Description of drawings
Below by embodiment, in conjunction with the accompanying drawings, the present invention is further detailed explanation:
Fig. 1 is the control flow synoptic diagram that VAT invoice of the present invention is made out an invoice, authenticated.
Fig. 2 is the synoptic diagram of the information of making out an invoice at the transport process of the enterprise of paying taxes-ISDN(Integrated Service Digital Network)-tax sub-bureaus of telecommunication bureau.
Embodiment
Embodiment one: the making out an invoice of a kind of VAT invoice, authentication and querying method, with reference to Fig. 2, utilize the local telecommunication net that the enterprise of paying taxes of tax sub-bureaus and its administration is coupled together, thereby realize corporation tax managing bill (make out an invoice, check) networking, electronization, robotization.
This programme implementation process can be divided into: registration is declared by the enterprise of paying taxes; Application invoice issuing credit number; Open processes such as invoice.The enterprise of wherein paying taxes removes and to declare register request and send someone to be responsible for tax sub-bureaus and check in, get tax-card and buy outside the tax information terminal, all the other are a large amount of frequent draws a bill, checks that work such as invoice all can pass through telecommunications network---the tax control management platform is finished.The process of utilizing telecommunications network to draw a bill is actually and requires to pay taxes enterprise when the purchaser draws a bill, and the relevant information on the invoice is stored on its tax control management platform of being responsible for tax sub-bureaus.
The action of above-mentioned three processes is described in detail as follows:
Registration is declared to tax sub-bureaus by the enterprise of paying taxes: the tax bureau works out the enterprise code of paying taxes of this enterprise of paying taxes, and (general taxpayer enterprise has all had, can continue to use), paying taxes enterprise when the tax bureau registers, the used telephone wire number of tax information terminal is declared to tax sub-bureaus from now on, the publicly-owned key modes of The data such as the enterprise code of relevant this enterprise of paying taxes and enterprise operation authority are encrypted by tax sub-bureaus, write tax-card, issue enterprise then.Pay taxes enterprise to tax bureau's purchase tax information terminal.The tax information terminal is connected by the database in the tax control management platform of local telecommunications network and tax sub-bureaus.
Application invoice credit number: when the enterprise of paying taxes draws a bill, at first tax-card is inserted the tax information terminal, the tax information terminal is combined into the request of making out an invoice that a piece of news sends one or more application invoice credit number by the local telecommunication net to tax control management platform orientation with key data on the tax-card and the request of making out an invoice, and the tax control management platform is according to key data and rear side phone number identification and confirm to pay taxes the identity of enterprise and the legitimacy of authority.The tax control management platform is opened the database that is used to deposit this corporation tax invoice total data of paying taxes to legitimate enterprise, take out current invoice credit number, send to the tax information terminal, simultaneously, the subtask state table is moved to the invoice data state that waits, and a timer picks up counting.General this process must be finished the several seconds.The credit number that allows to open invoice that enterprise receives just after the several seconds that tax sub-bureaus' tax control management platform is sent of paying taxes.The identity of enterprise is not identified if pay taxes, just can demonstrate the printed words of ' your identity is not identified, and system's refusal is made out an invoice ' on the screen of tax information terminal.
Open invoice: just can make out an invoice behind the enterprise's receipt of invoice credit number of paying taxes.On the tax information terminal, the invoice electronics masterplate that the invoice credit number is arranged is filled in the invoice content, fill in errorless in inspection, when pressing " affirmation " key, the tax information terminal is beamed back the tax control management platform with invoice credit number, invoice content, the tax control management platform is found the database of this enterprise's correspondence according to the invoice credit number, reach the subtask state table, the content of invoice credit number and invoice ' is sat in the right seat ' deposits database in.Next, the tax control management platform if the invoice credit number that sends is all regained, is then turned off the invoice credit number comparison of the invoice credit number that sends out and file with database.If all do not regain, whether then then check timer, if then, then abolish the invoice credit number of providing, closing database.Otherwise, continue to wait.The corresponding credit number of invoice, if in the time of need opening many invoices in the identical time, can once apply for many invoices, unnecessary remove (' returning ' message sends to the tax control management platform, and it is similar that the response of tax control management platform and overtime prompting do not have response process) by ' returning ' key.Generally begin to calculate the drawer of enterprise and 5 minutes no operation timing are arranged by ' affirmation ' or ' returning ' key from the arrival of invoice credit number, exceeding this time tax control management platform will send information ' system will arrive in limited time, whether continuation is operated ', if there is not response, system will remove aforesaid operations automatically, regain credit number simultaneously.
