Problems solved by technology

However, due to information barriers between hospitals, information sharing of medical images is only carried out within the hospital; in addition, patients are passive information output during the treatment process, and cannot control the right to share medical images involving their own privacy. There is a serious information asymmetry

Embodiment 1

[0088] A credit mechanism-based intelligent contract medical image security sharing method, comprising the following steps:

[0089] 1) Establish a basic network: Based on the P2P connection method, build a blockchain network for the safe sharing of medical images in medical institutions;

[0090] 2) Set up network nodes: establish medical institution nodes, government regulatory department nodes, and patient nodes of medical image sharing authorization institutions on the blockchain network; medical institution nodes are responsible for image management operations on medical images; government regulatory department nodes are responsible for medical image sharing. The image management operation of the institutional node is supervised and filed; the patient node is used to approve the operation of the medical institution node to manage the patient's personal medical image;

[0091] 3) Data sharing between nodes: medical institution nodes and patient nodes, through the smart con...

Embodiment 2

[0093] Repeat embodiment 1, only in step 3), the shared data operation of each node through the smart contract includes the following steps:

[0094] a The medical institution node sends a data operation request to the smart contract in the blockchain;

[0095] b The smart contract judges the type of shared data operation to be performed by the requesting node through the node operation judgment unit; the type of shared data operation includes: query image, add image, modify image, delete image;

[0096] The c smart contract publishes the data block containing the data operation request to the blockchain network through the node operation execution unit. The data block contains the patient node ID, which must be authorized by the patient node in the designated network, and the medical institution node Only then can the image be operated; if the patient node’s approval agrees to the authorization, the medical institution node completes the requested shared data operation in the...

Embodiment 3

[0101] Embodiment 2 is repeated, except that in step 2), the medical institution node is responsible for performing image management operations on medical images, specifically: the medical institution node is responsible for storing medical images and executing shared data operations on medical images.

Abstract

The invention discloses a safe sharing method of an intelligent contract medical image based on a credit mechanism. The method comprises the following steps: 1), establishing a basic network: establishing a shared network based on blockchain technology through using an intelligent contract as an underlying application; 2), establishing network nodes: setting up independent nodes for the governmentdepartments, medical institutions, and patients in the blockchain shared network; 3), performing data sharing between nodes: enabling a government department to monitor the medical image sharing in real time through the blockchain network nodes, enabling a medical institution node to be responsible for the management and operation of the medical image as the main management node, and enabling a patient node to actively manage the sharing and data operation of the medical image. The purpose of the present invention is to break the information barrier between medical institutions, enhance the initiative of patients during the treatment, protect the privacy of patients during the sharing process, and protect and utilize medical resources through the characteristics of the blockchain networktechnology and intelligent contracts, which is conducive to the development of medical care.

Description

technical field [0001] The invention relates to a method based on smart contracts applied to medical image sharing scenarios, in particular to a credit mechanism-based smart contract medical image security sharing method, which belongs to the field of smart contract applications. Background technique [0002] Due to the continuous popularization and progress of medical imaging technology, computer technology and network technology, medical images have achieved large-scale electronic storage, forming an electronic data resource. In order to uniformly store and manage the informatization data of different medical imaging equipment, various medical institutions use Picture Archiving and Communication Systems (PACS for short) to transfer massive Medical images (including images produced by MRI, CT, ultrasound, various X-ray machines, various infrared instruments, microscopes and other equipment) are stored digitally, and when doctors need them, they are like housekeepers. Quick...
