In the present embodiment, checking node sends described deposit by confirming the flow transferred accounts based on intelligent contract and demonstrate,proves true
Recognize.
First private key is stored on checking node 2, not known to any other node.Thus, it is possible to ensure the first numeral
Signature represents that checking node 2 deposits the confirmation of the summary of card data for really power.Because really power deposits the summary for demonstrate,proving data and really power is deposited
It is one-to-one relation in itself to demonstrate,prove data, therefore, and the first digital signature can represent that checking node 2 deposits card data for really power
Confirmation.
Step S600, requesting node 1 confirm that generation corresponding second deposits card information and is uploaded to and deposits card in response to the card of depositing
Server, wherein, described second, which deposits card information, includes the true power and deposits card data, the true power depositing the summary and the of card data
Two digital signature and the second public key, second digital signature are that true power deposits numeral label of the summary of card data based on the second private key
Name, the second private key and the second public key correspondence.
Digital signature is that acquisition is encrypted in the summary for depositing card data to really power by the corresponding private key of node.The number of node
Word signature can be by the public key decryptions corresponding to node private key.It may be used to indicate that the node for possessing private key for signing
Information confirmation.Card information is deposited accordingly, for first, anyone will can be obtained by first the first digital signature of public key decryptions
The data taken with really power deposit card data summary be compared, if it does, then can confirm that first deposit card information represent checking
Node 2 deposits the confirmation of card data for really power.Similar, card information is deposited for second, anyone can pass through the second public key solution
The summary that the data that close second digital signature is obtained deposit card data with really power is compared, if it does, then can confirm that second
Deposit card information and represent that requesting node 1 deposits the confirmation of card data for requesting node 1 for really power.Second deposit card information in also include
Really power deposits card data.It may be the larger files such as audio, video, picture because really power deposits card data, pass through deposit server 3
It is negative without being constituted to block chain network rather than block chain network is preserved to it, it is possible to achieve the storage of mass file
Influence.
Thus, card information and second is deposited to the upload of deposit server 3 first respectively in checking node 2 and requesting node 1 to deposit
Demonstrate,prove after information, the really power that is stored with deposit server 3 deposits card data, really weigh the summary for depositing card data, checking node 2 true for this
Power deposits the digital signature (the first digital signature) and the public key (first for being verified to the digital signature of the summary of card data
Public key) and requesting node 1 for this it is true power deposit card data summary digital signature (the second digital signature) and for this
The public key (the second digital signature) that digital signature is verified.When above- mentioned information is mutually matched, it can prove that really power deposits card
The authenticity of data obtains the confirmation of checking node 2, and via requesting node 1 and checking node 2 by mutual consent to the confirmation
Carry out depositing card.
Thus, from step S200 to step S600, by verify node 2 true power deposit card data verification it is true after by pre-
The outer trading channel of chain first set up initiates a requesting node 1 transferring accounts to checking node 2.Requesting node 1 is receiving checking
After the bill information of node 2, card request is deposited in generation, is sent in the form of transferring accounts.Checking node 2 receive deposit card request after,
The Hash (namely mark of bill information) of the summary and bill information of depositing card data according to wherein embedded power really judges that this is true
Power deposit card data whether it is preceding be identified it is true, if it is, card is deposited to deposit server signature, while being transferred accounts with confirmation
Form deposits card confirmation to send.Requesting node 1 receive deposit card confirm after also to deposit server signature deposit card.Thus, exist
Requesting node 1 is realized outside chain and verifies that the both sides of node 2 deposit card data for really power and weigh and deposit really card.It is any one in both sides
Side's data that all really power is deposited after card are distorted, and can not also deny preceding affirming conduct.Simultaneously as the first digital signature and
Second digital signature is the signature for the summary that card data are deposited for really power, and generates the first private key and the second private key that signature is used
It is unknowable for deposit server 3.Therefore, card data are deposited and its are plucked even if having distorted true power in the side of deposit server 3
Will, but can be found in follow-up verified so that fraud is difficult to success.
By being communicated to connect outside chain, step S200 to step S600 can be carried out repeatedly, until upper chain condition is triggered.
