Problems solved by technology

[0002] Medical institutions have always been faced with the problem of being unable to safely share data across platforms. On the one hand, the data is scattered, and different medical institutions and different information systems form data fiddles, making it difficult to achieve a unified view centered on residents. At the same time, the data is incomplete, such as high blood pressure The daily health data of reasonable diet, behavioral habits, healthy psychology and other aspects of management and intervention of common chronic patients such as diabetes and high-risk groups have not been digitized, or are scattered in the systems of smart terminals and wearable device manufacturers; On the other hand, due to the long industrial supply chain, from upstream to downstream, data information passes through many links, and it is difficult to invest enough inspection and management power in every link
Lack of regulatory mechanisms such as data security, privacy protection, and data ownership, individuals and data owners are unwilling to actively open and share

Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides a blockchain-based privacy protection method for medical information sharing, including: establishing a medical record index chain, establishing a medical record chain, and the steps of storing and sharing medical information. The blockchain-based medical information sharing privacy protection method of this embodiment specifically includes the following steps:

[0025] (1) Confirm the identity of the medical institution according to the identification materials provided by each medical institution (first-level unit). After the confirmation is successful, the medical institution (branch hospital, and the connected community hospital) becomes a member of the blockchain medical record system. At this time, according to the distribution of submitted identity certification materials, the applicant has the right to read, write, modify / delete the medical record chain, etc. (as shown in Table 1 below).

Embodiment 2

[0037] Such as figure 2 As shown, this embodiment provides a blockchain-based medical information sharing privacy protection device, which can use the method in Embodiment 1 to realize the sharing and storage of patient information among medical institutions. The device specifically includes a block chain generating module, a medical record index chain ID generating unit, a medical information recording unit, a query module,

[0038] The blockchain generation module is used to establish a medical record index chain and establish a medical record chain.

[0039] The medical record index chain ID generating unit is used to establish a medical record index chain ID for each patient, and perform a hash algorithm according to the identity information of each patient to generate a patient ID with a unique identifier, and complete each patient in the medical record index chain. patient registration.

[0040] The medical information recording unit is used to record the medical info...

Abstract

The invention provides a medical information sharing privacy protection method and device based on a block chain, and belongs to the technical field of the communication. The medical information sharing privacy protection method based on the block chain comprises the following steps: establishing a medical record index chain: establishing a medical record index chain ID for each patient, performing Hash algorithm according to the identity information of each patient to generate the patient ID with a unique identifier, thereby accomplishing the registration of each patient in the medical recordindex chain; establishing the medical record chain: recording the medical information of the patient archived by the medical mechanism in one block of the medical record chain, and performing mapping processing on the absolute address of the block and the ID of the patient index chain, and recording the mapping processing record to the block located by the ID of the corresponding patient index chain; performing information Hash algorithm according to the patient identity input by the medical mechanism when the patient seeks the medical advice, and querying the medical information of the patient in the medical record chain according to the patient ID of the generated identifier.

Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a block chain-based privacy protection method and device for sharing medical information. Background technique [0002] Medical institutions have always faced the problem of being unable to safely share data across platforms. On the one hand, the data is scattered, and different medical institutions and different information systems form data fiddles, making it difficult to achieve a unified view centered on residents. At the same time, the data is incomplete, such as high blood pressure. , diabetes and other common chronic patients and high-risk groups such as reasonable diet, behavioral habits, healthy psychology and other aspects of daily health management and intervention data have not been digitized, or are scattered in the systems of smart terminals and wearable device manufacturers; On the other hand, due to the long industrial supply chain, from upstrea...
