Medical electronic contract evidence storage method based on block chain technology

Abstract

The invention relates to a medical electronic contract evidence storage method based on a blockchain technology, and the method comprises the steps of sequentially carrying out the editing and fillingof an electronic contract through a medical institution, a distributor and a medicine and medical equipment manufacturer when the electronic contract is built, carrying out the digital signature andelectronic signature through a national cryptography SM2 algorithm, and after all parties sign the electronic contract, uploading the electronic contract to a block chain; and when an authentication demand subsequently exists, calculating a hash value through a national cryptography SM3 algorithm, and comparing the hash value with a pre-stored hash value to confirm whether tampering occurs or not.According to the invention, mutual trust of all parties, contract tampering prevention and credible preservation of data in the medical insurance purchasing process can be ensured, supervision in themedical insurance purchasing process is enhanced, autonomous controllability in the medical insurance purchasing block chain security encryption process is realized, and meanwhile, the problems of paper waste and high operation cost of a traditional medical insurance paper contract can be avoided.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for depositing certificates of medical electronic contracts based on block chain technology. Background technique [0002] In the medical insurance procurement process, multiple participants such as medical insurance bureaus, medical institutions, distributors, and manufacturers are involved, and it is necessary to confirm product information, specifications, purchase prices, purchase quantities and other information in the form of contracts. Traditional paper contract signing process , there are the following problems: paper contracts waste paper and high operating costs; traditional paper contracts need to be mailed back and forth by multiple parties, and the time cost is high; traditional paper contracts must use paper as the medium, and storage consumes space; Appraisal is still to verify the authenticity of the official seal. In addition to consuming a lot of t...

Problems solved by technology

[0002] In the medical insurance procurement process, multiple participants such as medical insurance bureaus, medical institutions, distributors, and manufacturers are involved, and it is necessary to confirm product information, specifications, purchase prices, purchase quantities and other information in the form of contracts. Traditional paper contract signing process , there are the following problems: paper contracts waste paper and high operating costs; traditional paper contracts need to be mailed back and forth by multiple parties, and the time cost is high; traditional paper contracts must use paper as the medium, and storage consumes space; Appraisal or appraisal of the authenticity of the official seal, in addition to consuming a lot of time and economic costs, the results are uncertain

Different from traditional paper contracts, it has the advantages of environmental protection, portability, and high efficiency, but at the same time, it has the following problems: there is the possibility of tampering, and the authenticity of the content cannot be guaranteed; when medical institutions, distributors, and manufacturers have disputes, it is difficult to Verifying the authenticity of electronic contracts requires high legal costs and cannot effectively protect the legitimate rights and interests of participants; the Medical Insurance Bureau cannot effectively supervise the entire process of contracting and purchasing
