Description
Technical Field
The invention relates to a method and a device for processing an electronic form document.
Background
An electronic form file is a form-based electronic file, such as a PDF form or other electronic file with form definition and description, and is currently widely applied to electronic file processing in various application fields, such as electronic files used for online declaration, approval, internal office, government information collection, delivery, and the like in the field of electronic government.
The recording of current electronic form files still has some drawbacks. For example, documents such as PDF and HTML include definitions of forms and form fields, but the documents store only the results of generating the electronic form documents, and the document does not describe therein the conversion process of the form field values. Although the documents such as PDF support description and definition of the form and form field and can perform digital signature for many times, the filling change process of the form field, such as the filling time of each filling record, the filling person information, the original value of the form field, the value of the form field after filling, the information of the filling program used, the source information of the numerical value of the form field to be filled, and other filling parameter information, is not recorded. Also, the form field does not have file attribute information, such as the form field last fill time, last fill staff information, last fill procedure information, last fill data source information, and other fill parameter information.
In most applications, the form field value and the change process information of the value of the HTML form are stored in the system database as application program logs, so that the change process information of the form field value is stored outside the form file, which is not beneficial to query and exchange of the form field value change information.
Since the electronic form file does not internally contain the conversion process information describing the form field data and cannot provide information on the generation and change history of the form field data, the electronic form file itself does not have the credentialing feature of recording the generation and change process of the form field data.

Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
An electronic form file is a file with an electronic form description. The electronic form file is generated after being designed by a form design program, and the electronic form file can be filled in once or more times to generate an electronic form file record. The electronic form is a computer program version of a paper form; in addition to eliminating the cost of printing, storing and distributing pre-printed forms, users can fill out electronic forms more quickly with electronic form files because the programs associated with the forms can automatically format, and calculate, find and verify information. The electronic form generally comprises appearance description of the form and the form field, form service logic definition, form field definition and data for storing the form field; the form fields typically include a text field, a radio field, a combo box field, a date field, a time field, a file field, a sign-on field, etc., and the definition of the form fields includes the location, type, format, field name, etc. of the form fields. An electronic form file used in an embodiment of the present invention includes a number of form fields that can interactively collect data information as form field data (also referred to as form field values, values of form fields). Two types of interactive form files, such as PDF form files: such as PDF based AcroForm, independent form description XMLForms Architecture (XFA). The invention is not limited to the examples described above. The invention is applicable to any other electronic form file containing form fields.
The electronic form document can be filled in by one or more operators on the client side, and the electronic form document is signed by the operators or by a rechecker after the completion of the filling in. The operator can fill in a part of data, and the operator can sign on a signature field or a blank part of an electronic form file; or other people can help to fill in a part of data to operate the signature of the responsible person; signature and recheck approval can also be made by the rechecker to the electronic form document filled in by the operator. The signature mode is realized by adopting a digital certificate of a signatory to carry out full-text digital signature on the whole electronic form file, and the digital signature has the significance of approving the final result filled in the electronic form file and the log recorded.
FIG. 1 shows a flow diagram of a method for processing an electronic form file, according to an embodiment of the invention. The method 100 comprises: during the processing of an electronic form file, acquiring entry attribute data relating to the generation and change of form field data in the electronic form file (step 101); and recording the entered attribute data in an electronic form file (step 102).
In an embodiment of the invention, the entered attribute data comprises a collection of entered attribute data generated and changed in a plurality of processes of the electronic form file (such as a data entry process, a form filling process, a data modification process, etc.), forming an entry log. For example, when an electronic form is recorded, an entry log with entry attribute data is automatically recorded; when a user manually fills in an electronic form file on a computer or adopts automatic data entry equipment to enter data into form fields of the electronic form file, relevant attribute data of each form field are recorded into an entry log after effective filling is completed each time. After the forms are filled in for many times, an electronic file record with a form field and an input full log is formed in the electronic form file, wherein a detailed filling record evidence chain is arranged for each form field in the electronic form file, and the whole electronic form file has a complete input log evidence chain. According to the electronic form file processing method, all the entry logs of all the form fields of the electronic form file can be completely saved, wherein the saved entry attribute data has the characteristics of evidence chain and traceability.
