This application is, however, susceptible of embodiment in many other forms than those described herein and similar modifications can be made by those skilled in the art without departing from the spirit of the application, and therefore the application is not to be limited to the specific embodiments disclosed below.
It will be understood that when an element is referred to as being "mounted" to another element, it can be directly mounted to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" and/or "as used herein includes any and all combinations of one or more of the associated listed items.
Some preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes and is not intended to limit the scope of the present application.
Fig. 1 is an exemplary flow chart of an electronic signature generation method according to some embodiments of the present application. In some embodiments, the electronic signature generation method 100 may be performed by the data processing system 300. For example, the electronic signature generation method 100 may be stored in a storage device (e.g., a self-contained memory unit or an external memory device of the data processing system 300) in the form of a program or instructions that, when executed, may implement the electronic signature generation method 100. As shown in fig. 1, the electronic signature generation method 100 may include the following operations.
Step 110, determining a target image based on the file to be signed. In some embodiments, this step may be performed by the determination module 310.
In some embodiments, the document to be signed may be an electronic version document, including but not limited to various native electronic documents directly generated by electronic devices such as computer systems, digital cameras, digital sensors, etc., and digitized electronic documents obtained by digitizing and converting paper or other conventional carrier documents, for example, by scanning. The type of file to be signed may include a text file such as generated using word processor software, a data file such as generated using data processor software, an image file such as obtained using a data acquisition device, etc. The file to be signed may exist in a plurality of file formats such as DOC, DOCX, XLS, XLSX, DBF, BMP, JPG, TIFF, GIF, PNG, CAD, TXT, PDF, OFD. The present application is not particularly limited.
In some embodiments, the target image may be derived based on characteristic data of the document to be signed. The characteristic data may be data indicating the "identity" of the document to be signed. For example, assuming that the file to be signed is a text file such as a PDF file, a top page including a title, a time of delivery, and summary content of the text file may be characteristic data of the PDF file. In some embodiments, the target image may be obtained based on the portion of the data of the document to be signed that requires the generation of an electronic signature. In general, an electronic signature may be assigned to a top page or end page of a text file, for example, directly in the middle of the top page. The image resulting from converting the first page or the last page of the text file may be the target image. The determination module 310 may perform a viable format conversion operation to determine the target image based on the characteristic data of the document to be signed.
In some embodiments, the document to be signed may comprise an archive scan document. For example, a paper file is scanned by a scanning device, and contents contained in the paper file are recognized and converted into computer characters to generate the paper file. The format of the file to be signed may be JPG, BMP, GIF, TIFF, PNG, PDF, OFD or the like. Alternatively or preferably, the file to be signed may be a PDF file. The target image determined based on the document to be signed may be a PNG image. The PNG format image file can retain information related to image quality while the file size is compressed to the limit, and can ensure minimal distortion. The display rate is fast and helps to speed up the data processing speed. It will thus be appreciated that converting a document of a different format type into a target image (e.g. PNG format image) for processing may help to improve processing efficiency when processing the document.
Step 120, obtaining element information forming a target signature to be generated on the document to be signed, and first size information of the target image. In some embodiments, this step may be performed by the acquisition module 320.
In some embodiments, the element information may be information containing specific content of the target signature. For example, assuming that the target signature is a contract signature, the element information may include several words such as a company name full name and a "contract-specific signature". For another example, assuming that the target signature is a archive signature, the element information may include necessary information such as a total number, a year, a storage period, and the like. In some embodiments, the acquisition module 320 may automatically determine the element information. For example, the determining module 310 may obtain the additional data of the file to be signed at the same time after obtaining the file to be signed. The additional data may be data indicating the nature of the document to be signed, including but not limited to source, time of production, type of document, type of signature to be given, signature related content, etc. The generation module 320 may identify the additional data to obtain the element information. In some embodiments, the element information may be input via the external. For example, by data entry means into data processing system 300. The acquisition module 320 may directly acquire the element information inputted through the external data.
