Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of information security, in particular to a verification method and related device. BACKGROUND

[0002] In the current era of network data, the demand for data import using file templates is increasing. Moreover, the requirement for data quality accuracy is also increasing, so in many cases, the file template needs to be verified before data import to ensure that the file template has not been tampered with, and thus to determine the accuracy and security of the data generated according to the file template.

[0003] Taking an excel table file as an example, after generating an excel template, the excel template includes data format, drop-down selection, linkage, and other template rules. The user fills in the data according to the template rules, and the obtained data is standard data that meets the template rules. However, if the user modifies the template rules, the accuracy of the standard data cannot be guaranteed. Therefore, the excel template needs to be verified in the backend. Most of the existing excel template verification technology stacks are based on bean, xml, and configuration for customized development. However, this process requires development and configuration for each excel template, and if the template is modified, the configuration needs to be modified, which will greatly limit the efficiency and portability of excel template verification.

[0079] In order to make the personnel in the technical field better understand the present application scheme, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0080] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0081] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0082] The embodiments of the application are described in detail below.

[0083] Please refer to Figure 1 , Figure 1 is a flowchart of a verification method provided by an embodiment of the application, as shown in Figure 1 , the method comprises the following steps:

[0084] Step 101, the server receives a file template or an edited file sent by the user end.

[0085] The server receives the content sent by the user end, which can be a file template or an edited file. Taking an excel file as an example, the file template refers to a file that has set verification rules for regulating file content, but has not been edited specifically. Please refer to Figure 2A , Figure 2A is a file template provided by an embodiment of the application, as shown in Figure 2A , the file template includes the title of each column and the verification rule corresponding to the file to be edited under each title. For the "gender" column, the content can only be selected from the "male" and "female" tabs, and for the "age" column, only numerical data can be filled in. Figure 2A The verification rule is a schematic display mode, which can be displayed explicitly or hidden and not directly displayed on the file template page.

[0086] The edited file refers to a file that has been edited after the file template is generated. Please refer to Figure 2B , Figure 2B is a schematic diagram of an edited file provided by an embodiment of the application, as shown in Figure 2B , the edited file has been edited in the file template, as shown in Figure 2AThe document template shown has already been edited with details such as name, gender, age, and job title, resulting in an edited document. The identification process between the edited document and the document template can be based on file identifiers. For example, both document templates and edited documents have their own file identifiers, with a specific identifier bit used to distinguish between them. The identifier for document templates is "0," and for edited documents, it's "1." Alternatively, it can detect whether a specific area contains text content. Editing of an edited document always occurs within a specific area, for example, for... Figure 2A To generate an editable file from a file template, text editing is only allowed in the blank areas. Therefore, by detecting whether the editing area contains text data, it can be determined whether the file sent by the client is a template file or an editable file. Alternatively, it is not necessary to identify or detect the file type on the server side; the file type option when uploading the file can be used to determine whether the uploaded file is a template file or an editable file.

[0087] Please see Figure 3 , Figure 3 This is a schematic diagram illustrating a client selecting the file type for uploading, as provided in an embodiment of this application. Figure 3 As shown, the client connects to the server and displays a file type options page provided by the server. The user selects a file type option, such as "template file". The server then receives the file sent by the client and the user's file type option, and determines the received file type as the file type provided by the user.

[0088] Step 102: If a file template is received, determine the template type of the file template. The template type includes a first type of template and a second type of template.

[0089] 103. If the file template is a first type of template, then obtain an existing key from the locally stored key store to encrypt the file template;

[0090] 104. If the file template is a second type of template, then generate a new key to encrypt the file template;

[0091] 105. The server sends the encrypted file template to the user terminal for file editing to generate an edited file.

[0092] The server receives the file template sent by the user end, and needs to encrypt the template so that the file template cannot be changed, because once the template is changed, the subsequent decryption process of the server on the file template cannot be completed. The encryption of the file template by the server can be symmetric encryption, that is, the server configures a key for the file template, and stores the key itself, when the server receives the edited file corresponding to the file template, the key stored by the server is matched with the key of the file template. Or the encryption of the file template by the server can be asymmetric encryption, that is, the server encrypts the file template by using a private key, and stores the public key corresponding to the private key, when the server receives the edited file corresponding to the file template, the public key is used to decrypt the edited file.

