[0045] Example 1

[0046] like Figure 1 FIG. 1 is a flow chart of a batch signature method in an embodiment of the present application. The batch signature method provided in the embodiment of the present application includes the following steps:

[0047] Step S110: receiving a signature request initiated by a user, and obtaining a corresponding seal image and multiple signature documents according to the signature request.

[0048] In this embodiment, before receiving a signature request initiated by a user, the user's identity needs to be authenticated. The verification methods include but are not limited to username and password verification, biometric (such as fingerprint, face, iris, palm print, etc.) recognition, or a combination of the two to form a two-factor verification mechanism. That is, when the user logs into the account, in addition to entering the username and password, he can also perform secondary verification through biometric recognition methods such as fingerprint recognition and face recognition, thereby enhancing the security of the account.

[0049] After the verification is passed, the signature request initiated by the user is received and parsed to accurately understand the user's signature requirements, which includes the seal image and multiple signature documents that the user needs to operate, preparing for subsequent signature operations.

[0050] The authentication mechanism described above effectively prevents unauthorized users from initiating signature requests, ensuring the security of signature operations. Parsing signature requests accurately retrieves the required seal image and signature document, ensuring the accuracy of subsequent signature operations.

[0051] Step S120 : identifying the signature position in each signed document based on a preset text recognition algorithm, and obtaining at least one signature page specified by the user.

[0052] Furthermore, based on a preset text recognition algorithm, a specific signature position in each signed document, such as a signature field, a contract clause position, etc., is identified, and at least one signature page specified by the user is obtained.

[0053] In an optional embodiment, the preset text recognition algorithm includes a preset document parsing algorithm, such as Figure 2 As shown, the identifying of the signature position in each signed document based on a preset text recognition algorithm includes:

[0054] Step S121, parsing each of the signature documents using a preset document parsing algorithm to obtain a plurality of parsed signature documents;

[0055] Step S122: obtaining a preset document signature rule, identifying keyword coordinate points in each of the parsed signature documents according to the preset document signature rule, and using the keyword coordinate points as the signature position.

[0056] Understandably, when a signed document is input into a pre-set document parsing algorithm, the algorithm performs a preliminary structural analysis of the document based on its type and format, extracting information such as the document's text content, image elements, and layout. A text detection algorithm is then used to locate text areas within the document and extract their coordinates. A text recognition algorithm is then invoked to convert the image of the text area into text content and record the coordinates of each character, providing a foundation for subsequent keyword recognition and location.

[0057] Then obtain the preset document signing rules. The preset document signing rules define the layout and content rules of the signed document according to business needs and industry standards, including the position, size, shape of the seal, as well as the content, format, layout, etc. of the keywords.

[0058] Based on the keyword definitions in the preset document signature rules and combined with text recognition results, the document is searched and matched for keywords. Using string matching algorithms or semantic-based keyword extraction algorithms, the keyword's location in the document is determined and its coordinates are recorded. These coordinates are then used as the signature location.

[0059] In an optional embodiment, the preset text recognition algorithm includes a character recognition algorithm, such as Figure 3 As shown, the identifying of the signature position in each signed document based on a preset text recognition algorithm further includes:

[0060] Step S123, pre-processing each of the signed documents to obtain a plurality of pre-processed signed documents;

[0061] Step S124, using the character recognition algorithm to detect the text area in each of the pre-processed signed documents, and identifying the character content in the text area;

[0062] Step S125 , matching the character contents in each of the pre-processed signed documents according to the preset document signing rule, obtaining keyword coordinate points in each of the signed documents, and using the keyword coordinate points as the signature position.

[0063] Understandably, first, the signed document is preprocessed to improve the accuracy of subsequent text area detection and character recognition. The preprocessing operations include but are not limited to grayscale, binarization, denoising, tilt correction, etc.

