With the progress of paperless work of invoices, electronic invoices have been widely used. At present, all electronic invoices adopt a national standard format, namely an OFD format. When the electronic invoice is used for reimbursement, the validity, authenticity and the like of the electronic invoice are often required to be judged, for example, the authenticity of the electronic invoice is verified. Because the electronic invoice has the electronic signature, the electronic invoice is often verified by verifying the electronic signature of the electronic invoice.
At present, the verification operation of the electronic invoice is usually performed manually, specifically, the electronic invoice to be verified needs to be downloaded manually, the electronic invoice is checked through an OFD reader, and then the electronic signature verification information of the electronic invoice is clicked manually. The verification efficiency of the electronic invoice is low because the verification operation of the electronic invoice manually needs to be performed by fussy operation. In addition, when the electronic invoice is verified, the electronic invoice needs to be downloaded, for example, to a local storage, and this processing mode has a risk of information leakage, for example, the electronic invoice leaks out, or related invoicing information leaks out.
The chinese patent application publication No. CN109523685A discloses an electronic invoice checking method based on OFD format files, which is to acquire an electronic invoice in OFD format to be checked, analyze the acquired electronic invoice in OFD format to be checked, and acquire invoice metadata and invoice signature information; verifying the information accuracy of the invoice metadata; and after the information accuracy of the invoice issuing metadata is verified, verifying the information accuracy of the invoice signing information to check the authenticity of the electronic invoice in the OFD format to be checked.
Although the method performs the operations of obtaining and verifying the electronic invoice in an automatic manner, the method still needs to download the electronic invoice to be verified to a local memory, and the problem of leakage of the electronic invoice information still exists. In addition, because the method only verifies the authenticity of the electronic invoice, the verification result is usually directly stored in the local memory, and if the verification result of the electronic invoice needs to be used in subsequent business operations, the verification result of the electronic invoice needs to be checked from the local memory, so that the verification result of the electronic invoice cannot be shared, and the subsequent work is not facilitated. Moreover, since the scheme needs to download the electronic invoice to the local memory, when the electronic invoice in the OFD format is opened, the local computer is required to run the OFD viewer, and if the local computer is not provided with the OFD viewer, the verification work of the electronic invoice is affected, which puts requirements on software installation on the local computer, and thus the verification work of the electronic invoice is limited.

Drawings
FIG. 1 is a flow chart of an embodiment of the method of the present invention for validating OFD electronic invoice signatures.
The invention is further explained with reference to the drawings and the embodiments.
Detailed Description
The method for verifying the signature of the OFD electronic invoice is used for verifying the electronic invoice in the OFD format, such as operating an image system on a local computer and verifying the electronic invoice displayed on the image system. The local computer device is provided with a processor and a memory, the memory is stored with a computer program, and the processor realizes the OFD electronic invoice signature verification method by executing the computer program.
The embodiment of the method for verifying the OFD electronic invoice signature comprises the following steps:
the method of the embodiment is implemented by a computer program, for example, the computer program runs on a computer, the computer communicates with the image system and can send control instructions to the image system, and the image system can also transmit information to the computer. Preferably, the imaging system may be a system running on a remote server, and the local computer may communicate with the imaging system via a network.
The embodiment mainly aims at verifying the electronic invoice in the OFD format, for example, a user uploads the electronic invoice in the OFD format to be verified to an image system in advance, for example, when the user needs to make an account, the user uploads the electronic invoice in the OFD format to the image system, for example, the image system is provided with a column for inputting a link or a storage address of the electronic invoice, such as a link address input window, and the user inputs the link or the storage address of the electronic invoice through the input window.
Optionally, the link of the existing electronic invoice is stored in a two-dimensional code manner, and the imaging system may also acquire the link of the electronic invoice in a manner of scanning the two-dimensional code, acquire the electronic invoice according to the link, and store the acquired electronic invoice in a memory of the imaging system. Preferably, the imaging system further obtains basic information of each electronic invoice, such as a code of the electronic invoice, an invoicer, an invoice payer, an invoice amount, an invoice date, an invoice type, and the like, and the basic information can be used as a label of the invoice so as to facilitate retrieval and query of the invoice.
Referring to fig. 1, when the embodiment is applied to verify an electronic invoice in an OFD format, a user may send an instruction for verifying the electronic invoice in the OFD format to an image system by operating a local computer. For example, the user may input a keyword through a screening page passed by the imaging system, and select an electronic invoice that needs to be verified. After the image system acquires the information of the electronic invoice needing to be verified, the electronic invoice is inquired from the storage, the electronic invoice file is acquired, and the electronic invoice file is displayed. Because the electronic invoice is in the OFD format, the imaging system needs to analyze the OFD file, acquire a file stream, and output the file stream to the browser for display.
If the number of the electronic invoices meeting the screening condition is large, the image system can provide a plurality of electronic invoice files so that a user can select one electronic invoice needing to be verified from the plurality of electronic invoices conveniently, and the image of each electronic invoice file displayed in the situation is small. Of course, if the number of electronic invoices meeting the filtering condition is small, for example, only one electronic invoice file, the image system may display only the one electronic invoice file, in which case the image of each displayed electronic invoice file is large.