In an embodiment of the invention, the logging property data comprises at least one of: time entered, personnel information entered, review personnel information, original values of form fields, new values of form fields, program information for processing electronic form files, client information for processing the electronic form files, entered data source information (e.g., information for direct picking equipment as a source of data, user manual keyboard entry, etc.), information for an entered program for automatically entering form field data, physical environment information for entering attribute data, and other entered parameter information.
In the process of creating the electronic form file, the information of operators, program system information, project information, file parameter information and the like for creating the electronic form file can be recorded in an input log of the electronic form file; during the filling process of the electronic form file, the data effectively filled in each form field at each time is recorded in an entry log, wherein entry attribute data comprise filling time, filling personnel information, original values of the form fields, new values of the filled form fields, adopted filling program information, client information, data source information (such as direct acquisition equipment information and manual entry keyboard entry) and other filling parameter information, the entry attribute data are utilized to generate the form field entry log, and the entry log is written into the electronic form file.
The filling time of the form field includes, but is not limited to, year, month, day, hour, minute, second, time zone during each filling of the form field. Under the condition that a plurality of persons fill in an electronic form in different places through a network server, time calibration needs to be carried out in advance to ensure the accuracy of a time line, for example, a plurality of users are calibrated with Beijing time, or calibrated with a system server, or calibrated with an enterprise time service server. The client may also always calibrate time through a Network Time Protocol (NTP) service with a standard time service, or a system time service. The filler information generally refers to information that can uniquely mark the filler, including but not limited to the user's account number, the user's name, the user's role or job (e.g., researcher, nurse, etc.). The original value of the form field refers to the value of the form field before the present filling, and the new value of the form field after the present filling refers to the value of the form field after the present filling. The filling program information used refers to the filling program information used in the filling, and includes, but is not limited to, the name and version of the filling program. The filling-in program refers to a program for filling in an electronic form (for example, a software program Adobe acrobat7.0professional for generating and processing a pdf file); however, the filling program can interface system environment information, collect client information and the like, and can be used for opening an electronic form file to fill data. When a plurality of users process electronic form files using a network, the input attribute data may be collected online or offline in step 101. When multiple persons collect the electronic form files on line, a certain mechanism, such as a file lock, is used for avoiding file collision, so that the collection and storage sequence of the electronic form files is ensured, and the time sequence of the final log input of the electronic form files is ensured.
The client information refers to a client host identifier, a computer name, etc. used by the user to fill in the form. The data source information refers to the place from which the data filled in this time comes, and mainly includes a recording mode, a recording equipment model and the like. For example, data is collected by a direct acquisition device and a filling program directly connects to the device to provide filling data. In the case where the operator uses the sphygmomanometer to measure the blood pressure, the data source information may include equipment information of the sphygmomanometer, a model number of the sphygmomanometer, a unit of the sphygmomanometer, a normal value range of the sphygmomanometer, and the like; of course, the data can be entered by a filling person through a manual keyboard or copied and pasted. The data source information can reflect that the data entry mode is manually entered or automatically entered into the electronic form file. For example, in the case of acquiring electrocardiogram data, after the electrocardiogram is photographed, the electrocardiogram data is automatically entered into an electronic form opened by a client filling program. Other filling parameter information entered into the attribute data may include filling specifications, such as environmental information (indoor or outdoor, temperature, humidity, etc.).
In an embodiment of the invention, the method 100 further comprises: a digital signature is appended to a signature field in the electronic form file. The operator causes the entire electronic form file after processing (including the entered attribute data written therein) to be protected by the digital signature by superimposing the digital signature in the signature field of the electronic form file.