In some embodiments, the document to be signed may be an archive scan document and the target signature may be a six-pane archive signature. For example, the document to be signed may be a paper file directly generated after being scanned by the scanning device and transmitted to the data processing system 300. Or transferred from the scanning device to data processing system 300 by other data transfer means, such as by an intermediate storage device, such as a removable hard disk, etc. A six-pane archive seal is a signature assigned to an archive that needs to be archived. The content contained therein may include a full number, a year, a piece number, an organization (problem), a custody period, and a number of pages. The six contents are respectively filled in a cell of the signature.
In some embodiments, the document to be signed may comprise an office automation electronic document and the target signature may be a six-pane archive signature. For example, various institutions, organizations, etc. use electronic documents produced by office automation systems in daily offices. Such as with respect to certain decisions, certain measures, etc. These electronic files also require collection of archives. It may be given a six-grid archive chapter.
In some embodiments, the first size information of the target image may include an image width and an image height in pixels. That is, the first size information may be a resolution (dpi) of the target image. For example, the first size information of the target image may be represented as 320×240. That is, the pixel height of the target image is 320 pixels and the pixel width is 240 pixels. The generation module 320 may determine the first size information by analyzing attributes of the target image.
And step 130, generating a candidate signature on the target image at least based on the element information and the first size information of the target image. In some embodiments, this step may be performed by the generation module 330.
In some embodiments, the candidate signature may be one having the same signature content as the target signature. And typically the size of the target signature is specified. For example, the size of a six-grid archive chapter needs to be 4.5cm×1.6cm. Thus, in generating the candidate signature and/or generating the target signature in the candidate flow, the generation module 330 may determine the size of the candidate signature based on the size definition information for the target signature and the first size information. And determining that the text format includes a font size or the like according to how much content is contained in the element information. In the subsequent processing process, the target signature is generated based on the candidate signature through proportional conversion. For the content of generating the candidate signature, reference may be made to fig. 2 of the present application, and details are not repeated here.
And 140, generating the target signature on the document to be signed by utilizing the candidate signature based on the first size information of the target image and the second size information related to the document to be signed. In some embodiments, this step may be performed by the conversion module 340.
In some embodiments, the second size information related to the file to be signed may be second size information of a page for carrying the target signature. The second size information may also be expressed in terms of image height and image width as the first size information, which is the same or similar. Taking a to-be-signed file as an example of a PDF file, assuming that the resolution of the PDF file is 144/150dpi, the conversion relationship between one centimeter and a pixel may be 1 centimeter= 28.346 pixels. When the paper size to be printed is A4 (210 mm×297 mm), the second size information of the PFD may be 595.266 × 841.8762.
In some embodiments, the conversion module 340 may determine a conversion relationship of the first size information and the second size information and convert the candidate signature into the target signature based on the conversion relationship. The conversion relationship may be, for example, a size ratio (e.g., the ratio between 320×240 and 595.266 × 841.8762 mentioned above). Since the candidate signature differs from the target signature in size, the conversion module 340 may transform the size of the candidate signature based on the size ratio to generate the target signature.
It will be appreciated that when the target signature is given, this is required to be done in the blank of the document to be signed. Accordingly, the conversion module 340 may determine an information distribution area of the target page of the document to be signed when generating the target signature. The target page may be a page to which the target signature is given. For example, the front page of the file to be signed as the PDF file as in the foregoing section. The information distribution area can comprise the position and the range size of various information such as characters, pictures and the like on the target page. The conversion module 340 may identify the target page using an identification model to determine the information distribution area. The recognition model may include a neural network model including, but not limited to, R-CNN, overFeat, SPP-Net, attentionNet, fast R-CNN, fast R-CNN, OHEM, YOLO, SSD, R-FCN, YOLO v2, FPN, retinaNet, mask R-CNN, YOLO v3, refinisheDet, M2Det, and the like, or any combination thereof. The recognition model may also include models built based on recognition algorithms such as Tssaact, ABBYY FineReader, E-ask haran, aspase OCR SDK, anyDoc Software, cuneiForm, dynamsoft OCR SDK, omniPage, GOCR, and the like. The conversion module 340 may use the recognition model to recognize the target page, and then generate a frame line on the target page to frame various information such as text and pictures on the target page, so as to display the range of the information.
