Specifically, fig. 1 shows a flowchart of a document authentication method provided in an embodiment of the present application, where the document authentication method may be applied to a terminal device.
The document authentication method may include:
step S101, after a file generation instruction is obtained, extracting a target file template and attribute information of preset parameters in the target file template according to a file template number represented in the file generation instruction.
In this embodiment of the application, the file generation instruction may instruct to generate a file to be confirmed. The document to be confirmed may be, for example, a legal document to be certified by signing a contract or a document requiring a plurality of parties for certification, and when applied in the financial field, the document to be confirmed may also be a contract or an analysis document including macro economic data such as currency and exchange rate, finance, stock index, financing product, future, option, bond, bank, enterprise/financial risk assessment, and the like.
In the embodiment of the present application, the file generation instruction may be acquired in various manners, for example, the file generation instruction may be received by a terminal device executing the embodiment of the present application through a preset information transmission manner; in addition, the operation may be generated by the terminal device after receiving a specific operation of the user from an application page or a web page. For example, the specific operation may be a touch operation on a specific virtual key or a pressing operation on a physical key, and the like. At this time, after the file generation instruction is acquired, the file template number related to the file generation instruction may be acquired from an application page or a web page associated with the preset file generation instruction.
Wherein the document template number associated with the document generation instruction uniquely identifies the target document template. Preset parameters can be preset in the target file template. In some cases, the preset parameters may be presented to the user in the form of a name plus a to-be-filled portion. The attribute information of the preset parameter may include one or more of a name, an identification value in the target document template, a field filling type (selection box, text box, input box, etc.), a field content length, a field content format (regular expression), a source, and the like.
The size type, the name and the like of the preset parameter can be determined according to actual needs. For example, if the target document template is used to generate a contract, the preset parameters may include one or more of the name, address, contact information, contract terms, and the like of the relevant party.
In the embodiment of the application, the target file template can be configured in advance and stored in a preset database, so that the target file template can be called quickly in an application and used for quickly generating a required file to be confirmed.
Step S102, obtaining the parameter content of each preset parameter according to the source corresponding to each preset parameter.
In this embodiment, the source corresponding to the preset parameter may be configured in the target file template in advance, or may be input by the user during the use process. Illustratively, the source may be a particular database link, a web page or terminal device local storage space, or the like.
For example, in a specific application scenario, the file generation instruction is used to generate a contract to be confirmed (i.e. a file to be confirmed) in which multiple parties participate, and in a preset database, client information of each client (e.g. each enterprise, administrator, etc.) is stored in advance, preset parameters in the target file template include client information preset parameters such as a client name, a client address, a contact way, etc., and a storage address (i.e. a source corresponding to each preset parameter) of each client information in the preset database is configured in advance.
In the application process, after the file generation instruction is obtained, the client associated with the file to be confirmed can be obtained, so that the parameter content of the preset parameter of each client information, such as the contact information, the client name, the client address and the like of the client associated with the file to be confirmed, can be obtained from the preset database according to the storage address of the client information of each client in the preset database.
It should be noted that the above examples are only illustrative and not limiting to the present embodiment.
Step S103, according to the attribute information and the parameter content of each preset parameter, filling the target file template to generate a file to be confirmed, and extracting and generating operation information, wherein the generating operation information comprises information associated with a generating process of generating the file to be confirmed.
In this embodiment of the application, the target document template after the completion of the filling may be used as the document to be confirmed. The generation operation information may be obtained in real time in the process of generating the file to be confirmed, for example, the generation operation information may be obtained in real time in a screenshot mode, a screen recording mode, a webpage extraction mode, an application information extraction mode, or the like.
For example, the generating operation information may include one or more of an initiator (such as an account issuing the file generating instruction) generating the file to be confirmed, a generating time (which may be represented by a timestamp), generating content of the file to be confirmed, a file number to be confirmed, and a related operation page. The specific storage form of the generated operation information may be determined according to an actual application scenario, and may be, for example, a screenshot of a related operation page or a document, a table, a video, and the like.
