Specific embodiment

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is described in further detail.

Fig. 1 is a kind of implementation environment schematic diagram of resource management provided in an embodiment of the present invention.Referring to Fig. 1, the implementation ring It include: resource management system 101 and terminal 102 in border.The resource management system 101 may include multiple nodes, each node A server can be corresponded to, multiple node can store an identical block chain, which is made of multiple blocks, often A block is stored with different information, and the block on a block chain is stored sequentially in time.Implement in the present invention In example, each block can store an interaction message during resource transfers and the contract that generates based on the interaction message Characteristic value.The terminal 102 refers to terminal where the user that the resource management system is serviced, for carrying out with resource management system Interaction, thus from the account of the user to other account transferring resources, or the management based on resource management system is in the account Storage resources etc..The resource management system 101 is used to manage the resource in the account of user, and generates during resource transfer Contract stores the information of interactive information and contract to the block on block chain.The account of user refers to and logs in the terminal 102 User associated by account, e.g., Internetbank, wechat change or game account of user etc. can store user in the account Resource, these resources are workable resource when carrying out network trading, for example, currency resource included in the Internetbank of user, Currency resource, the ideal money in game account or digital ticket in card packet for being stored in wechat change etc..

In the embodiment of the present invention, each node configured identical contract template, the contract template refer to ginseng to be determined Several codes, resource management system 101 can generate one according to the interaction message and contract template between account received The contract of hypostazation that is to say and generate one section of code that may operate on block chain, to carry out resource transfers according to contract Process.In order to facilitate the resource for managing each account, one contract column of resource management system 101 or each account maintenance Table.Certainly, in order to guarantee the safety of contract, resource management system 101 can only be generated in contract list new contract or More new information is added in generated contract, and the information in generated contract is forbidden to be modified.

It should be noted that any node in the resource management system 101 determine need to be stored in current block it is defeated When entering information or generating contract, other nodes in the resource management system 101 can obtain the input according to common recognition algorithm Information or contract, and the input information is also stored in current block, and the contract is stored in contract list, so that resource pipe The information stored on whole nodes in reason system 101 is consistent.

Fig. 2 is a kind of flow chart of resource transfers method provided in an embodiment of the present invention, and referring to fig. 2, this method can answer The interactive process of account on the server and terminal in resource management system shown in FIG. 1, comprising the following steps:

201, the first account user orientation server sends resource transfers request, and resource transfers request is for requesting the first account Resource transfers are to target account.

Wherein, the first account refers to the account for any user that the server is serviced, can the unique identification user.The step In rapid, the user can selection target account and resource transfers number at the terminal so that terminal generates resource transfers request, and Resource transfers request is sent to server.It should be noted that quantity and resource of the embodiment of the present invention to target account Transfer number is not specifically limited.

By taking the resource is Internetbank as an example, when detecting the trigger action to option of transferring accounts, terminal can show the boundary that transfers accounts Face may include account communication list and transfer amounts input frame in the interface of transferring accounts, and in turn, the available user of terminal is turning The transfer amounts inputted in account amount of money input frame obtain user selects in account communication list one as resource transfers number A or multiple target accounts.Certainly, transfer amounts can also be respectively set for each target account in user.

In the embodiment of the present invention, resource transfers request also carries Contract ID.Contract ID is used for unique identification first The first resource transfer process that account is initiated is enabled the server to relating to during the resource transfers according to the Contract ID And logout on block chain, avoid malice account and distort or deny the resource shifted, improve resource transfers mistake The non-repudiation of Cheng Zhongyi transferring resource and the reliability of resource transfers.

