The specific implementation scheme is as follows: a file identification method, comprising: acquiring an approval file and corresponding approval information; and dynamically generating an identification image according to the approval information, and synthesizing the identification image and the approval file to obtain the identification file. Because the identification file contains the identification image which is dynamically generated according to the approval information corresponding to the approval file, the approval information corresponding to the approval file is different, and the generated identification image is possibly different. If the approval document is tampered, the content of the identification document synthesized by the identification image and the tampered approval document is changed, so that the recognition rate of the tampered content of the approval document is effectively improved. Before stamping is executed, the real-time approval of participators such as an approver and the like is not required to be agreed in advance, and the document approval efficiency is improved.
Description
Technical Field
The application relates to the field of seals, in particular to the field of file identification.
Background
The seal is a unit mark of legality and authority, and directly represents the authority, credential and responsibility. At present, large enterprise groups, government agencies and branch organizations are located all over the country, and because the organizations are numerous and have different management levels, and the unified legal system is generally adopted, the unit seal has high use frequency and high risk in the use process.
In various organizations, documents are often signed with a seal. And the document approver approves the document according to the regulations, and after the document approver passes the approval, the seal affixing person prints and affixes the approved document. However, the document is easy to be out of the monitoring range during the approval process or in the period from the approval process to the seal signing, so that the approved document can be tampered or exchanged. At present, methods for preventing the approval document from being tampered or exchanged include two methods: firstly, before a stamping person carries out stamping, an approval document is transmitted to an approver through a network communication system such as a video and the like, the approver carries out approval on the approval document in real time, and the approval document is transmitted to the stamping person for stamping in real time after an approval process is finished; and secondly, comparing the approval document with the stored electronic document so as to judge whether the manuscript is falsified. However, the first method requires a prearrangement by a participant such as a signer or an approver, which results in a long time for preparing the document approval at the early stage and a low approval efficiency. In the second method, the tampered content cannot be found quickly, resulting in long approval time and having an influence on the correctness of the seal.

Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, a schematic flow chart of a file identification method is provided, and the file identification method includes the following steps:
s110: acquiring an approval file and corresponding approval information;
s120: dynamically generating an identification image according to the approval information;
s130: and synthesizing the identification image and the approval file to obtain an identification file.
In one example, the approval documents include documents to be approved in each approval link in the approval process, and approved documents that are reviewed and confirmed by the approver to be sealed. The approval document may include a document relating to a single enterprise and a contractual (agreed upon) document for both or more parties. For example, a contract made by two or three parties, a lot document for construction of a certain province, a lot document for trade and selection of a branch department of a certain school party, a health license of a food company, an advertisement operation license, and the like.
As shown in fig. 2, the approver may upload the approval document to the document information base of the cloud storage device through the service operation device, where the service operation device may include a mobile phone, a computer, a terminal device, and the like. In the storage process, the data management platform uniformly converts the approval files submitted to the cloud storage device into files in a PDF format and corresponding approval information. The approval information includes review information of each approval stage through which the document passes and information of an approver, for example, a document number, approval time, approver identity information, etc., and a stamp name, a stamp affixing position, the number of stamps, stamp affixing time, stamp affixing place, stamp affixing performer, etc. And a file identification device in the data management platform acquires the examination and approval files and corresponding examination and approval information from the cloud storage device. And then, dynamically generating a marking image according to the approval information. On the one hand, the generated identification images are different for different approval documents. For example, for a three-party contract, the generated identification image may include the company name of the three-party company, or a company identification. For a construction land lot file of a certain province, the generated identification image may include the name of the certain province. The corresponding identification images of the two different approval documents are obviously different. On the other hand, for the same approval document, the identification images generated many times may be different. For example, in the case where the approval time is different or the identity information of the approver is different for the same approval document, the generated identification image is different. Or, the generated identification images are different under the condition that the approval person identity information is different and the corresponding seal names are different. As long as a certain factor in the approval information corresponding to the same approval document changes, the obtained identification images may be different. Furthermore, the generated identification images may be different for each single page in the same approval document. For example, for a three-party contract, the identification image in the first page may include the company name of the first party company and the company name of the second party company, the identification image in the second page may include the name of a third party company that is the name of the first party company, and the identification image in the third page may include the company identification of the third party company.
And the file identification device synthesizes the identification image and the approval file to obtain an identification file. The synthetic method can comprise the following steps: taking the identification image as a shading of the approval document; or, the identification image is arranged in a header or a footer of the approval document; or, the identification image is arranged in the blank of the upper right corner of the approval file, and the like. The synthesis mode may be set according to the actual requirements of the user, and is not specifically limited, and is within the protection scope of the present embodiment. The same dynamically generated identification image can be synthesized in each page in the approval document, and a plurality of different dynamically generated identification images can also be synthesized in each page in the approval document to obtain the identification document. The file identification device returns the identification file to the file information base, so that extraction is facilitated.
