[0074] The electronic receipt acquisition method, apparatus, equipment, medium, and program products provided in this application receive electronic receipt query requests sent by external devices. The electronic receipt query request includes a target account and a target time period. The target account is the account for which the electronic receipt is to be queried, and the target time period is the time period for which the query is to be performed. The electronic receipt query request is triggered by a user through a client device. Based on the electronic receipt query request, the target bank is determined, and the electronic receipt query request is sent to the target bank's front-end server. The target bank is the bank to which the target account belongs. The system receives target electronic receipt information sent by the target bank's front-end server and sends the target electronic receipt information to the external device, so that the external device sends the target electronic receipt information to the client device. The system also receives electronic receipt download requests sent by external devices and sends the electronic receipt download requests to the target bank's front-end server. Finally, the system obtains the target electronic receipt from the target bank's front-end server and sends the target electronic receipt to the external device. Because the acquisition of electronic receipts is divided into two stages—information query and file download—when receiving an electronic receipt query request from an external device, the target bank is determined based on the query request, and the request is sent to the target bank's front-end server. The electronic receipt query request includes the target account and target time period. The target account is the account for which the electronic receipt is to be queried, and the target time period is the time period to be queried. The electronic receipt query request is triggered by the user through the client device. The target bank is the bank to which the target account belongs. Further, the target electronic receipt information is received from the target bank's front-end server and sent to the external device, which then forwards the target electronic receipt information to the client device. After the user makes a selection, the client device triggers an electronic receipt download request, which is then sent to the external device. This download request includes the identifier information of the electronic receipt to be downloaded. Then, it receives electronic receipt download requests from external devices and forwards these requests to the target bank's front-end server. It then retrieves the target electronic receipt from the target bank's front-end server and sends it back to the external devices. Compared to each enterprise establishing a separate connection with each bank, this approach divides the interaction between the client and the bank system into a layered architecture of client, external devices, multi-bank routing devices, and bank front-end servers. The multi-bank routing devices handle multi-bank receipt requests uniformly, enabling a single connection for multiple banks and unifying the acquisition of electronic receipts. Furthermore, by querying first and then initiating targeted downloads based on the query results, it avoids invalid file transfers. Attached Figure Description

[0084] The collection, storage, use, processing, transmission, provision, and disclosure of financial data or user data involved in the technical solution of this application all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0085] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0086] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0087] Electronic transaction receipts (ECTS) are digital transaction vouchers provided by banks, which businesses can use for financial reconciliation and other purposes. Currently, businesses typically have accounts at multiple banks, each with different interface protocols, data format requirements, and so on. To obtain ETS, integrating with multiple banks' ETS functionality requires developing separate adaptation logic for each bank, resulting in a complex integration process and a large development workload. Furthermore, banks also need to establish separate connections with each business, leading to maintenance difficulties.

[0088] To address the aforementioned technical issues, this application proposes the following technical concept: The enterprise client does not need to directly connect to multiple bank systems; it only needs to interact with multiple bank routing devices via external devices to complete the query and download of electronic receipts from all banks. Specifically, it receives electronic receipt query requests sent by external devices, determines the target bank based on the query request, and sends the electronic receipt query request to the target bank's front-end server. The electronic receipt query request includes the target account and target time period. The target account is the account for which the electronic receipt is to be queried, and the target time period is the time period to be queried. The electronic receipt query request is triggered by the user through the client device. The target bank is the bank to which the target account belongs. Then, it receives the target electronic receipt information sent by the target bank's front-end server and sends the target electronic receipt information to the external devices, enabling the external devices to send the target electronic receipt information to the client device. After the user makes a selection, the client device triggers an electronic receipt download request and sends it to the external devices. The electronic receipt download request includes the identification information of the electronic receipt to be downloaded. Furthermore, the system receives electronic receipt download requests from external devices and forwards these requests to the target bank's front-end server. It then retrieves the target electronic receipt from the target bank's front-end server and sends it back to the external devices. Users can trigger the download via their client devices, thereby improving the efficiency and compatibility of obtaining electronic receipts from multiple banks.

