[0002] With the increasing adoption of digital internet technology (IT), many signing services can now be performed online. Online signing requires generating a document with coordinate information. Current online signature solutions typically scan documents line by line during image recognition, ultimately generating a complete document with coordinate information. For large documents, online signing can be time-consuming and ineffective for online tagging and signing. Summary of the Invention

[0010] Sign the markup layer.

[0011] In the above implementation process, unlike the prior art, after obtaining the document to be identified, the embodiment of the present application does not generate a document with coordinate information based on the document to be identified. Instead, it obtains multiple document layers of the document to be identified; obtains business requirements, determines multiple requirement layers corresponding to the business requirements; generates a marking layer based on the multiple layers corresponding to the business requirements, and signs on the marking layer. Compared to the prior art method of obtaining documents with coordinate information based on line-by-line reading to achieve online signing, the embodiment provided by the present application does not require line-by-line document reading, solving the problem of low efficiency of line-by-line document reading in the prior art, effectively supporting online marking, editing, and signing services, and at the same time improving the speed of online signing.

[0016] The step of determining a plurality of requirement layers corresponding to the business requirements from the plurality of document layers includes:

At the same time, the tree-like data structure is searched based on the depth traversal algorithm, which can quickly obtain the required multiple requirement layers.

[0019] Furthermore, after the step of generating a markup layer according to the plurality of document layers corresponding to the business requirements, the method further includes:

[0027] A generation module is used to generate a marking layer according to the multiple requirement layers

[0028] The signature module is used to sign on the mark layer.

[0029] In the above implementation process, unlike the prior art, after obtaining the document to be identified, the embodiment of the present application does not generate a document with coordinate information based on the document to be identified. Instead, it obtains multiple document layers of the document to be identified; obtains business requirements, determines multiple requirement layers corresponding to the business requirements; generates a marking layer based on the multiple layers corresponding to the business requirements, and signs on the marking layer. Compared to the prior art method of obtaining documents with coordinate information based on line-by-line reading to achieve online signing, the embodiment provided by the present application does not require line-by-line document reading, solving the problem of low efficiency of line-by-line document reading in the prior art, effectively supporting online marking, editing, and signing services, and at the same time improving the speed of online signing.

[0030] Furthermore, the document layer includes one or more of: a text layer, a blank area layer, a signature position layer, a date layer, and an operation button layer.

[0045] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0046] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] With the increasing popularity of IT digitalization, many signing services can now be implemented online. Online signing requires generating a document with coordinate information. Current online signature solutions typically scan documents with coordinate information line by line through image recognition, ultimately generating complete text coordinates line by line. For large documents, the entire online signing process can be time-consuming and ineffective in supporting online marking and signing services. Therefore, embodiments of the present application provide a signature method, apparatus, electronic device, and computer-readable storage medium.

[0048] Example 1

[0049] See also Figure 1 , this embodiment of the application provides a signing method, including:

[0050] S1: Get the document to be identified;

[0051] In the above embodiment, the document to be identified may be a picture, a file stored in PDF format, etc.

[0052] The Portable Document Format (PDF) is a file format developed for file exchange independent of applications, operating systems, and hardware. Based on the PostScript language image model, PDF files guarantee precise color and accurate printing on any printer. This means that PDF faithfully reproduces every character, color, and image from the original document.

[0053] S2: Obtain multiple document layers of the document to be recognized;

[0054] In the above embodiment, the document layer refers to a picture containing elements such as text or graphics.

[0055] S3: Obtain business requirements;

[0056] In the above embodiment, the business requirement may be to find a signing location, etc. The signing location refers to an area corresponding to a layer that needs to be signed.

[0057] S4: Determine multiple requirement layers corresponding to business requirements in multiple document layers;

[0058] S5: Generate a marking layer based on multiple requirement layers;

[0059] S6: Sign on the markup layer.

[0060] In the above implementation process, unlike the prior art, after obtaining the document to be identified, the embodiment of the present application does not generate a document with coordinate information based on the document to be identified. Instead, it obtains multiple document layers of the document to be identified; obtains business requirements, determines multiple requirement layers corresponding to the business requirements; generates a marking layer based on the multiple layers corresponding to the business requirements, and signs on the marking layer. Compared to the prior art method of obtaining documents with coordinate information based on line-by-line reading to achieve online signing, the embodiment provided by the present application does not require line-by-line document reading, solving the problem of low efficiency of line-by-line document reading in the prior art, effectively supporting online marking, editing, and signing services, and at the same time improving the speed of online signing.

[0061] In a possible implementation, the document layer includes one or more of: a text layer, a blank area layer, a signature position layer, a date layer, and an operation button layer.

