Embodiment 1

[0070] figure 1 It is a schematic diagram of the main steps of the method for checking electronic bills in Embodiment 1 of the present invention. Such as figure 1 As shown, the method for checking electronic bills in the embodiment of the present invention mainly includes the following steps:

[0071] Step S101: Identify the ticket type of the electronic ticket to be checked, and according to the ticket type, obtain the ticket element, the element position and the QR code position of the electronic ticket to be checked from the stored ticket information file. The note type is included in the note name, usually at the top center of the electronic note, and has a large font that can be clearly identified, and its text information can be extracted. Based on the text information, the note type of the electronic note can be determined. The bill information file includes bill elements corresponding to electronic bills of different bill types, element positions of bill elements, an...

Embodiment 2

[0079] figure 2 It is a schematic diagram of the main flow of the method for checking electronic bills according to Embodiment 2 of the present invention. Such as figure 2 As shown, the method for checking electronic bills in the embodiment of the present invention mainly includes the following steps:

[0080] Step S201: Establish an electronic bill information database. Different types of electronic bills usually have different bill elements, element positions and QR code positions. Therefore, this step first establishes a Cartesian coordinate system for the electronic bill sample, and determines the position of the element and the position of the two-dimensional code of the bill element on the electronic bill sample; The positions of the two-dimensional codes are classified and stored in the bill information files, and the bill information files are written into the electronic bill information database.

Embodiment 3

[0100] Figure 4 It is a schematic diagram of the main flow of the method for checking electronic bills according to Embodiment 3 of the present invention. Such as Figure 4 As shown, the method for checking electronic bills in the embodiment of the present invention mainly includes the following steps:

[0101] Step S401: Receive the electronic bill to be checked, obtain the electronic signature from the electronic bill to be checked, and verify the electronic signature. An electronic signature is an electronic signature of an electronic document through cryptographic technology, and is an electronic code. Verifying the electronic signature is to verify whether the electronic bill to be verified has been tampered with.

[0102] The verification content of the electronic signature may include any one or more of the following: the data format of the electronic signature, the certificate of the signer, the signing time, the time stamp of the electronic signature, the signatur...

Abstract

The invention discloses a method and device for checking an electronic bill, electronic equipment and a computer readable medium, and relates to the technical field of artificial intelligence image recognition. A specific embodiment of the method comprises the steps of identifying a bill type of a to-be-checked electronic bill, and according to the bill type, obtaining bill elements, element positions of the bill elements and two-dimensional code positions of the to-be-checked electronic bill from a stored bill information file; according to the element position and the two-dimensional code position, intercepting a corresponding bill element image and a two-dimensional code image from the to-be-checked electronic bill, and performing image recognition on the bill element image and the two-dimensional code image; if it is determined that the two images are successfully recognized and the obtained recognition information is consistent, or one of the two images is successfully recognized, the recognition information which is successfully recognized is sent to a checking platform for checking; and obtaining a checking result returned by the checking platform, and completing the checking under the condition that the checking result indicates that the checking is successful. According to the method, invalid checking times are reduced, and checking cost is saved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence image recognition, in particular to a method, device, electronic equipment and computer-readable medium for checking electronic bills. Background technique [0002] In daily transaction activities, electronic bills (such as electronic bills for medical outpatient services, general-purpose machine-printed electronic invoices, electronic general value-added tax invoices, etc.) are widely used in various industries, and their popularity is increasing day by day. The invoice numbers of these electronic bills are uniformly coded across the country, and adopt unified anti-counterfeiting technology, which has the same effect as paper bills. After the financial personnel receive the electronic bill, they need to check it to distinguish the authenticity. [0003] At present, the inspection of electronic bills mostly adopts the method of image recognition, and the key information on the rec...
