Abstract

The invention discloses an electronic invoice inspection method and system based on an OFD format file. The method is characterized by obtaining an electronic invoice with an OFD format to be inspected; analyzing the acquired electronic invoice with the OFD format to be inspected, and obtaining invoice metadata and invoice signature information; verifying the information accuracy of the invoice metadata; and after the information accuracy of the invoice metadata is confirmed to pass verification, verifying the information accuracy of the invoice signature information to check the authenticityof the electronic invoice with the OFD format to be inspected. In the invention, an OFD file only needs to be uploaded, the inspection result of the invoice can be acquired after a few seconds and aninvoice inspection rate can reach a second level. Compared with a current tedious invoice inspection mode in which an invoice number, an invoice code, an invoice date, a price excluding tax, a verification code and other fields are manually filled, by using the method and the system of the invention, inspection efficiency and accuracy are greatly increased, and problems that invoice data is difficult to extract, an invoice is difficult to inspect and so on due to a PDF structure are solved.
