Description

Technical Field

[0001] The present invention relates to the field of data protection, and in particular to a method for protecting patient privacy of gynecological data. Background Art

[0002] With the continuous development of science and technology, data office has brought convenience to people. However, while science and technology have brought convenient data services to people, there are also certain security risks, especially in terms of patient privacy. Patient data contains a large amount of user sensitive data, such as personal health records, diagnosis records and other data information; therefore, it is increasingly important to protect the privacy of patient data;

[0003] A secure telemedicine data sharing method supporting patient privacy protection is disclosed with publication number CN112966302B. A secure telemedicine data sharing method supporting patient privacy protection is disclosed. The parameter generation center generates system public parameters and system private keys; the hospital server generates identity public keys and first identity private keys for corresponding doctors; the case encryption client generates ciphertext keywords and medical record ciphertexts, and creates indexes based on ciphertext keywords and case ciphertexts, and splices ciphertext keywords, medical record ciphertexts, and indexes into a large file encrypted medical record; the case decryption client generates a trapdoor based on keywords, authentication public keys, the doctor's first identity private key, etc., and decrypts the medical record ciphertext to restore the plaintext case. The embodiment of the present invention applies searchable encryption technology to telemedicine services. Patients can specify one or more doctors to retrieve and decrypt the encrypted medical records locally, which solves the problem of patient privacy leakage in traditional telemedicine services and has strong practicality.

[0004] An online diagnosis system and method for protecting patient privacy and data leakage with publication number CN113470810B discloses an online diagnosis system and method for protecting patient privacy and data leakage, and the system includes a medical user terminal, a medical cloud server and a medical data terminal. The medical user terminal generates a secret share of medical data and initiates a diagnosis request to the cloud server with the medical data share, and obtains the diagnosis result with the assistance of the data terminal after receiving the service response; the medical cloud server completes the medical data preprocessing and calculates the decision function value on the secret share, and returns the decision function share to the user as a service response; the medical data terminal generates a diagnosis model parameter share and sends it to each server, interacting with the user terminal to assist the user in obtaining the diagnosis result. The present invention realizes the privacy protection of user medical data and diagnosis model parameters, and can be used to provide online diagnosis services with privacy protection for medical users.

[0005] However, the current excessive emphasis on privacy protection of gynecological data during the diagnosis process of medical staff may reduce the accuracy of the medical staff's diagnosis process to a certain extent. In addition, all patient gynecological data are encrypted and information sharing within the medical system cannot be achieved. Therefore, how to ensure information sharing between medical staff on the basis of protecting the privacy of patient gynecological data is a problem we need to solve. To this end, a patient privacy protection method for gynecological data is provided. Summary of the invention

[0040] Verify the patient's basic information, and determine whether to generate a corresponding consultation number based on the verification result. By setting the consultation number, the medical account obtains the patient's self-reported information based on the consultation number and diagnoses the patient. In this way, medical staff can obtain the patient's self-reported information based on the consultation number during the gynecological diagnosis of the patient, thereby avoiding contact with the patient's personal privacy, thereby improving the privacy of the patient's corresponding gynecological data;

[0041] By setting up a forward search window and a reverse search window for information retrieval from medical accounts and patient accounts respectively, when medical staff retrieve corresponding gynecological medical data information through the medical account in the forward search window, they cannot obtain the corresponding patient privacy data. When patients retrieve data information corresponding to their patient accounts in the reverse search window through their patient accounts, they only obtain their corresponding gynecological medical data. This enables data sharing for medical staff while ensuring patient privacy. BRIEF DESCRIPTION OF THE DRAWINGS
