Alternatively, in the present embodiment, the first result information includes first identity description information, first result description information, and first article description information of the first object, it is to be understood that the first identity description information, the first result description information, and the first article description information relate to the first object, for example, in the case where the first object includes a plant, the first identity description information may be but is not limited to include the genus of the plant, the name of the plant, etc., the first result description information may be but is not limited to describe yellowing of leaves of the plant, the height of the plant, etc., the first article description information may be but is not limited to include fertilizer a, once weekly use of 20g, fertilizer b, once every three days use of 40g.

For 0.ltoreq.v.ltoreq.n, if S [ i, v ] and S [ v, j ] are greater than a threshold, the class to which the sensitive cluster corresponds is the class (or called sensitive type) corresponding at the location.
For example, the bank's column corresponds to a value of 1 and the row's column corresponds to a value of 1, both of which are greater than the corresponding threshold (e.g., both are 0.8), then from the beginning of the transaction to the end of the transaction is a sensitive vocabulary, i.e., psoriasis is one of the information sets to be filtered. The bank disease column has a value of 1, the disease row has a value of 1, and both values are larger than the corresponding threshold (for example, both values are 0.9), so that psoriasis is information belonging to the sensitive type of disease.
As an alternative example, the method further includes: training the pre-training module through a target loss function, and adjusting at least one of an initial weight matrix, an initial query weight matrix, an initial key weight matrix and an initial value weight matrix under the condition that the loss value of the function value output by the pre-training module is larger than a preset loss value threshold; and under the condition that the loss value of the function value output by the pre-training model is smaller than or equal to a preset loss value threshold, ending training of the pre-training model, determining an initial weight matrix at the time of ending training as the weight matrix, determining an initial query weight matrix at the time of ending training as the query weight matrix, and determining an initial value weight matrix at the time of ending training as the value weight matrix.
Alternatively, in the present embodiment, training may be performed using, but is not limited to, a binary cross entropy function, as it has a unique global minimum. This helps the optimization algorithm (e.g., gradient descent) more easily find the best model parameters. The pseudo code corresponding to the loss function is:
# pseudo code example
def binary_cross_entropy(y_true, y_pred):
epsilon=1e—15# is a small value for preventing log (0), usually set to a small positive number;
y_pred=clip (y_pred, epsilon, 1-epsilon) # limits the probability value to the [ epsilon, 1-epsilon ] range;
return - (y_true * Log(y_pred) + (1 - y_true) * Log(1 - y_pred))。
in such a way, the multi-layer self-attention mechanism extracts the medical diagnosis and the complex interaction mechanism of the sensitive information on the chain, so that the selective disclosure of the information is realized, and for the selective disclosure module, a highly intelligent sensitive information shielding method based on a pre-training model is provided, and the content irrelevant to the transaction in the information is accurately identified and filtered through a deep learning network model so as to ensure the security of privacy. In the selective disclosure module, the feature representation balances the requirements of privacy protection and data integrity and usability of the sensitive information through serial category representation and sequence representation, ensures that potential sensitive information cannot be revealed in the information extraction process, and simultaneously maintains the comprehensiveness and usability of the data. In addition, in the selective disclosure module, the interactive form adopts a multi-layer self-attention mechanism, so that a complex interactive mechanism between medical diagnosis and on-chain sensitive information is finely captured, and a highly intelligent solution is provided for selective disclosure of information, thereby ensuring that private information is fully protected, and simultaneously meeting the effective disclosure of information to be shared. In the selective disclosure module, decoding and filtering realize accurate classification of diagnosis text contents by accurately extracting effective information in the interactive form, thereby providing key support for accurate processing and analysis of medical data and ensuring credibility and efficiency of medical decision.

FIG. 7 is a second schematic diagram of an alternative blockchain-based information interaction method, as shown in FIG. 7, that may be illustrated and described, but is not limited to, using the example in which the first object includes a patient, in accordance with embodiments of the present application. The main functional modules of the blockchain-based digital medical application platform include entity identity services, medical data transmission, medical data analysis, medical credentials, medical data administration, smart contracts, and selective disclosure. May include, but is not limited to, the following:
(1) The entity identity service module uses a distributed Digital Identity (DID) technology to create a unique identity of a user, provides services such as entity identity DID registration, identity verification, identity inquiry and updating, and the like, and supports cross-platform and cross-region safe and trusted interaction of entity digital identity data.