[0062] In the above implementation, there are various types of document layers. The text layer allows users to understand the content of contracts and documents. The blank area layer makes the display more obvious and convenient for users to view. The signature location layer is the location of the user's signature. The date file layer is the layer where the user signs the date. The operation button layer is the layer with operation buttons. Based on the above implementation, various markup layers can be generated.

[0063] Based on the above implementation, S5 includes: associating and overlaying multiple document layers, finding the associated area after overlaying, and outputting a markup layer.

[0064] For example, to find the signing location, it is necessary to associate the text layer, the blank layer, and the signature layer, find the associated area after the layers are superimposed, and output the marking layer.

[0065] Furthermore, after the step of obtaining multiple document layers of the document to be identified, the method further includes:

[0066] A tree data structure is used to store multiple document layers, where each node of the tree data structure is one of the multiple document layers;

[0067] The steps for determining multiple requirement layers corresponding to business requirements in multiple document layers include:

[0068] The tree data structure is searched based on the depth traversal algorithm to obtain multiple requirement layers.

[0069] A tree is a data structure that consists of a hierarchical set of n (n ≥ 0) nodes. It is called a tree because it resembles an upside-down tree, with its roots pointing upward and its leaves pointing downward. It has the following characteristics:

[0070] Each node has zero or more child nodes; a node without a parent node is called a root node; each non-root node has one and only one parent node; except for the root node, each child node can be divided into multiple non-intersecting subtrees.

[0071] In the above implementation, multiple document layers are stored in a tree-like data structure, which makes the storage structure of multiple document layers hierarchical and easy to search. At the same time, the tree-like data structure is searched based on the depth traversal algorithm, which can quickly obtain the required multiple requirement layers.

[0072] In a possible implementation, after the step of generating a markup layer according to multiple document layers corresponding to business requirements, the method further includes:

[0073] Removes noise features on the marker layer.

[0074] In a possible implementation, after the step of generating a markup layer according to multiple layers corresponding to business requirements, the method further includes: adjusting the position of related text in the markup layer.

[0075] Since the recognition accuracy may be low during the recognition process, resulting in the text in the layer being offset or tilted, the readability of the file can be further improved by adjusting the position of the relevant text in the markup layer.

[0076] In the above implementation process, removing interference elements on the mark layer can improve the readability of the file.

[0077] In summary, the solution provided by the embodiments of the present application can speed up the signing process. This marking process can also be applied to data collection services using optical character recognition (OCR) technology, such as quickly identifying operation blocks and information blocks in images, to provide support for rapid information parsing. OCR refers to the process by which an electronic device (such as a scanner or digital camera) examines characters printed on paper and then uses character recognition methods to translate the shapes into computer text; that is, the process of scanning text materials and then analyzing and processing the image files to obtain text and layout information.

[0082] Business requirements acquisition module 3, used to acquire business requirements;

[0083] The layer acquisition module 2 is further used to determine multiple requirement layers corresponding to the business requirements in the multiple document layers;

[0084] Generating module 4, for generating a marking layer according to multiple document layers corresponding to business requirements;

[0085] The signature module 5 is used to sign on the mark layer.

[0086] In the above implementation process, unlike the prior art, after obtaining the document to be identified, the embodiment of the present application does not generate a document with coordinate information based on the document to be identified. Instead, it obtains multiple document layers based on the document to be identified; obtains business requirements, determines multiple document layers corresponding to the business requirements; generates a marking layer based on the multiple layers corresponding to the business requirements, and signs on the marking layer. Compared to the prior art method of obtaining documents with coordinate information based on line-by-line reading to achieve online signing, the embodiment provided by the present application does not require line-by-line document reading, solving the problem of low efficiency of line-by-line document reading in the prior art, effectively supporting online marking, editing, and signing services, and at the same time improving the speed of online signing.

[0087] Furthermore, the document layer includes one or more of: a text layer, a blank area layer, a signature position layer, a date layer, and an operation button layer.

[0088] In the above implementation, there are various types of document layers. The text layer allows users to understand the content of contracts and documents. The blank area layer makes the display more obvious and convenient for users to view. The signature location layer is the location of the user's signature. The date file layer is the layer where the user signs the date. The operation button layer is the layer with operation buttons.

[0090] The layer acquisition module 2 is further used to search the tree data structure based on a depth traversal algorithm to obtain multiple required layers.

[0091] In the above implementation, multiple document layers are stored in a tree-like data structure, which makes the storage structure of multiple document layers hierarchical and easy to search. At the same time, the tree-like data structure is searched based on the depth traversal algorithm, which can quickly obtain the required multiple document layers.
