The invention provides an
industrial Internet identifier distribution and
data management method based on a block chain. A mechanism for carrying out uplink
authentication on enterprise qualificationis added in an identifier allocation process based on a block chain so as to verify whether an enterprise has admission qualification or not; meanwhile, industry affiliation of the enterprise is judged, enterprises in the same industry are classified into the same
local domain, the enterprises completing qualification
authentication can obtain allocated identifier prefixes; And meanwhile, the
system writes abstract information containing contents such as enterprise IDs, enterprise prefixes, enterprise public keys and operation authorities into the block chain, so that the
data security is enhanced. According to the
data management method, an enterprise authority
verification function is added, a public key and operation authority information of a user are obtained from a block chain, signature
verification is carried out on encrypted information of
data management operation initiated by the user, and whether current operation can be carried out or not is judged according to user authority; in the identifier analysis process, the
system ensures that the key data are not illegally tampered by comparing the mapping information stored in the
blockchain.
