Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] A bill anti-counterfeiting code generation and verification system of the present invention, as attached figure 1 As shown, it consists of an invoice issuing organization and a client. The client transmits the information of generating or verifying the invoice anti-counterfeiting code to the invoice issuing organization through the communication protocol. The invoice issuing organization generates or verifies the invoice anti-counterfeiting code, and transmits the result information through the communication protocol. For the client, the invoice issuing organization is composed of a security core, an anti-counterfeiting code generation / verification server and a WEB server, and the anti-counterfeiting code generation / verification server is electrically connected to the security core and the WEB server respectively, and the security core is calculated by the anti-c...

Abstract

This invention relates to a method for generating a bill anti-false code and checking system composed of a customer end and a service end constituting a safety kernel, an anti-false code generation/check server and WEB server, the service end is interacted with the customer end via SSL protocol. This invention adopts a method of modern cryptography to apply an operation of cryptography based on ciphered code to get a bill anti-false code to be printed on the bill surface together with the number, when checking, the service end carries out ciphered code bill number operation to generate a bill anti-false code then to contrast it with the code on the bill surface to realize the check.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a system for generating and verifying a bill anti-counterfeiting code, and a method for generating and verifying a bill anti-counterfeiting code. Background technique [0002] In order to prevent tax evasion and tax evasion, as well as the use of counterfeit bills to defraud cash, effective measures must be taken to prevent the proliferation of large quantities of counterfeit bills. It is one of the effective methods to print the anti-counterfeiting code on the face of the bill so that ordinary people can verify its authenticity conveniently and quickly. Now the common method used by the tax department is to use the anti-counterfeiting tax control system and use special anti-counterfeiting tax control equipment to print bills, requiring each enterprise that issues bills to purchase a set of dedicated tax control equipment, which is costly a...
