Example Embodiment

[0024] The method and system for decentralized management of medical image data based on blockchain of the present invention establishes a system that is jointly maintained by multiple hospitals, can be expanded linearly, and is more secure and regulated through blockchain and distributed file system. Decentralized PACS system, decentralization enables single-point network bandwidth bottlenecks and security issues to be resolved, and the use of blockchain technology ensures the control of data ownership and access rights in the system. Unlimited rights to all data.

[0025] The technical solution of the present invention will be further described below in conjunction with the embodiments and drawings.

[0026] The present invention provides a blockchain-based decentralized management method for medical image data, based on the existing open source software components and blockchain technology, at least including the following steps:

[0027] The data owner uploads the medical image ...

Abstract

The invention relates to a method for medical image data decentralized management based on a block chain. The data owning end uploads the owned medical image data stores the medical image data as an interstellar file system (IPFS) file, the hash value for the medical image data is taken and the link list file in the IPFS is encrypted by using the public key of the data owning end; the data accesscontract uses the private key of the data owning end to decrypt the encrypted link list file in the step according to the smart contract, and when the data use end transmits the data use end public key information and the payment tokens to the data access contract to request for obtaining the medical image data, the data access contract uses the user public key to encrypt the decrypted link list file again to be transmitted to the data use end and also generates the block chain storing the hash address; and the data use end performs decryption operation through the data use end private key toobtain the link list file and retrieves the interstellar file system to obtain the actual medical image data.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a method and equipment for decentralized management of medical image data based on blockchain. Background technique [0002] With the rapid development of big data, the degree of digitization in various fields is also getting higher and higher. PACS (abbreviation for PictureArchiving and Communication Systems, which means image archiving and communication system) system is applied to the system of the imaging department of the hospital. machine, various infrared instruments, microscopes and other equipment) through various interfaces (analog, DICOM, network) to digitally store a large number of images, when needed, it can be quickly recalled under a certain authorization Use, while adding some auxiliary diagnostic management functions. In the current medical system, PACS mainly has two types: local PACS and cloud PACS. The problem with local PACS is that the storage ...