The generation operation information may be subsequently used as a certificate for the file to be confirmed to identify whether the file to be confirmed is subsequently tampered or the like.
And step S104, sending the file to be confirmed to at least one account node related to the file generation instruction.
In this embodiment of the application, at least one account node related to the file generation instruction may be determined according to information such as content of the file to be confirmed, an account associated with an initiating account initiating the file generation instruction, and/or pre-stored customer account information. For example, the account node may include a review account node, a recheck account node, a file signing account node such as a credit client/core enterprise/supervisor/core enterprise after-sale branch company, and the like. In a specific application scenario, if the document to be confirmed is a contract to be signed, the at least one account node related to the document generation instruction may include an internal audit account node (such as a department manager account node) of an initiator of the contract to be signed and account nodes of other signatory parties.
It should be noted that the files to be confirmed can be sequentially sent to at least part of account nodes according to a preset sequence, so as to implement at least part of a hierarchical auditing process; in addition, the file to be confirmed can also be sent to at least part of the account nodes in parallel, so that the part of the account nodes can process the file to be confirmed in parallel, and the processing efficiency is improved.
As shown in fig. 2, in some embodiments, the account nodes include an audit account node and a file signing account node;
the sending the file to be confirmed to at least one account node related to the file generation instruction comprises:
step S201, sequentially sending the files to be confirmed to each checking account node according to a preset checking sequence and confirmation information of a front account node corresponding to each checking account node;
and step S202, after the confirmation information of each audit account node is received in sequence, the file to be confirmed is sent to each file signing account node.
In the embodiment of the application, the audit account node can audit the file to be confirmed, and the file signing account node can sign and confirm the file to be confirmed.
For example, the audit account node may include an upper account node of an account node that initiates the file generation instruction, and the file signing account node may include an external customer account node, a supervisor account node, and the like.
In this embodiment, the to-be-confirmed file is sequentially sent to each audit account node according to a preset audit sequence and the confirmation information of the pre-account node corresponding to each audit account node, so that the audit process of the to-be-confirmed file can be realized after the confirmation information of each audit account node is obtained at one time. Further, the file to be confirmed after the auditing is completed can be sent to each file signing account node. At this time, the to-be-confirmed file after the audit is completed may be sent to each file signing account node in parallel, so that each file signing account node can process the to-be-confirmed file in parallel, thereby improving the information processing efficiency.
Step S105, if the feedback information of each account node is acquired and each feedback information meets the corresponding preset condition, the confirmation of the file to be confirmed is completed, and an evidence file containing the feedback information of each account node and the generated operation information is generated.
In the embodiment of the application, each feedback information meeting the corresponding preset condition can be determined according to the corresponding requirements, attributes and the like of each account node. For example, for a certain piece of the feedback information, the condition that the feedback information satisfies the corresponding preset condition may include: if the feedback information includes confirmation information and specific data information of the corresponding account node, it can be confirmed that the feedback information satisfies the corresponding preset condition. Of course, the preset condition may be adjusted according to a specific application scenario. It should be noted that the confirmation of the file to be confirmed can be determined according to the actual operation of the file to be confirmed. For example, if the document to be confirmed is a contract to be signed, the completion of the confirmation of the document to be confirmed may include the completion of the signing of the contract to be signed.
In the embodiment of the application, the preset conditions corresponding to different account nodes may be different.
For example, for an audit account node, if the feedback information of the audit account node includes audit confirmation information of the audit account node on the file to be confirmed, the feedback information of the audit account node may be considered to satisfy a corresponding preset condition;
for the file signing account node, the file signing account node may be an account node of an external client, so that in some specific application scenarios, a signature original text of a file to be confirmed can be signed through a USBKEY certificate to obtain a signature ciphertext, so as to ensure the security of feedback information of the account node of the external client. At this time, the feedback information may include the signature ciphertext information, corresponding USBKEY certificate verification information, signing operation information of the file signing account node, and the like, and if the USBKEY certificate verification information indicates that the USBKEY certificate is verified to be passed, and the signing operation information of the file signing account node indicates that the file signing account node confirms to sign the file to be confirmed, it may be determined that the feedback information of the file signing account node satisfies a corresponding preset condition.