In an embodiment of the present invention, the entry attribute data may be log data in an extensible markup language (XML) format or a JSON (JavaScript Object Notation) format. If the form field is effectively filled in each time of file storage, a form field input log record is generated and stored in metadata of the electronic form file; and updating the final filling time, the final filling staff information, the final value, the finally adopted filling program information, the final data source information and other filling parameter information of the relevant form field.
In an embodiment of the present invention, when a save operation is performed on an electronic form file or a digital signature is added to a signature field in the electronic form file, entry attribute data is written as an entry log into metadata of the electronic form file. In this embodiment, the entry attribute data may be saved as a file modification log data item in the metadata of the electronic form file, and the value of the data item may be log data in XML or JSON format.
The entry log is written into the electronic form file at a time after completion of effective filling of the form field, including a save operation of the electronic form file after each filling or a digital signature. The invention is not so limited.
Active fill refers to filling that causes the value of the form field to change. The software system has a set of judgment rules for judging whether the filling of the user is effective, for example, when the user inputs characters in a text field of the electronic form file, a cursor flickers in the text field after entering a focus mode, at the moment, the user can input the characters in the text field, and at the moment, the input text field is in the focus mode; other form fields also have focus patterns with different effects, for example, the focus pattern of the date field will pop up a date selection dialog box, etc. As long as the form field is still in focus mode, the user may continue to enter data entry, or modification into the form field, which has not yet been validly filled in. After the user completes the filling of the form field, the user presses an enter key on the keyboard to judge that the user exits the focus mode; if the value of the form field changes at this moment, the filling of the form field is effective filling; if the value of the form field has not changed, it is considered to be invalid fill. Other valid filling judgment rules are that if the illegal check logic of the form field can not be passed, valid filling is not carried out; if the user fills in a certain form field, the value of the other form field is changed due to the form calculation logic, and the other form field is passively filled in and recorded and calculated on the head of the filling user; the effective time of the filling records is the file saving operation, and in addition, the signature operation of the signature domain can also indirectly trigger the file saving operation. If the user fills data in a single form field for multiple times before single storage operation, the last filling is effective during storage, and the original value of the form field is the initial value of the form field before single storage. For example, if the original value in the address field in the electronic form file is "beijing", the user inputs "shanghai", presses the enter key to go back to the focus mode, inputs "guangzhou" again, presses the enter key to go out of the focus mode, and clicks on save, the filled-in record value changes from "beijing" to "guangzhou".
After each form field finishes the valid value filling, the recorded form field log data can be put in a cache before being actually written into the electronic form file; all the form field log data in the cache is written into the electronic form file only when the electronic form file is saved or an electronic signature is added. By caching the logged form field log data, erroneous or inadvertent logging of erroneous data by the logging operation can be filtered out. For example, the value "shanghai" of the form field as described above may be entered unintentionally by the user, and it will be filtered out and not written as log data into the electronic form file.
In an embodiment of the present invention, when a digital signature is added to a signature field in an electronic form file, a digest algorithm and a digest value of an entry log are written into a signature dictionary of the electronic form file. For example, an operator may protect the entire filled-in electronic form file, including the entry log of the form field, by digitally signing the electronic form file with a digital certificate in the signature field. After the operator signs, the log recorded in the form field is written into the metadata of the electronic form file, the log recorded is associated, and the abstract algorithm of the log recorded are written into the signature dictionary. The present invention is not limited to writing the entry log in the metadata of the electronic form file. The log of all form field value changes clearly records all relevant parameters of the change, filling personnel, original values before filling, new values after filling, filling time, modification reasons, client information modification, system environment modification information modification, program relevant modification information and the like. The abstract algorithm and the abstract value of the log are written into a signature dictionary of the electronic form file and used as part of signature expansion information, and responsibility attribution can be carried out on the log recorded in the form field, so that responsibility of data filling or recording personnel can be traced in a subsequent stage. In addition, digital signatures can be added to achieve tamper protection of electronic form documents. When the electronic form file is published outwards, various modifications are inevitable; if the electronic form file is tampered, the operator can fail to check the digital signature added on the electronic file, and then the user can be reminded that the data is tampered, so that the tampering protection effect is achieved.