The data structure of invoice credit number comprises: title, tax sub-bureaus' tax control management platform telecommunication port number, tax sub-bureaus' code, enterprise code, invoice serial number field.
The uniqueness of invoice credit number: the uniqueness of tax sub-bureaus' code, enterprise code, invoice serial number can guarantee the authority of online enquiries.
Another purposes of invoice credit number is to be used to inquire about the invoice information database.
Declare dutiable goods and examine tax, the deduction link: for the enterprise of paying taxes, requirement can reflect its marketing situation, payment of tax in accordance with the law truly.Then to supervise enterprise marketing, the activity of paying taxes for the tax bureau; Check enterprise's illegal activities such as false invoice.This programme adopts telecommunications network to make out an invoice in real time, make out an invoice and the data on the invoice have been deposited into the database of being responsible in tax sub-bureaus' tax control management platform when confirming, the data query that the notice of nuclear tax work is forwarded to Relational database from invoice anticounterfeiting with check the generation of getting rid of false invoice from the source.Significantly reduce the workload of declaring dutiable goods and examining tax, deduction link.But the work of this link is still very important.In the primary stage of scheme implementation, the making out an invoice of VAT invoice of new generation, authentication only are used for the VAT invoice management with querying method and information management system thereof, to declaring dutiable goods of some non-VAT invoice of enterprise, also will finish in this link.The tax control management platform is according to the tax information of enterprise, every month regularly statistics produce the electronic taxation table of enterprise, the data archiving that the electronic taxation table is counted, the comparison foundation of declaring dutiable goods as enterprise.At the end of month, the enterprise of paying taxes is sent to the tax bureau with the electronic data tax report table, and this tax report table content comprises: month sales volume; VAT invoice total value, the total value of paying taxes, invoice schedule (annex); Small amount invoice gross, the total value of paying taxes, invoice schedule (annex); Crime of illegally handling the issuance of invoices offset of tax payment on tax rebate on exports total value, invoice offsetting slip inventory (month electronic taxation table must be imported the credit number of each electronic invoice offsetting slip when filling in, be convenient to revenue department and utilize network to check automatically).By verifying statistics the end of month, the tax bureau analyzes enterprise's marketing situation, invoice issuing situation, finds out the in-problem enterprise of paying taxes.Adopt restriction enterprise to open the scope of the listed business kind of VAT invoice and open the method for invoiced amount, take precautions against and stop enterprise by the illegal profit of ' voiding ' VAT invoice.The situation of making out an invoice of enterprise will be monitored, be added up to " management monitoring system " in the tax control management platform at any time, to the actual amount and the new account enterprise that quantity differs greatly and the amount of making out an invoice is bigger of making out an invoice of paying taxes, show alerting signal, submit tax control managerial personnel's attention to.To ' make a false report the taxpayer ' and gain VAT invoice by cheating, the criminal offence of peddling ' empty ticket ' is restricted to minimum degree.
Invoice data inquiry: also provide the path of inquiring about invoice database by the person in charge tax sub-bureaus of purchase enterprise or purchase enterprise according to the credit number on the invoice among the figure.The inquiry of database can by ISDN telecommunications network or national tax management information system level Four backbone network, be adopted manual or inquiry automatically by the person in charge tax sub-bureaus of purchasing unit or purchasing unit according to the credit number on the invoice.The method of inquiry is very simple, and the user with the input of the ticket number on the invoice, then by ' affirmation ' key, can receive the full detail of this invoice by the query interface of tax information terminal.After system popularizes, only need inquiry to have or not credit number, can judge the true and false of invoice.Tax bureau's inquiry is generally carried out when examining tax the end of month, also can inquire about at any time as required.By the agency of is paid taxes enterprise when electronic invoice is filled in application above, and the tax control management platform is confirming to send ticket number after the identity, and the tax control management platform can gather this number the back to relevant tax bureau data base querying.The input of invoice credit number also is to use the keyboard input generally speaking.Under the bigger situation of workload, can use bar codes technique, to solve the problem that the quick import duty keyholed back plate of offsetting slip invoice credit number pats the platform database.
