In one embodiment, which is used to carry out Identity Management to user node 411 and accounting nodes 413 And authentication.Wherein, which enters in block chain network for new node user's registration, and archives text is occurring When part relationship trading, corresponding intelligent contract is matched according to relevant identity information.Specifically such as, new node is sent to management node Account Registration request, wherein account registration request includes that the account name of request registration (is provided in user after succeeding in registration to log in The block chain network) and the new node the provable user such as identity information, such as identification card number, passport No., enterprise number The information of identity.Wherein, account registration request can also only include the identity information of user node.Management node is by Account Registration Identity information in request is compared with the identity information in default identity database；If default identity database there is no The identity information matched, then authenticate and do not pass through, and returns to the registration failure message comprising failure cause；If default identity data inventory In matched identity information, then certification passes through, and sends the message that succeeds in registration.Further, management node can also be by Account Registration Identity information in request saves to setting and manages database, to be managed collectively the user identity for participating in the block chain.New node After receiving the message that succeeds in registration, the related algorithm in self-operating block chain technology or other sections by block chain network Point generates block chain address, the block chain address of the account as registration for it；And the phase in self-operating block chain technology It closes algorithm such as setting Hash operation and generates the public key and private key of one group of public key and private key as the account of registration.Then, new node By the public key broadcasts in the block chain network, so that the account that other nodes in network receive and save the user's registration is public Key.Also, its private key and block chain address are stored in local or the private key and also can be transmitted in the credible of setting by the new node The node appointed is stored, to back up.At this point, Account Registration is completed.

The block chain network of the present embodiment is by taking alliance's chain network or privately owned chain network as an example, i.e., block chain network is added in node When need to carry out identity information registration, the member's node for the identity information only registered could visit the block chain network It asks.

Referring to Fig. 5, Fig. 5 is the flow diagram of the application archive management method first embodiment.As shown in figure 5, this The archive management method of embodiment may include following steps:

In step s 11, user node obtains corresponding with files to be borrowed the be stored in block chain network One archives mark.

User node obtains the first archives corresponding with files to be borrowed of filing and storage from block chain network Mark, it is to be understood that the first archives are identified as to pass through this when borrowing files and carrying out filing storage and scan in it Hold the archives mark generated, i.e., it is understood that the first archives mark corresponds to when borrowing files and carrying out filing storage Content.Further, the first archives mark can be first corresponding to content when borrowing files and carrying out filing storage Archives two dimensional code.

In the present embodiment, by taking the corresponding staff for file administration of user node as an example.When borrowing user to archives The staff of management proposes the Requirement of files, is believed by the archives that user node typing needs to borrow files Breath, such as archives kind, file name, archives affiliated date, archives voucher number.User node is according to the archive information of typing The first archives corresponding with files to be borrowed mark of filing and storage is obtained from block chain network.

When borrowing files filing storage, the content of the files to be borrowed can be scanned, and then generate Store corresponding with the content of files to be borrowed the first archives mark when borrowing files, user node obtain this One archives mark, and sends it to block chain network so that the accounting nodes in block chain network to the first archives identify into Row book keeping operation.Further, files to be borrowed can be archives of paper quality file, be also possible to electronic record file, also can wrap The electronic record duplicate of the document for including archives of paper quality file and being formed by the archives of paper quality file.If files to be borrowed include When electronic record file, electronic record file can also be also uploaded to block chain network, so that the book keeping operation in block chain network Node keeps accounts to electronic record file, and electronic record file also is stored in block chain network.

In other embodiments, the staff for managing archives can scan files to be borrowed by scanning device First archives mark, files to be borrowed accordingly are searched, can check the files to be borrowed storage information, It borrows record, give back the information such as record, realize the retrospect to the life cycle of files.If files have the management phase Limit, when its manage time limit expire and it is destroyed or nullify when, still can by scan files to be borrowed the first archives identify It to its storage information, record is borrowed, gives back the information such as record and consults, carry out life cycle retrospect.