[0064] The text detection function within the character recognition algorithm is then used to detect text regions within the pre-processed, signed document. Once the text regions are detected, the character recognition function within the character recognition algorithm is invoked to convert the characters within the text regions into editable text. Keywords are then searched and matched within the document based on the keyword definitions within the pre-set document signing rules and the recognized characters.

[0065] The position of the keyword in the document is determined through a string matching algorithm or a keyword extraction algorithm based on semantic understanding, and its coordinate point is recorded as the signature position.

[0066] The above steps can quickly and accurately identify the keyword coordinate points in the signed document, provide accurate location information for subsequent signing operations, reduce the time and workload of manual search and positioning of the signature position, and improve signing efficiency.

[0067] Step S130: Using the seal image, electronically sign at least one signature page in each of the signature documents.

[0068] Preferably, this embodiment provides a fine-tuning function for the seal image, including zooming in and out, adjusting the coordinate position, etc. After the user determines the seal image, he needs to undergo an identity authentication, and only after passing the authentication can the document be officially stamped.

[0069] Use the determined seal image to electronically sign at least one signature page in each signature document. If multiple users are editing the same document at the same time, all users' signature operations will be responded to.

[0070] The above steps allow users to add the same seal image to multiple documents and pages with a single operation, greatly simplifying the process. Automatically synchronizing the seal position avoids duplication and improves the efficiency of the signing process. By batch processing the seal positions, errors and omissions caused by manual operation are reduced, ensuring the security and integrity of electronic documents.

[0071] In an optional implementation, after each signing process is completed, this embodiment adds a verification mechanism to ensure that the signature position of all related documents remains consistent. Specifically, a preset document parsing algorithm is used to perform in-depth parsing of the signed document. During the parsing process, the algorithm can identify elements such as images and text in the document, accurately locate the location of the electronic seal, and extract the coordinate information of this location. The coordinate information generally includes the coordinates of the upper left and lower right corners of the seal, thereby determining the specific range of the seal on the document page. Next, it is determined whether the pixel difference between the coordinate information of the signature position in each signed document and the preset standard coordinates is within a preset error range. The preset error range is a reasonable threshold set based on actual needs and system accuracy. For example, in some scenarios with high accuracy requirements, the error range may be set to ±1 pixel. If it is within the preset error range, it means that the signature position meets the requirements, and a preview file is automatically generated to show the user the document effect after signing, facilitating the user's final confirmation before officially signing or saving. By accurately extracting the coordinate information of the signature position and performing error judgment, the position of the electronic seal signature is ensured to be accurate. Generating a preview file allows users to intuitively view the signed document, discover and correct possible problems in advance, reduce repeated operations caused by incorrect signature positioning, and improve overall work efficiency.

[0072] In an optional implementation, after each signing process is completed, a corresponding signature record will be generated, including at least one of the user, the seal image, the signature document, and the signing time, so that users and enterprises can trace the signing process and ensure the transparency and fairness of the signing behavior.

[0073] In an optional implementation, if the user changes the seal image on any signature page in any signature document (for example, moves or deletes it), the document management and processing technology is used to automatically apply the change to the corresponding seal images on all pages in all signature documents to ensure that all related documents remain consistent. After the change is completed, a detailed update log is generated immediately. The log content includes the operation time, the user who performed the change, the seal image information that was changed, the list of affected signature documents, and the comparison before and after the change, etc., to ensure the traceability of the operation. The system automatically performs batch changes to ensure that the seal images in all signature documents are updated uniformly, avoid manual omissions or errors, and ensure data consistency. The automated change process saves time and energy in manually updating multiple documents, significantly improving work efficiency.

[0074] The batch signing method provided in an embodiment of the present application receives a signature request initiated by a user and obtains a corresponding seal image and multiple signed documents based on the signature request; identifies the signature location in each signed document based on a preset text recognition algorithm and obtains at least one signature page specified by the user; and electronically signs at least one signature page in each signed document using the seal image. This application simplifies the user's process of adding seals to multiple files, effectively improving the efficiency and accuracy of the signing process and reducing errors and omissions caused by manual operations.
