[0063] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Combine the following Figure 1-Figure 3 The present invention describes an electronic prescription signature method based on blockchain.

[0065] Figure 1 It is a flowchart of the blockchain-based electronic prescription signing method provided in an embodiment of the present invention.

[0066] like Figure 1 As shown, this embodiment provides a blockchain-based electronic prescription signature method, which mainly includes the following steps:

[0067] Step S101, after receiving the electronic prescription uploaded by the doctor, the doctor's identity is obtained and the doctor's identity is verified.

[0068] In a specific implementation process, the electronic prescription is formed by the doctor after he diagnoses the patient and inputs the medical information through a handheld terminal or other terminal device. After receiving the electronic prescription, it is necessary to verify the doctor's identity first to avoid medical disputes caused by uploading by other people. Furthermore, in order to ensure the security of the electronic prescription uploading process, a terminal device can only be bound to or correspond to one doctor. If the electronic prescription is uploaded by the unbound doctor, the upload operation cannot be achieved. The verification of the doctor's identity is achieved through an identity identifier, which is a recognizable identifier given to the doctor. When verifying the doctor's identity, the doctor's identity is determined by reading the identity identifier.

[0069] Step S102, after the verification is passed, obtain the handwritten signature uploaded together with the electronic prescription, authenticate the handwritten signature, and generate authentication information of the handwritten signature.

[0070] Specifically, when uploading an electronic prescription, the doctor's handwritten signature will be uploaded simultaneously. The handwritten signature can be written by the doctor personally on an electronic device. In order to ensure the authenticity of the handwritten signature, the handwritten signature can be authenticated and authentication information of the handwritten signature can be generated to ensure the authenticity of the handwritten signature and that it has not been tampered with.

[0071] Step S103, matching the doctor's private key based on the identity identifier, signing the electronic prescription with the private key, and obtaining an electronic signature of the electronic prescription.

[0072] Specifically, the doctor is assigned a corresponding private key through identity identification. The generation and distribution of the private key should be completed by a trusted third party or security service to ensure the secure transmission and storage of the key, and use the private key to electronically sign the electronic prescription. The doctor's private key is used to verify and confirm the legitimacy of the transaction or data.

[0073] Step S104, the prescription information and signature data of the signed electronic prescription are distributedly stored through a blockchain network, and the signature data includes the electronic signature and the authentication information.

[0074] Specifically, prescription information will be stored in the blockchain network together with signature data, forming an unalterable and traceable data chain. Such a design can not only ensure the authenticity and legality of prescriptions, but also help doctors and patients better understand and use drugs. At the same time, the transparency and traceability of blockchain can increase public trust in the medical industry.

[0075] Signature data is an important basis for verifying the authenticity and non-tampering of prescriptions. When patients or medical institutions need to obtain prescriptions, they can confirm the authenticity and non-tampering of prescriptions by verifying the legitimacy of signature data. If the signature data is consistent with the record in the blockchain network, it means that the prescription is authentic and has not been tampered with.

[0076] By signing the prescription with a private key, we can ensure the authenticity and security of the prescription. The uniqueness and immutability of the private key ensure the legitimacy and credibility of the signature. At the same time, since the signature data is stored in the blockchain network, any tampering will be rejected by other nodes, further enhancing the security of the prescription.

[0077] Therefore, the doctor's use of a private key to sign when issuing an electronic prescription is one of the important steps in the present invention, which ensures the authenticity and security of the prescription and provides more reliable technical support for the medical field.

[0078] In the blockchain-based electronic prescription signature scheme, prescription information and signature data are distributedly stored through the blockchain network.

[0079] When the doctor completes the electronic prescription and signs it, the prescription information and signature data will be uploaded to the blockchain network. The blockchain network is a decentralized distributed network consisting of multiple nodes. Each node stores all the data on the blockchain, including prescription information and signature data. This distributed storage method has the following advantages:

[0080] Data security: Since data is stored in multiple nodes, any data tampering or damage at any single node will not affect the data security of the entire network. This enhances the reliability and fault tolerance of the data.

[0081] Data immutability: Due to the decentralized nature of blockchain, any tampering with the data will be rejected by other nodes. This ensures the immutability of the data, ensuring the authenticity and security of the prescription.

