BLOCK CHAIN PLATFORM BASED DIGITAL CERTIFICATE ISSUING SYSTEM AND METHOD

摘要

The present invention belongs to the digital certificate information security field and provides a block chain platform based digital certificate issuing system. The entire issuing process of a digital certificate is implemented by a block chain oracle machine server of the system and a smart contract deployed in the block chain; and the related information of the finally issued certificate is stored in the block chain, so that corresponding operations can be subsequently performed on the corresponding certificate in the block chain; thus, by use of the characteristic of the decentralization of the block chain, the digital certificate is recorded and managed by a decentralized block chain platform, the transparency, the auditability and the anti-falsifying performance of the entire issuing process of a digital certificate are improved; and furthermore, safety loopholes caused by the digital certificate issuing process by taking the current certificate issuing body as a center, are avoided.
