Description

Embedded tax control computer system

Invention field

The present invention relates to computing machine tax-control anti-counterfeit system field, specifically, the present invention is a kind of embedded tax control computer system, and it is to communicate by the interface module under the different operating system platforms and host's module, thereby the data that reach between different system exchange (monitoring).

Background technology

China's fiscal revenue 90% from tax revenue.Paying tax in accordance with the law is each taxpayer's obligation.The domestic legal difference of collected amount and real collected amount of answering at present still reaches 20%～40%.According to interrelated data, national annual tax runs off 1,000 hundred million yuan at least.The taxpayer has been done " general scale taxpayer " in the new tax law of State Council's issue and " small-scale taxpayer " two classes are distinguished.Wherein " general scale taxpayer " accounting is sound, accurate tax information can be provided, it is stronger that measure is checked by the competent department of taxation, general equal can paying tax in accordance with the law, and the small-scale taxpayer is (comprising being engaged in the wholesale or retail of goods, year taxable sales volume below 1,800,000 yuan and the unsound taxpayer of accounting) can only lean on assessable to tax way tax amount settled now, leak is extremely many, the loss tax is serious.Whole nation small-scale taxpayer's quantitative proportion accounts for 80% of industrial enterprise's sum, makes the method payment of duty of this class taxpayer by " taxable sales volume * tax rate ", is the difficult problem that country reduces tax losses and needs to be resolved hurrily.Current tax source management is the management of invoice at all.Therefore, in tax implementation process, China adopts the mode of " with ticket pipe tax " to carry out.Yet, facts have proved, imperfect as yet in the tax system, under the situation that the expropriation and management means still fall behind, consciousness of paying taxes is generally lower, carry out " with ticket pipe tax " and have bigger limitation." with ticket pipe tax " is confined to the nominal value audit, and the authenticity of the economic content that nominal value reflected is difficult to control, at first, exist the economic activity of not making out an invoice in a large number in the actual life, make the seller that has the power of making out an invoice to write out falsely invoice according to the amount of money of not drawing a bill, and " with ticket pipe tax " mechanism is difficult to control to this.Therefore must utilize the invoice material object to verify jointly,, checking means center of gravity be turned to the checking of real data with the importance of invoice before changing in checking work with invoice data.

But no any identification marker of discerning on the existing invoice, just on paper, printing technology, carry out false proof, must cause enterprise's cost when using invoice too high like this, and popularizing and advanced degree of modern printing technology, cause this merely from the paper false proof technological means demonstrate its hysteresis quality and insecurity; Existing VAT invoice has had the false-proof digital sign indicating number, but its password fixes, and the safety coefficient that also seems is not high enough, and the anti-counterfeiting technology means are single, and these factors all impel invoice anticounterfeiting to innovate technically and to improve.

By the on-site inspection to the existing system of tax-supervising cash register of the national taxation bureau, we find that it has following shortcoming:

1, enterprise drops into high, and overlapping investment: existing value added tax management system needs enterprise to buy an expensive tax control machine, what its function and general computing machine do not have very big different, and present enterprise's great majority all have computer, if buy a tax control machine again, just caused overlapping investment, brought certain wasting of resources, increased resistance also for the popularization of system to enterprise;

2, developing instrument lags behind, the system upgrade difficulty: this system is based on the product of DOS environment and DOS developing instrument, and the existing operating system overwhelming majority all has been the WINDOWS Windows, developing instrument also all is visual designer, so this system has restricted the development of self on internal cause;

3, operating speed is slow, and efficient is not high: this system adopts the management of IC-card formula, and when system during to the card operation, speed is slower, influence work efficiency, and especially when invoice, original tax control cash receiving system needs the Authentication devices of special use, cost height not only, and also efficient is low.

Therefore, the applicant has invented " tax eye " system, referring to No. the 02114888.0th, the Chinese patent of the applicant application, its name is called " a kind of bill encryption anti-counterfeiting authenticating computer system and bill encryption anti-counterfeiting verification method thereof ", its adopts barcode encoding and compress technique and computer database technology, can to various bills and ticket is encrypted and fake certification.

Referring to Fig. 1, this system is made up of the two large divisions: enterprises end and tax local side, the contact between it pass through intelligent CPU card as unique information carrier.At enterprises end, the computing machine of making out an invoice, the information encryption system that in the computing machine of making out an invoice, assembles, it utilizes described encryption key and is just opening the essential information generation enciphered message of bill, and utilize described bill printer on described bill, to print described enciphered message, thereby form the bill of encrypting, and deposit the CPU card in.

But, there are now many enterprises that the business management system of oneself is all arranged, such as, because some enterprise of a variety of causes is still in the application program of using under the dos operating system, as the system of the supermarket front office cashier system overwhelming majority for exploitation under the DOS, and the supermarket very large enterprise that is trading volume in order to allow the tax eye system also can the billing system under the DOS be monitored, just must combine tax eye system and these business (cash register) system.