[0089] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0090] Figure 1 This is an application scenario diagram of the electronic receipt acquisition method applicable to the embodiments of this application, such as... Figure 1As shown. The system corresponding to the electronic receipt acquisition method in this embodiment may include: a client device 11, a server device 12, and a bank front-end machine 13. The bank front-end machine 13 includes bank front-end machine A and bank front-end machine B. Bank front-end machine A is the target bank's front-end machine. The server device includes a multi-line routing device 121 and an external connection device 122. The user triggers an electronic receipt query request through the electronic receipt interface of the client device 11, and the client device 11 sends the electronic receipt query request to the external connection device 122 in the server device 12. In response to receiving the electronic receipt query request, the external connection device 122 performs interface adaptation and sends the electronic receipt query request to the multi-line routing device 121. The multi-line routing device 121 receives the electronic receipt query request sent by the external connection device 122, determines the target bank based on the electronic receipt query request, and sends the electronic receipt query request to the target bank's front-end machine. Multi-line routing device 121 receives target electronic receipt information sent by the target bank's front-end machine and sends it to external device 122, which then forwards it to client device 11. The user identifies the electronic receipt to be downloaded based on the information and sends a download request to external device 122. External device 122, upon receiving the download request, performs interface adaptation and forwards the request to multi-line routing device 121. Multi-line routing device 121 then forwards the download request to the target bank's front-end machine, retrieves the target electronic receipt, and sends it to external device 122. The user can then download the target electronic receipt through client device 11.

[0091] Figure 2 A flowchart of an electronic receipt acquisition method provided in an embodiment of this application is shown below. Figure 2 As shown, the execution entity in this embodiment is a multi-line routing device. This multi-line routing device can be implemented through a computer program, or through a medium storing the relevant computer program, such as a USB flash drive and / or optical disc; alternatively, it can be implemented through a physical device that integrates or installs the relevant computer program, such as a chip or electronic device. The electronic receipt acquisition method provided in this embodiment includes the following steps:

[0092] S201, Receive electronic receipt query request sent by external device.

[0093] The electronic receipt query request includes the target account and the target time period. The target account is the account for which the electronic receipt is to be queried, and the target time period is the time period for which the query is to be performed. The electronic receipt query request is triggered by the user through the client device.

[0094] Specifically, in this embodiment, an electronic receipt query request sent by an external device is received.

[0095] As an optional implementation, based on the above embodiments, the electronic receipt query request and electronic receipt download request sent by the external device are encrypted requests;

[0096] After receiving the electronic receipt query request from the external device, it also includes:

[0097] The electronic receipt query request is decrypted using a preset decryption algorithm to obtain the decrypted electronic receipt query request.

[0098] After receiving the electronic receipt download request from the external device, it also includes:

[0099] The electronic receipt download request is decrypted using a preset decryption algorithm to obtain the decrypted electronic receipt download request.

[0100] Specifically, in this embodiment, the user triggers an electronic receipt query request by inputting a target account and a target time period through a client device. The client device sends the electronic receipt query request to an external device, which encrypts the electronic receipt query request using a preset encryption algorithm and then sends the encrypted electronic receipt query request to a multi-line routing device. Upon receiving the encrypted electronic receipt query request, the multi-line routing device decrypts the electronic receipt query request using a preset decryption algorithm to obtain the decrypted electronic receipt query request.

[0101] Similarly, the user triggers an electronic receipt download request through the client device. The client device sends the electronic receipt download request to the external device, which encrypts the electronic receipt download request using a preset encryption algorithm and sends the encrypted electronic receipt download request to the multi-line routing device. After receiving the encrypted electronic receipt download request, the multi-line routing device decrypts the electronic receipt download request using a preset decryption algorithm to obtain the decrypted electronic receipt download request.

[0102] Optionally, the preset encryption algorithm and preset decryption algorithm can be symmetric block cipher algorithms, which are not limited in this embodiment.

[0103] S202: Based on the electronic receipt query request, the target bank is determined, and the electronic receipt query request is sent to the target bank's front-end machine.

[0104] The target bank is the bank to which the target account belongs.

[0105] Understandably, the target bank can be any bank.

[0106] As an optional implementation, the following steps can be used to determine the target bank based on the electronic receipt query request and send the electronic receipt query request to the target bank's front-end server, including: determining the target bank based on the target account number; adjusting the electronic receipt query request format to the target format corresponding to the target bank to obtain the target electronic receipt query request; and sending the target electronic receipt query request to the target bank's front-end server.

[0107] Among them, the target electronic receipt query request is an electronic receipt query request adjusted to the format corresponding to the target bank.

[0108] Specifically, in this embodiment, the target account is obtained, the bank to which the target account belongs is determined based on the bank identification information included in the target account, the electronic receipt request format corresponding to the target bank is read from the preset bank format configuration file, and the format of the received electronic receipt query request is converted into the target format corresponding to the target bank, thereby obtaining the target electronic receipt query request. The target electronic receipt query request is then sent to the front-end machine of the target bank.

[0109] Optionally, the preset bank format configuration file includes a mapping relationship between the target bank and the corresponding request format of the target bank.