In step s 12, the second gear pattern identification that the content based on files to be borrowed generates is obtained.

Further, when borrowing Requirement of the user to the staff of file administration proposition files, pass through user Node typing needs to borrow the archive information of files, such as archives kind, file name, archives affiliated date, archives voucher Number etc..User node is according to the content that the archive information of typing can obtain corresponding files to be borrowed corresponding Two archives mark.

In the present embodiment, second gear pattern identification be it is current according to the archive information that user's offer is provided find wait borrow The archives mark that the content of files generates, i.e., it is understood that second gear pattern identification corresponds to the archives to be borrowed found The current content of file.Further, second gear pattern identification can be for corresponding to the current of the files to be borrowed found Content the second archives two dimensional code.

It waits borrowing when storing with filing it is understood that the execution content of step S11 and step S12 is respectively used to obtain The corresponding first archives mark of the content of files and the second archives mark corresponding with the currently content of files to be borrowed Know, between the two there is no the restriction of specific successively execution sequence, i.e., in other embodiments, step S12 can also first be held It goes, is executed after step S11, the application is not particularly limited.

In step s 13, the first archives mark and second gear pattern identification are compared, are judged according to comparison result wait borrow Read whether files are correct, and judges whether to receive and be verified information to borrow that user carries out authentication.

Further, the first archives mark and second gear pattern identification that will acquire are compared, and are judged according to comparison result Whether files to be borrowed are correct.Since the first archives mark and second gear pattern identification correspond respectively to files to be borrowed Current content and treating borrow content when files carry out filing storage；It follows that if the first archives mark and Second gear pattern identification is consistent, then illustrates that the current contents of files to be borrowed is deposited with treating to borrow files and carry out filing Content when storage is also consistent, can determine whether that files to be borrowed are correct in other words；If the first archives mark and second gear Pattern identification is inconsistent, then the files to be borrowed stored in files and the block chain network to be borrowed that explanation is found are not It unanimously, at this time may be to find files mistake to be borrowed, or files to be borrowed are from filing storage to this lookup In a period of there is modification, situations such as damage, partial content are lost, in other words, can determine whether that files to be borrowed are not just True, therefore cannot lend.

Further, the present embodiment is when borrowing user and borrowing files, also needs to carry out authentication to borrowing user, i.e., File administration user node also needs to determine whether the authentication for borrowing user passes through.I.e. file administration user node also needs to confirm Whether receive and be verified information to borrowing user and carry out authentication, corresponds to if file administration user node receives The information that is verified for borrowing user then illustrates to have carried out authentication to borrowing user, and authentication passes through；If shelves Case management user node, which does not receive to correspond to, borrows the information that is verified of user, then illustrates not carry out to borrowing user also Authentication, or to subscriber authentication exception is borrowed, user can not be borrowed to this at this time and lend files to be borrowed.

In step S14, record is borrowed according to the identity information for borrowing user and files to be borrowed generation, will be borrowed Record is sent to block chain network.

According to the comparison and judgement of step S13, when judging result is that files to be borrowed are correct, and receive and correspond to When being verified information of user is borrowed, i.e., explanation can borrow user's lending to this and be somebody's turn to do files to be borrowed.At this point, record is borrowed Read the identity information of user, the associated profiles information of files to be borrowed, borrow temporal information etc., it is generated according to these information It is corresponding with the files to be borrowed to borrow record, record will be borrowed and be sent to block chain network, the note in block chain network Account node borrows record to this and carries out common recognition book keeping operation, forms new block and is stored in block chain network.

In step S15, feedback borrows failure information.

According to the comparison and judgement of step S13, when judging result is that document to be borrowed is incorrect and/or do not receive correspondence In borrowing when being verified information of user, that is, can determine cannot lend files to be borrowed to user is borrowed, and feeds back and borrow Failure information is read, further, it is also possible to which the particular content of judging result further to be fed back to the staff of file administration.

