Abstract

The invention discloses electronic invoice generation steps and a false discrimination method of the electronic invoice. The electronic invoice generation steps specifically comprise the following steps: (1) acquiring information that a user accomplishes the payment operation; (2) acquiring an organic invoice format image; (3) receiving input invoice information; (4) performing SHA-1 abstract calculation on binary data of the image so as to obtain abstract result, performing private key calculation on the abstract result so as to obtain signature data, and writing the signature data to the back side of the invoice image FF D9, thereby generating a final electronic invoice. The false discrimination method of the electronic invoice comprises the following steps: (1) reading data between FF D8 and FF D9 of the electronic invoice, and performing SHA-1 abstract calculation; (2) verifying the data of FF D9 of the electronic invoice according to the abstract data acquired in the previous step by using a public key, thereby obtaining the legality result of the data. The purposes that the resource is saved, the cost is reduced, the anti-false grade is increased, and the social development and stability are promoted can be achieved.

Description

technical field [0001] The invention specifically relates to the steps of generating an electronic invoice and its counterfeiting method. Background technique [0002] With the rapid development of Jingdong and Taobao, online shopping has become the mainstream trend of shopping, but it has brought some problems, especially paper invoices, which will inevitably lead to a huge amount of paper for traditional paper invoices, in addition to maintenance of billing equipment , management personnel and invoice storage, loss and red letter invoice management and other costs, resulting in waste of environmental resources and social resources. Therefore, the existing problem is that the existing invoices are basically printed on paper, resulting in a waste of social and environmental resources. Users hope to provide electronic invoices to reduce resource waste and save costs. Although there is also technology to provide electronic invoices in the market, electronic invoices refer to ...