Under different application scenarios, the Contract ID can using it is different by the way of obtain.For example, in order to guarantee public affairs The safety of resource transfers process under the scene of total block chain, referring to Fig. 3, it is raw that the embodiment of the invention provides a kind of Contract IDs At flow chart, in the product process, terminal can be according to the first account private key, and by elliptic curve, (curve of selection can Think secp256k1) the first account public key is calculated, and Hash calculation, the hash algorithm of use are carried out to the first account public key It can be SHA256 (256,256 hash algorithms of Secure Hash Algorithm) and RIPEMD160 (RACE Integrity Primitives Evaluation Message Digest, 160 raw integrity verification message abstracts are calculated Method) combination, in turn, terminal can encode obtained cryptographic Hash, obtain the Contract ID, and coding mode can be with BASE58 (58 basic codings).Wherein, the first account private key can be a string of the characters generated at random, and digit can be 256 bits.In another example since privately owned block chain has stringent access control, and participating in money under the scene of privately owned block chain The account of source transfer process is the inter-account of a tissue, therefore is not necessarily to consider except interactive side during resource transfers The intervention of malice account, also just without considering the security risk that Contract ID is forged, then the Contract ID can be any word Symbol, e.g., terminal obtains a number by way of digital self-propagation, as the Contract ID.

202, when server receives the resource transfers request of the first account, the first contract is generated, the first contract is used for Indicate the resource transfers condition of the first account.

Wherein, the first contract refers to the code that may operate on block chain.In the step, when server receives the money It, can be based on the every terms of information in configured contract template and resource transfers request, by the items when transfer request of source Information generates first contract as the parameters in contract template.

Specifically, in order to facilitate the contract of each account of server admin, server is one contract of each account maintenance List, thus server can be requested according to resource transfers in the first account, is generated in the contract list of the first account One contract.May include in first contract Contract ID, resource transfers number, target account, the first contract expiration time with And contract generates the information such as time.The expiration time of first contract can be by server according to current time and default time limit And value obtain.It should be noted that server is by first in order to guarantee the number of resources balance during entire resource transfers Resource transfers corresponding with resource transfers number are to first contract in account.

It may include multiple target accounts in resource transfers request, if the first account in actual application scenarios It is provided with resource transfers number for each target account, then server can be when generating the first contract by each target account and its The corresponding storage of corresponding resource transfers number.Alternatively, if the first account is not provided with the corresponding resource transfers of each target account Number, then server resource transfers can be requested when generating the first contract in resource transfers number be randomly assigned and give target account Family.

Certainly, server can also verify the first account, if the verification passes, then generate the first contract.This hair Bright embodiment to verification mode without limitation.For example, server carries out resource transfers number and the total number resource of first account Compare, if resource transfers number is less than the total number resource, generates the first contract, otherwise, prompt the first account resource transfers Failure.

203, block head feature of the server based on the first block in the first contract, resource transfers request and block chain Value generates the second block, and the first block is a upper block for the second block on block chain, and the second block is for recording this money Source transfer request event.

In the step, server can obtain all information in the block head of the first block from block chain, and be based on All information in the block head of first block obtain the block head characteristic value of the first block, and to will be stored in the second block Block main body in the first contract information and resource transfers request carry out characteristic value calculating, obtain the block master of the second block The block head characteristic value of first block, the block body feature value of the second block (can also be included in turn version by body characteristics value This number, difficulty value and timestamp) it stores to the block head of the second block;By the information of the first contract and resource transfers request storage To the block main body of the second block, second block is generated, so that the second block and the first block pass through the block of the first block Head characteristic value is related, it is thus achieved that the purpose that the block in block chain is together in series, so as to information any in block (packet Include the information and resource transfers request of contract) distort, can be by the upper block that is stored in the block head of block Block head characteristic value retrospect and detect, to ensure that the safety of resource transfers process.

In actual application scenarios, it is contemplated that the information format of the first contract may be with each storage format in block chain not Matching, server can characteristic value based on the first contract, resource transfers request and the first block block head characteristic value, it is raw At the second block.In the implementation, server can carry out Hash calculation, the Kazakhstan that will be obtained to the every terms of information of the first contract Characteristic value of the uncommon value as the first contract, and the characteristic value of the first contract and resource transfers request are stored to the second block.It is logical The implementation is crossed, due to distorting to any information in the first contract, the characteristic value for the first contract being tampered can all sent out It is raw to change, and the characteristic value for the first contract being stored on block chain can not be changed, therefore distort all to any of the first contract It can be detected according to the characteristic value of the first contract on block chain, to ensure that the safety of contract.

