Electronic film security sharing system and method based on block chain

Abstract

The invention discloses an electronic film security sharing system and method based on a block chain, and the system comprises a block chain network, and a plurality of nodes are arranged on the block chain of the block chain network; wherein each node is deployed in each partner hospital and a supervisor to form an alliance chain; the method is deployed at a node of a partner hospital and used for confirming the right of the electronic film; after being encrypted and verified, the electronic film is stored on the block chain; sending an electronic film reading request, reading the storage record after authorization, and decrypting to obtain a corresponding electronic film access address; the method has the advantages that the right of the generated electronic film is confirmed through the block chain, and the problem that due to the fact that the right cannot be confirmed, benefit distribution is irrelevant to a data owner or due to the fact that data sharing control is not strict, data is used in an unauthorized mode is solved; and the constructed alliance chain is utilized to jointly maintain data and solve the problem of accurate tracing of the data, so that partners can use electronic films from other hospital sources trustingly without worrying about data errors or unknown responsibilities.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a system and method for safely sharing electronic films based on block chains. Background technique [0002] Blockchain refers to a reliable database used in digital cryptocurrencies such as Bitcoin. It is a self-referential data structure. Each record is linked in an orderly manner from the back to the front. It is decentralized, open and transparent, and cannot be tampered with. It is recorded by time stamp and easy to trace, so it is widely used in various fields. [0003] As the largest information source of disease symptoms, medical imaging accounts for more than 80% of all clinical medical information data, and is the largest information source of disease syndrome. As medical care enters the era of big data, medical imaging is gradually digitized, and electronic film technology is developing rapidly. However, electronic imaging currently faces two major pr...