[0110] For example, assuming the electronic receipt query request is in JSON format and the target bank requires it to be in XML format, the JSON format will be converted to XML format, and the field names will be adjusted to the specifications required by the target bank.

[0111] Specifically, by accurately identifying the bank to which the target account belongs, requests are sent to the correct recipients, avoiding mis-sent or missed requests. The request format is adjusted to be compatible with the target bank, resolving the issue of inconsistent interface specifications between different bank systems and improving the compatibility between multi-bank routing devices and the front-end servers of various banks.

[0112] S203 receives the target electronic receipt information sent by the target bank's front-end machine and sends the target electronic receipt information to the external device, so that the external device sends the target electronic receipt information to the client device.

[0113] The target electronic receipt information refers to the electronic receipt records generated by the target account within the target time period, but does not include the specific electronic receipt. It includes summary information such as receipt number, transaction time, and amount.

[0114] Specifically, in this embodiment, after the multi-line routing platform obtains the target electronic receipt information from the target bank's front-end machine, the multi-line routing platform generates a response message according to a preset response message format. The response message includes the target electronic receipt information, and the response message is encrypted using a preset encryption algorithm. The encrypted response message is then sent to the external device, which decrypts the encrypted response message and sends it to the client device.

[0115] S204: Receive an electronic receipt download request sent by an external device.

[0116] The electronic receipt download request includes the identification information of the electronic receipt to be downloaded.

[0117] Specifically, in this embodiment, after receiving the target electronic receipt information, the user can select at least one electronic receipt to be downloaded through the client device, then trigger an electronic receipt download request and send it to the external device. The external device then sends the electronic receipt download request to the multi-line routing device, which receives the electronic receipt download request.

[0118] S205 sends the electronic receipt download request to the target bank's front-end server.

[0119] Specifically, in this embodiment, the multi-line routing device reads the electronic receipt request format corresponding to the target bank from a preset bank format configuration file, and converts the format of the received electronic receipt download request into the target format corresponding to the target bank, thereby obtaining the target electronic receipt download request. The target electronic receipt download request is then sent to the target bank's front-end processor.

[0120] S206: Obtain the target electronic receipt from the target bank's front-end machine and send the target electronic receipt to the external connection device.

[0121] As an optional implementation, the following steps can be used to obtain the target electronic receipt from the target bank's front-end server and send the target electronic receipt to an external device, including: determining the current server environment; obtaining the original electronic receipt from the target bank's front-end server based on the current server environment and according to a preset method; determining the user's network access type; encrypting the original electronic receipt using a preset encryption algorithm to obtain the target electronic receipt; and sending the target electronic receipt to the external device based on the user's network access type.

[0122] Specifically, the preset methods include obtaining the data via API request, secure file transfer protocol, and bank front-end server directory. If the preset method is API request, the target bank front-end server returns a file identifier and download address, and the multi-line routing device obtains the corresponding original electronic receipt via the download address. If the preset method is secure file transfer protocol, the multi-line routing device connects to the server corresponding to the secure file transfer protocol and then obtains the original electronic receipt from that server. If the preset method is bank front-end server directory, the multi-line routing device downloads the original electronic receipt from the bank front-end server directory.

[0123] The server environment includes a Windows server and a Secure File Transfer Protocol (SSL) service. If a Windows server is used, the bank's front-end server can share the electronic receipt file directory with the multi-line routing server. If the SSL service is used, the multi-line routing device downloads the original electronic receipts from the bank's front-end server directory via the SSL protocol.

[0124] Specifically, network access types include leased lines and wireless networks. If the network access type is a leased line, the decrypted target electronic receipt is uploaded to the external device via a pre-configured file server. If the network access type is a wireless network, the decrypted target electronic receipt is sent to the external device via an HTTP file stream with the transaction attached.

[0125] Optionally, the preset file server is a self-defined file server, which is not limited in this embodiment.

[0126] Specifically, in this embodiment, when the target bank's front-end server sends the response information of the target electronic receipt to the multi-line routing device, if the current server environment is a running Windows server, the original electronic receipt is retrieved from the target bank's front-end server's directory. If the current server environment is a Secure File Transfer Protocol (SLP) service, the original electronic receipt can be obtained from the target bank's front-end server via an interface request or the SLP. Further, the multi-line routing device reads the network access type of the client device and the external device. If the network access type is a leased line, the file is uploaded to the external device via a preset file server. If the network access type is a wireless network, the file is sent to the external device via an HTTP file stream with attachments. After obtaining the original electronic receipt, a preset encryption algorithm is used to encrypt the original electronic receipt to obtain the target electronic receipt. The target electronic receipt is then sent to the external device based on the user's network access type.