204, server sends resource transfers message to target account.

In the step, server can be based on the first contract, generate resource transfers message, and resource transfers message is sent Terminal where to target account.The resource transfers message may include the information such as the first account and resource transfers numerical value.Specifically, Server can be disappeared based on the corresponding resource transfers number of target account each in contract, the resource transfers for generating the target account Breath, and send it to the target account.

In the embodiment of the present invention, in order to avoid Contract ID is forged, the safety of resource transfers process, server are improved Contract private key can be sent to target account, contract private key obtains contract private key signature and contract is public so that target account is based on Key, contract private key are sent to obtain by the first account.And in order to guarantee the safety of contract private key, the first account is sending this conjunction About private key when the contract private key can be encrypted using the Encryption Algorithm arranged in advance so that target account can also use The encrypted contract private key is decrypted in the decipherment algorithm arranged in advance, obtains the contract private key.It should be noted that The contract private key can be sent to server in another business packet sent except resource transfers request by the first account, by taking Business device extracts target account and contract private key from the business packet, and contract private key is forwarded to target account.Certainly, if First account is not based on contract private key and generates Contract ID, but generates Contract ID by other means, such as in privately owned area The Contract ID can be generated by the way of digital self-propagation under the scene of block chain, then the first account is without sending contract private Key, but Contract ID is directly sent to by target account by server, so that confirming or refusing resource transfers in target account When, server can be found according to the Contract ID that target account carries corresponding to the resource for confirming or breaking off relations with target account Contract.

205, target account sends confirmation resource transfers message to server.

In the step, when the terminal where the target account receives resource transfers message, can according to resource transfers message, Generate and show resource reception interface, which may include the corresponding resource transfers number of target account, the first account Family, the confirmation information such as option and rejecting option, when detecting trigger action of the target account to confirmation option, which can be with Confirmation resource transfers message is generated, and sends it to server, when detecting target account to the trigger action of rejecting option When, which can be generated refusal resource transfers message, and send it to server.Certainly, which can also select It selects and ignores the resource transfers message, e.g., close the resource reception interface.

It should be noted that the account identity in order to prove confirmation resource transfers, which can be using target account Account private key signs to the summary info of confirmation message to be sent, obtains account private key signature, which can To include the first account, target account and the corresponding resource transfers number of target account, and in order to guarantee what target account was confirmed Resource is corresponding with the resource of the first contract, and terminal can also be using obtained contract private key to the summary info of the confirmation message It signs, obtains contract private key signature, in turn, terminal can be obtained according to configured public key algorithm identical with the first account To the corresponding contract public key of contract private key, and the account public key with the pairing of account private key is obtained, it is private based on account public key, account Key signature, contract public key, contract private key signature, the corresponding resource transfers number of target account and confirmation message, generate the confirmation Resource transfers message.The process for generating refusal resource transfers message similarly, will confirm that information replaces with refusal information.

206, when server receives the confirmation resource transfers message of the second account, the identity of the second account is tested Card executes step 207, if not, ignoring the confirmation resource transfers message if the authentication of the second account passes through.

In the step, server can extract the every terms of information in confirmation resource transfers message, and the information based on extraction Verify whether the second account is the selected target account of the first account.Specifically, server can be based on confirmation resource transfers Contract public key, contract private key signature, account public key and account private key signature in message are verified, if the contract public key pair The contract private key signature is verified, and account public key is verified account private key signature, then available confirmation money The corresponding Contract ID of contract public key in the Transfer Message of source, and step 207 is executed, it, can if any one verifying does not pass through To ignore the resource transfers message.

In verification process, server can be decrypted contract private key signature by contract public key, if after decryption Summary info with confirmation resource transfers message in the summary info of confirmation message it is identical, the contract public key pairing can be confirmed About private key signature is verified;Server can also be decrypted account private key signature by account public key, if decryption Summary info afterwards is also identical as the summary info of confirmation message in confirmation resource transfers message, and account public key can be confirmed Account private key signature is verified.When obtaining Contract ID, server can be extracted from confirmation resource transfers message Contract public key out, and according to configured Contract ID algorithm identical with the first account and coding mode, obtain contract public affairs The corresponding Contract ID of key.