When judging result be wait borrow files it is incorrect when, it may be possible to find files mistake to be borrowed, or There is situations such as modification, damage, partial content loss in files to be borrowed in a period of searching from filing storage to this, Also file to be borrowed can be prompted incorrect in the colleague that feedback borrows failure information.Testing for user is borrowed when not receiving to correspond to Card is when passing through information, illustrate also not carried out authentication to borrowing user, or abnormal to subscriber authentication is borrowed, feed back It can also prompt to carry out the unacceptable verification result of authentication to borrowing user when borrowing failure information, or inform not to borrowing use Family carries out authentication.

The present embodiment borrow user treat borrow files and borrow when, enable that user node utilizes and filing stores When files to be borrowed the corresponding first archives mark of content and corresponding with the currently content of files to be borrowed the Two archives mark is borrowed the contents of files and confirm to treat, and is lent when borrowing files with having ensured, should The consistency of the content of files to be borrowed, files especially to be borrowed are that preservation pipe is carried out in the form of paper document When reason, can guarantee the correctness of paper document, and can be treated by block chain network borrow the Borrow Situations of files into Row storage, treats the Borrow Situation for borrowing files, storage condition etc. by block chain network convenient for administrative staff and looks into It askes.Further, in the present embodiment, only when correct and when borrowing the authentication of user and passing through wait borrow files, just may be used To borrowing user's lending, archives text is avoided by treating to borrow files and borrow the dual verification process of identity of user There is situations such as mistake is borrowed in part.

Further, referring to Fig. 6, carried out on the basis of archive management method first embodiment shown in Fig. 5 into one Step extension.As shown in fig. 6, may also include the steps of: before step S11 shown in Fig. 5

In step s 16, user node obtains file borrowing request, corresponding wait borrow based on file borrowing request The storage address of files, and corresponding the is generated based on the content of the files to be borrowed found using storage address Two archives mark.

Borrow the file borrowing request that user proposes files to the staff of file administration, file borrowing request It can be also to borrow user and directly pass through the user node of appeal to propose, be also possible to propose by other electronic equipments of oneself 's.It wherein, may include the relevant archive information for needing the files to be borrowed borrowed in file borrowing request, such as archives class Not, file name, archives affiliated date, archives voucher number etc..In different concrete applications, files to be borrowed can be with paper The form of matter files carries out preservation and management；Can also in the form of electronic record file storage and management；Can also be with The form of archives of paper quality file carries out preservation and management, while forming electronic record duplicate of the document according to archives of paper quality file, will Electronic record duplicate of the document storage and management in the form of electronic record file.Wherein, it is stored in the form of electronic record file And management, electronic record file are storable in block chain network, also can store in the database except block chain network, In addition, other storage methods also can be used by its part there are in block chain network, another part be stored in block chain network it In outer database.

In the present embodiment, user node according to file borrowing request in include these archive informations can inquire wait borrow Read the storage address of files.And then files to be borrowed accordingly can be found by the storage address, it is real one It applies in mode, the corresponding electronic equipment of user node can have scanning function or the corresponding electronic equipment of user node that can connect Scanning device；As a result, the scanning function or and user node of user node can be utilized after finding wait borrow files The scanning device of connection, which is treated, to be borrowed files and is scanned, and then generates corresponding with the content of files to be borrowed the Two archives mark.It is understood that second gear pattern identification corresponds to the current content of the files to be borrowed found.

The present embodiment, can by 813 pairs of scanning device when the accounting file file bound into book form to filing carries out storage storage Meter files are scanned, and form corresponding archives mark, and archives mark is above-mentioned the first archives mark, shelves Pattern identification can be archives two dimensional code；Archives are identified after generating by user node 811 and are uploaded to block link network by archives mark Network 814 keeps accounts to archives mark by the accounting nodes (being not drawn into figure) in block chain network 814, and is stored in block In chain network 814；Corresponding accounting file file is then stored in corresponding accounting file database.

