A system and method for verifying the authenticity of invoices in real time

Abstract

The invention relates to a system and method for real-time invoice authenticity verifying. The system comprises scanners, information acquisition output modules, a server and decryption machines. Each enterprise sets a scanner and an information acquisition output module connected with the scanner; the server is respectively connected with the more than two decryption machines; the information acquisition output models are respectively connected with the server; the information acquisition output modules control the scanners to scan invoices, identify invoice images and combine invoice plaintexts and invoice ciphertexts into invoice data information for sending to the server; the server selects an idle decryption machine as a specified decryption machine for decrypting the invoice ciphertexts, determines whether invoice decryption information and the invoice plaintexts are the same, and if it is determined that the invoice decryption information and the invoice plaintexts are the same, sending the information that the invoices are true invoices to the information acquisition output modules for outputting, otherwise, sending the information that the invoices are false invoices to the information acquisition output modules for outputting. By using the system and method provided by the invention, the invoice authenticity verifying efficiency and the utilization efficiency of the decryption machines can be improved.

Description

technical field [0001] The invention relates to the technical field of invoice anti-counterfeiting, in particular to a system and method for real-time verification of the authenticity of invoices. Background technique [0002] The anti-counterfeiting of invoices has special significance for national taxation. At present, the anti-counterfeiting technology of invoices is usually carried out in an electronic form to improve the work efficiency of tax authorities and taxpayers. [0003] figure 1 It is a structural diagram of the existing system for verifying the authenticity of invoices. Such as figure 1 As shown, the information collection and output module 102 installed in each enterprise can control the connected scanner 101 to scan the invoice, and after receiving the invoice image sent by the scanner 101, the information collection and output module 102 can identify it, Send the obtained invoice plaintext, invoice ciphertext and other data to the cache 103 of the tax b...

Problems solved by technology

[0004] The prior art has the problem of low invoice authenticity verification efficiency and decryption machine utilization efficiency. This is because the server 104 periodically reads data from the cache 103 in batches, and its scheduling of the decryption machine 105 is also in accordance with the number from small to large. Large or from large to small rules, so that each information collection output module 102 can query the authenticity information of the invoice from the cache 103. is the maximum cycle for the server 104 to process a batch of data), and the invoice authenticity information can be obtained only after the invoice authenticity information is obtained, which undoubtedly reduces the invoice authenticity verification efficiency of the system

In addition, if the decryption machine 105 currently to be selected by the server 104 (referred to as the current decryption machine) has not finished processing work, even if other decryption machines 105 are idle, the server 104 still has to wait for the current decryption machine to finish working, and then process the The invoice ciphertext is sent to the current decryption machine for decryption, which further reduces the efficiency of verification of invoice authenticity in the prior art, and at the same time, the utilization efficiency of the decryption machine is relatively low