The specific storage form of the evidence file can be determined according to the actual application scene, and for example, the specific storage form can include one or more of documents, tables, videos, pictures (such as screenshots of related operation pages) and the like. The evidence file comprises the feedback information and the generation operation information, so that the evidence file can comprise evidence about relevant operation processes and evidence such as signature texts, ciphertext and associated files of relevant clients, a comprehensive evidence chain can be formed, and the evidence effectiveness in subsequent testification is improved.
In some embodiments, after generating the evidence file containing the feedback information of each account node and the generation operation information, the method further includes:
and uploading the evidence file to a preset platform for storage, wherein the preset platform is a data storage platform built based on a block chain.
In the embodiment of the application, the preset platform may be a data storage platform built based on a block chain, and the like. Based on the characteristics of block chain decentralization, no tampering, whole-course trace retention and the like, the evidence file can be uploaded to a preset platform for storage, subsequent evidence obtaining can be facilitated, meanwhile, the preset platform can be used for storing the evidence file in a centralized mode, and excessive storage space occupation in the terminal equipment executing the embodiment of the application is avoided.
Step S106, the evidence file and the confirmed file to be confirmed are authenticated, and authentication credentials of the evidence file and the confirmed file to be confirmed are obtained.
In the embodiment of the present application, there are various ways to authenticate the file to be confirmed and the evidence file, and specifically, the ways may be determined according to an actual application scenario. In some cases, the to-be-confirmed file and the evidence file may be authenticated by a third party authentication method with high public trust, and at this time, the to-be-confirmed file and the evidence file may be sent to a third party, and an authentication certificate fed back by the third party may be received as an authentication credential for the to-be-confirmed file and the evidence file. Of course, in some cases, the document to be confirmed and the evidence document may also be authenticated by using a custom authentication manner commonly identified by a plurality of parties according to the embodiment of the present application.
As shown in fig. 3, in some embodiments, the authenticating the evidence file and the confirmed file completed to obtain the authentication credentials about the evidence file and the confirmed file completed to include:
step S301, sending the evidence file and the confirmed file to be confirmed to an authentication platform;
step S302, receiving a digital certificate obtained after the authentication platform authenticates the evidence file and the confirmed file to be confirmed, and using the digital certificate as the authentication credential.
In this embodiment, the authentication platform may be a third party authentication platform except for the interested parties involved in steps S101 to S105. For example, the authentication platform may be a China financial authentication center (CFCA) or the like.
The specific obtaining mode of the digital certificate can be determined by the authentication platform according to actual requirements. In some embodiments, the digital certificate may be obtained by processing, by the authentication platform, the evidence file and the confirmed file to be confirmed by using various encryption algorithms.
In the embodiment of the application, after the evidence file and the confirmed file to be confirmed are obtained, the evidence file and the confirmed file to be confirmed are authenticated through the authentication platform, so that an evidence obtaining party and an evidence authenticating party are effectively separated, and authenticity and validity of relevant evidence information are guaranteed.
In some embodiments, before extracting the target file template and the attribute information of the preset parameter in the target file template according to the file template number represented in the file generation instruction, the method further includes:
and generating a file template set, wherein the file template set comprises at least one file template and file template numbers respectively corresponding to the file templates, each file template number respectively identifies each file template, and the target file template is at least one of the file templates.
In the embodiment of the application, each file template can be uniquely identified by a corresponding file template number.
In the embodiment of the application, the types of the file templates in the file template set can be determined according to actual application scenarios, and the preset parameters and the attribute information thereof in each file template can be individually set, so that flexible configuration of the file templates is realized, the applicability is good, the development efficiency is improved, repeated development is not needed, and the maintenance cost is low.