In addition, occurring between accounting file file borrows, borrow user and/or file administration staff and its His node needs to carry out identity registration；When registration, biology that each user passes through the electronic equipment typing itself of corresponding node Feature is as registration biological characteristic, while the identity information of typing oneself, user node 811 can give birth to registration using hash algorithm Object feature carries out Hash calculation, obtains registering digital finger-print accordingly, and registration digital finger-print and identity information are associated, and It is uploaded to block chain network 814；Accounting nodes in block chain network 814 register digital finger-print and identity letter to being mutually related Breath carries out book keeping operation storage, carries out authentication to user when in order to the events such as borrow, give back, the identity letter stored at this time Breath is enrollment status information.

Further, after completing identity registration, user node 811 can also generate corresponding private key at random, and according to private key Public key is calculated, public key is uploaded to each node in block chain network 814, private key is stored in the user node.It needs Illustrate, the present embodiment is also to carry out accounting file file by user node 811 to borrow to borrow user, therefore can not needle Public key and private key are generated to user is borrowed, only the node with administration authority (such as staff of file administration) is generated public Key and private key.

Further, after borrowing user's completion identity registration, user node 811 can be believed based on the enrollment status for borrowing user Breath matching obtains corresponding intelligent contract, and the intelligence contract is deployed to each node in block chain network 814, so that area Block chain network 814 is based on intelligent contract and executes transaction related to user.

When borrowing user and needing to borrow accounting file file, provided to the staff of file administration need to borrow wait borrow The archive information for readding accounting file file (as above-mentioned files to be borrowed), such as archives kind, file name, archives institute Belong to date, archives voucher number etc.；In addition it is also necessary to which the identity information for borrowing user itself to be supplied to the work of file administration Personnel, the staff of file administration is by the above-mentioned archive information being provided and identity information typing user node 811, Yong Hujie Point 811 obtains above-mentioned archive information and identity information.It should be noted that the staff of file administration is inciting somebody to action in the present embodiment Before the above-mentioned archive information and identity information typing user node 811 that are provided, also need to be stepped on by user node 811 Record, at this point, the staff of file administration to the corresponding log-on message of 811 typing of user node (may include biological information, One of identity information, account information are a variety of), user node 811 obtains above-mentioned log-on message, utilizes the private being locally stored Key encrypts log-on message, and encrypted log-on message is transmitted to block chain network 814, in block chain network 814 Verifying node obtain corresponding public key, be decrypted using log-on message of the public key to encryption, stepped on according to what is obtained after decryption Record authentication and the register of the staff of information completion file administration.

Further, 811 one side of user node should be wait borrow from the storage of accounting file database lookup according to archive information The storage address of accounting file file, to find the accounting file file to be borrowed according to the storage address, by what is found Accounting file file to be borrowed is provided to scanning device 813, by scanning device 813 to the accounting file file to be borrowed found Content be scanned, formed correspond to find accounting file file to be borrowed archives mark, as above-mentioned second Archives mark, and second gear pattern identification is sent to user node 811.On the other hand, user node 811 is based on being believed according to archives Breath obtains corresponding first archives mark from block chain network 814, and the first archives mark and second gear pattern identification are carried out It compares, is verified according to correctness of the comparison result to the accounting file file to be borrowed found, is i.e. verifying is found Wait borrow the content of accounting file file and treat whether borrow content when accounting file file carries out filing storage consistent.Again On the one hand, it borrows user and passes through the certification biological characteristic of 812 typing of physical characteristics collecting equipment oneself, and biological characteristic will be authenticated It is sent to user node 811, Hash calculation is carried out by 811 pairs of certification biological characteristics of user node, obtains certification digital finger-print, into One step, user node 811 obtain corresponding registration number according to the identity information for borrowing user's offer from block chain network 814 Fingerprint, carrying out authentication to user using certification digital finger-print and registration digital finger-print, (in other embodiments, calculating is recognized Digital finger-print is demonstrate,proved, and comparing certification digital finger-print can also be by physical characteristics collecting equipment with the execution content for registering digital finger-print 812 execute).If user node 811 determines that the accounting file file to be borrowed found is correct, and borrows the authentication of user Pass through, it is determined that the accounting file file to be borrowed found can be lent to this and borrow user, and formed and borrow record accordingly, It record will be borrowed is uploaded to block chain network 814 and store.