[0082] Data traceability: Since data is stored on multiple nodes, we can trace the source and flow of data. This helps to investigate and solve problems when they arise, and improves the transparency and credibility of the system.

[0083] By storing prescription information and signature data in the blockchain network, we can ensure the authenticity and security of the data and prevent it from being tampered with or forged. At the same time, this distributed storage method also improves the reliability and fault tolerance of the system, providing more reliable technical support for the medical field.

[0084] In the blockchain-based electronic prescription signature scheme, due to the decentralized nature of the blockchain, if the prescription is tampered with, the tampered data will be rejected by other nodes in the network.

[0085] When a prescription is tampered with, the tampered data will be inconsistent with the original record in the blockchain network. When other nodes receive the tampered data, they will confirm the legitimacy of the data by verifying whether the data is consistent with the record in the blockchain network.

[0086] Due to the decentralized nature of blockchain, each node stores all the data on the blockchain. If the tampered data is inconsistent with the original record in the blockchain network, then the data will be rejected by other nodes. This means that the tampered data cannot be verified as legitimate data and therefore cannot be accepted and stored in the blockchain network.

[0087] This mechanism ensures the security of the prescription. Even if someone tries to tamper with the prescription, due to the decentralized nature of the blockchain, the tampered data cannot be accepted and stored by other nodes. This prevents the spread and influence of tampered data and ensures the authenticity and security of the prescription.

[0088] Therefore, the blockchain-based electronic prescription signature scheme can effectively prevent prescriptions from being tampered with and ensure the security of prescriptions by utilizing the decentralized characteristics of blockchain.

[0089] Further, based on the above embodiment, in this embodiment, after receiving the electronic prescription uploaded by the doctor, obtaining the identity information of the doctor, and before verifying the identity information of the doctor, the following steps are included:

[0090] Receiving the certificate images uploaded by the doctor through the terminal, the certificate images including the front and back images of the identity card and professional qualification certificate;

[0091] Extracting certificate information from the certificate image;

[0092] Comparing the certificate information with information in a preset authoritative database;

[0093] If the certificate information is consistent with the information in the preset authoritative database, the identity identification is issued to the doctor;

[0094] If the certificate information is inconsistent with the information in the preset authoritative database, a verification failure instruction and the reason for the verification failure are returned.

[0095] Specifically, before a doctor issues an electronic prescription, the doctor needs to download an official mobile app and complete the relevant identity authentication process through this app.

[0096] Doctors use the ID card and professional qualification certificate collection function of the mobile app to take photos of the front and back of the ID card and professional qualification certificate. The app uses OCR (optical character recognition) technology to automatically extract information from relevant documents. In order to ensure the accuracy of the information, the app also provides manual proofreading and modification functions. After collecting the relevant information, the extracted ID card and professional qualification certificate information will be sent to the backend server. The backend server connects with the national certification authority in real time to verify the authenticity of this information. This includes checking whether the ID card exists and is valid, and whether the professional qualification certificate is authentic and expired. If the information on the ID card and professional qualification certificate is consistent with the records in the authoritative database, the doctor will receive a notification of successful real-name authentication and can continue to issue electronic prescriptions. If the verification fails, the doctor will be prompted to re-enter or upload the relevant information and be informed of the reason for the failure. All real-name authentication processes and results will be recorded in the log for subsequent review and tracking. Throughout the process, all data transmission is encrypted to ensure the security of data during transmission. The original images of the ID card and professional qualification certificate will only be stored briefly on the server to complete the verification process, and will be immediately deleted or anonymized.

[0097] After completing the real-name authentication, doctors will receive a unique ID that is associated with their ID card and qualification certificate information. In the subsequent electronic prescription signing process, the system will use this ID to confirm the doctor's identity, ensuring that only certified doctors can perform operations such as prescribing and signing prescriptions.

[0098] In this way, we can ensure the legitimacy and authority of electronic prescription signatures and prevent forgery or impersonation of doctors to sign. This further enhances the security and credibility of electronic prescriptions and provides more reliable technical support for the medical field.