In some embodiments, the conversion module 340 may also obtain target size information for the target signature. The target size information may be converted from the size of the candidate signature based on the conversion relation. For example by scaling and/or expansion. The target size information may indicate a range size of the target signature. The conversion module 340 may generate the target signature outside the information distribution area of the target page based on the target size information. Illustratively, the conversion module 340 may search for a blank region outside the information distribution region that is larger than the range size of the target signature. And generating the target signature in the blank area. The generated target signature does not overlap with the information distribution area. In this way, the target signature does not affect the specific content on the document to be signed.
In some embodiments, when the document to be signed is an office automation electronic document, in order to ensure the uniqueness, authenticity and reliability of the electronic document, the conversion module 340 may further generate encrypted timestamp information for the target signature after giving it, so as to perform "identity verification" for the document to be signed. The encrypted timestamp information may be CA center based timestamp information.
In some embodiments, the location of the target signature on the document to be signed may vary. For example, the outside world may input control instructions to the data processing system 300 for adjusting the location of the target signature. According to the control instruction, the position of the target signature can be changed.
In some embodiments, after the target signature is generated on the file to be signed (the file to be signed that completes the signature at this time may be referred to as a target file), the target file may be saved for storage in a storage device of the data processing system 300 (e.g., a self-contained storage unit of the data processing system 300 or an external storage device such as a database or cloud). Can be referred to later. The target file may also be printed to generate a paper document. The target signature may be printed together after printing. And the size of the printed target signature also meets the relevant requirements.
It should be noted that the above description of the steps in fig. 1 is only for illustration and description, and does not limit the application scope of the present specification. Various modifications and changes to the steps of fig. 1 may be made by those skilled in the art under the guidance of this specification. However, such modifications and variations are still within the scope of the present description.
The electronic signature generation method disclosed by the application can efficiently and correctly generate the electronic signature on the document to be signed, reduces the labor cost and improves the efficiency and the accuracy. In addition, the processing of the electronic file can be combined with the time stamp information to ensure the authenticity and reliability of the electronic file. And the electronic signature which is endowed meets the standard requirement after printing.
Fig. 2 is an exemplary flow chart for determining candidate signatures according to some embodiments of the present application. In some embodiments, signature determination method 200 may be performed by generation module 330 of data processing system 300. As shown in fig. 2, the signature determination method 200 may include the following operations.
In step 210, signature definition information is obtained.
In some embodiments, the signature definition information may be information indicating a size of the signature. It should be appreciated that the size of each type of signature is correspondingly specified. For example, a contract chapter, a official chapter, or the like is required to be circular in size. The diameter is 4.2 cm, and the circular side width is 0.1 cm. The printing body adopts Song style character. For another example, an archive chapter such as a six-compartment archive chapter needs to be rectangular in size. The long side is 4.5 cm and the wide side is 1.6 cm. The signature definition information may be data containing the signature size information described above. In some embodiments, the signature definitions information may be pre-stored in the data processing system 300. The generation module 330 may obtain it directly.
It should be noted that the signature definition information is a definition of the size of the signature in the actual case, that is to say on a paper document. That is, after the candidate signature generated on the target image is printed as a paper document, the size of the signature formed on the paper document is required to meet the requirements of the signature defining information. Of course, after the candidate signature is converted into the target signature and then generated on the document to be signed, the size of the signature on the printed paper document also meets the requirement of the signature limiting information.
Step 220, determining a candidate frame range of the candidate signature on the target image based on the signature limiting information and the first size information of the target image.
