The upset price data of the auction users.Wherein, it can specifically include targeted auction object in the upset price data
The ID and upset price of product.
In one embodiment, the first exchange data and second client are obtained in first client
After end obtains the second exchange data, the second exchange data can also be sent to institute by second client
State third client.In this way, after the third client obtains the second exchange data, the subsequent third client
It can be based on the bat of the first exchange data, the second exchange data, the auction users with first client
The bid data of floor data and the second auction user is sold, the second multi-party computations is initiated, obtains whether auction succeeds
Auction result.
S15: the third client and second client initiate the second multi-party computations, obtain auction whether at
The auction result of function；It is upset price data of the auction result based on the auction users, the first exchange data, described
The bid data of second exchange data and the second auction user utilizes second multi-party computations corresponding default the
Two computation models obtain.
In the present embodiment, after the third client obtains the first exchange data, the third client
End and second client can be based on the bats of the first exchange data, the second exchange data, the auction users
The bid data of floor data and the second auction user is sold, the second multi-party computations is initiated, obtains whether auction succeeds
Auction result.Wherein, the auction result can upset price data based on the auction users, the first exchange number
According to, the bid data of the second exchange data and the second auction user, utilize second multi-party computations corresponding
Default second computation model obtain.
Specifically, in practical applications, default second computation model is also possible to the Secure meter being pre-designed
Calculate model.For example, can be handed over by presetting the second computation model described first after initiating the second multi-party computations
It changes data and the second exchange data is decrypted, obtain the bid data of the first auction user.Then,
The bid data of obtained the first auction user to be compared with the upset price data, and by described second
The bid data of auction user and the data of the upset price compare, and obtain comparing result.If described in comparing result
The bid of first auction user and the second auction user are respectively less than the upset price, then can be determined that auction result is
Auction failure.If only having going out for an auction user in the first auction user described in comparing result and the second auction user
Valence is greater than or equal to the upset price, then can be determined that auction result for auction success, can also determine auction user
Bid be auction successful target bid.If the first auction user described in comparing result and the second auction user's goes out
Valence be all larger than or be equal to the upset price, then can be determined that auction result be auction success, can also further will described in
The bid data of first auction user and the bid data of the second auction user compare, can using best bid as
The successful target bid of auction.In this way, in conjunction with multi-party computations (Secure Multi-Party Computation,
SMPC), it is ensured that during auction, the auction data of the privacy and auction users of the bid data of each auction user
Privacy, such as upset price data, so that each user only knows the private data of oneself before determining auction result,
Data without knowing other users can be to avoid the moreover, because entire auction process does not have the participation of third party's auction platform
Tripartite's auction platform exposes the risk of auction data to some auction user, and then the fair public affairs of entire auction process can be improved
Positivity.
In the present embodiment, the calculating process of second multi-party computations can be in the third client or institute
It states and is completed in the second client, can also be completed in above-mentioned server.If completing in above-mentioned server, obtaining calculating knot
After fruit, for example, the auction result can be fed back to described second by the server after obtaining the auction result
Client and the third client.
In one embodiment, in practical applications, if only there are two auction user, it is generally the case that described the
It is described after target when three clients and second client obtain the successful auction result of auction and auction success is bid
Second auction user has known that target is bid, then will know the corresponding auction user of target bid.For example, it is known that
Auction user is not oneself, is exactly an other side.In view of the second auction user may not bid true target
It is sent to the first auction user, for this purpose, can incite somebody to action by second client if the auction result is that auction succeeds
The second exchange data are sent to first client and/or the third client.For example, second client will
The second exchange data are sent to first client and the third client, alternatively, being only sent to one of visitor
Family end.After receiving the second exchange data, first client and/or the third client can be initiated
Third multi-party computations, obtain the successful target bid data of auction and the corresponding target auction of the target bid data is used
Family information.Wherein, the target bid data is based on the first exchange data and the second exchange data, utilizes described the
The corresponding default third computation model of three multi-party computations obtains.
Specifically, the default third computation model is also possible to the multi-party computations model being pre-designed.For example,
It, can be by presetting third computation model, to the first exchange data and described the after initiating third multi-party computations
Two exchange data are decrypted, and obtain the bid data of the first auction user and the bid of the second auction user
Data.Since auction result is auction success, then having one in the bid data of two auction users is target bid data.
Under normal conditions, since successfully be that bid is highest be that target is bid to rule for auction, then, the can be preset by described
Three computation models, using the best bid data in the bid data of two auction users as the target bid data, and can
Using by the corresponding auction user of target bid data as the target auction user.Wherein, the third multi-party computations
Calculating process can be completed in first client or the third client, can also be complete in above-mentioned server
At.If being completed in above-mentioned server, after obtaining calculated result, for example, obtaining the first exchange data and described
After second exchange data, the server can be by the account information of the target bid data and the target auction user
Feed back to first client and/or second client.Finally, first client and/or the third client
The account information of the target bid data and the target auction user can be sent to second client by end.This
Sample, the first auction user and the auction users can obtain true target bid data.Moreover, if second
Auction user will obtain the successful bid data of auction by second client and be sent to first client, can be with
Whether the successful bid data of auction for judging that the second auction user provides is true.So as to ensure auction users and all competing
The account information of true target bid data and target auction user can be obtained by clapping user.