Therefore, the embodiment first executes step S1 to obtain the OFD electronic invoice file displayed by the imaging system. For example, the preview interface of the imaging system may display the OFD electronic invoice file to be verified. Preferably, the imaging system transmits the OFD electronic invoice file to the local computer using a common image format. Since the local computer may not have the OFD viewer installed, the vision system sends the OFD electronic invoice file to the local storage using a general-purpose image format, for example, using the JPG format. In this way, after receiving the OFD electronic invoice file, the local computer can display the OFD electronic invoice file without installing an OFD viewer, so that a user can conveniently view the OFD electronic invoice file.
Preferably, if the electronic invoice relates to sensitive information, when the OFD electronic invoice file is displayed, the sensitive information on the electronic invoice can be subjected to fuzzification processing, for example, the sensitive information is shielded. In this way, the user does not see the entire content on the electronic invoice. In addition, the local computer does not need to download the electronic invoice, and the whole content of the electronic invoice cannot be displayed, so that the leakage of the information of the electronic invoice can be avoided.
Then, step S2 is executed, and a robot Process Automation device (RPA) running on the local computer clicks an electronic signature in the electronic invoice file. In this embodiment, the robot process automation device may be a module implemented by a computer program, and is run on a local computer to automatically implement operations such as clicking an electronic signature, calling an image system annotation function, and the like.
In this embodiment, the electronic invoice is verified by verifying information included in the electronic signature, and therefore, the OFD electronic invoice file displayed by the imaging system needs to include an image of the electronic signature in the electronic invoice. After the local computer displays the electronic invoice file, the robot process automation equipment automatically identifies the electronic signature area in the electronic invoice through an image identification technology, and automatically executes the clicking operation of the electronic signature, namely, the operation of manually clicking the electronic signature is simulated.
Because the area of the electronic signature in the OFD electronic invoice file is small, the user can conveniently preview the electronic invoice in order to facilitate click operation, and the user can conveniently perform operations of OFD electronic invoice file amplification, movement and the like through the local computer so as to conveniently amplify the electronic signature part. Because the electronic signatures of the same type of electronic invoices are always in the same area, when the electronic invoices are verified in batches, the electronic signatures of the electronic invoices can be conveniently and quickly checked by a user, after the image system receives instructions of zooming, moving and the like of the previous electronic invoice from the user, the zooming proportion and the final stopping position of the previous electronic invoice in the previewing process are recorded, namely the final display position of the electronic invoice, and when the OFD electronic invoice file of the next electronic invoice is displayed, the electronic invoice file is displayed according to the zooming proportion and the display position of the previous electronic invoice, so that when the next electronic invoice is displayed, the position of the electronic signature of the electronic invoice is directly displayed, the electronic signature of the electronic invoice is favorably checked by the user, and the electronic signature is also favorably clicked by a robot flow automation device.
Then, step S3 is executed, and after receiving the instruction that the electronic signature is clicked, the imaging system displays the information of the electronic signature, for example, re-provides the electronic invoice file, and displays the information of the electronic signature in the newly provided OFD electronic invoice file. For example, the imaging system communicates with the invoice verification server, and when the imaging system receives an instruction that the electronic signature is clicked, the current verification information of the electronic invoice is displayed on the invoice. Preferably, the acquired electronic signature verification information includes "the file digest value is successfully verified, and the signature value is successfully verified", that is, the electronic invoice is verified.
Then, step S4 is executed, and the robot process automation device acquires the verification information in the electronic signature information in the electronic invoice file, for example, only acquires information on whether the verification was successful. Certainly, the robot process automation device may also select the verification information and perform a copy operation to form the annotation information to be input.
Then, step S5 is executed, in which the robot process automation device invokes the annotation function of the imaging system, and pastes the verification information to the input annotation input box to form the annotation information. In this embodiment, the image system itself has an annotation function, which is used to annotate the electronic file stored in the image system, for example, the annotation information is used as additional information of the electronic file. The user can annotate the electronic file as needed.
In step S5, the robot process automation device sends an instruction to the imaging system to invoke the annotation function of the image system, and the imaging system generates an annotation message for the electronic invoice, and the content of the annotation message is input by the robot process automation device. At this time, the annotation content sent by the robot process automation device to the imaging system is the verification information of the electronic invoice, that is, the information that the verification is passed or the verification is not passed.
Therefore, in the verification process of the electronic invoice in the OFD format, the electronic invoice does not need to be downloaded to a local computer, on one hand, an OFD reader does not need to be installed on the local computer, the performance requirement on the local computer is not high, on the other hand, the information leakage of the OFD electronic invoice can be avoided, and therefore the information safety in the verification process of the electronic invoice is guaranteed. In addition, the image system stores the verification information of the electronic invoice in the form of annotation, so that subsequent invoice checking and other work can be facilitated.
