The file authentication method provided by the embodiment of the application can be applied to terminal equipment such as a server, a desktop computer, a mobile phone, a tablet personal computer, wearable equipment, vehicle-mounted equipment, augmented reality (augmented reality, AR)/Virtual Reality (VR) equipment, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA) and the like, and the embodiment of the application does not limit the specific type of the terminal equipment.
Specifically, fig. 1 shows a flowchart of a file authentication method provided by an embodiment of the present application, where the file authentication method may be applied to a terminal device.
The file authentication method may include:
step S101, after a file generation instruction is acquired, extracting a target file template and attribute information of preset parameters in the target file template according to the file template number characterized in the file generation instruction.
In the embodiment of the application, the file generation instruction can instruct to generate the file to be confirmed. The document to be confirmed may be a legal document to be authenticated by a contract to be signed or a document requiring authentication by a plurality of participants, and when the document to be confirmed is applied in the financial field, the document to be confirmed may also be a contract or analysis document including macroscopic economic data such as currency and exchange rate, finance, stock fingers, financial products, futures, options, bonds, banks, enterprise/financial risk assessment, and the like.
In the embodiment of the present application, there may be various ways of obtaining the file generation instruction, for example, the terminal device executing the embodiment of the present application may receive the file generation instruction through a preset information transmission manner; further, the specific operation of the user may be received from the application page or the web page by the terminal device. By way of example, the specific operation may be a touch operation on a specific virtual key or a press operation on an entity key, or 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 a file generation preset instruction.
Wherein the file template number associated with the file generation instruction may uniquely determine the target file template. The target file template may be preset with preset parameters. In some cases, the preset parameters may be presented to the user in the form of a name plus the portion to be filled. The attribute information of the preset parameters may include one or more of such as name, identification value in the target file template, field filling type (selection box, text box, input box, etc.), field content length, field content format (regular expression), source, etc.
The size type, the name and the like of the preset parameters 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 a related party name, address, contact address, and contract terms, among others.
In the embodiment of the application, the target file template can be preconfigured and stored in the preset database, so that the target file template can be quickly called in application and is used for quickly generating the 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. By way of example, the source may be a particular database link, a web page or terminal device local storage space, and so forth.
For example, in a specific application scenario, the file generation instruction is used for generating contracts to be confirmed (i.e. files to be confirmed) that are participated by multiple participants, and in a preset database, client information of each client (such as each enterprise, supervisor, etc.) is pre-stored, and preset parameters in the target file template include client information preset parameters such as client name, client address, contact information, etc., and storage addresses (i.e. sources corresponding to each preset parameter) of each client information in the preset database are pre-configured.
In the application process, after the file generation instruction is acquired, the client associated with the file to be confirmed can be acquired, so that the parameter content of the preset parameters of each client information, such as the contact mode, the client name, the client address and the like of the client associated with the file to be confirmed, is acquired 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 given by way of illustration only and are not limiting of the present embodiments.
Step S103, filling the target file template according to the attribute information and the parameter content of each preset parameter, so as to generate a file to be confirmed, and extracting generating operation information, wherein the generating operation information comprises information associated with a generating process for generating the file to be confirmed.
In the embodiment of the application, the target file template after filling is completed can be used as the file to be confirmed. The generating operation information may be obtained in real time during the process of generating the file to be confirmed, for example, the generating operation information may be obtained in real time by means of screenshot, screen recording, extracting a web page or application information, etc.
The generating operation information may include, for example, one or more of an initiator that generates the file to be confirmed (such as an account number that issues the file generating instruction), a generating time (which may be represented by a timestamp), a generating content of the file to be confirmed, a number of the file to be confirmed, and a related operation page. The specific storage form of the generated operation information can be determined according to the actual application scene, and for example, the specific storage form can be a screenshot of a related operation page or a document, a table, a video and the like.
The generated operation information can be used as a certificate of the file to be confirmed later so as to identify whether the file to be confirmed is tampered later or not.