[0093] There can be different template types for the file template. The template type is used to distinguish the different security requirements of the template. For the first type of template, the required security level is ordinary, and a special key does not need to be generated, the server only needs to select one from the existing stored keys to encrypt it. For the user's batch upload, even the same key can be used for encryption, which can greatly improve the encryption efficiency of the file template. For the second type of template, the required security level is high, and the server needs to generate a special key for this type of template, which can be generated according to the parameters and characteristics of the template, or according to the template upload time, template business number and other information. The first type of template can be generated by a normally authorized client, and the second type of template can be generated by a high-level authorized client. Or the server interface can provide options, and the template type can be determined according to the received client options.

[0094] Optionally, the server can also obtain the unique identifier of the file template, and then store the unique identifier corresponding to the encryption key and the decryption key of the file template, so that when the edited file generated by the file template is decrypted, the decryption can be matched according to the unique identifier. The keys stored in the server can also be cleared regularly to reduce the storage pressure of the server memory.

[0095] The server sends the encrypted file template to the user end for editing, and the user cannot change the encrypted content in the file template, but can only edit other content. This can effectively prevent the target from being tampered.

[0096] 106、If the edited file is received, the server performs a first check on the edited file, and the first check is used to decrypt the file template corresponding to the edited file.

[0097] The server receives the edited file, and needs to check the file template corresponding to the edited file, to verify whether the file template is a file template encrypted by the server, so as to determine that the file template has not been tampered with in the process of being sent to the client for content editing. The file template is verified whether it is a file template encrypted by the server, that is, the file template is decrypted by using the key stored in the server, and if the decryption is successful, it is indicated that the file template is a file template encrypted by the server, otherwise it is an unencrypted file template.

[0098] Optionally, the first check on the edited file comprises: obtaining an encryption time of the file template corresponding to the edited file; and checking the encryption time to determine whether the encryption time meets a preset time range.

[0099] In some cases, the encryption of the file template is time-limited, for example, the processor only processes the edited file of the file template which is encrypted in batches during this task. Therefore, in the first check on the edited file, in addition to checking the key of the file template corresponding to the edited file, the encryption time of the file template is also checked to determine whether the encryption time meets a preset time range. The encryption time can be added in the form of a time stamp in the template file or the identifier corresponding to the template file, or can be directly added in the form of a date in the target file.

[0100] Step 107, the server determines that the edited file passing the first check is a qualified file.

[0101] The edited file passing the first check indicates that the file template corresponding to the edited file includes key information that can be decrypted by the server, and the file template has not been tampered with, so the security of the file template can be ensured, and therefore the edited file can be determined to be a qualified file.

[0102] In some possible cases, if the encryption information of the server is leaked, there may also be a case of forging the encryption information of the file template. Alternatively, in the case that the template file does not pass the first check of the server, the qualification of the edited file can also be determined by other check methods. Therefore, the second check can also be used to supplement the check method in the embodiment of the application.

[0103] Optionally, after receiving the file template, the method further comprises: obtaining a check rule in the file template; obtaining a unique identifier of the file template; and storing the check rule and the unique identifier correspondingly to generate a check rule table.

[0104] A file template's unique identifier can be used to uniquely identify the file template. Therefore, storing the file template's verification rules and the unique identifier in a corresponding table allows the server to accurately retrieve the verification rules corresponding to the file template using its unique identifier. The unique identifier can be generated based on the user's physical parameters, network parameters, or task parameters, or it can be generated based on the server's task parameters. The generation location can be either the client or the server.

[0105] Optionally, after the server performs the first verification on the edited file, it further includes: obtaining the unique identifier corresponding to the edited file; traversing the verification rule table to determine whether a unique identifier exists in the verification rule table; if a unique identifier exists in the verification rule table, then performing a second verification on the edited file, the second verification being: obtaining the first verification rule corresponding to the edited file and matching the first verification rule with the verification rule corresponding to the unique identifier; if the match is successful, then determining that the edited file has passed the second verification.

