Patient family member remote confirmation system and authorization method based on block chain

Abstract

The invention relates to a remote confirmation system for family members of a patient based on a block chain. The system comprises a registration and management platform, a data distributed storage subsystem, a block chain network and a user terminal. The registration and management platform comprises doctors, patients and family members of the patients. The private key is stored in a user terminal by each user and is used for digital signature; wherein the private key of each party is bound with the corresponding identity identification information; the data distributed storage subsystem is used for storing evidence for performing remote signature confirmation in the digital signature process, encrypting a secret key by using a public key based on a family member of a patient, and forming a proof material by the encrypted secret key and encrypted data and uploading the proof material to the data distributed storage subsystem, and recording the remote confirmation conclusion and the hash value of the proving material in the block chain network. The invention also provides a case data patient family member remote authorization query method realized by the system.

Description

technical field [0001] The invention relates to a remote confirmation method for family members in the process of medical treatment. Background technique [0002] During the treatment process, patients will have some decisions that need to be made by their families, such as whether to use a certain treatment plan, whether to use a certain drug, and so on. If the family members are present, they can directly sign for confirmation. However, if the family members are not at the scene, the doctor needs to communicate with the family members through voice or video calls and get the family members' decision. However, since there was no on-site signature, in the case of subsequent medical disputes, the hospital could not produce conclusive evidence to prove the decision of the family members at that time, and the patient could not prove whether the decision at that time was truthfully obtained by the doctor. Although it is also possible to record and save the calls and videos at ...

AI Technical Summary

Problems solved by technology

However, because there is no on-site signature, in the case of subsequent medical disputes, the hospital cannot produce conclusive evidence to prove the decision of the family at that time, and the patient cannot prove whether the decision at that time was truthfully obtained by the doctor

Although it is also possible to record and save the calls and videos at that time, there are still risks of data destruction and forgery, and video and voice data may be used for other purposes, and there is a risk of privacy leakage

In addition, in the remote confirmation scenario, there are uncertainties in the identification of family members and patients and whether the doctor has actually received the confirmation information from family members, which may cause hidden dangers in subsequent medical disputes.