By the above-mentioned verification process based on key, both by account key authentication, the confirmation resource transfers message was come from It is the selected target account of the first account also by contract key authentication second account in the second account, therefore at this Under the mechanism of double verification, the safety and accuracy of resource transfers process are further improved.

207, whether server confirmation resource transfers message matches with the first contract, if so, based on the first contract, by the Two accounts are determined as target account, the corresponding resource transfers number of target account are transferred to target account, if not, ignoring the confirmation Resource transfers message.

In the step, server can will confirm that the information of information and the first contract in resource transfers message is compared Compared with, and according to comparison result, confirm whether resource transfers message matches with the first contract.

To make to confirm that matched condition is more stringent, to improve the correctness and safety of resource transfers process, service Device can judge to confirm the Contract ID of contract public key corresponding Contract ID and the first contract in resource transfers message respectively It is identical, whether the second account identical as target account, confirmation resource transfers message in resource transfers number whether match the first conjunction Whether the receiving time of resource transfers number, confirmation resource transfers message about is not later than the expiration time of the first contract, if on Stating judging result is to be, then meets the resource transfers condition of the first contract instruction, and server executes the code of the first contract, will Second account is determined as target account, it is transferred to the corresponding resource transfers number of target account to target account, if any of the above-described sentence Disconnected result be it is no, then server can ignore the confirmation resource transfers message.It should be noted that in actual application scenarios In, it can also not limited using foundation of the Rule of judgment as resource transfers at least one of therein, the embodiment of the present invention with which Several Rule of judgment do not limit the judgement timing of above-mentioned Rule of judgment as foundation yet.

Since first account may carry out resource transfers to multiple target accounts simultaneously, which can also be with specifically: Server searches whether exist and root according to the first account in confirmation resource transfers message in the contract list of the first account According to the identical Contract ID of Contract ID that confirmation resource transfers message obtains, if it is, it is corresponding to extract the Contract ID The expiration time of the corresponding resource transfers number of target account, each target account and the first contract, in turn, server can be sentenced Whether the receiving time for the confirmation resource transfers message of breaking is not later than the expiration time of the first contract, if so, may determine that this Whether the second account is identical as either objective account, if so, can continue to judge the resource in the confirmation resource transfers message It is identical to shift number resource transfers number whether corresponding with the target account in the first contract, if it is, can be to target account It is transferred to the corresponding resource transfers number of the target account.It should be noted that contract can be limited in order to improve the safety of contract The operating right of list for example, the contract list only allows to be read and written, and is forbidden being modified.

The embodiment of the present invention is by generating the first contract, and be based on when the resource transfers for receiving the first account are requested The block head characteristic value of first block in first contract, resource transfers request and block chain, generates the second block, and when meeting the When the resource transfers condition of one contract instruction, resource transfers are carried out based on the first contract, it can be based on front and back block in block chain Between incidence relation so that the information in block during any resource transfers can be transferred through the detection of next block when being tampered It arrives, avoids malice account and distort or deny the resource being transferred, ensure that the safety and reliability of resource transfers process, and And since the information of contract is also recorded in block chain, so that also can be by the conjunction that has been recorded in block chain when contract is tampered Information about is detected, and further ensures the safety and correctness of contract, improve resource transfers safety and can By property.

Moreover, an intermediate account in the prior art is often simultaneously multiple account services, so that in the intermediate account The money of transferring accounts that multiple accounts may be stored simultaneously causes intermediate account that mistakenly the money of transferring accounts for the user A that collects money may be transferred accounts To gathering user B, the fault-tolerance of resource transfers process is low.And the embodiment of the present invention each account initiate resource transfers when, The contract for this resource transfers process can be generated in real time for the account, each account of management can not only be facilitated Resource transfers process the design for simplifying system of account, ensure that the balance of account number of resources, and improve resource transfers The fault-tolerance of process, system performance limited problem when more avoiding an intermediate account while being a large amount of account services.

