Public key coding method and system for block chain

Abstract

The invention provides a public key coding method and system for a block chain. According to the public key coding method for the block chain, a current examination item doctor node encrypts a physical examination report recording a current examination item result of a physical examinee by using a public key of a physical examinee node to form a current physical examination report ciphertext, andstores the physical examination report ciphertext in the block chain. On one hand, the safety of the physical examination report content of the physical examinee is guaranteed by adopting a block chain technology; and on the other hand, due to the adoption of an asymmetric encryption mode, the physical examination report ciphertext can only be decrypted by the physical examinee node through the private key of the physical examinee node, and no other people can know the physical examination result in the whole physical examination process, so that the health privacy of the physical examinee iswell protected.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a public key encoding method and system for block chains. Background technique [0002] A blockchain is a decentralized or at least partially decentralized data structure for storing transactions, and a blockchain network manages, updates and maintains one or more blockchains by broadcasting, verifying and confirming transactions, etc. A network of compute nodes. As described above, the blockchain network may be provided as a public blockchain network, a private blockchain network, or a consortium blockchain network.

Problems solved by technology

[0003] In daily life, people often need to go to the hospital for various physical examination items. Some hospitals do not have the inspection equipment corresponding to some physical examination items, so the examiners need to go to other hospitals for physical examination. The repeated travel process is very inconvenient.

Moreover, during the physical examination process, doctors who have passed various examinations often fill in the same physical examination form. During the physical examination, the contents of various examination reports of the examiners may be seen by various doctors and other physical examiners around. The privacy of the examination report Difficult to guarantee, and inspection report data may be tampered with by others
