Specific embodiment
As shown in Figure 1, the present embodiment is a kind of Immovable Property Registration book management method based on block chain technology, specifically include
Following steps:
User is logged in by user's registration in request end and completes digital certificate generation, and initiates Immovable Property Registration book message tube
Reason request.Digital certificate is the legitimacy in order to prove Immovable Property Registration book information.The method of proof is exactly in request end to number
Word certificate authority application portion authenticates the digital certificate of its identity.
Server-side obtains the digital certificate of Client-initiated Immovable Property Registration book information management request and user.
Using block chain common recognition mechanism, Immovable Property Registration book information and digital certificate are broadcast to the specific of block chain network
Node；
Block chain network node passes through the legitimacy of digital certificate authentication user.The node of server-side receive it is motionless
When producing register information, both sides, which provide mutually the digital certificate that CA mechanism issues, can be completed information checking, and guarantee
The specific node of identity information server-side discloses.
After user be verified it is legal after, block chain network node complete Immovable Property Registration book information endorsement, and sign can
Believe digital signature.Digital signature can not be distorted to guarantee Immovable Property Registration book information in the entire system.Digital signature makes
With asymmetry encryption technology, it can guarantee authenticity and integrality of the Immovable Property Registration book information in transmission process, simultaneously