Moreover, the embodiment of the present invention can also neatly be applied in multiple resources transfer process, for example, multiple accounts are robbed Red packet, resource person to be received actively refuse resource or introduce the scene that third party arbitrates joint distribution resource.Wherein, third party Arbitrate the scene of joint distribution resource such as: third party's account extracts the number of resources of percentage from first resource transfer process.

It should be noted that the execution timing of above-mentioned steps 206 and 207 is exemplary, in fact, server can also be with It first carries out step 207 and executes step 206 again, or in order to improve resource transfers efficiency, be performed simultaneously step 206 and 207.Also want Illustrate, step 206-207 is the server in the embodiment of the present invention when meeting the resource transfers condition of the first contract instruction A kind of possible implementation that resource transfers are carried out based on the first contract, in fact, there is also other situations can meet first The resource transfers condition of contract instruction.The embodiment of the present invention is illustrated by taking situation 1 and situation 2 as an example:

Situation 1, server receive the refusal resource transfers message of the second account;If the authentication of the second account is logical It crosses, and refuses resource transfers message and matched with the first contract, be based on the first contract, the second account is determined as target account, to First account retracts the corresponding resource transfers number of target account.

In this case, server can be according to the contract public key in refusal resource transfers message, contract private key signature, account Public key, account public key signature and refuse information verify the identity of the second account, if verifying does not pass through, can ignore This breaks off relations resource transfers message, if the verification passes, then confirms the information and the first contract in the refusal resource transfers message Whether information matches, if so, the second account can be determined as to target account, and retracts the target account pair to the first account The resource transfers number answered, if it is not, then ignoring the refusal resource transfers message.Wherein, in specific verification process and step 206 Verification process is similarly;Specifically confirm in matched process and step 207 and confirm matched process similarly, will confirm that resource transfers disappear Breath replaces with refusal resource transfers message, and confirmation message replaces with refusal information and can be realized.

Situation 2, when server detects that the first contract reaches the expiration time of the first contract, be based on the first contract, to First account retracts the resource transfers number in the first contract.

In this case, server can be periodically detected the expiration time whether each contract reaches the contract, if so, The resource transfers number in the first contract can be then retracted to the first account, if it is not, then this detection process can ignore the conjunction About.

Based on above-mentioned resource transfers process, the surplus resources of resource and first account which has shifted are (real Border refers to the surplus resources in the resource of the first account request transfer) have it is following can be there are five types of situation:

One, first contract reaches the expiration time of the first contract, which is retracted into the first account, this The surplus resources number of one account is zero.

Two, target account be one, first account request transfer resource be fully transferred to target account, then this first The surplus resources number of account is zero.

Three, target account is one, and the resource of first account request transfer is refused by target account, and resource transfers number moves back It is back in the first account, the surplus resources number of first account is zero.

Four, target account be it is multiple, first account request transfer resource part be transferred to target account, then this first The resource transfers number that the surplus resources number of account is greater than zero and is less than in resource transfers request.

Five, target account is multiple, and the resource of first account request transfer is refused by target account, the target account pair The resource transfers number answered is retracted into the first account, and the surplus resources number of first account, which is greater than zero and is less than resource transfers, requests In resource transfers number.

For situation one to three, since the resource transfers process that first account is initiated has been fully completed, in order to avoid Go back on one's word or deny either during the resource transfers, and avoids repeating first contract to target account or the first account Family is shifted, to improve preciseness and the safety of resource transfers process, server can be set the first contract to Completion status, the embodiment of the present invention are not specifically limited the mode of setting, for example, server can close for the addition of the first contract Mark is about completed, alternatively, the account of transferring resource and corresponding transferring resource number are added in first contract, due to this Transferring resource number is identical as the number of resources that the first account request shifts, be equivalent to identify first contract whole resources are completed Transfer, alternatively, a new resource transfers number is added in first contract, and the resource transfers number is zero, so that server Mark or newest resource transfers number is completed based on the contract in first contract of resource will not execute resource transfers again.

