The first electronic device 101 and the second electronic device 102 are used as nodes to establish a block chain and perform data sharing, wherein data can be transmitted among the first electronic device 101, the second electronic device 102 and the third electronic device 103. The first electronic device 101 and the second electronic device 102 may be installed in a hospital, a pharmacy, or an associated medical facility. Medical institutions to which the electronic devices in the blockchain belong can share medical data. Here, only the first electronic device 101 and the second electronic device 102 are taken as an example, and there may be more nodes in the block chain. The blockchain here may be a federation blockchain, just for the healthcare facility.
The first electronic device 101 and the second electronic device 102 may be electronic devices such as a desktop computer and a tablet computer, where the first electronic device 101 and the second electronic device 102 are all integrated devices.
In the application scenario provided in the embodiment of the present application, the first electronic device 101 and the second electronic device 102 both have functions of an integrated device, and only one integrated device may be mounted in each medical institution, so that a plurality of integrated devices may be mounted in one hospital for convenience of use in each department of the hospital.
For example, in the following description, taking the example that the first electronic device 101 and the second electronic device 102 are both located in a hospital, the hospital to which the first electronic device belongs is the first hospital, and the hospital to which the second electronic device belongs is the second hospital. The first electronic device 101 uploads a main index generated based on medical data of a target object to a blockchain, the second electronic device 102 searches a corresponding main index in the blockchain in order to acquire the medical data of the target object, searches a first hospital with the medical data of the target object according to information contained in the main index, and sends a request for sharing the medical data to the first electronic device 101 of the first hospital, and after the main index is verified, if the verification is passed, the first electronic device 101 sends the medical data of the target object to the second electronic device 102, so that doctors of the second hospital can judge diseases according to historical diagnosis information of the target object, and medical data sharing is achieved. After the second hospital finishes diagnosing the target object, the second electronic device 102 generates a main index based on the medical data of the target object after the current diagnosis and uploads the main index to the block chain, so that the target object can acquire the previous medical data when seeing a doctor in another hospital later.
Further, for other patients, it is also possible to diagnose to the first hospital after the diagnosis is performed at the second hospital, and then the first electronic device 101 may send a request for sharing medical data to the second electronic device 102 in the same manner.
Further, fig. 2 shows another specific usage scenario of the medical data sharing method, as shown in fig. 2, a federation blockchain is formed with integrated devices as nodes, where an integrated device may be an integrated device in a setup medical institution, such as the first electronic device 101, the second electronic device 102, and the third electronic device 103 shown in fig. 1, in this way, the integrated devices in a plurality of medical institutions are linked, and a secure network platform for data flow is provided through the federation blockchain network, and the federation blockchain has a strict admission mechanism. The integrated device provides an interface function, and a medical system in a medical institution is connected to the integrated device, for example, a first electronic device in a first hospital can acquire medical data of a target object through an interface service. Wherein the target object may be any one of the patients who have been treated at the first hospital. The first electronic device can generate an electronic medical record and a main index based on the medical data, the main index is uploaded to the alliance block chain, the main index chain is uploaded, and the medical data is only stored in a medical institution creating the medical data. When another medical institution wants to use the medical data of the target object, for example, the second hospital wants to use the medical data of the first hospital, the second electronic device of the second hospital may obtain the main index circulated in the chain through the identity information of the target object, and may send a data query request to the first electronic device when the information of the first hospital and the address information of the first electronic device are obtained through the main index, so as to implement sharing of the medical data.
The interface functions of all integrated devices need to perform identity authentication, and there is also network admission restriction for data transmission between different integrated devices. The integrated equipment is internally provided with alliance block chain nodes and HIS system access standard services, the integrated equipment constructs a trusted encryption environment, if the integrated equipment requests to access the alliance block chain, the equipment hardware code of the integrated equipment is used as an equipment public key and is used as an identifier for requesting to access the existing alliance block chain, after the integrated equipment is accessed to the alliance block chain, a built-in message queue group between the integrated equipment is established, the equipment hardware code of the integrated equipment is also used as an equipment public key and is used as an identifier for requesting to access, and after the integrated equipment is added to the built-in message queue group of the integrated equipment, point-to-point data transmission can be carried out in the group.
At present, medical data sharing mainly depends on an alliance blockchain, the privacy of the medical data is sufficiently guaranteed by using a blockchain technology, but the storage space of a blockchain network is increased too fast due to huge medical data, wherein in order to solve the problem that the storage space of the blockchain network is increased too fast, the most important problem that the privacy of the medical data is ignored by using cloud storage or a centralized network to store the medical data exists in the prior art.
In order to avoid transmitting the medical data to the blockchain when sharing the medical data, the privacy of the blockchain is used for protecting the medical data from being leaked, and under the condition of protecting the privacy of the medical data, the storage space of the blockchain network is prevented from increasing too fast.