Provide out the control flow of an invoice among Fig. 1, if the taxpayer once needs application when opening many invoices, system can satisfy by authority requirements apply for that the invoice issuing flow process is constant.
Being kept at the database of being responsible on tax sub-bureaus' tax control management platform, is one of the present invention program very part and parcel.It will be foundation according to the data that leave in this database that the corporate tax people pays taxes, examines business such as tax, deduction.Therefore, the safety of this database is most important.This programme guarantees the safety of the database in the tax control management platform in the following way:
The read/write properties of this database is defined as:
Write: enterprise's key authority (revenue department do not have make out an invoice and related data write authority).
Revise: revenue department's the two poles of the earth key authority enters simultaneously can revise (being used for situations such as emergency measure or irresistible the condition of a disaster generation).
Read: no key.
Digital certificate: in the secret and safe measure, use digital certificate proof user's identity.To the pay taxes number combination of the telephone wire that the proprietary key of enterprise and tax information terminal use of the present invention program is a digital certificate, is used to prove the pay taxes identity and the authority of enterprise.
The tax control management platform will be paid taxes the key of the public close and secret of the The data of enterprise to encryption method, and the tax bureau keeps private cipher key.
The pay taxes digital certificate of legitimacy of the identity of enterprise and authority of recognition and verification is set, and the data structure of digital certificate comprises title, enterprise name, enterprise code, access rights code, tax sub-bureaus' tax control management platform telecommunication port number field.
The key of digital signature is to confirm this signature by the enterprise oneself transmission of paying taxes, and till send to reception, revises without anyone.Adopting the real-time point-to-point transmission short message of telecommunications network is to guarantee above-mentioned two the most effective means of key problem in technology.Because the tax control management platform that real-time point-to-point connection is actually pay taxes enterprise and tax sub-bureaus links together ' transparent ', this moment, telecommunications network only was equivalent to a transmission lines, with the data in real time of the enterprise of paying taxes send the tax control management platform to.During transmitting, can't revise wherein data.In addition, adopt the short message of regular length to send from transmitting data structure.Transmit a Frame and only use 128ms.Key and invoice information data all adopt this Frame to finish.Do like this, guaranteed that equally anyone can't intercept and capture or revise data wherein during transmitting.
The verifying SMS that adopts telecommunications network to connect in real time, thus guarantee that the authenticity of the data person of signing and issuing identity and data can not change till receiving from sending to, and realize digital signature.
The realization of key: key is made up of public keys and private cipher key, and when encrypt using, addressee is open with public keys, allows addresser that information is issued him after with public-key encryption.Information is in case after encrypting, have only addressee just can untie with one's own private cipher key.Publicly-owned key and private cipher key are to occur in pairs.The present invention program's key link is that The data passwords such as the identity of the enterprise of paying taxes on the tax-card (enterprise code), authority are write, and the tax bureau is defined as the receiving party, and the enterprise defining of paying taxes is an information sender.At first, to the pay taxes publicly-owned secret key encryption of The data of enterprise of the tax bureau, and this password write on issue the enterprise of paying taxes on the tax-card, the tax bureau keeps private cipher key, the enterprise of paying taxes is making out an invoice when needing, the data of being reported during application invoice credit number such as enterprise identity have only the private cipher key on tax sub-bureaus' tax control management platform to open.Thereby the confidentiality of the data on the assurance tax-card and security.The management of public keys and private cipher key should be responsible for by the specialized agency of provinces and cities and two-stage unit of person in charge tax sub-bureaus, though there is private cipher key in tax sub-bureaus, any data on the invoice also can't be imported or revise to the tax-card of the enterprise of not paying taxes and telephone number.Tax sub-bureaus run into special circumstances need revise data, and the key of upper level tax pipe department also must be arranged, and might enter into the relevant data storehouse just now and carry out data modification.