Further, intelligent contract could dictate that the lending time limit of accounting file file and the penalty mechanism that do not give back that exceeds the time limit. After borrowing record and being uploaded to block chain network 814, that is, it can trigger corresponding intelligent contract, start the time lent to it progress Record can trigger intelligence contract from trend and borrow user's transmission when not giving back in the lending time limit for reaching accounting file file It gives back and reminds and/or execute automatically the penalty mechanism for exceeding the time limit not give back；For example, by including into the identity information for borrow user Telephone number or email address, to corresponding mobile phone or mailbox transmission give back prompting.Further, it can also be mentioned from having sent to give back Further record lends the time when awake, recognizes after a period of time and does not give back accounting file file, then is held automatically based on intelligent contract The corresponding penalty mechanism of row.

Authentication is had already been through when logging in due to the staff of file administration in the present embodiment, it can be with It does not need to carry out authentication to it by the biological characteristic of the staff of file administration again, but in other embodiments, Authentication can also be carried out to the staff of file administration in the way of digital finger-print using above-mentioned, such as need to lend Accounting file file to be borrowed there is situations such as higher secret grade, need to obtain specific people's annotation when could lend.This Outside, in other embodiments, block chain network can also be added by mobile phone, the apparatus such as computer of oneself by borrowing user, this When borrow user can also be by the way of above-mentioned login authentication.

Further, referring to Fig. 9, Fig. 9 is the flow diagram of the application archive management method fourth embodiment, this implementation Example for being lent after borrowing files in archive management method first embodiment shown in fig. 5, carry out what archives were given back Embodiment.As shown in figure 9, the archive management method of the present embodiment may include following steps:

In step S31, user node obtains the third gear pattern identification that the content based on files to be given back generates.

When giving back user's (i.e. corresponding under normal circumstances to borrow user with above-mentioned) and giving back files, to user node (the present embodiment is by taking file administration user node as an example) provides files to be given back, and is similar to step S11, user node at this time According to user's files to be given back of offer are given back, third archives mark corresponding with the content of files to be given back is obtained Know.

In another embodiment, user node can treat give back files content be scanned so that obtain with to Give back the corresponding third gear pattern identification of content of files.

In step s 32, the first archives mark corresponding with files to be given back being stored in block chain network is obtained Know.

In the present embodiment, files to be given back should correspond to the files to be borrowed of above-mentioned lending, store as a result, The corresponding first archives mark of files in block chain network and to be borrowed is corresponding with files to be given back Archives mark.Content step S12 as shown in Figure 5 is executed, according to user's files to be given back of offer are given back, phase can be obtained Such as archives kind, file name, archives affiliated date for answering, archives voucher number archive information, and then from block chain network It is middle to obtain corresponding first archives mark.

In step S33, the first archives mark and third gear pattern identification are compared, judged according to comparison result wait return Also whether files are correct, and judge whether to receive and be verified information to give back that user carries out authentication.

First archives mark and third gear pattern identification are compared user node, judge shelves to be given back according to comparison result Whether case file is correct.It is understood that if the first archives mark it is consistent with third gear pattern identification, illustrate at this time wait return Also files are the files to be borrowed lent before, that is, files to be given back are correct；If the first archives mark Know it is consistent with third gear pattern identification, then illustrate files to be given back at this time and the files to be borrowed lent before not Together, that is, files to be given back are incorrect, at this point, files to be given back may give back mistake, or the process in lending In there is situations such as partial content loss.

