Abstract
The invention discloses a disordered signing and sealing method based on an intermittent communication model, which includes that a contract countersigning server locks a countersigning contract of a contract initiating client side to be a contract with contents without being amended and only allows one client side to perform contract countersigning at the same time. The disordered signing and sealing method based on the intermittent communication model is characterized in that: (i) the contract countersigning server presets a contract editing overtime value Tc and a contract countersigning time interval value Tu updated at fixed time, wherein Tu<Tc; (ii) the contract countersigning server records the last edited time Te of the countersigning contract, wherein the initialized value of the last edited time Te is a time value far away from the current contract establishing time; and (iii) judging execution mode of contract request with the last edited time Te and the contract editing overtime value Tc until closing contract countersigning. The disordered signing and sealing method effectively solves problems that contract files are locked during signing of disordered countersigning caused by the network or other sudden faults, and leads the whole contract countersigning to be conducted smoothly with no obstacles.
Description
Technical field
The present invention relates to a kind of unordered signature method, belong to areas of information technology.
Background technology
Information industry in modern times; The contract signature of electronization is one of most important electron communication activity, and existing contract is conutersigned system, mainly is in-line official document flow system and countersign circulation system; Whole contract signature process series connection is carried out; Its service logic is with reference to shown in the accompanying drawing 1, in the countersign flow process, because the characteristic of transmission course itself; File transfer is that the source file that a last signatory signed oneself duplicates a copy through mail or internal application system, sends the next bit signatory to.In this process, the uniqueness of source file has been destroyed, and simultaneously, the consistency of the content of file does not have technical guarantee means, and treaty content possibly be modified.In the time of the signatory of N position, will exist N part that varying number signatory's contract text is arranged, buried hidden danger for the fail safe of contract, do not meet the requirement of " the international contract of the United Nations uses the electronic communication pact ".Secondly; Because the series characteristic of flow process; Each signatory must just can sign after a last signatory has accomplished signature; If delay has taken place a certain link in cascade process, the time of the completion of whole countersign can be delayed greatly, so the signature of series system is also relatively low on efficient.
To above-mentioned defective, the contract countersign method based on parallel flow process has also appearred in this area at present, shown in accompanying drawing 2; This parallel flow phase inversion has improved efficient than the series connection circulation, but same, is not well-determined in circulation process file; But many parts of duplicates of the document are sent to object to be signed; Concentrate then and gather, therefore also there is potential safety hazard in this countersign pattern, does not meet the requirement of " the international contract of the United Nations uses the electronic communication pact ".
Summary of the invention
Low in order to overcome the efficient that existing contract countersign method exists; File security is relatively poor; Defectives such as legal assurance property is relatively poor; The applicant provides a kind of contract countersign method based on the unordered countersign pattern of many people in studying in early days; And with regard to the correlation technique application patent (201210022030.3 1 kinds of one Chinese patent application countersign method and system, 201210022611.7 1 kinds of low consumed electronic business contract countersign methods of one Chinese patent application), described its basic procedure of contract countersign method is as shown in Figure 3, comprises the steps:
1) promoter's client will upload onto the server without the original contract of stamped signature or on server, set up original contract with contract template;
2) can't permit the source contract of modification in server is locked as the original contract authority, notice is given the countersign person's client with contract stamped signature authority simultaneously;
3) the countersign person's client that has a contract stamped signature authority is made the whether decision of stamped signature to contract, and server record has the stamped signature daily record of countersign person's client of contract stamped signature authority;
4) server gathers stamped signature, and the contract stamp result is returned the client to the promoter, and the server record contract is accomplished countersign result's daily record.
In order to guarantee that client in the whole contract countersign process can in time learn server contract countersign situation and result's information, step 3) comprises also whether other countersign person's clients with contract stamped signature authority of countersign person's client that server notification has a contract stamped signature authority agree the step to the contract stamped signature; Said step 3) comprises also whether countersign person's client that server notification promoter client has a contract stamped signature authority agrees the step to the contract stamped signature.
In said process, advice method can be the Notification Method of computer and communications field any known, preferably SMS notification and/or mail notification.
Described contract countersign method comprises also that further promoter's client files, abandons, cancels the step of its original contract of uploading at server; To adapt to the multiple different situations that face in the actual contract signature process; For example the ecommerce both sides in negotiations process, do not reach an agreement cancel a contract, since change in contract terms abandon contract etc.; Same, after contract produced above-mentioned variation, server was with above-mentioned information notice client.Countersign person's client of described contract countersign method promoter client, contract stamped signature authority is a personal computer; The both sides of contract signature or all upload contract through personal computer to server in many ways perhaps set up contract through personal computer contract template with server end on server.