Key and deposit relation between the database of invoice data: in fact on the tax control management platform of tax sub-bureaus, all there is a proprietary invoice database in each enterprise of paying taxes.When the enterprise of paying taxes need draw a bill, tax control management platform private cipher key was opened the identity and the permissions data of the enterprise of paying taxes, and is opened the proprietary database that belongs to this enterprise according to these data, the input data.The key of each enterprise can only be opened one's own database, the input invoice information.Invoice database on tax sub-bureaus' tax control management platform is to be gathered by the proprietary database of many enterprises to form.Figuratively speaking, the database on tax sub-bureaus' tax control management platform cans be compared to the safety cabinet that bank is used to deposit user's valuables, and the unlatching of cabinet door can only be with the key in each user's hand, and bank haves no right to do so in the ordinary course of things.
The reading of invoice database on the tax control management platform is because just be used for inquiry, so need not any encryption measures.
Distributing real-time data bank: be national relatively tax management information system.The managing bill information of enterprise of will paying taxes this programme leaves in respectively on each tax control management platform of being responsible for tax sub-bureaus.The tax control management information base of each tax sub-bureaus is only deposited the data message relevant with the enterprise of paying taxes of its administration, and these information do not concentrate in the database of national tax management information system.Therefore, be defined as distributing real-time data bank.On the other hand, the invoice information database of the enterprise of paying taxes is the exclusive database of enterprise of paying taxes, and the exclusive database of enterprise of respectively paying taxes is separate, no any contact between them.Invoice information database on tax sub-bureaus' tax control management platform, just their set.Though they leave same storage space in physically, their visit is separate.Do a plurality of ports of being more convenient for like this and visit simultaneously this database concomitantly.
Distributing real-time data bank is with client's (tax information terminal; Tax bureau's audit system) the terminal/server mode designs, and it has the server of one or more multi-process, supports the request of data of a plurality of client terminals.Distributing real-time data bank is the core of data base management system (DBMS), and it constantly receives the request of access from the high level data storehouse of a plurality of client terminals.All these requests all are the form turnover with bag.Distributing real-time data bank has two kinds of dissimilar bags: call out bag and return bag.In fact calling wraps in the client generation is exactly a db transaction, and it comprises all information of accessing database; Returning bag is the response that the distributing real-time data bank in the tax control management platform is visited client terminal.Accessing database has two kinds of purposes: a kind of is reading of data, returns bag the data of client terminal requirement are sent to client terminal; Another kind is the input data, returns bag the result of input operation is sent to client terminal.Because the data input is limited by key, the access right in notebook data storehouse solves the access rights problem by the key handling module, and every client terminal that has requirement to write all is required to be the client terminal that writes authority.So herein, just there is no need to discuss the deciphering problem.
About the timeliness problem: this problem has two aspects to consider, is the database access estimation of working time on the one hand; Be the validity of working time on the other hand.
As the data base management system (DBMS) that can handle the concurrent visit of a plurality of client terminals, for guaranteeing reliable real-time visit, client terminal must limit if having time to access of database, must finish read-write operation in the time of appointment.Exceed no operation timing scope, system will remove this task.
A main target of real-time dataBase system is exactly to reduce the issued transaction of overtime restriction as much as possible, and scheduling decision relies on the attribute of affairs as much as possible, as: right of priority; In the time limit etc., reach this order ground.In most scheduling strategies, be a value that is difficult to acquisition working time, and it is very important will applying to working time in the scheduling decision.If dispatching process has obtained the relevant information of transaction time, and these information which can detect is near the affairs in time limit, so, just can give these affairs highest priorities, perhaps with those can overstepping the time limit affairs hang up.This is to the real-time of database access, and the efficient of system's operation all has important effect.
System is described below the processing procedure in time limit: in case order is sent on the server, will enter dispatching process.Dispatching process can come detection system whether can reach the time limit requirement of regulation by estimation technique working time.If the time limit requirement is feasible, the server of distributing real-time data bank will produce a distributing real-time data bank visit process, goes to carry out these affairs; Otherwise, if the time limit requirement is infeasible, will not produce this process on the server, simultaneously, client terminal is also with notified: after the distributing real-time data bank process is handled and estimated affairs this working time, will go back calling out the bag forwarding.
Client terminal must limit if having time to access of database, must finish read-write operation in the time of appointment.Exceed no operation timing scope, system will remove this task, for follow-up work is prepared.