[0127] The electronic receipt acquisition method provided in this application includes: receiving an electronic receipt query request sent by an external device; the electronic receipt query request includes a target account and a target time period; the target account is the account of the electronic receipt to be queried, and the target time period is the time period to be queried; the electronic receipt query request is triggered by a user through a client device; determining the target bank based on the electronic receipt query request and sending the electronic receipt query request to the target bank's front-end server; the target bank is the bank to which the target account belongs; receiving the target electronic receipt information sent by the target bank's front-end server and sending the target electronic receipt information to the external device, so that the external device sends the target electronic receipt information to the client device; receiving an electronic receipt download request sent by the external device; sending the electronic receipt download request to the target bank's front-end server; obtaining the target electronic receipt from the target bank's front-end server and sending the target electronic receipt to the external device. Since the electronic receipt acquisition is split into two stages—information query and file download—when receiving the electronic receipt query request sent by the external device, the target bank is determined based on the electronic receipt query request, and the electronic receipt query request is sent to the target bank's front-end server. The electronic receipt query request includes the target account and target time period. The target account is the account for which the electronic receipt is to be queried, and the target time period is the time period for which the query is to be performed. The electronic receipt query request is triggered by the user through the client device. The target bank is the bank to which the target account belongs. Further, the system receives the target electronic receipt information sent by the target bank's front-end machine and sends it to an external device, which then forwards the target electronic receipt information to the client device. After the user makes a selection, the client device triggers an electronic receipt download request, which is then sent to the external device. This download request includes the identifier information of the electronic receipt to be downloaded. Then, it receives electronic receipt download requests from external devices and forwards these requests to the target bank's front-end server. It then retrieves the target electronic receipt from the target bank's front-end server and sends it back to the external devices. Compared to each enterprise establishing a separate connection with each bank, this approach divides the interaction between the client and the bank system into a layered architecture of client, external devices, multi-bank routing devices, and bank front-end servers. The multi-bank routing devices handle multi-bank receipt requests uniformly, enabling a single connection for multiple banks and unifying the acquisition of electronic receipts. Furthermore, by querying first and then initiating targeted downloads based on the query results, it avoids invalid file transfers.

[0128] This application provides an embodiment of an electronic receipt acquisition method. The executing entity in this embodiment is an external device. This multi-line routing device can be implemented through a computer program, or through a medium storing the relevant computer program, such as a USB flash drive and / or optical disc; alternatively, it can be implemented through a physical device integrating or installing the relevant computer program, such as a chip or electronic device. The electronic receipt acquisition method provided in this embodiment includes:

[0129] Receive electronic receipt query requests triggered by users through client devices and send the electronic receipt query requests to the multi-line routing device;

[0130] Receive the target electronic receipt information sent by the multi-line routing device and send the target electronic receipt information to the client device;

[0131] Receive electronic receipt download requests triggered by users through client devices and send the electronic receipt download requests to the multi-line routing device;

[0132] Receive the target electronic receipt sent by the multi-line routing device and send the target electronic receipt to the client device.

[0133] The client device can be a corporate financial system, but this embodiment does not limit it.

[0134] Specifically, in this embodiment, after receiving an electronic receipt query request triggered by a user through a client device, the external connection device can encrypt the electronic receipt query request using a preset encryption algorithm and send the encrypted electronic receipt query request to the multi-line routing device through a preset interface. After receiving the target electronic receipt information sent by the multi-line routing device, if the target electronic receipt information is encrypted, it is decrypted using a preset decryption algorithm and sent to the client device after the preset decryption algorithm is used. After receiving an electronic receipt download request triggered by a user through a client device, the external connection device can encrypt the electronic receipt download request using a preset encryption algorithm and send the encrypted electronic receipt download request to the multi-line routing device through a preset interface. After receiving the target electronic receipt sent by the multi-line routing device, if the target electronic receipt is encrypted, it is decrypted using a preset decryption algorithm and sent to the client device after the preset decryption algorithm is used.

[0135] Optionally, the preset interface is a pre-defined interface used for communication between external devices and multi-row routing devices, etc. Communication can also be carried out in other ways, which are not limited in this embodiment.

[0136] Specifically, the external connection device acts as an intermediate node between the client and the multi-line routing device, uniformly receiving and forwarding query requests. This simplifies the direct interaction between the client and the multi-bank system, reduces the complexity of client development, and uniformly forwards download requests, avoiding direct communication between the client and the multi-line routing device and reducing the risk of network exposure.