The determination of candidate bounding box ranges is described below by way of example. The signature limiting information is taken as an example to limit the size of a six-grid filing chapter, and the first size information of the target image is 144/150 dpi. The actual length to pixel conversion ratio is 1 cm= 28.346 pixels. Therefore, when it is necessary to impart a six-grid archival chapter having a size of 4.5 cm×1.6 cm on the target image, the required pixel length and width are 4.5× 28.346 = 127.557 pixels and 1.6× 28.346 = 45.3536 pixels, respectively. The pixel range formed by the pixel length and the pixel width can be a candidate frame range of the candidate signature.
And 230, determining the candidate font specification of the element information in the candidate border range.
It will be appreciated that after the candidate bounding box range is determined, the details of the signature need to be generated within the bounding box. That is, the specific content indicated by the element information. The generating module 330 may select an appropriate font size according to the size of the candidate frame range and the content of the element information, so as to generate the specific content contained in the element information in the candidate frame range. The font specification includes fonts, font sizes, and the like. In some embodiments, the generating module 330 may first determine the thickness of the line that forms the candidate signature, and then determine the blank area within the candidate border range in combination with the candidate border range. I.e. an area capable of carrying said element information.

However, such modifications and variations are still within the scope of the present description.
FIG. 3 is an exemplary block diagram of a data processing system according to some embodiments of the present description. The data processing system may implement threshold correction of the scintillation pulse detector. As shown in fig. 3, the data processing system 800 may include a determination module 310, an acquisition module 320, a generation module 330, and a conversion module 340.
The determination module 310 may determine the target image based on the document to be signed. The document to be signed can be an electronic version document, including but not limited to various original electronic documents directly generated by electronic devices such as a computer system, a digital camera, a digital sensor and the like, and digital electronic documents obtained by digitally converting paper and other traditional carrier documents, for example, through scanning. The target image may be derived based on characteristic data of the document to be signed. In one example, the document to be signed may be a PDF document and the target image may be a PNG image.
The obtaining module 320 may obtain element information constituting a target signature to be generated on the document to be signed, and first size information of the target image. The element information may be information containing specific content of the target signature. For example, assuming that the target signature is a contract signature, the element information may include several words such as a company name full name and a "contract-specific signature". For another example, assuming that the target signature is a archive signature, the element information may include necessary information such as a total number, a year, a storage period, and the like. The acquisition module 320 may automatically determine the element information. The acquisition module 320 may also acquire the element information through an external data input.
The generation module 330 may generate a candidate signature on the target image based at least on the element information and the first size information of the target image. The generation module 330 may determine the size of the candidate signature based on the size definition information for the target signature and the first size information. And determining that the text format includes a font size or the like according to how much content is contained in the element information. In some embodiments, the generation module 330 may obtain signature definitions information. The signature definition information may be information indicating the size of the signature. The generating module 330 may determine a candidate bounding box range of the candidate signature on the target image based on the signature definition information and the first size information of the target image. And determining the candidate font specification of the element information in the candidate border range. After determining the candidate border range and the candidate font specification, the generating module 330 may generate the element information within the candidate border range according to the requirement specified by the candidate font specification, so as to complete the generation of the candidate signature.
The conversion module 340 may generate the target signature on the document to be signed using the candidate signature based on the first size information of the target image and the second size information related to the document to be signed. The conversion module 340 may determine a conversion relationship between the first size information and the second size information, and convert the candidate signature into the target signature based on the conversion relationship. The conversion module 340 may determine an information distribution area of a target page of the document to be signed when generating the target signature. The conversion module 340 may identify the target page using an identification model to determine the information distribution area. The recognition model may be a neural network model. The conversion module 340 may further obtain target size information of the target signature, and generate the target signature outside the information distribution area of the target page based on the target size information. When the document to be signed is an office automation electronic document, in order to ensure the uniqueness, authenticity and reliability of the electronic document, the conversion module 340 may further generate encrypted timestamp information for the target signature after giving it, so as to perform "identity authentication" for the document to be signed. The encrypted timestamp information may be CA center based timestamp information.
