Step 2: the processing of multiple party signatures evidence fixed platform will calculate resulting Hash and send to multiple party signatures in step 1
It is handled in evidence fixed platform using multiple party signatures evidence fixed platform, successively includes determining common recognition algorithm, determining block link network
Network, block chain network by Hash be respectively sent to notarial office's node, Arbitration Committee's node, law court's node, at other agency nodes, etc.
To handle in next step；
Step 3: node common recognition, in notarial office's node, Arbitration Committee's node, law court's node, other agency nodes respectively to Kazakhstan
Uncommon progress identity validation, Hash verifying, common recognition processing, signature processing, cochain are fixed.
As a further optimization solution of the present invention, the evidence after a kind of multi-party common recognition signature as described in claim 1
Fixed verification method, it is characterised in that: if the Hash authentication failed at notarial office's node, notarial office's node send Hash to multi-party
Signature evidence fixed platform；If Hash is proved to be successful, notarial office's node carries out common recognition processing；
If knowing together processing failure, notarial office's node send Hash to multiple party signatures evidence fixed platform；It is public if knowing together successfully
Node successively carries out signature processing at card, cochain is fixed, and common recognition instruction is sent at Arbitration Committee's node；
If knowing together processing failure at Arbitration Committee's node, Arbitration Committee's node send Hash fixed flat to multiple party signatures evidence
Platform；If common recognition is handled successfully, signature processing is carried out, common recognition instruction is sent at law court's node after signature processing, and is arbitrating
Cochain is carried out at committee's node to fix；
If knowing together processing failure at law court's node, law court's node send Hash to multiple party signatures evidence fixed platform；If
Common recognition is handled successfully, carries out signature processing, common recognition instruction is sent at other agency nodes after signature processing, and save in law court
Cochain is carried out at point to fix；
If Hash is sent to multiple party signatures evidence and is fixed by the Hash authentication failed at other agency nodes, other agency nodes
Platform；If Hash is proved to be successful, other agency nodes carry out common recognition processing；If knowing together processing failure, other agency nodes will be breathed out
It is uncommon to send to multiple party signatures evidence fixed platform；If knowing together successfully, other agency nodes successively carry out signature processing, cochain is fixed.
The beneficial effects of the present invention are:
It is verified by Hash, ensure that the privacy of data.
It is handled by setting common recognition, ensure that foundation on several nodes of distributed block chain, each node is respectively tieed up
Protect the final consistency of data.
It is fixed by the way that cochain is arranged, ensure that the safety of user data.
By identity validation, verify whether the information provided on block chain is really to request the side's of approval verifying hash.
Detailed description of the invention
Fig. 1 is the flow diagram of the fixed verification method of evidence after the multi-party common recognition signature of one kind of the invention；
Fig. 2 is the flow diagram of Fig. 1 specific embodiment.
Specific embodiment
The application is described in further detail with reference to the accompanying drawing, it is necessary to it is indicated herein to be, implement in detail below
Mode is served only for that the application is further detailed, and should not be understood as the limitation to the application protection scope, the field
Technical staff can make some nonessential modifications and adaptations to the application according to above-mentioned application content.
Embodiment
The fixed verification method of evidence after the multi-party common recognition signature of one kind as shown in Figure 1, includes the following steps,
Step 1: multiple groups original data are respectively adopted Encryption Algorithm processing, calculated encryption by the encryption and Hash calculation of data
Method treated multiple groups original data calculate Hash, calculate resulting Hash and wait and handle in next step；
Step 2: the processing of multiple party signatures evidence fixed platform will calculate resulting Hash and send to multiple party signatures in step 1
It is handled in evidence fixed platform using multiple party signatures evidence fixed platform, successively includes determining common recognition algorithm, determining block link network
Network, block chain network by Hash be respectively sent to notarial office's node, Arbitration Committee's node, law court's node, at other agency nodes, etc.
To handle in next step；
Step 3: the Hash in step 2 is sequentially allocated to notarial office's node, Arbitration Committee's node, law court by node common recognition
Node, other agency nodes；Hash is carried out respectively in notarial office's node, Arbitration Committee's node, law court's node, other agency nodes
Identity validation, Hash verifying, common recognition processing, signature processing, cochain are fixed.
As shown in Fig. 2, including former data A, former data B, former data C, former data D, former data A, former number in the present embodiment