[0099] Further, based on the above embodiment, the step of obtaining the handwritten signature uploaded together with the electronic prescription, authenticating the handwritten signature, and generating authentication information of the handwritten signature in this embodiment includes:

[0100] Perform CA authentication on the handwritten signature to generate the authentication information of the handwritten signature.

[0101] Specifically, after the handwritten signature is completed, the doctor needs to upload the signature data to the blockchain network. During the upload process, the system will perform CA (Certificate Authority) authentication on the signature data. CA authentication is a digital certificate authentication method used to verify the legitimacy and authenticity of digital certificates. Through CA authentication, the authenticity and non-tampering of the signature data can be ensured.

[0102] Further, based on the above embodiment, the electronic prescription is signed by the private key and the handwritten signature, and the prescription information and signature data of the signed electronic prescription are distributedly stored through the blockchain network, and further includes:

[0103] Generate a prescription ID of the electronic prescription and prescription information of the electronic prescription, and store the prescription ID and the prescription information in the blockchain network;

[0104] The prescription information includes at least one of the following information:

[0105] Basic information of doctors and patients:

[0106] Name of doctor and hospital where he / she practices;

[0107] Patient's name, gender, age, and ID number;

[0108] Patient visit records and medical history information;

[0109] Prescription basic information:

[0110] Date and time of prescription;

[0111] Diagnosis and condition overview;

[0112] Purpose of prescription and reason for medication;

[0113] the expected effects and possible risks of the drug;

[0114] Prescription drugs and dosage:

[0115] The name, dosage form, strength, and quantity of each drug listed in the prescription;

[0116] Route of administration;

[0117] Drug usage;

[0118] Drug dosage.

[0119] Specifically, when a doctor issues an electronic prescription, he needs to sign the prescription with his private key. The doctor's private key is used to verify and confirm the legitimacy of the transaction or data.

[0120] When a doctor issues an electronic prescription, not only is a unique prescription ID generated, but basic information related to the prescription is also collected and recorded, including but not limited to:

[0121] Basic information of doctors and patients:

[0122] Name of doctor and hospital where he / she practices;

[0123] Basic information of the patient, including name, gender, age, ID number, etc.

[0124] Patient visit records and medical history information (if any);

[0125] Prescription basic information:

[0126] Date and time of prescription;

[0127] Diagnosis and condition overview;

[0128] Purpose of prescription and reason for medication;

[0129] the expected effects and possible risks of the drug;

[0130] Prescription drugs and dosage:

[0131] The name, dosage form, strength, and quantity of each drug listed in the prescription;

[0132] Route of administration (e.g. oral, topical, injection, etc.);

[0133] Usage (e.g. once a day, after meals, etc.);

[0134] Dosage (e.g. how many tablets each time, how many milliliters, etc.);

[0135] This information will be stored in the blockchain network together with the signature data, forming an unalterable and traceable data chain. Such a design can not only ensure the authenticity and legality of the prescription, but also help doctors and patients better understand and use drugs. At the same time, through the transparency and traceability of the blockchain, the public's trust in the medical industry can be increased.

[0136] Further, based on the above embodiment, the method in this embodiment also includes:

[0137] receiving a request for modification of an electronic prescription and receiving a modified electronic prescription;

[0138] Extract whether the signature information of the modified electronic prescription is consistent with the signature information of the electronic signature stored in the blockchain network;

[0139] If they are consistent, the modification of the electronic prescription is agreed, and the modified electronic prescription is stored in the blockchain network;

[0140] If there is any inconsistency, the electronic prescription modification request will be rejected.

[0141] Specifically, in order to ensure the authenticity and non-tamperability of electronic prescriptions, it is not allowed to modify the original electronic prescriptions. However, in actual applications, due to adjustments in the doctor's diagnosis or changes in the condition, the electronic prescriptions need to be modified. Therefore, under the above requirements, when the original electronic prescription is modified, it is modified in the form of a version update, that is, the original electronic prescription stored in the blockchain network remains unchanged, and the modified electronic prescription is saved in the form of a new version. At the same time, when the electronic prescription is retrieved, it is first determined whether there is a modification. If the electronic prescription has been modified, the latest version of the electronic prescription is retrieved. The above measures not only ensure that the electronic prescription cannot be tampered with, but also meet the needs of modifying the electronic prescription in actual situations. At the same time, when the electronic prescription is modified, the original electronic prescription remains unchanged, and the modified electronic prescription is also stored in the blockchain. By checking different versions of electronic prescriptions, it can be further ensured that the electronic prescription has not been tampered with.