It should be noted that in order to guarantee that contract correctly executes, and resource transfers process is correct, and resource occurs every time and turns It moves, which will be updated, but deny or distort contract in order to avoid having carried out the account of resource transfers, and when update is not Information stored in first contract is modified, but adds more new information in the first contract, server is subsequent to be based on When first contract carries out resource transfers, need to carry out resource transfers based on more new information newest in the first contract, for example, base The timestamp of more new information in the first contract obtains most newly added more new information, and based on the most newly added update letter Breath carries out resource transfers.

When being set as first contract that state is completed, server can the first contract based on the state that is completed, The block head characteristic value for triggering the 5th block in the message and block chain of this resource transfers completion generates the 6th block, the Five blocks are a upper block for the 6th block on block chain, and the 6th block, which is used to record, triggers the thing that this resource transfers is completed Part.Wherein, the message for triggering the completion of this resource transfers can detect that the first contract reaches arriving for the first contract for server The message of time phase, alternatively, the confirmation resource transfers message of target user or the refusal resource transfers message of target user.

For situation four and situation five, continuation of the embodiment of the present invention is illustrated with step 208 and step 209:

208, the first contract of server update, updated first contract are used to indicate the surplus resources transfer of the first account Condition.

In the step, it is contemplated that the resource of the first account has partially been transferred to a target account or part is retracted into the Therefore one account carries out resource transfers in order to continue as other accounts in multiple target accounts, server can be based on First contract has confirmed that (or refusal) resource transfers target account and transferring resource number, adds and updates in the first contract Information completes the renewal process of the first contract, which obtains according to the resource transfers process carried out, the more new information It can be there are many expression-form.For example, the more new packets include account (the first account or the target account for having carried out resource transfers Family) and corresponding resource transfers number, it can be according to the letter recorded in the more new information and the first contract so that server is subsequent Breath, determines current target account and the corresponding resource transfers number of each target account.It is somebody's turn to do in another example the more new packets include to remove The remaining target account and the corresponding resource transfers number of remaining target account except the account of resource transfers have been carried out, then has been taken Being engaged in, device is subsequent directly to carry out resource transfers according to the more new information.

It should be noted that this since target account may have multiple, and the interaction message based on each target account One contract will be updated, therefore, in first contract may record repeatedly more new information, server based on first contract into When row resource transfers, resource transfers can be carried out based on newest more new information according to the timestamp of more new information.

209, server is based in updated first contract, the interaction message and block chain that trigger this resource transfers The block head characteristic value of third block generates the 4th block, and third block is a upper block for the 4th block on block chain, the Four blocks complete event for recording this resource transfers.

In the step, server can the information (spy of such as updated first contract based on updated first contract Value indicative), in confirmation resource transfers message (or refusal resource transfers message) and block chain third block block head characteristic value, Generate the 4th block.The block generating process of specific generating process and step 203 is similarly.

In fact, it is subsequent before the expiration time of first contract, if server receives some target account Confirm resource transfers message or refusal resource transfers message when, can also continue to based on step 206 and 207 verification process and Confirmation matching process is made to determine whether to carry out resource transfers, and when determining resource transfers, updates contract and generate new area Block.Alternatively, if server does not receive the interaction of any target account yet when the expiration time for reaching first contract Surplus resources in first contract then can be shifted number and be retracted into the first account, and set the first contract to by message Completion status and and generate new block.

When first account is to multiple target account transferring resources, if some target accounts in multiple target account Family has been acknowledged (or refusal) resource transfers, and other target accounts are confirmed or refused not yet, then first conjunction Resource transfers number about disposably will not be shifted all, then in order to which the whole resources for guaranteeing that first account request shifts can turn It moves, perfect resource transfers service is provided for user, server also needs to continue according to the surplus resources of first account Resource transfers can not only avoid having shifted during previous resource transfers by updating the first contract and generating the 4th block Transfer record is denied or distorted to the account of resource, additionally it is possible to accurately execute resource next time according to updated first contract Transfer process, further such that the number of resources during resource transfers keeps balance.
