Abstract

The invention discloses a metering electronic certificate verification management system based on a block chain, and the system comprises the following contents: a system technical scheme: a Bootstrap framework and an HTML5/CSS/JavaScript language are used at the front end of the system, a Django framework based on a Python language is used at the rear end of the system, the block chain is an Ethereum public chain, and a file feature value calculation algorithm is an SHA256 algorithm; the system module comprises a metering electronic certificate verification sub-module, a certificate and seal management sub-module, a signature function sub-module and a background management function sub-module. According to the metering electronic certificate verification management system based on the block chain, data of the metering electronic certificate can be verified and cannot be tampered, the credibility of the metering electronic system is improved, meanwhile, malicious users can be prevented from tampering the metering electronic certificate of the system, and the safety of the metering electronic certificate system is improved.

Description

technical field [0001] The invention belongs to, and in particular relates to a block chain-based metering electronic certificate verification management system. Background technique [0002] The enterprise traditionally deploys the measurement management system on the intranet server for data security, and the external inspection unit cannot access the internal data and certificates, and the existing system certificates are mostly paper versions, which consume a lot during printing and transportation. The authenticity verification of the certificate is also a difficult problem to solve. Metrological verification and calibration certificates are important technical documents for metrological technical institutions to provide external traceability results of quantity values. With the development of digitalization, the electronicization of certificates has become the current and future application trend. Contents of the invention [0003] The purpose of the present inventi...