[0106] Optionally, if the edited file passes the first verification, after performing the second verification on the edited file, the method further includes: determining that the edited file that passes the first and second verifications is a qualified file.

[0107] Please see Figure 4 , Figure 4 This is a schematic diagram of a traversal verification rule table provided in an embodiment of this application, as shown below. Figure 4 As shown, the identifier 1 of the edited file is obtained, and then the verification rule table is traversed to determine whether identifier 1 is stored in the verification rule table. If it is, the edited file is subjected to a second verification. The specific process is as follows: retrieve rule 1 corresponding to identifier 1 from the verification rule table, and then match rule 1 with the verification rule corresponding to the edited file. During the matching, if the order, constraints, or tabs of the verification rules are exactly the same, the match is successful and the edited file passes the second verification; otherwise, the match fails and the edited file fails the second verification.

[0108] Meanwhile, edited files that pass both the first and second verifications are identified as qualified files. This further ensures the security of edited files. Even if the server's encryption key is leaked, it can be guaranteed that the file template corresponding to the edited file has not been tampered with, thus improving the effectiveness of file verification.

[0109] Optionally, if the edited file fails the first verification, the second verification of the edited file further includes: obtaining the number of times the edited file passes the second verification; if the number of times the edited file passes the second verification is less than the preset number, the edited file is determined to be a qualified file; and the number of times the edited file passes the second verification is incremented by one.

[0110] After the first check on the edited file, if the edited file fails to pass the first check, it means that the file template of the edited file has not been encrypted by the server in advance. In some cases, the file template of the edited file can be generated by copying the file template of another server-encrypted file, and the file template itself is not tampered with, but the encryption process is omitted. Such edited files can also be confirmed by the server as qualified files, and the step of re-uploading the file template of the edited file by the user terminal for encryption is omitted to improve the efficiency of the check. However, if all edited files that pass the second check but fail the first check are considered as qualified files, the first check process loses its meaning, and a large number of edited files with file templates not encrypted by the server uploaded to the server can also cause unauthorized user terminals to upload some unnecessary edited files, increasing the data processing capacity of the server.

[0111] Therefore, the server can only confirm a limited number of edited files corresponding to the same file template as the signed file template as qualified files. The specific process is as follows: store all server-encrypted file templates in the server and set a qualified number of times for each file template, and the initial value of the qualified number of times is 0. Each time the server receives an edited file with an unencrypted file template, but the edited file passes the second check, the qualified number of times of the file template corresponding to the edited file stored in the server is increased by 1. When the qualified number of times of the file template stored in the server is not less than a preset number of times, if the server receives an edited file corresponding to the file template again, as long as it fails to pass the first check, the edited file is determined to be an unqualified file.

[0112] In some cases, the edited file fails to pass the first check, indicating that the file template of the edited file has not been encrypted by the server in advance. The second check is continued on the edited file, and the edited file passes the second check, indicating that the file template of the edited file has been stored in the server. At this time, it can be because the number of server-signed file templates is not enough, causing the user terminal to generate an unencrypted file template by copying an encrypted file template, and then generate an edited file by editing the file in the unencrypted file template. Because the server's encryption information cannot be copied when copying the file template, the edited file cannot pass the first check, but the edited file is undoubtedly a qualified file. In this case, the edited file can be provided with the opportunity to provide a supplementary signature, and the specific process is as follows:

[0113] The server obtains the unique identifier and the check rule corresponding to the edited file that passes the second check;

[0114] The server generates a file template corresponding to the edited file according to the unique identifier and the verification rule; or, the server can also obtain the verification rule corresponding to the unique identifier stored in the verification rule table of the server according to the unique identifier, and then generate the file template;

[0115] The server outputs a file template share request to the user end, and receives the template share input by the user;

[0116] The server encrypts the file template corresponding to the template share, and sends the encrypted file template to the user end;

[0117] The user end edits the file template, generates an edited file, and sends the edited file to the server;

[0118] The server performs a first verification on the edited file, and determines that the edited file passing the first verification is a qualified file.