In one embodiment, in practical applications, it is contemplated that the quantity for participating in the auction user of auction may compare
It is more, then for the auction process that multiple auction users participate in, it still can be in conjunction with multi-party computations, using the number of above-mentioned auction
Auction is carried out according to processing method, and obtains auction result.For example, multiple auction users can pass through multiple auction clients respectively
It is common to initiate the first multi-party computations, obtain multiple exchange data.Wherein, the auction client is equivalent to first visitor
Family end or second client.It then can be by an auction client in multiple auction clients by corresponding exchange
Data are sent to auction client.Wherein, the auction client is equivalent to the third client.Obtaining the exchange data
Later, the auction client can initiate the second Secure meter with other auction clients in addition to the auction client
It calculates, obtains auction result.
In one embodiment, in practical applications, after obtaining auction result, if auction result be auction at
Function, auction users and all auction users know the successful target bid of auction and target auction user.At this moment, subsequent
To carry out auction transaction.In order to guarantee to clap the fairness of transaction, it can use block chain (Block Chain) and complete auction transaction
Process.Wherein, block chain is the data structure of distributed storage disclosed in all block chain nodes to access server, includes
Several block (Block).User can access auction bidding system by web terminal or the end app and register and log in, after login,
A block chain node is formed, forms P2P network, block chain number with other block chain nodes of access auction bidding system server
According to that can be stored in P2P network, the paralysis of any one or more block chain nodes of P2P network will not result in block chain data
Loss, such block chain data just have very strong safety, it is ensured that the persistence of data and can not distort.When an area
When block is persisted in block chain data, the block chain data of the block chain node storage of access server can be added to this
Block.Block is singly added in block chain data according to persistence time sequencing, in addition in block chain data
Each block outside first block will be linked to its previous block, and such block chain data are formed a block
This block is linked, just as a chain, as soon as the block can not after a block is persisted to block chain data
It is modified.
Specifically, auction information can be sent to by server by the third client, the auction information is for example
It may include ID, title, description content, picture and the type of items of auction article, and price of starting auction, the third auction are used
Account public key of the family on block chain, the IP address of multi-party computations node and port information etc., thus the server
Auction contract can be generated according to the auction information, and the auction contract is recorded in block chain.At this moment, it is actually answering
In, any one auction is vied for purchase transaction request with can start to send to the server per family by corresponding client,
Auction users can also send auction trade request to the server by corresponding client.Specifically, first visitor
Family end or second client can send transaction request of vying for purchase to the server.Wherein, in the transaction request of vying for purchase
It may include first public key or the second auction user of the first auction user on the block chain respectively in institute
State the second public key on block chain.The third client can send auction trade request to the server.Wherein, described
It may include the target bid data of the target auction user, and the target on the block chain in auction trade request
Public key.Then, the server may determine that it is described vie for purchase transaction request and the auction trade request whether meet default friendship
Easy condition, if satisfied, trading according to the auction contract.
In the present embodiment, it is described vie for purchase transaction request or the auction trade request can be according to preset rules into
The character string that row is write.Wherein, it is logical to can be the network followed between the client and the server for the preset rules
Believe agreement.For example, it is described vie for purchase transaction request or the auction trade request can be the word write according to http protocol
Symbol string.The preset rules can limit vie for purchase transaction request or each component part in auction trade request and each
Putting in order between a component part.
In the present embodiment, in practical applications, the auction process participated in for multiple auction users, is determining auction
After successful target auction user and target auction bid data, it is contemplated that not only target auction user can may initiate to vie for purchase
Transaction request, other auctions user may also can initiate transaction request of vying for purchase, but include in the transaction request of vying for purchase initiated it is competing
The valence of taking might not be identical as target auction bid.In that way it is possible to will lead to the abnormal problem of transaction.For this purpose, with above-mentioned
For two auction users, whether transaction request of vying for purchase described in judgement and auction trade request meet default terms of trade,
It can specifically include, when first public affairs of the first auction user for including in the transaction request of vying for purchase on the block chain
Target Public Key of the target auction user for including in key and auction trade request on the block chain matches, and
When the first transaction value data of the first auction user and the target bid data match, it is possible to determine that described to vie for purchase
Transaction request and auction trade request meet default terms of trade.Alternatively, when the institute for including in the transaction request of vying for purchase
State the second auction user respectively on the block chain the second public key and the auction trade request in include the target
Target Public Key of the auction user on the block chain matches, and the second transaction value data of the second auction user with
When the target bid data matches, it is possible to determine that vie for purchase transaction request and the default friendship of auction trade request satisfaction
Easy condition.
In the present embodiment, it is contemplated that it is possible that auction success, but because target auction user never initiates
It vies for purchase transaction request, and causes auction transaction that can not be normally carried out, and auction users can not restart auction next time
Situation.For this purpose, transaction limits condition can be set for above-mentioned process of exchange.For example, when the exchange hour of the transaction is described
When in default time bracket, it can trade according to the auction contract.
In a concrete application scene, auction users Sally is at auction site for service (Auction Web Server)
Upper registration auction article fills in the recommended information of auction article, price of starting auction, oneself account public key on block chain, safety
