Please refer to fig. 2, which is a flowchart illustrating a visual signature method according to an embodiment of the present application. The specific flow shown in fig. 2 will be described in detail below.
In one embodiment, the target signing pages and the signing positions corresponding to the target signing pages can be determined according to default stamping positions.
For example, the default stamping position may be that each page of the document to be signed is a target signing page, and the lower right corner or random position of each target signing page is a signing position.
For example, the default stamping position may be that the last page of each section of the document to be signed is a target signing page, and the lower right corner or random position of each target signing page is a signing position.

Page＝document.GetPage(index)。
the specified signature page can be signed by one of the targets.
Wherein, index represents the mark of the target signing page needing to sign the electronic seal. In one example, the index may represent the page number of the target signing page that needs to sign the electronic seal, e.g., if the value of the index is 1, then it represents that the first page of the document to be signed is the target signing page.
Optionally, step 202 may include the following steps.
Step 2021, drawing a stamp picture according to the stamp pattern corresponding to the document to be signed.
Illustratively, the stamp picture can be determined according to the stamp pattern corresponding to the document to be signed. For example, a stamp picture can be drawn at a designated position in a drawing manner. For another example, the stamp image can be determined by storing the pre-stored pattern into the designated position.
Illustratively, the specified location may be a location for storing the signature object.
Step 2022, adding the stamp picture to the initial layer annotation.
Optionally, the stamp display layer may be created by Page, for example:
Annotation＝Page.CreateAnnotation()。
in this embodiment, the determined stamp picture may be added to the created initial layer Annotation dictionary Annotation ().
Step 2023, adding signature attributes to the initial layer annotation to obtain the seal layer annotation.
Exemplary signature attributes may include: a domain type and a domain index.
Step 2023 may include: and setting a type value for the type keyword of the initial layer annotation, wherein the type value is used for representing the domain type of the seal layer annotation.
In this embodiment, adding the signature attribute to the initial layer annotation may create a signature object SignatureObject as required.
Illustratively, an index of the keyword "FT" and the signature object SignatureObject may be added in the dictionary of the Annotation.
Where, FT means FieldType, which is a type of domain. FT may represent the type of data interaction with the user that the PDF supports.
Optionally, the FT data types may include: btn, Tx, Ch, Sig.
Btn denotes button fields (buttons fields), Tx denotes Text fields (Text fields), Ch denotes options fields (Choice fields), and Sig denotes Signature fields (Signature fields).
In this embodiment, the value of FT is Sig. Therefore, FT has a field of type Sig in Annotation for the constructed initial layer. The specific position of the domain added in the initial layer Annotation is recorded in the SignatureObject corresponding to the keyword "V".
In this embodiment, the created signature object SignatureObject is added in the initial layer Annotation.
In this embodiment, a position of the index added in the Annotation indication of the initial layer for recording is an indirect reference. From this location, the signature object SignatureObject can be found at the level of document.
Step 2023 may include: and setting an index value for the object index key word of the initial layer annotation.
In this embodiment, the index value may be used to represent an address of a signature object, where the signature object includes the stamp picture.
In order to facilitate operation, the stamp layer annotation can be constructed in a mode of interacting with a user through a provided operation interface.
Illustratively, step 2023 may include: providing an operation interface, loading the parameter information of the file to be signed in the operation interface, and setting the value of the parameter information according to the seal pattern so as to obtain the seal pattern layer annotation.
Optionally, the parameter information may include parameters related to Annotation.
And 203, forming an electronic seal graph at the signing position corresponding to each target signing page by using the index annotated by the seal layer so as to obtain a target signing file.
Illustratively, step 203 may comprise: and forming an electronic seal graph at the signing position corresponding to each target signing page by using the digital certificate corresponding to the file to be signed and the index of the annotation of the seal layer so as to obtain a target signing file.
In one embodiment, step 203 may include step 2031 and step 2032.
Step 2031, adding the index of the seal layer annotation to the annotation keyword corresponding to the signing position corresponding to each target signing page.
In this embodiment, the index of the seal layer annotation is used to present an electronic seal graphic on the target signing page.
A page dictionary may be included in each page of the document to be signed. Illustratively, the page dictionary may include annotation keywords therein.
In this embodiment, a corresponding index may be added to the annotation keyword, so that a seal layer may be added to a corresponding page.
In one example, the index of the stamp layer annotation is added to the annotation index list of each signed page of the PDF file.
In this embodiment, the electronic seal graphics to be presented can be presented at the signing position corresponding to the target signing page through the index of the seal layer annotation.
Step 2032, updating the signature value in the index of the seal layer annotation by using the digital certificate corresponding to the file to be signed to obtain the signature domain of the file to be signed, so as to obtain the target signed file.
In this embodiment, a seal diagram may be loaded in the target page that needs to be signed with the electronic signature by the method of step 2031.
The digital certificate may be, for example, a private key used for signing.
The step 2031 and the step 2032 can realize that the electronic seal image required to be presented is presented in each target signing page to which the electronic seal is required to be added. However, in the embodiment of the application, since the index of the signature domain is added to the page keyword corresponding to each target signing page, the whole file to be signed only needs one signature domain, and therefore, the signed size of the file to be signed can be reduced. Furthermore, because each target signing page needing signing is not required to generate a signature domain, the time for generating the electronic seal can be reduced, and the efficiency of electronic signing is improved.
In another embodiment, step 203 may comprise: updating the signature value in the seal layer annotation by using the digital certificate corresponding to the file to be signed to obtain a signature domain; and adding the index of the signature domain into the annotation keyword corresponding to the signing position corresponding to each target signing page.
In the method in the embodiment of the application, a seal layer annotation of a visible phone is constructed by combining a seal pattern, and then the electronic signature is generated by combining the seal layer annotation, so that the visualization of the electronic signature can be realized.
Furthermore, by setting a signature domain for signing the document to be signed, the signing of multiple pages in the document can be realized without creating multiple signature domains, so that the signature generation efficiency can be higher. Further, since multiple target signing pages only apply one signature domain, it may be that the volume of the last signed target document is smaller.
Further, since the signed document is subjected to signature verification, in the embodiment of the present application, the same signature domain is referred to in multiple pages of signed pages, and signature domains needing to be verified can be reduced, so that compared with a mode that one signature domain is set in each page, and multiple signature domains exist in one document, the method in the embodiment of the present application can reduce the time required for starting the target signed document, and can also reduce the file volume of the target signed document.