Step S104, the file to be confirmed is sent to at least one account node related to the file generation instruction.
In the embodiment of the application, at least one account node related to the file generation instruction can be determined according to the content of the file to be confirmed, the account related to the initiating account initiating the file generation instruction, the prestored customer account information and the like. By way of example, the account nodes may include audit account nodes, review account nodes, document signing account nodes for trusted clients/core enterprises/supervisors/after-sales branch of core enterprises, 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 signers.
It should be noted that, the file to be confirmed may be sequentially sent to at least part of account nodes according to a preset sequence, so as to implement at least part of the hierarchical audit process; in addition, the file to be confirmed can be sent to at least part of account nodes in parallel, so that the account nodes of the part 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 document signing account node;
the sending the file to be confirmed to at least one account node related to the file generation instruction includes:
Step S201, according to a preset auditing sequence and the confirmation information of the front account nodes corresponding to each auditing account node respectively, sequentially sending the file to be confirmed to each auditing account node;
Step S202, after receiving the confirmation information of each audit account node in turn, the file to be confirmed is sent to each file signing account node.
In the embodiment of the application, the auditing account node can audit the file to be confirmed, and the file signing account node can sign and confirm the file to be confirmed.
Illustratively, the audit account node may include a superior account node to the account node initiating the file generation instruction, and the file signing account node may include, for example, an external customer account node, a supervisor account node, and the like.
In this embodiment, according to a preset audit sequence and the confirmation information of the pre-account nodes corresponding to each audit account node, the file to be confirmed is sequentially sent to each audit account node, and after the confirmation information of each audit account node is obtained at one time, an audit process of the file to be confirmed can be implemented. Further, the file to be confirmed after the completion of the verification can be sent to each file signing account node. At this time, the file to be confirmed after the completion of the verification may be sent to each file signing account node in parallel, so that each file signing account node may process the file to be confirmed in parallel, thereby improving information processing efficiency.
Step S105, if feedback information of each account node is obtained, and each feedback information respectively meets a 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 generating operation information is generated.
In the embodiment of the application, the respective satisfaction of the respective preset conditions by the feedback information can be determined according to the requirements, attributes and the like corresponding to the account nodes. For example, for a certain feedback information, the feedback information meeting a corresponding preset condition may include: if the feedback information includes the confirmation information and the specific information of the corresponding account node, the feedback information can be confirmed to meet the corresponding preset condition. Of course, the preset conditions can be adjusted according to specific application scenarios. It should be noted that, the confirmation of the document to be confirmed may be determined according to the actual operation of the document to be confirmed. For example, if the document to be confirmed is a contract to be signed, the completing the confirmation of the document to be confirmed may include completing the signing of the contract to be signed.
In the embodiment of the application, the preset conditions corresponding to different account nodes can 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 can be considered to meet corresponding preset conditions;
For the document signing account node, the document signing account node may be an account node of an external client, so that in some specific application scenarios, signature texts of the document to be confirmed can be signed through a USBKEY certificate, and signature ciphertext is obtained, so that the security of feedback information of the account node of the external client is ensured. At this time, the feedback information may include the signature ciphertext information, corresponding USBKEY certificate verification information, signing operation information of the document signing account node, and the like, and if the USBKEY certificate verification information indicates that the USBKEY certificate verification passes, the signing operation information of the document signing account node indicates that the document signing account node confirms that the document to be confirmed is signed, the feedback information of the document signing account node may be considered to satisfy corresponding preset conditions.
The specific storage form of the evidence file may be determined according to the actual application scene, and may include one or more of documents, tables, videos, pictures (such as a screenshot of a related operation page), and the like. The evidence file includes the feedback information and the generating operation information, so that the evidence file may include evidence about related operation processes, and may include evidence such as signature texts, ciphertext, related files and the like of related clients, so that a relatively comprehensive evidence chain may be formed, and the effectiveness of evidence in subsequent evidence is improved.