In each approval link in the approval process, the file identification device can acquire the document to be approved and corresponding approval information of the approval link from the business operation device, dynamically generate an identification image according to the approval information, and synthesize the identification image and the document to be approved to obtain an identification document. The file identification device can also acquire the approval file and corresponding approval information from the business operation device when the approval file is obtained after approval is finished and the approval file is sealed, dynamically generates an identification image according to the approval information, and synthesizes the identification image and the approval file to obtain the identification file.
In this embodiment, since the identification file includes the identification image, and the identification image is dynamically generated according to the approval information corresponding to the approval file, the approval information corresponding to the approval file is different, and the generated identification image may be different. If the approval document is tampered, the content of the identification document synthesized by the identification image and the tampered approval document is changed, so that the recognition rate of the tampered content of the approval document is effectively improved. Before the seal is executed, the real-time approval of the participants such as the approver is not required to be agreed in advance, the approver in the current approval link only needs to obtain the document to be approved obtained after the approval of the previous approval link is finished, and whether the document to be approved is falsified or not is confirmed through detecting the identification image, so that the non-real-time document approval is realized, the document approval efficiency is improved, and the time freedom is provided for the participants such as the approver.
In one embodiment, the approval information includes a document number, an approval time, and approver identification information, as shown in fig. 3, S120 includes:
s121: selecting at least one preset icon related to the approved document;
s122: dynamically generating identification image information according to the number of the types, the file numbers, the approval time and the approval person identity information of the selected preset icons, wherein the identification image information comprises the sizes, the rotation angles, the numbers and the distribution positions of the selected preset icons;
s123: and generating an identification image according to the identification image information.
In one example, the preset icon related to the approval document may include an icon in a gallery of a single enterprise or a company identifier related to a contractual (agreement) document of two or more parties, or an icon designed by a single enterprise or a company designed by two or more parties.
And inputting the independent variables such as the number of the types of the selected preset icons, the file numbers, the approval time, the identity information of the approvers and the like into a computing module, and outputting the identification image information such as the sizes, the rotation angles, the numbers, the distribution positions and the like of the selected preset icons. Because the independent variables such as the types, the file numbers, the approval time, the identity information of the approvers and the like of the preset icons are different, the obtained identification image information such as the sizes, the rotation angles, the numbers, the distribution positions and the like of the various preset icons are also different. For example, the preset icon includes a company identifier of a company A and a name of a company B, the file number is 001, the approval time is No. 1/2 in 2020, the approval person identity information includes a general manager of the company A and a financial chief of the company B, the approval person identity information is input to the calculation module, and the output identifier image information includes: the company logo of the company A is 3cm (long) × 3cm (wide), the number of the company logo is 6, the included angle between the company logo and a horizontal line is 60 degrees, the name size of the company B is 2cm (long) × 2cm (wide), the number of the company logo is 4, the included angle between the company logo and the horizontal line is 45 degrees, the distribution positions are that the company logo of the company A is distributed in the first two rows, each row is three, the icon interval is 2cm, the name of the company B is distributed in the last two rows, and the icon interval is 3 cm.
If at least one parameter of the number of the types of the selected preset icons, the file numbers, the approval time and the identity information of the approvers is different, the obtained identification image information is different. For example, the number of types, the file numbers and the identity information of the approvers of the selected preset icons are the same, the approval time is different, one is that the approval is completed at 10 points, and the other is that the approval is completed at 12 points, so that the obtained rotation angles of the selected preset icons are different, one rotation angle is 30 degrees, and the other rotation angle is 80 degrees. The identification image is dynamically generated according to the approval information, the calculation module can be set according to requirements, factors contained in the approval information and the identification image information and the corresponding relation between the approval information and the identification image information are not specifically limited, and adaptive adjustment is performed according to conditions, so that the method is within the protection range of the embodiment.
In the embodiment, the size, the rotation angle, the number, the distribution position and other identification image information of each type of preset icons are dynamically changed, so that the copying difficulty is improved, and the falsification prevention performance of the file is further improved.
In one embodiment, as shown in fig. 3, S130 includes:
s131: setting the same dynamically generated identification image as a shading in each single page of the approval document; or
S132: and taking a plurality of different dynamically generated identification images as shading, and respectively setting the shading in each single page of the approval document.
In one example, according to the number of pages of the approval document, a computing module is used for generating a corresponding identification image for each page of the document, the dynamically generated identification image is synthesized into the approval document of the electronic version, and the identification image is lined on the bottom layer of the approval document and serves as a shading of the approval document. Of course, the same identification image or different identification images may be used in each page of the document in the approval document, and the adjustment may be performed according to actual situations.
In the embodiment, the identification image in each page of the document in the approval document is dynamically changed, and the identification image is dynamically arranged in each page of the document on the basis of dynamically generating a plurality of different identification images, so that the copying difficulty is further improved, and the tamper-proof performance of the document is improved.
In one embodiment, as shown in fig. 3, the method further includes:
s140: selecting the intersection point of the identification image and the file content image in each single page in the examination and approval file, and storing the characteristic parameters corresponding to the intersection point, wherein the characteristic parameters comprise the coordinates of the intersection point, the included angle between adjacent line segments of the intersection point, and the distance from the intersection point to an end point.