Described contract countersign method signature method is for to carry out Electronic Signature to contract, promptly with enterprise's seal, and individual seal, the integrated encryption of handwritten signature and digital watermarking are encrypted, and have guaranteed the unforgeable of seal.Described encryption and digital watermarking can be any known encryption method in this area and digital watermarking type, especially can be the early stage breakable watermarks of realizing of the application applicant.
Through said contract countersign method; The user uploads onto the server contract text just can begin not have the countersign of flow process restriction; A source contract unique in whole countersign process is locked and can't changes, and all operation notes of countersign user all can be kept in the daily record of backstage.This mode had not only improved efficient but also had guaranteed the uniqueness and the tamper-resistance properties of signed instrument.
Although above-mentioned contract countersign method based on unordered countersign pattern has guaranteed fail safe again when having guaranteed countersign efficient; Yet still there are some problems in it; Mainly be when carrying out the contract countersign, after certain countersign client is opened contract, the automatic contract of record state of system (being opened); When the residing network of this countersign client, the residing network of server or network are between the two closed the huge delay of train appearance suddenly owing to force majeure; Because system can't upgrade or handle the state of contract in time; Cause contract to be in the state that is opened always; In fact the contract that makes is locked, and can't carry out signing to next one countersign person client.Consider the network application present situation of domestic complicacy and the network of cutting apart each other, this kind situation is particularly outstanding.
To the problems referred to above, the invention provides a kind of unordered signature method based on communication at intermittence model, overcome the blocked problem that contract in the said method causes owing to network reason or other reasons.
In order to realize the foregoing invention purpose, the present invention realizes through following technical proposals:
A kind of contract countersign method based on communication at intermittence model; Comprise that contract countersign server locking contract initiates the meeting of client and sign a contract and can't permit the contract of modification and only allow a client to carry out the step that contract is conutersigned at one time for interior, it is characterized in that:
(i) said contract countersign server preestablishes contract editor timeout value Tc and the contract countersign time interval value Tu that regularly upgrades, wherein Tu＜Tc;
(ii) said contract countersign server record can sign a contract at last by edit session Te, said is away from the current contract time value of settling time by the initialized value of edit session Te at last;
(iii), close until the contract countersign to be judged the executive mode of the request of editor's contract at last by edit session Te and contract editor timeout value Tc.
Wherein, according to step (iii), executive mode is: Te+Tc≤contract countersign current time Now, but open contract with edit mode; On this basis, but after opening contract with edit mode, execution in step (iv): every Tu time is upgraded Tc one time, is updated to Now, to Tc＜-Now, finish to contract editor item.
Wherein, according to step (iii), executive mode be (v): Te+Tc＞Now, open contract with read-only mode; On this basis, open contract with read-only mode, every Tu time is asked editing authority one time, and the execution of described request according to step is (iii) closed to contract.
Through technique scheme, effectively avoided contract documents in unordered countersign because network or other catastrophic failures and blocked problem has guaranteed the safe and orderly circulation of whole countersign flow high efficiency.

Fig. 2 is existing parallel mode contract countersign schematic diagram;
Fig. 3 is the contract countersign flow chart based on unordered stamped signature model of applicant's earlier application.
Embodiment
Following execution mode is merely example; Be used to explain how unordered signature method of the present invention is realized; Those skilled in the art are understanding the change of being carried out on the basis of matter in fact, like timeout value, blanking time, at last by the conversion of edit session etc., still belong to protection scope of the present invention.
A kind of unordered signature method based on communication at intermittence model comprises the steps:
(i) the countersign platform was at first set editor's timeout value Tc, as 3 minutes.Set a time interval value Tu who regularly upgrades again, as 2 minutes.Relation between the two is Tu＜Tc.
(ii) every part of contract all writes down at last by edit session Te, and this value is initialized to away from one of the current time very little value, like New Year's Day in 2000 (using Now to identify the current time).
(iii) the request of any one editor's contract will be by such execution: if Te+Tc≤Now, but can edit mode open contract; Otherwise can only open with read-only mode.
But the contract of (iv) opening with edit mode, every Tu time is upgraded Tc one time, is updated to Now, promptly Tc＜-Now.This intermittence is upgraded and is continued to the end of contract editor item.
(contract of v) opening with read-only mode, every Tu time is asked editing authority one time.The execution of this request is of (iii), and this intermittence request continues to contract and closes.