Invoice credit number Time Of Release: in case the invoice information database is opened, in the regular hour, also do not write data (not having operation), will be regarded as invalid invoice credit number.
Also be not only estimation for the consideration of real-time data base to working time.Other any temporal information associated with the data also is crucial in real-time dataBase system.As the time of invoice credit number granting, the time that invoice is left etc.As: invoice credit number Time Of Release, invoice are left time or the like will be recorded in the case as the main foundation of invoice serial number.
The visit of distributing real-time data bank: as a distributed data base, client terminal can send order (data) and go to operate these teledatas (input of invoice data or the remote inquiry of database).As the server of a preprocessing process, at first can go to detect these orders (receiving data of coming or the data of separating out), and find out the kinds of relationships of handling these orders (data) by key, these relationship map are come to the relation table of database.At first, be to show the enterprise's invoice information database entry address reference table of all paying taxes, the position of handling them is finally found in the invoice information database entry address of determining that according to the enterprise's relevant information of paying taxes this enterprise of paying taxes is exclusive again.
If the tax control management platform of tax sub-bureaus adopts multiserver, or when sharing mode and manage the invoice information database by a plurality of server employing capacity, following method is adopted in the increase of server: for newly-increased server, describe the form that concerns like this for one and just set up when the server initialization.Server first operation when starting from oneself catalogue is read associated documents exactly, and they are stored in the relation table; Then, read a global address file again, this file comprises the address and the port thereof of all servers that moving.The relation list of newly-increased server meeting overseas broadcast oneself, other server will upgrade relation list separately, then, its relation list is sent to new server, and final newly-increased server just can have been accepted the request of client terminal.
In the present embodiment, the authority that writes of information database that leaves the VAT invoice of tax sub-bureaus in is to adopt password encryption.Tax sub-bureaus adopt the public keys mode with the data encryption on the tax-card.In case after encrypting, have only the private cipher key of revenue department they could be deciphered, thus the identity and the authority of the enterprise that determines to pay taxes, just above-mentioned said enterprise key authority.Utilize this key enterprise of paying taxes to open one's own invoice database and write data.After key is issued the enterprise of paying taxes, be responsible for the tax bureau and can not write or revise this database with this key.Thereby reduce the human factor of the link of making out an invoice as much as possible.The generation of thoroughly having stopped false invoice from the source that VAT invoice is made out an invoice.
Be the solution problems such as the tax-card that enterprise deposits key damages, loses, replacing of paying taxes.This programme is encrypted the The data public keys mode of tax-card, thereby, to paying taxes enterprise's hair fastener and, be placed on tax sub-bureaus and carry out the maintenance work of tax-card.
But, to the management of tax sub-bureaus' private cipher key, require to set tax sub-bureaus' key management authority (it is safer generally to be placed on above unit of office of provinces and cities), be used for key management to tax sub-bureaus.
Above-mentioned private cipher key must be strict controlled in the management of inner relevant departments of the tax bureau, but this key of periodic modification in case of necessity, to improve tax control management platform safeness of Data Bank.
The enterprise's The data of declaring dutiable goods of paying taxes among the present invention program transmits short message in real time, and set form is arranged, thereby has stopped the condition that ' hacker ' and ' virus ' propagates.
Embodiment two: in conjunction with Fig. 1 and Fig. 2, a kind of information management system that realizes the making out an invoice of VAT invoice, authentication and querying method is made up of tax information terminal, tax control management platform and ISDN ISDN(Integrated Service Digital Network).The tax information terminal comprises Short Message Service terminal, card reader, tax-card (IC), printer; The tax control management platform comprises ISDN PRI/BRI gateway, server and distributing real-time data bank, be that distributing real-time data bank is used to deposit the total data of the corporation tax invoice in its compass of competency by the UUS signaling transmission information of the D channel of ISDN(Integrated Service Digital Network) between tax information terminal and tax control management platform.
From the angle of ISDN(Integrated Service Digital Network) (ISDN), the tax information terminal is an ISDNTE1 terminal device.It joins by S/T interface and NT1 and isdn switch, realizes that the isdn user of basic rate holds function, function such as shares for the user provides I/O and corporate financial information.
