The prescription is a medical document which is issued by a registered doctor for a patient during a diagnosis and treatment activity, is audited, prepared and checked by a medical professional qualified by a medical professional and serves as a certificate for taking a medicine for the patient. The prescription is a written file of the medicine taken by a doctor to a patient, is the basis for preparing the medicine by a pharmacy staff, and has legal, technical and economic responsibilities. Current legal regulations require that a prescription be made by a medical practitioner at a place of practice and signed or stamped by the practitioner. In the case of electronic prescriptions, they must be printed out and signed and sealed by a physician. Therefore, paper-based prescriptions are currently used in the medical field. Electronic prescriptions issued in medical places such as hospitals are mostly stored in HIS systems at hospitals, and the prescriptions cannot realize electronic signature and electronic circulation of doctors approved by countries. If a patient is to purchase a prescription at a pharmacy, the patient is required to provide the corresponding prescription. The prescription must be obtained at the corresponding medical place and is prepared by doctors, and the prescription obtaining cost is high. After a patient holds a prescription and purchases a medicine in a pharmacy, the pharmacy reports all prescription data to units such as a health council, a social security agency and the like regularly. Since purchasing prescription drugs must be done using paper prescriptions, the way to purchase prescription drugs on the internet is essentially infeasible, which is very inconvenient for the patient.
However, the existing electronic prescription data has poor confidentiality and cannot meet the requirement of data encryption, and on the other hand, the existing electronic prescription data cannot perform access authorization aiming at different authorized objects, so that the development of the electronic prescription technology is restricted, and therefore, a new technical means is needed, and on the basis of overcoming the technical problems, a large amount of data redundancy can be avoided.

In this embodiment, after splitting the electronic prescription block chain data into different data fields as needed, a content key for encryption is created for each data, and the content key is divided into a content public key and a content private key. When in encryption, the public key is used for encrypting data (electronic prescription data after the data packet is split, the number of a related data domain and a content private key), then the content private key is secondarily encrypted by using the public key of an object needing authorization, and the encrypted identification of the authorized object and the encrypted data form an authorization data block.
In this embodiment, the prescription data or the prescription increment data need to be verified when written into the blockchain, and the verification is whether the prescription-making parties are real and valid (including hospitals, medical practitioners, doctors, individuals, etc.). When the contents are all truly valid, the data is valid, thereby allowing the write blockchain to be synchronized by all nodes, otherwise the write blockchain is discarded. And this process will be automatically executed and verified by the smart contracts issued on the blockchain. The qualification information includes institution information and personal information, the personal information includes at least physician information, pharmacist information and patient information, the authentication unit can authenticate the qualification information through a fixed digital certificate and a dynamic digital certificate, preferably, in this embodiment, the personal information can be authenticated through the fixed digital certificate, and the institution information can be authenticated through the dynamic digital certificate according to different attributes of the electronic prescription, for example: the organization information is authenticated according to the region and time of the electronic prescription, and the electronic prescription can be issued in a digital certificate mode. The published digital certificates for individual physicians, pharmacists and individuals are downloaded by the authentication server. The authentication system maintains the validity period of the certificate, and the expired certificate automatically closes the download. There are two forms of authentication services for medical institutions, preferably, hospitals and pharmacies issue fixed certificates (the same certificate issuing method as that for doctors and pharmacists), and institutions with higher authority such as drug administration and health administration issue dynamic certificates. The dynamic certificate is generated according to a certain strategy, electronic prescriptions of different types, different regions and different times are authorized by different certificates, the digital certificate can be stored in special hardware or corresponding terminals, and can be kept and used by a doctor, a pharmacist, a medical institution or other roles needing to use the electronic prescription system, and can be deployed in a unit or an institution needing to access the electronic prescription system. When the units create electronic or related data, the data is processed by the access server and uploaded to the electronic prescription system. And when the electronic prescription data is read, the access unit reads the data from the electronic prescription system and verifies the validity, and then returns the verified data and the verification result.
In the embodiment, the first data encryption and the authorization of the object to be authorized are carried out on the electronic prescription by using an asymmetric encryption algorithm, and the encrypted data is written into the nodes of the block chain; and the authorization of the object to be authorized comprises the step of encrypting the private key encrypted for the first time by using the public key of the object to be authorized for the second time.

When a common user purchases a medicine at a pharmacy, a prescription list needs to be displayed to the pharmacy. The user firstly selects a prescription needing to purchase the medicine, a two-dimensional code and a corresponding serial number are created on the APP of the mobile terminal, and after the pharmacy scans the two-dimensional code, the personal mobile terminal and the access unit create a P2P connection for direct communication through requesting the P2P function server. After connection, the personal mobile terminal transmits the prescription data to the access unit, and the pharmacy verifies the prescription and then processes the medicine selling process.
In the embodiment, a reliable, non-falsifiable and convenient-to-circulate prescription management system is created by combining the blockchain technology and the electronic prescription and utilizing the technologies such as cryptography, intelligent contracts, access control, distributed storage, P2P data transmission and the like. The whole-process supervision of prescriptions from prescription to use by a supervision department can be enhanced.
In this embodiment, a doctor can log in the HIS system of a hospital, and after verification, the doctor makes an electronic prescription, adds information such as a signature of the hospital and the doctor, and performs first data encryption on the electronic prescription by using an asymmetric encryption algorithm and authorizes an object to be authorized, and writes the encrypted data into a node of a block chain; and the authorization of the object to be authorized comprises the step of writing the encrypted private key into the block chain by encrypting the encrypted private key for the first time by using the public key of the object to be authorized for the second time.