When communication connection is trading channel outside the High Frequency Link of the present embodiment outside chain, sea can be carried out between requesting node 1 and checking node 2
Amount data are weighed really deposits card operation.
Step S700, upper chain condition triggering after, requesting node 1 or checking node 2 by block chain network to locking
The non-cost output of block chain is settled accounts, and total summary info is uploaded into block chain network with clearing.Total summary info is
To all non-cochains between requesting node and checking node, really power deposits the summary that the corresponding digest calculations of card data are obtained.
In the present embodiment, upper chain condition is that the outer trading channel of chain is closed.Requesting node 1 and checking node 2 can be sent out
Play the outer trading channel of chain to close, that is to say, that both of which can trigger clearing, so as to trigger chain condition.
Fig. 3 is that the embodiment of the present invention weighs the relation schematic diagram for depositing card data and total summary info really.As shown in figure 3, with
Really power deposits card data for exemplified by transaction data.Each deposit card request and both correspond to a transaction.For transaction 1, transaction data and
It is X1 that the area that transaction satellite information is constituted deposits card data entirely, and its corresponding summary is Hash1.Hash1 can deposit card number with really power
Uniquely corresponded to according to X1.For transaction 2, transaction data and transaction satellite information constitute power really and deposit card data for X2, and its is corresponding
Make a summary as Hash2.Hash2 is uniquely corresponding with depositing card data X2.By that analogy, for transaction n, transaction data and attached letter of merchandising
It is Xn that breath, which constitutes power really and deposits card data, and its corresponding summary is Hashn.Hashn is uniquely corresponding with depositing card data Xn.Total summary
Information Htotal is then the summary obtained by identical or different digest algorithm to all digest calculations of all n transactions.
The merging data { Hash1, Hash2, Hash3 ..., Hashn } of total summary info Htotal all summaries corresponding with n transactions
Unique correspondence.It follows that it is also unique correspondence that total summary info Htotal and n, which is deposited card data { X1, X2, X3 ..., Xn },
's.All any one deposited in card data are tampered, and can all cause corresponding summary Hashi to change, and then cause total summary
Information Htotal changes.Therefore, by total summary info, it can effectively verify that its corresponding multiple card data of depositing whether there is
Change.Meanwhile, requesting node 1 and either one in checking node 2 are used as the initiator for depositing card request and deposit the reception for demonstrate,proving request
Side, all power really can be got during card is deposited in interaction and deposit card data and its summary.Based on the principle, requesting node 1
It can be settled accounts with checking node 2 as the node of block chain network by block chain of initiation and all of non-cochain are deposited into card number
According to corresponding total summary info as the part of records of block chain Transaction Information in the block of block chain.Base area, can be with
Based on block chain technology, total summary info is calculated using Merkel tree (Merkle Tree).What is calculated by this method is total
Summary info is to include the data for the root node that all non-cochains really weigh the Merkel tree for depositing the corresponding summary of card data.Merkel
Tree is also referred to as Merkel's Hash tree, can be that binary tree can also be that value on multiway tree, leaf node is the cryptographic Hash specified,
The value of non-leaf nodes is to be calculated to obtain according to the value of leaf nodes all downstream.
Center is gone to because block chain has, the characteristics of going to trust, the above-mentioned total summary info recorded in block chain is basic
It can not possibly be tampered.Third party can verify trustship on deposit server 3 by reading total summary info on block chain 4
Really power deposits the confidence level for demonstrate,proving data to correspondence.For example, third party's node is needing to obtain requesting node 1 and is verifying that node 2 is true
Recognize deposit card data when, can from deposit server 3 obtain correspondence really power deposit card data and requesting node 1 upload second
Deposit card information and the checking upload of node 2 first deposits card information, and verifies this by corresponding total summary info on block chain
Deposit whether card data are tampered.Ensure that really power deposits card data by block chain can not also be tampered in itself, so that data deposit card
In data involved by each link can be verified and prevent to distort and forge.
The mass data deposit system of the present embodiment is described by taking a pair of requesting nodes 1 and checking 2 as an example above.
It should be understood that system can accommodate greater number of node carry out both sides' confirmation in point-to-point mode deposit card.For example, system can be with