[0137] As an optional implementation, based on the above embodiments, before sending the electronic receipt query request to the multi-line routing device, the method further includes:

[0138] The electronic receipt query request is encrypted using a preset encryption algorithm to obtain the encrypted electronic receipt query request;

[0139] Before sending the electronic receipt download request to the multi-line routing device, the method also includes:

[0140] The electronic receipt download request is encrypted using a preset encryption algorithm to obtain the encrypted electronic receipt download request.

[0141] Specifically, in this embodiment, before the external device sends the electronic receipt query request to the multi-line routing device, it encrypts the electronic receipt query request using a preset encryption algorithm to obtain an encrypted electronic receipt query request. Similarly, the electronic receipt download request is encrypted using the same preset encryption algorithm to obtain an encrypted electronic receipt download request.

[0142] Optionally, the preset encryption algorithm and preset decryption algorithm can be symmetric algorithms, which are not limited in this embodiment.

[0143] The electronic receipt acquisition method provided in this application encrypts the request sent by the client device, realizing "end-to-end" encryption from the client to the multi-line routing device, preventing the request from being intercepted and parsed during transmission, and further enhancing the security of data transmission.

[0144] As an optional implementation, based on the above embodiments, before sending the target electronic receipt to the client device, the method further includes:

[0145] Determine whether to enable the smart association feature;

[0146] If the user enables the intelligent association function, the preset feature extraction algorithm will be used to extract key information from the target electronic receipt in order to obtain the target receipt data.

[0147] Obtain the original transaction data corresponding to the target account; the target account is the account for which the electronic receipt is to be queried; the original transaction data includes multiple transaction records;

[0148] A pre-defined semantic model is used to determine the similarity between the target return data and each original transaction data based on the target return data and the original transaction data;

[0149] Compare the similarity score with a similarity threshold;

[0150] If the similarity is greater than the similarity threshold, the original transaction data corresponding to the similarity will be associated with the target return data to obtain the target associated data.

[0151] Send the target electronic receipt to the client device, including:

[0152] Add the target-related data to the target electronic receipt;

[0153] Send the target electronic receipt with added target-related data to the client device.

[0154] The intelligent association function is used to match the target electronic receipt with the corresponding original transaction data.

[0155] Understandably, the smart association function can be enabled or disabled by the user.

[0156] Among them, target transaction data refers to the transaction-related feature data extracted from target transaction records. Raw transaction data refers to the transaction data generated when the target account makes transactions.

[0157] Specifically, in this embodiment, the external device reads the user account's preset configuration file to determine whether the user has enabled the smart association function. If the user has not enabled the smart association function, the process directly proceeds to the receipt sending process. If the user has enabled the smart association function, a preset feature extraction algorithm is used to identify the text in the target electronic receipt, and the target electronic receipt is parsed in a structured manner, outputting structured fields as the target receipt data. The original transaction data corresponding to the target account in the target time period is read from the preset database. A preset semantic model is called to perform the same feature extraction on the original transaction data as on the target electronic receipt. The target receipt data and each corresponding feature extracted from the original transaction data are converted into semantic vectors, and the vector cosine similarity is calculated. The calculated similarity is compared with a similarity threshold. If the similarity is greater than the similarity threshold, the original transaction data corresponding to the similarity is associated with the target receipt data, thereby obtaining the target associated data.

[0158] Optionally, the preset semantic model can be a Bidirectional Encoder Representations from Transformers (BERT) model, or it can be set independently according to requirements. This embodiment does not impose any restrictions.

[0159] Optionally, the target receipt data may include transaction time, transaction amount, payee and payee accounts, transaction channel, handling fee, business type description, etc., which are not limited in this embodiment.

[0160] Optionally, the preset feature extraction algorithm can be an optical character recognition algorithm or a pre-trained neural network model; this embodiment does not impose any limitations.

[0161] Specifically, the target associated data can be the watermark information of the transaction sequence number in the original transaction data, the transaction data corresponding to the target electronic receipt, or a two-way mapping table between the receipt number of the target electronic receipt and the transaction sequence number of the corresponding original transaction data. This embodiment does not impose any limitations.

[0162] Furthermore, target-related data is added to the target electronic receipt, generating a data packet containing target-related transaction data, and the target electronic receipt with the added target-related data is sent to the client device.

[0163] The electronic receipt acquisition method provided in this application balances functional flexibility and user privacy needs by allowing users to choose whether to enable intelligent association. It employs a preset feature extraction algorithm to automatically extract key information from receipts, replacing manual data entry and improving the efficiency and accuracy of information extraction. Through threshold filtering and association binding, it ensures that only highly relevant transaction data is associated, avoiding interference from invalid information. Furthermore, embedding associated data into the receipts allows users to intuitively understand the transaction background corresponding to the receipts, reducing manual verification costs and improving financial processing efficiency.