[0119] This process can avoid the limitation caused by the verification order of the first verification and the second verification, effectively combine the first verification and the second verification, and improve the verification accuracy.

[0120] It can be seen that in the embodiments of the present application, the server receives the file template or the edited file sent by the user end; if the file template is received, the server encrypts the file template, and sends the encrypted file template to the user end for file editing to generate an edited file; if the edited file is received, the server performs a first verification on the edited file, and the first verification is used to decrypt the file template corresponding to the edited file; the server determines that the edited file passing the first verification is a qualified file. In this process, the file template is encrypted, so that when the edited file is received, the file template is decrypted to complete the verification of the file template, which improves the security of the file template and improves the verification efficiency of the file template.

[0121] Please refer to Figure 5 , Figure 5 is a verification method flowchart provided by the embodiments of the present application, as shown in Figure 5 , the method comprises the following steps:

[0122] Step 501, the server receives the file template or the edited file sent by the user end;

[0123] Step 502, if the file template is received, the server obtains the verification rule in the file template, and obtains the unique identifier of the file template;

[0124] Step 503, the server stores the verification rule and the unique identifier correspondingly, and generates a verification rule table;

[0125] Step 504, the server encrypts the file template and sends the encrypted file template to the user terminal for file editing to generate an edited file;

[0126] Step 505, the server performs a first check on the edited file, and the first check is used to decrypt the file template corresponding to the edited file;

[0127] Step 506, the server obtains the unique identifier corresponding to the edited file, traverses the check rule table, and determines whether the unique identifier exists in the check rule table;

[0128] Step 507, if the unique identifier exists in the check rule table, the server performs a second check on the edited file, and the second check is: obtaining the first check rule corresponding to the edited file, and matching the first check rule with the check rule corresponding to the unique identifier; if the matching is successful, it is determined that the edited file passes the second check;

[0129] Step 508, the server determines that the edited file passing the first check and the second check is a qualified file.

[0130] The above steps 501-508 are that the server simultaneously performs a first check and a second check on the received edited file, and determines that the edited file is a qualified file in the case that the edited file passes the first check and the second check. For specific description, refer to the corresponding description of the check method described in steps 101-107, which will not be repeated here.

[0131] It can be seen that in the embodiments of the present application, whether the edited file is a qualified file is determined through the first check based on the server signature and the second check based on the file template check rule, which improves the accuracy and reliability of the check.

[0132] Please refer to Figure 6 , Figure 6 is another check method flowchart provided by the embodiments of the present application, as shown in Figure 6 , the method comprises the following steps:

[0133] Step 601, the server receives the file template or the edited file sent by the user terminal;

[0134] Step 602, if the file template is received, the server obtains the check rule in the file template, and simultaneously obtains the unique identifier of the file template;

[0135] Step 603, the server stores the check rule and the unique identifier correspondingly to generate a check rule table;

[0136] Step 604, the server encrypts the file template, and sends the encrypted file template to the user terminal for file editing to generate an edited file;

[0137] Step 605, the server performs a first check on the edited file, and the first check is used to decrypt the file template corresponding to the edited file;

[0138] Step 606, a unique identifier corresponding to the edited file is obtained, and the check rule table is traversed to determine whether the unique identifier exists in the check rule table;

[0139] Step 607, if the unique identifier exists in the check rule table, a second check is performed on the edited file, and the second check is that a first check rule corresponding to the edited file is obtained, and the first check rule is matched with a check rule corresponding to the unique identifier; if the matching is successful, it is determined that the edited file passes the second check;

[0140] Step 608, if the edited file does not pass the first check, the server obtains a file template mark qualified number corresponding to the edited file that passes the second check;

[0141] Step 609, if the mark qualified number is less than a preset number, the server determines that the edited file is a qualified file, and increases the file template mark qualified number by one.

[0142] The above steps 601-609 are that the server simultaneously performs the first check and the second check on the received edited file, and in the case that the edited file does not pass the first check but passes the second check, allows to determine the edited file as a qualified file for a limited number of times.
