Embodiment approach

[0022] The specific implementation is as follows:

[0023] 1. Under normal circumstances, use the ADSL channel to complete the billing business.

[0024] 2. When the existing ADSL channel fails, the system scheduler automatically switches to use the 3G wireless network channel to complete the billing business.

[0025] 3. When billing cannot be realized through ADSL and 3G wireless channels, the system scheduler will automatically switch to the SMS channel to complete the billing business.

[0026] When the SMS channel is enabled to process the invoicing business, the tax control security module first generates the invoice anti-counterfeiting code, invoice number, and invoice code. The generated invoice information must be sent back to the server via SMS, and the taxpayer can generate a QR code and issue an invoice only after receiving the confirmation message sent back from the server.

[0027] Because it is necessary to interact with the server to issue tickets, this mode ...

Abstract

The invention provides a tax-controlled safety module for realizing fully-online tax invoicing, wherein an anti-counterfeiting code-generating module is adopted by the safety module for anti-counterfeiting code generation and data encryption and decryption, so that the safety, the authenticity and the integrality of related invoicing data are ensured. A clock chip is placed inside, so that the accuracy of the invoicing time is ensured; a 3G (3rd-Generation) wireless short-message module and a dispatching program are placed inside, the seamless dispatching in many online modes, such as ADSL (Asymmetric Digital Subscriber Line), 3G, short massages and the like can be realized by the dispatching program, and the 7*24-hour real-time fully-online tax invoicing is realized; and considering the seldom-occurring condition that an invoice can not be provided for a consumer due to the problem occurrence of three online invoicing passages, an off-line invoicing passage is provided by the safety module. A two-dimensional code-generating module is placed inside, so that the generation of invoice-surface two-dimensional codes is realized, and the rapid identification of a tax authority is facilitated. The identity of a taxpayer is authenticated through a CA (Certificate Authority) certificate. Generated anti-counterfeiting codes can be verified to ensure the authenticity of the invoice.

Description

technical field [0001] The invention relates to an application of computer technology in the field of financial technology, in particular to a tax control security module for realizing full online tax invoicing. [0002] The present invention relates to a tax control security module that realizes full online tax billing. Specifically, it uses relevant information technology, security authentication technology, domestic encryption and decryption algorithms, chips and clock chips, etc. to realize full online 7×24 hours on the client side. Tax control security module for invoicing. Background technique [0003] At present, under the current business processing mode of the invoice online system, various business data such as billing can only be transmitted through the ADSL broadband channel. ADSL is used as a normal network connection. During the transmission process, due to the high failure rate of various transmission media such as network side, user side equipment and lines,...
