[0002] Traditional hospital electronic medical record systems have many problems, such as data being easily tampered with, data stored in centralized databases presenting security risks, and insufficient privacy protection for patient data. The emerging blockchain has the characteristics of decentralization, collective maintenance, and high transparency. Through the application of blockchain technology, data can be shared with other institutions and applied in many aspects. As blockchain technology matures, it can be applied to many fields.

[0003] Therefore, it is an urgent problem for technical personnel in this field to propose a blockchain-based hospital electronic medical record security storage system to solve the problems existing in the prior art. Summary of the invention

[0009] The user registers an account through the user terminal and adds corresponding identity information, and the obtained user information is stored in the storage module. The internal data of the storage module uses the encryption module to generate a unique user ID, and the user ID is uploaded to the first server through the signal module.

[0011] The doctor of the first server associates the user's medical record with the user ID through the doctor terminal, and transmits it to the first server through the signal module as the first medical record information;

[0012] The doctor terminal corresponding to the second server applies for the medical record information and medical record writing authority corresponding to the user ID through the signal module. The second server sends an authorization code to the doctor terminal. The doctor terminal fills in the authorization code in the decryption module so that the first server opens the medical record viewing authority to the doctor terminal of the second server. The doctor terminal of the second server generates the second medical record information and associates it with the user ID, and then transmits it to the second server through the signal module.

[0013] In the above system, optionally, the user terminal input information includes gender, age, hobbies, work, eating habits, work and rest time, and emergency contact information.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0020] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "comprise one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0021] Reference Figure 1 As shown, the present invention discloses a blockchain-based hospital electronic medical record security storage system, including multiple servers, user terminals, and doctor terminals. The user terminals and doctor terminals are respectively connected to the server signals, and each server corresponds to a hospital.

[0022] Specifically, the system is built using the Hyperledger Fabric framework and uses the SDK officially provided by Fabric for communication.

[0023] Further, see Figure 2 As shown, the server has a signal module, a data analysis module, a data storage module, an encryption module and a decryption module inside. The output end of the signal module is connected to the input end of the data analysis module, the first output end of the data analysis module is connected to the first input end of the data storage module, the second output end of the data analysis module is connected to the encryption module and the second input end of the data storage module in sequence, and the output end of the data storage module is connected to the decryption module and the input end of the signal module in sequence.

[0024] Specifically, the server uses the Spring-Data-JPA framework for interaction, and the internal signals include query requests and storage requests.

[0025] Further, the user terminal includes a storage module, an encryption module, a signal module and a display module, the storage module, the encryption module and the signal module are connected in sequence, and the display module is signal-connected to the storage module;

[0026] The user registers an account through the user terminal and adds corresponding identity information, and the obtained user information is stored in the storage module. The internal data of the storage module uses the encryption module to generate a unique user ID, and the user ID is uploaded to the first server through the signal module.

[0027] Further, the doctor terminal includes a signal module, a decryption module, a user management module and a display module, the signal module, the decryption module and the user management module are connected in sequence, and the display module is signal-connected to the user management module;

[0028] The doctor of the first server associates the user's medical record with the user ID through the doctor terminal, and transmits it to the first server through the signal module as the first medical record information;

[0029] The doctor terminal corresponding to the second server applies for the medical record information and medical record writing authority corresponding to the user ID through the signal module. The second server sends an authorization code to the doctor terminal. The doctor terminal fills in the authorization code in the decryption module so that the first server opens the medical record viewing authority to the doctor terminal of the second server. The doctor terminal of the second server generates the second medical record information and associates it with the user ID, and then transmits it to the second server through the signal module.

[0030] Furthermore, the user terminal can authorize the doctor terminal to view the medical record information. The doctor can add medical record information for the user, input it into the server, encrypt the data using the AES encryption algorithm, and store the address information, AES encryption key, user ID, and timestamp returned by the module to form a ciphertext index data structure. The user's AES key is then stored in the blockchain database to achieve secure storage of the user's medical electronic medical records. In the function of applying to view medical records, the doctor can query the list of medical record index records under the patient according to the registered patient ID information. After entering the authorization code, the system can query the re-encryption result of the index agent through the authorization code, and use the result to decrypt the index information. The index is obtained and decrypted, and the doctor terminal of this server cannot modify the medical record information of other server terminals.

[0031] Furthermore, the user terminal input information includes gender, age, hobbies, work, eating habits, work and rest time, and emergency contact information.

[0032] Furthermore, when a user ID corresponds to multiple medical records, the display module generates a number axis and the medical records are displayed in chronological order.

[0033] Furthermore, when the user terminal queries medical record information, it is displayed according to examination subjects and timelines.

[0034] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can refer to each other, and each embodiment focuses on the differences from other embodiments.