(2) The medical data transmission module uses a blockchain technology and Encryption communication to encrypt and transmit medical data to a blockchain, and an Attribute-Based Encryption technology, such as Ciphertext-Policy-Based Attribute Encryption (CP-ABE for short), can be adopted to formulate a Ciphertext access Policy, and only authorized users can decrypt and access the data. The module allows safe transmission and sharing of medical data and ensures privacy and integrity of the data in the transmission process.
(3) The medical data analysis module analyzes the medical data to extract valuable information, aid in medical decisions and research. The module designs a personal sensitive data shielding and erasing mechanism, and realizes automatic detection and shielding of private data by utilizing intelligent contracts; the data sharing incentive mechanism is designed to allow the desensitized data to be used by data processing modules (e.g., data analysis, AI model training, etc.). Meanwhile, based on a flexible right-determining and authorizing mechanism and a secure multiparty computing method, the data is safely and reasonably used on the basis of the right to which the data belongs, and the privacy protection effect of 'data availability and invisible' is truly achieved.
(4) The medical credential module uses trusted credential VC (Verifiable Credential) technology to store medical data in a digital credential mode up-chain. These credentials can be verified on the blockchain, ensuring the source and integrity of the data. The created trusted medical credential serves as a digital certificate for medical data for the patient, doctor and other participants to verify the authenticity of the data. Meanwhile, the selective information disclosure certificate is supported Based on technologies such as zero knowledge proof, DPKI (Decentralized Public Key Infrastructure, distributed public key infrastructure), CP-ABE (ciphertex-Policy Attribute-Based Encryption) algorithm, homomorphic Encryption and the like.
(5) The medical data administration module uses smart contracts to implement access control and data sharing policies that ensure that only authorized users can access specific data. The module ensures compliance and privacy protection of medical data, and manages access and use of the data.
(6) The smart contract module is intended to automate and enforce specific business rules, ensuring that data exchanges and transactions are performed efficiently and consistently. The module writes intelligent contracts by using an intelligent contract platform based on alliance chains (such as FISCO BCOS and HyperLedger Fabric), and ensures that data interaction follows predefined rules on the basis of safe and reliable contract programs.
The selective disclosure module identifies and filters the content irrelevant to the transaction in the information through the deep learning network model, so that privacy security is ensured. The module stops providing a novel calculation method to realize accurate filtration.
Medical data may contain sensitive information such as personal identity, medical history, and diagnostic results, and it is desirable to be able to automatically detect and mask such sensitive data to ensure that patient privacy is adequately preserved. However, the related art has not achieved sufficient reliability in this respect. Furthermore, medical data transactions require a balance between anonymity and traceability. The transparency of the blockchain allows all transactions to be traced, which can threaten patient privacy. While anonymization measures may be taken, there are challenges in protecting patient privacy while ensuring the integrity of medical data, privacy and security have been paramount issues in the medical data transaction framework, and there is a continuing need to improve and strengthen related technologies to meet regulatory and patient privacy protection requirements.
The embodiment of the application provides a data privacy protection transaction framework based on a deep learning technology for a block chain transaction platform. The method can effectively ensure privacy in interaction process of multiple entities such as patients, doctors, pharmacies and the like, and realize erasure and desensitization of sensitive data of the patients. Providing a safe and reliable medical data transaction environment for patients, doctors and other participants. The main functional modules of the blockchain-based digital medical application platform comprise entity identity services, medical data transmission, medical data analysis, medical certificates, medical data supervision, intelligent contracts and the like. Users of the platform include patients, doctors, hospitals, pharmacies, and pharmaceutical enterprises. The functional modules together construct a powerful digital medical application platform, and the automatic detection and shielding capability of private data is particularly concerned to ensure that the privacy of a patient is fully protected. In particular, for selective disclosure modules, it is desirable to insist on maintaining the security of medical data, enhancing privacy protection, while ensuring compliance of the data. The implementation of the method is not only beneficial to the sensitivity screening of sensitive information, but also provides a layer of credible protection for the data processing in the medical field so as to meet the requirements of regulations and patient privacy.
For example, in the context of an application scenario for acquiring prescription credentials and pathology, the steps may include, but are not limited to:
1. patient registration and authentication: a first object (e.g., patient a) registers with the medical data platform and verifies its identity through a first object account number (e.g., distributed Digital Identity (DID)). This DID will become the unique identification of patient a on the platform.
2. Prescription is made by doctors: patient a felt uncomfortable and reserved a third subject (e.g., doctor B). Doctor B logs on to the platform and, based on the symptoms and diagnosis of patient a, prescribes her. The prescription contains detailed information (corresponding to the first outcome information) of the desired drug.