In an embodiment of the invention, the method 100 further comprises: before the form field data is entered, the entered attribute data is collected with respect to the form file handler, the client, the hardware and software information related to the entry operation, and the environmental information.
Entry of form field data includes generation and modification of form data. In one example, prior to entry of form field data, when an electronic form file is opened, client host information (e.g., client host identity, machine name, etc.), system information for an electronic form file handler, user identity information, server time information, information for the filling program, ambient temperature and humidity, etc. is collected by executing a particular form filling program. But the collection of such information is not limited to just prior to entry of form field data. When any form field filling or form state modification occurs in the electronic form in the processing process of the electronic form file, the log not only simply records the numerical value change of the form field, but also records the system environment parameter change corresponding to the numerical value of the form field. The specific form filling program is a form filling and information acquisition program which can be used for acquiring all system environment parameters (including client information, data source information, system environment information and the like); the specific form filling program collects system parameters and environment parameters of form field value change as much as possible for subsequent audit check of the electronic form document. After the particular form filling program collects and loads the system information and the environment information, the electronic form file is opened for form filling, with the generation of log data associated with the filling or modification of the form fields. The specific form filling program can exist in various forms, such as a mobile phone version APP, a desktop version application, a browser plug-in and the like. The particular form filling program may not be embedded in the electronic form processing program.
The system environment information may include a system website, a system name, a project name, and the like. The user identity information may include an account ID, an account name, an account role, and the like. The client information may include client host information, client IP, etc. The acquisition program version information may include the name of the acquisition program, the version of the acquisition program, and the like.
In another example, the client times are calibrated as necessary according to a specified clock by having all clients register in advance to obtain client information and synchronizing all clients in time as necessary. When processing an electronic form file, the user identity can be verified by logging in the system by an account so as to obtain the identity and role information of a form writer. The method is characterized in that related hardware equipment used for processing the electronic form file is connected to directly acquire parameter information related to the hardware equipment. In the process of processing the electronic form file, a system service script can be loaded to realize filling of the intelligent form, and the system service script comprises an initialization script, a logic control script, a logic verification script, an automatic calculation script, an operation script related to a form field and the like. The entry log may also record information related to system service scripts used during processing of the electronic form file. In another example, a program can be filled in by using a specific form, and an operator can be switched and input in a user account switching mode, or a multi-person joint signature operation can be realized in an interactive interface in a multi-person countersignature mode; in which a digital signature must be verified, such as a fingerprint verification or entering a signer password, while user information of a switched operator or multiple users of a joint signature may be collected.
The user information and the auditor information belong to a file processing system, the identities of the user and the auditor can be confirmed through the login operation of the user and the auditor in a client acquisition program, and the user identity information and the auditor identity information are obtained.
Fig. 2 shows an example of an electronic form file used in the embodiment. The electronic form file 200 shown in the figure is a subject screening form in a clinical trial, and includes a screening form header 210 and a basic information form 220. The screening header 210 includes form fields for protocol number, study period, subject name abbreviation, and screening number. The basic information table 220 includes form fields such as date collected (date field), name (radio field), gender, date of birth (date field), age, ethnicity (radio field), identification number, phone, emergency contact and phone, registrant signature (signature field), alternative (radio field), auditor (signature field), etc. When the electronic form file 200 is filled in, each form field has a new value, and the entered attribute data includes at least the new value of the form field and its last filling time. The valid digital signature of the writer's signature and the verifier indicates that the signed document is legitimately modified, that the signer's identity is verified, and that the impression is verified. After the electronic form file 200 is modified, the original new value in the form field is changed into the original value, and the current modified value is changed into the new value; the original values, new values and their last filling times of all form fields are saved as entered attribute data.