[0142] Further, based on the above embodiment, the method in this embodiment also includes:

[0143] Upon receiving an electronic prescription acquisition request sent by a patient or a medical institution, the electronic prescription is issued to the patient or the medical institution, and the blockchain record carried by the issued electronic prescription is obtained;

[0144] Extracting the authentication information and the electronic signature from the blockchain record;

[0145] Determine whether the CA authentication information and electronic signature in the signature data are consistent with the authentication information and electronic signature stored in the blockchain network;

[0146] If yes, the electronic prescription has not been tampered with, and the electronic prescription issuance process is completed;

[0147] If not, an electronic prescription tampering warning message is sent.

[0148] Specifically, when patients or medical institutions need to obtain electronic prescriptions, they need to confirm the authenticity and non-tampering of the prescription by verifying the legitimacy of the signature data.

[0149] When patients or medical institutions obtain prescriptions, they first receive blockchain records containing prescription information and signature data. Then, they need to use corresponding verification tools or systems to verify the legitimacy of the signature data. The process of verifying signature data usually includes the following steps:

[0150] Extract signature data: Extract signature data from the received blockchain record.

[0151] Compare with the records in the blockchain network: Compare the extracted signature data with the records in the blockchain network. This can be done by querying the corresponding block in the blockchain network.

[0152] Verify the legitimacy of the signature data: If the extracted signature data is consistent with the record in the blockchain network, it means that the signature data is legitimate. This further proves the authenticity of the prescription and that it has not been tampered with.

[0153] By verifying the legitimacy of the signature data, patients or medical institutions can be confident that the electronic prescriptions they obtain are authentic and have not been tampered with. This provides an important trust foundation for the medical process and ensures the accuracy and security of medical decisions.

[0154] Therefore, in the blockchain-based electronic prescription signature scheme, it is a crucial step for patients or medical institutions to verify the legitimacy of the signature data when obtaining prescriptions. It ensures the authenticity and security of the prescription and provides more reliable technical support for the medical field.

[0155] By comprehensively judging whether the authentication information of the handwritten signature and the electronic signature are correct, the electronic signature can be guaranteed to be tamper-proof and authentic to the greatest extent.

[0156] By introducing handwritten signatures and CA authentication, we can further improve the security and credibility of electronic prescription signatures. Handwritten signatures can prevent electronic devices from being tampered with or forged, while CA authentication can verify the legitimacy and authenticity of signatures and doctor identity information. These measures together ensure the authenticity and security of electronic prescriptions and provide more reliable technical support for the medical field.

[0157] Further, based on the above embodiment, the method in this embodiment also includes:

[0158] When the doctor signs an electronic prescription for the first time or receives a private key update request from the doctor, a new private key is issued and bound to the doctor's identity.

[0159] In summary, the present invention has the following beneficial effects compared with the prior art:

[0160] Improve medical efficiency: Electronic prescription signatures can reduce the use of paper prescriptions, reduce medical costs, and improve the efficiency of medical processes.

[0161] Enhanced data security: The distributed storage and immutability of blockchain technology ensure the authenticity and security of prescription information, preventing data from being tampered with or forged.

[0162] Improve patient trust: Patients or medical institutions can verify the legitimacy of signature data to confirm the authenticity and non-tampering of the prescription, thereby increasing trust in the medical process.

[0163] Promoting medical information sharing and interoperability: Blockchain-based electronic prescription signature solutions can promote the sharing and interoperability of medical information and improve the overall efficiency of the medical system.

[0164] Reduce the risk of medical disputes: Since the authenticity and safety of prescriptions are guaranteed, the risk of medical disputes caused by prescription tampering or forgery can be reduced.

[0165] Promote digital transformation of the medical industry: Provide a reliable digital transformation solution for the medical industry to promote the medical industry to develop in a more efficient, secure and transparent direction.