3. Generating prescription vouchers: a prescription credential (corresponding to the first information credential) is automatically generated for patient a via the smart contract on the platform. The prescription voucher includes selectively revealed prescription related information including first item description information, e.g., medication name, dosage, usage, etc. Irrelevant sensitive information (or information that is of a sensitive type), including patient personal information, disorders, disease course, etc., is filtered out. This prescription voucher is created using verifiable digital Voucher (VC) technology and is associated with the DID of patient a.
4. Credential authorization and access: patient a may choose to grant the prescription voucher to a specific second object (e.g., pharmacy C) in order to obtain the medication. Patient a may set access rights to prescription credentials through smart contracts, ensuring that only authorized entities (or, referred to as, object account numbers) can view and use the credentials.
5. Drug store verification and drug delivery: patient a goes to a pharmacy where her current access portal information (e.g., a two-dimensional code of the prescription voucher) can be scanned to verify the authenticity and validity of the prescription voucher.
6. Case access: at the same time, doctor B may also create a case record of patient a on the platform, including symptoms, diagnosis, treatment planning, etc. These case data are correlated with the DID of patient a to form a digital case record.
7. Case data sharing: patient a may choose to share her case data with other doctors or hospitals to get more comments and advice. Patient a may control the sharing scope of data by setting access rights to the credentials.
Through this application scenario, patient a can securely acquire prescription vouchers and case data on a federation chain based smart medical data platform while protecting her privacy and data security. The doctor can easily create and manage case data through the platform and share information with the patient. Such blockchain-based applications may provide a more efficient, transparent, and secure way of medical data management and exchange.
In this way, the entity identity service module creates unique identity using distributed Digital Identity (DID) technology to support cross-platform, cross-regional entity digital identity data interactions. The medical data transmission module ensures the safe transmission of medical data by using a blockchain technology and encryption communication, and implements data access control based on an attribute encryption technology so as to protect the privacy and the integrity of the data. The medical data analysis module designs a shielding and erasing mechanism of personal sensitive data, realizes automatic detection and shielding of private data through intelligent contracts, supports a data sharing excitation mechanism, and ensures that the desensitized data is used in compliance. The medical credential module uses trusted credential (VC) technology to store medical data in a digital credential mode up-link to verify the origin and integrity of the data and to support selective information disclosure credentials to protect data privacy. The medical data administration module enforces access control and data sharing policies using smart contracts to ensure that only authorized users can access specific data and to administer compliance and privacy protection of the data.
Privacy protection for medical data, secure sharing of medical records, and support for medical decisions. Sensitive data of the patient may be masked, ensuring that medical institutions and researchers have access to the necessary information while protecting the privacy of the patient. This alliance-chain-based intelligent medical consultation scheme has profound significance in the medical field, not only concerning privacy protection of patients, but also concerning advances and improvements in hospitals, pharmacies and the whole medical system. For patients, this innovative application ensures that the privacy of their medical data is effectively protected, which is a key step in establishing trust and protecting personal privacy. Patient sensitive data can be masked but at the same time medical institutions and researchers can access the necessary information, which means more accurate diagnosis and treatment advice, improving the quality and effectiveness of medical services. Patients can share their medical records more confidently, knowing their privacy is well protected, which will encourage more people to actively participate in medical research and treatment protocols. For hospitals and medical facilities, this technology provides data security and compliance assurance. Hospitals can reduce the risks of data leakage and unauthorized access, and further improve the credibility of medical institutions. In addition, through better medical data analysis and decision support, hospitals can provide higher-quality medical services, improve patient satisfaction, and realize improvement of medical efficiency. A pharmacy can also benefit from it. They can obtain more accurate patient medical record information and ensure the correct formulation of the medicine, thereby reducing the risk of incorrect use of the medicine and protecting the health of the patient. In addition, the pharmacy may provide more personalized patient services, providing customized medication and health advice based on the patient's medical history and needs. The application is helpful for promoting medical informatization construction, improves the quality and efficiency of medical service, and enables medical resources to be distributed more reasonably. The medical data management system can better monitor the use and sharing of medical data, ensure that all parties such as medical institutions, pharmacies and the like obey regulations in terms of data processing, and ensure the rights and interests and privacy of patients. The method promotes innovation and development of the medical industry, promotes development of more scientific researches, and is beneficial to improvement and optimization of the medical field. In conclusion, the intelligent medical inquiry scheme based on the alliance chain plays a key role in the medical ecological system, achieves multiple targets of medical data privacy protection, data safety transmission and intelligent medical decision support, and brings important benefits and opportunities to patients, hospitals and drugstores.
