Abstract

The invention discloses a digital identity signing and issuing method and device based on a block chain and a medium. The method comprises the steps of: determining a block chain platform created in advance based on a block chain framework; receiving an identity issuing request; performing hash on the identity information to obtain a first hash value; generating a random number for the identity issuing request, and hashing the random number to obtain a second hash value; generating a symmetric key, and encrypting the identity information and the random number by using the symmetric key; and obtaining the digital identity after signature is carried out through the private key of the issuing node. The digital identity encrypted by the symmetric key is stored in the block chain, so that the user can acquire the identity information anytime and anywhere, and the method is very convenient. Moreover, the symmetric key needs to be obtained through a private key of the symmetric key, thereby guaranteeing that other people cannot steal the symmetric key easily, and guaranteeing the interests of a user. In addition, because the blockchain platform is in distributed storage, data tampering ofa single node does not take effect, and the truth and credibility of data on the blockchain platform are guaranteed.

Description

technical field [0001] This application relates to the field of digital identity, and specifically relates to a block chain-based digital identity issuing method, device and medium. Background technique [0002] With the development of technology, people use digital identities more and more frequently. [0003] However, in the prior art, if it is not being stored, it needs to be input every time it is used, and the process is relatively complicated. However, if it is stored locally, it cannot be used conveniently, and if it is stored in the network, there is a risk of being stolen. Contents of the invention [0004] In order to solve the above problems, this application proposes a blockchain-based digital identity issuance method, including: determining the blockchain platform created in advance based on the blockchain framework; receiving the user node sent, carrying the user node identity An identity issuance request for information; after the identity information is a...
