[0048] Figure 4 This is a schematic diagram of another electronic document packaging device provided in an embodiment of this application. Detailed Implementation

[0049] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” as used in this application and claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to any and all possible combinations comprising one or more of the associated listed items.

[0050] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" may also be interpreted as "when," "when," or "in response to a determination."

[0051] For example, see Figure 1 The diagram shown is a detailed flowchart of an electronic document packaging method provided in an embodiment of this application. The method includes the following steps:

[0052] Step 100: Receive the electronic version file.

[0053] In this embodiment of the application, a preferred approach to receiving electronic files is to receive them via a Java interface.

[0054] In practical applications, if the interface for receiving electronic files is developed based on a JAVA interface, the generation efficiency will be higher, the cross-platform applicability will be stronger, and the user experience will be better.

[0055] Step 110: Verify the validity of the electronic document.

[0056] In this embodiment of the application, the file type of the electronic layout document is OFD (Open Fixed-layout Document), and the electronic layout document includes electronic signature data.

[0057] Therefore, in this embodiment of the application, the steps for verifying the validity of the electronic document include:

[0058] Obtain the first electronic signature data of the electronic document; determine the validity of the first electronic signature data; if the first electronic signature data is determined to be valid, then determine the validity of the electronic document.

[0059] In other words, when an electronic document is generated, it is signed using valid electronic signature data to prevent unauthorized alteration during transmission. In this embodiment, upon receiving an electronic document, its legitimacy needs to be verified, specifically the validity of the electronic signature data it contains. If the verification confirms the validity of the electronic signature data, then the electronic document is deemed valid.

[0060] Step 120: Based on the preset file hierarchy rules, encapsulate multiple verified and valid electronic format files into the preset file structure.

[0061] In this embodiment of the application, when multiple verified electronic format files are packaged into a preset file structure based on preset file hierarchy rules, a preferred implementation is to embed multiple electronic format files into a specific file structure based on preset file hierarchy rules; generate its description file and entry file according to the standard format of OPG (OpenPackage) file, and package it to generate the corresponding OPG file.

[0062] In other words, multiple OFD files can be packaged into a single multi-version OPG file based on preset file hierarchy rules. That is, based on preset storage rules for each file / its different content, each file / its different content is stored in a preset file structure.

[0063] Furthermore, in this embodiment of the application, the above-mentioned file encapsulation method may further include the following steps:

[0064] Obtain the second electronic signature data and verify its validity; if the second electronic signature data is verified to be valid, then sign the OPG file based on the second electronic signature data.

[0065] Specifically, each received OFD file carries an invoice identifier. After embedding each OFD file into a specific file structure to generate the corresponding OPG file, a second electronic signature data matching the invoice identifier can be obtained based on the invoice identifier included in each OFD file. This electronic signature data includes at least electronic seal information and digital signature information.

[0066] Next, the validity of the second electronic signature data needs to be verified. Once the validity of the second electronic signature data is confirmed, it can be used to sign the OPG file generated above.

[0067] The electronic document encapsulation method provided in this application embodiment will be described in detail below with reference to a specific application scenario (electronic voucher issuance scenario). For example, see [link to relevant documentation]. Figure 2 The diagram shown is a schematic representation of an electronic document packaging process according to an embodiment of this application. The method includes the following steps:

[0068] Step 1: The issuing end receives electronic voucher data.

[0069] Specifically, electronic voucher data includes at least invoice identifiers, which include: invoice type, invoice code, invoice number, etc.

[0070] Step 2: Select the matching electronic voucher template.

[0071] Preferably, an electronic voucher template that matches the invoicing identifier included in the electronic voucher data can be selected from the template library.

[0072] Step 3: Fill the selected template with the electronic voucher data according to certain calculation rules.

[0073] Specifically, the process involves parsing the electronic voucher template and calculating the coordinates, font, size, and alignment of the voucher data according to certain rules. The electronic voucher data is then filled into the template. These calculation rules can be understood as a series of formatting specifications established by the State Taxation Administration for electronic invoice templates, including the absolute and relative positions, alignment, line breaks, font, and size of the content on the voucher.

[0074] Step 4: Generate OFD electronic voucher A for the issuing end.

[0075] Specifically, after generating the OFD electronic voucher A at the issuing end, the OFD electronic voucher A is signed using first electronic signature data that matches the invoicing identifier included in the electronic voucher data received by the issuing end. Simultaneously, the issuing end sends the signed OFD electronic voucher A to the receiving end.

[0076] Step 5: The receiving end receives the electronic voucher data.

[0077] At the same time, the receiving end receives electronic voucher A sent by the issuing end.

[0078] Step 6: The receiving end verifies the validity of the OFD electronic signature data.

[0079] Specifically, the receiving end verifies the validity of the electronic signature data of OFD electronic credential A, and if the verification is valid, proceeds to step 7.

[0080] Step 7: Select the matching electronic voucher template.

[0081] Step 8: Fill the selected template with the electronic voucher data according to certain calculation rules.

[0082] Step 9: Generate OFD electronic credentials B for the receiving end.

[0083] Step 10: Generate an OPG type package file from A and B according to certain rules.

[0084] OFD e-credentials A and B will be packaged into an OPG type file according to certain rules.

[0085] Step 11: Obtain the matching electronic signature data.

[0086] Step 12: Verify the validity of the electronic signature data.

[0087] Step 13: Generate OPG electronic credentials containing electronic signature data.