In some embodiments, after generating the evidence file including the feedback information of each account node and the generating operation information, the method further includes:
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 can be a data storage platform built based on a block chain, and the like. Based on the characteristics of block chain decentralization, non-falsification, whole-course trace and the like, the evidence file can be uploaded to a preset platform for storage, so that subsequent evidence collection can be facilitated, and meanwhile, the preset platform can be used for centralized storage of the evidence file, so that excessive storage space occupied in terminal equipment for executing the embodiment of the application is avoided.
And step S106, authenticating the evidence file and the file to be confirmed after the completion of the confirmation, and obtaining authentication credentials about the evidence file and the file to be confirmed after the completion of the confirmation.
In the embodiment of the application, the mode of authenticating the file to be confirmed and the evidence file can be various, and the method can be specifically determined according to the actual application scene. In some cases, a third party authentication mode with higher public trust may be used to authenticate the document to be confirmed and the evidence document, at this time, the document to be confirmed and the evidence document may be sent to a third party, and an authentication certificate fed back by the third party may be received as an authentication certificate related to the document to be confirmed and the evidence document. Of course, in some cases, the document to be confirmed and the evidence document may also be authenticated by using a user-defined authentication method commonly recognized by a plurality of participants according to the embodiment of the present application.
As shown in fig. 3, in some embodiments, the authenticating the evidence file and the confirmed completed file to be confirmed, obtaining authentication credentials about the evidence file and the confirmed completed file to be confirmed, includes:
step S301, the evidence file and the file to be confirmed after the completion of the confirmation are sent to an authentication platform;
Step S302, receiving a digital certificate obtained after the authentication platform authenticates the evidence file and the file to be confirmed after the confirmation is completed, and taking the digital certificate as the authentication credential.
In the embodiment of the present application, the authentication platform may be a third party authentication platform except for the related party involved in steps S101 to S105. For example, the authentication platform may be a China financial authentication center (CHINA FINANCIAL Certification Authority, CFCA), or the like.
The specific acquisition 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 after the authentication platform processes the evidence file and the file to be confirmed after confirmation 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 acquirer and an evidence authenticator are effectively separated, and the authenticity and the validity of related evidence information are ensured.
In some embodiments, before extracting the target file template and the attribute information of the preset parameters in the target file template according to the file template number characterized in the file generation instruction, the method further includes:
Generating a file template set, wherein the file template set comprises at least one file template and file template numbers corresponding to the file templates respectively, each file template number identifies each file template respectively, 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 the actual application scene, wherein the preset parameters and the attribute information thereof in each file template can be respectively set in a personalized way, thereby realizing flexible configuration of the file templates, having better applicability, improving the development efficiency, needing no repeated development and having lower maintenance cost.
In some embodiments, after the file generation instruction is acquired, extracting the target file template and attribute information of preset parameters in the target file template according to the file template number characterized in the file generation instruction, including:
After acquiring a file generation instruction, acquiring a file template number related to the file generation instruction from a display page related to the file generation instruction;
and acquiring a target file template from the file template set according to the file template number related to the file generation instruction, and acquiring attribute information of preset parameters in the target file template.
In the embodiment of the present application, the display page may be an application page, a web page, or the like, and in some embodiments, the user may trigger the file generation instruction by performing a specific operation (such as a selection operation, an operation of inputting a text, or the like) on the display page, where the display page may be a display page associated with the file generation instruction, and the terminal device may obtain, through information such as a script of the corresponding display page, a file template number associated with the file generation instruction, so that a corresponding file template is searched through the file template number, so as to obtain a target file template.
In some embodiments, each of the above-described file authentication methods may be applied to a blockchain (Blockchain), where the blockchain in this embodiment is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. The blockchain is essentially a decentralised database, and is a series of data blocks which are generated by association by using a cryptography method, and each data block contains information of a batch of network transactions and is used for verifying the validity (anti-counterfeiting) of the information and generating a next block.