Where the electronic form file 200 resides on a client and is generated or modified on the client, the entered attribute data will be written into the electronic form file 200 on the client. In the case where the electronic form file 200 resides on a server on a network and can be generated or modified by a plurality of clients on the network, the entered attribute data will be written into the electronic form file 200 on the server, while the entered attribute data may also include at least client information for processing the electronic form file 200, such as information of the client modifying certain form field data (e.g., the signature of an "auditor"). The entered attribute data may be generated at the client during file processing and then transmitted and stored in an electronic form file or database at the server.
FIG. 3 shows a schematic diagram of forming multiple modified versions of an electronic form file during generation and modification of the electronic form file, according to an embodiment of the invention. As shown in fig. 3, the initial version of the electronic form file includes the electronic file body, the electronic file metadata, and the digital signature. The text comprises descriptions of documents, pages, resources, scripts and the like, and the most important description is the description containing the electronic form; an electronic form contains one or more form fields that are distributed across one or more pages of an electronic form file, describing the electronic file along with background text. The electronic file metadata contains author, modification time, and the like. The electronic form file can be selectively added with an authentication signature to indicate subsequent authority of the file, whether form filling is allowed or not, whether signature is allowed or not and the like.
After the electronic form file is modified for a plurality of times (for example, N times), modified versions 1 to N shown in fig. 3 are formed correspondingly, and each modified version contains incremental modification to the body and incremental modification to the metadata. The incremental modification of the text mainly refers to the filling of form field values of the electronic form, and the incremental modification of the metadata refers to all changes (form field filling logs) of the file during each storage; if the file saving action is executed in the file processing, the direct incremental modification does not make a signature; and if signature action is executed in file processing, performing operator identity verification and adding a digital signature, performing signature protection on incremental form filling of a text and an incremental file modification log of metadata, and writing a digest algorithm and a digest value recorded in the log into a signature dictionary.
FIG. 4 shows a schematic diagram of forming multiple modified versions of a modification log of an electronic form file during modification of the electronic form file, according to an embodiment of the invention.
In the process of modifying the electronic form file, when the numerical value of the form field changes, the modified filling-in personnel information, time information, the original value of the form field, the new value of the form field, filling-in program information, client information, system information, data source information and the like are read, an electronic file modification log containing the information is generated, and the electronic file modification log is written into a file modification log cache. When the electronic form file is saved or the digital signature is added in the electronic form file, the file modification log is cached and written into the electronic form file in an incremental modification mode. The incremental modification refers to writing all electronic file incremental modification and signature data in the tail part of the original electronic form file, maintaining the old version file unchanged, and updating the structure index of the file to show the new version file, which is shown in fig. 3 and 4. When a digital signature is added and an electronic form file is stored, a digest algorithm and a digest value of an input log are written into a signature dictionary of the electronic form file.
Each time an electronic form file is saved or digitally signed, the electronic form file modification log is added with a version (such as modified version 1, modified version 2, … and modified version N shown in figure 4), each modified version is provided with a plurality of entry logs (such as form field modification log 1, form field modification log 2, … and form field modification log M shown in figure 4), and each log contains log parameters as many as possible.
Referring to fig. 4, the file modification log exists in two dimensions, the primary directory is modified versions 1 to N, and each modified version may have a digital signature or may not have a digital signature; the secondary directory is a form field data item modification log (i.e., form field modification log 1, form field modification log 2, …, form field modification log M). If the modified version information and the form data item modification information are read during use, a series of modified versions and saving personnel, saving time, whether to sign, client information during saving, form filling program information and the like related to the modified versions are obtained. Meanwhile, when a certain modified version is checked, all numerical value modification logs aiming at the form field under the version can be checked, and the logs comprise filling personnel, filling time, client information, form filling program information and the like. In addition, if the version information is ignored and only the secondary form field modification information of the whole file is checked, the file is a modification log list for performing numerical value transformation from the original version to the final version and all form fields, and the log comprises filling personnel, filling time, client information, form filling program information and the like. If the log protected by the digital signature is modified, the form filling program prompts the file to be modified and the signature verification fails, and prompts the user to carefully continue the form filling operation or not to continue filling the form.