Further, the present embodiment is when giving back user and giving back files, also needs to carry out authentication to giving back user, i.e., User node also needs to determine whether the authentication for giving back user passes through.I.e. user node also needs to be confirmed whether to receive to giving back User carries out authentication and is verified information, if user node receive correspond to give back user be verified information, Then illustrate to have carried out authentication to giving back user, and authentication passes through；Return if user node does not receive to correspond to Also user is verified information, then illustrates also not carried out authentication to giving back user, or to giving back subscriber authentication It is abnormal, can not complete at this time this give back user treat give back file give back operation.

In step S34, record is given back according to the identity information for giving back user and files to be given back generation, will be given back Record is sent to block chain network.

According to the comparison and judgement of step S33, when judging result is that files to be given back are correct, and receive and correspond to When being verified information of user is given back, i.e., explanation can give back user to completion and give back operation to the files to be given back. At this point, record the associated profiles information of the identity information, files to be given back of giving back user, give back temporal information etc., according to These information generate that files to be given back are corresponding gives back record with this, will give back record and are sent to block chain network, block Accounting nodes in chain network give back record to this and carry out common recognition book keeping operation, form new block and are stored in block chain network.

In step s 35, feedback gives back failure information.

According to the comparison and judgement of step S33, when judging result is that document to be given back is incorrect and/or do not receive correspondence In giving back when being verified information of user, that is, can determine cannot complete to give back user treat give back files give back behaviour Make, and feed back and give back failure information, further, it is also possible to which the particular content of judging result further to be fed back to the work of file administration Make personnel.Particular content can be as shown in Figure 5 step S15 content, details are not described herein again.

Further, the application also proposed the user information management method based on block chain technology, the user of the present embodiment Approaches to IM can be applied to the file administration network shown in Fig. 4 based on block chain technology.Referring to Fig. 10, Figure 10 is this Apply for the flow diagram of user information management method first embodiment, as shown in Figure 10, the present embodiment may include following process:

In step S41, user node obtains the registration biological characteristic of user's typing, carries out Hash to registration biological characteristic Corresponding registration digital finger-print is calculated.

Block chain network can be privately owned chain network or alliance's chain network in the present embodiment, and user needs in advance to block chain Network is registered, and could be approved by other nodes in block chain network after succeeding in registration to carry out phase by block chain network The transaction answered.In the present embodiment, when user's registration block chain network, typing its own biological characteristic it is special as registration biology Sign, user node obtains the registration biological characteristic, and obtains the character string of irreversible one group of regular length using Hash calculation, The character string can be used as registration digital finger-print corresponding with registration biological characteristic.

In step S42, the enrollment status information of user's typing is obtained.

When user's registration block chain network, as enrollment status information, user node obtains its own identity information of typing Take the enrollment status information.

In the present embodiment, registering biological characteristic can be the physiological characteristic of any one or a few user, such as fingerprint, rainbow Film, face at least one of refer to the physiological characteristics such as vein.Enrollment status information may include the physics of one or more of users Identity information, such as ID card information (ID card No., native place, identity card picture), job information (work unit's title, work Make part, position etc.), household register information, at least one of contact method (phone, mailbox, QQ, wechat etc.).

In step S43, registration digital finger-print is associated with enrollment status information, and be stored in block chain network In.

Further, the registration digital finger-print and enrollment status information that user node will acquire are associated, and are uploaded to The accounting nodes of block chain network, block chain network keep accounts to registration digital finger-print and enrollment status information, complete user To the identity registration of block chain network.

The user information management method of the application is no longer individual special using biology in user's registration block chain network Sign or identity information are registered, but the two is associated to register.In addition, the application is in user's registration block chain Cochain is the registration digital finger-print being calculated according to the registration biological characteristic of user when network, which is not It is reversible and unique, therefore the user information management method of the application can guarantee that the privacy of user is more not easy to be leaked, and Authentication more accurately can be carried out to user when user's later use block chain network carries out relationship trading, reduce identity The case where authentication error.
