a consensus block, including signature verification, endorsement policy checks, and version conflict detection. Once verification is successful, the block is appended to the ledger and the World State database, thus achieving data tamper-proofing and audit trail recording.

[0060] All historical transactions and the latest asset status are persistently stored in LevelDB / CouchDB. Users or regulators can trace back the entire lifecycle data of any Huoguan ID through the block query interface, ensuring that the information is verifiable.

[0061] S6. Calculate the credibility index of the entire lifecycle information based on the on-chain records and update the storage.

[0062] Embed trust assessment logic in the smart contract and call the formula.

[0063]

[0064] Where E is the credibility index throughout the entire lifecycle, M is the number of information collection stages, and i is the index of the information collection stage. Let be the weighting coefficient for the i-th stage of information collection. Let be the delay time for uploading information to the blockchain during the i-th stage of information collection, and b be the time sensitivity coefficient.

[0065] The credibility calculation result is written back to the corresponding transaction or asset attribute field by the smart contract, forming a dynamic credibility tag on the chain for subsequent querying and automated auditing.

[0066] S7. Respond to the query request and provide the full life cycle traceability information of the cupping device according to the user's permissions.

[0067] Users submit query requests via Fabric SDK or RESTful API. The client completes authentication by carrying the registered identity signature. Peer nodes determine the caller's permissions based on MSP and ACL policies and then execute evaluateTransaction to query the Chaincode, returning all transaction records and trust values ​​corresponding to Huoguan.

[0068] The application layer can display the cupping life cycle map, credibility heat map and early warning prompts in the front-end dashboard, and can trigger the anomaly detection and statistical analysis functions of smart contracts to provide real-time and reliable data support for regulatory and clinical decision-making.

[0069] like Figure 4 The diagram illustrates the lifecycle evolution of cupping therapy across three stages (production → transportation → use), visually presenting the sequential relationship of each stage using equipment icons and process arrows. Figure 5 The credibility heatmap uses the vertical axis to represent different bottling assets and the horizontal axis to represent time. The grid color changes from dark blue (low credibility) to dark red (high credibility), visually reflecting the credibility trend of each asset over its lifecycle.

[0070] like Figure 2 As shown, a blockchain-based intelligent traceability system for the entire lifecycle of traditional Chinese medicine cupping therapy is used to implement the blockchain-based intelligent traceability method for the entire lifecycle of traditional Chinese medicine cupping therapy described above. The system includes: a registration module, a data acquisition module, a blockchain network module, a data processing module, and a query module, wherein:

[0071] The registration module is used for each participating party to register in the system and to assign a unique identifier to the fire cupping device and each party's main entity.

[0072] The registration module is used to initialize the digital identities and asset identifiers for the cupping jars and all participating parties during the initial system deployment. Specifically, participating parties such as manufacturers, regulatory agencies, medical institutions, and logistics providers use the registration module to call the identity management service to complete certificate issuance and role configuration; at the same time, a globally unique identifier is generated for each cupping jar, and initial metadata is registered on the blockchain to achieve a one-to-one binding between the physical cupping jar and the on-chain asset.

[0073] The data acquisition module is used to collect environmental and usage parameters at each stage of the production, distribution, and use of fire cups.

[0074] The data acquisition module covers the three stages of production, distribution, and use of the cupping device, collecting key environmental and usage parameters in real time. In the production stage, production batch numbers, material batch numbers, and appearance images are acquired via industrial cameras and PLC interfaces. In the distribution stage, sensors for temperature, humidity, vibration, and GPS are deployed to monitor the transportation and storage environment. In the usage stage, the diagnostic terminal records the number of uses, temperature curves, and usage duration via RFID / QR code scanning and temperature and pressure sensors, transmitting the raw data to edge nodes.

[0075] The data processing module is used to encrypt and package the collected data and generate on-chain transaction information.

[0076] The data processing module, located on the edge computing node, is responsible for preprocessing, protecting privacy, and packaging transactions into the collected multimodal raw data. First, it weights and fuses production metadata, image features, and environmental summaries according to preset weights to generate a compact summary. Then, it adds differential privacy perturbations or encryption protection to sensitive data. Finally, it encapsulates the processed summary, cupping identifier, timestamp, and digital signature into a blockchain transaction proposal and submits it to the endorsing node.

[0077] The blockchain network module, consisting of multiple nodes, is used to perform consensus verification on the transactions and write the verified data records into the blockchain ledger.

[0078] The blockchain network module consists of several consortium nodes, including production nodes, regulatory nodes, medical nodes, and ordering service nodes, responsible for consensus verification of transactions and ledger maintenance. Endorsing nodes receive transaction proposals, perform simulations, and return signatures; ordering service nodes order endorsed transactions, reach consensus, and generate new blocks; peer nodes verify the blocks and write them into the ledger and state database, ensuring distributed notarization and immutability of data throughout the entire lifecycle of cupping therapy.

[0079] like Figure 3 The diagram illustrates the division of responsibilities among the nodes in a consortium blockchain, including production nodes responsible for endorsing production data, regulatory nodes responsible for consensus and auditing, and medical nodes responsible for uploading usage data to the blockchain and providing query services.

[0080] The query module is used to receive query requests and read and return the full life cycle traceability information of the cupping jars from the blockchain according to the query conditions.

[0081] The query module provides system users with permission-based full lifecycle traceability query and early warning functions. After authenticating with their digital identity, users can initiate query requests. The system extracts all transaction records and credibility indicators of the specified cupping jar from the blockchain according to the ACL policy and displays them in the front-end interface in the form of graphs or lists. When the credibility index drops sharply or reaches the preset scrapping threshold, the query module will trigger an early warning prompt to notify the administrator or clinical staff to handle the situation in a timely manner.

[0082] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
