Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

According to an embodiment of the present application, a document encryption method is provided.

Fig. 1 is a flowchart of a document encryption method according to a first embodiment of the present application. As shown in fig. 1, the method comprises the steps of:

step S101 configures a plurality of secret levels.

A privacy level, abbreviated as "confidentiality level," is a distinction between the degrees of confidentiality of the contents of a document, and a document is provided with a privacy level for identifying the degree of confidentiality of the contents of the document so that a user can save and use the document according to the privacy level of the document.

For example, a confidential document is classified into a core secret and a business secret, three secret levels, namely, a first secret level, a second secret level and a third secret level, are configured in the core secret, and two secret levels, namely, the first secret level and the second secret level, are configured in the business secret. In particular, different privacy levels may be configured to attach different rights ranges, knowledge ranges, and the like. The permission range may include read-only, readable-writable, shareable, and the like. The user, who knows the scope can be used to specify what role can get the document. Further, the document is saved and used according to the attribute added by the secret level.

Step S102, configuring a plurality of secret bases and associating each secret base with a corresponding secret level;

the above-mentioned secret-determining basis may be a legal regulation prescribed in a secret-related country or a secret-related rule set inside each enterprise. For example, the secret rating basis established by the enterprise a is B, and the secret level corresponding to the secret rating basis B is the first secret level.

One secret-determining basis corresponds to one secret level, and each secret-determining basis is associated with the corresponding secret level, so that the corresponding secret level can be quickly found by the subsequent secret-determining basis.

Step S103, configuring a plurality of secret types, and associating each secret type with a corresponding secret level to establish an association relationship among a secret determination basis, the secret level and the secret type.

In one embodiment, the security types may include: a privacy deadline, a decryption condition, and a decryption date, the privacy deadline, the decryption condition, and the decryption date being associated with a corresponding privacy level.

For example, the privacy deadline corresponding to the first privacy level is a first privacy deadline, the first privacy level is associated with the first privacy deadline, and the privacy deadline corresponding to the first privacy level may be determined to be the first privacy deadline as long as it is subsequently determined that the privacy level is the first privacy level. For another example, the decryption condition corresponding to the second secret level is a second decryption condition, the decryption date corresponding to the second secret level is a second decryption date, the second secret level is associated with the second decryption condition and the second decryption date, and as long as it is determined that the secret level is the second secret level, the second decryption condition corresponding to the second secret level, and the second decryption date corresponding to the second secret level can be determined quickly.

For another example, one secret level may be associated with a plurality of secret types, for example, the secret term corresponding to the first secret level is a first secret term and a second secret date, the first secret level is associated with the first secret term and the second secret date, and as long as it is subsequently determined that the secret level is the first secret level, one secret type may be selected from the first secret term and the second secret date as the secret type corresponding to the document encrypted by the first secret level.

The method is used for establishing the association relationship among the secret determination basis, the secret level and the secret type. For example, the first level of security corresponds to a security period of 30 days, and the decryption conditions are: MMM, decryption date: in XX month XX day of XX year, only the secret setting basis is determined, and correspondingly, the secret setting basis can be obtained quickly according to the corresponding secret grade and secret type (secret duration, decryption condition and decryption date) according to the incidence relation of the three, so that the efficiency and accuracy of determining the secret grade and the secret type according to the secret setting basis can be improved.

It should be noted that how to establish the association relationship among the secret-determining basis, the secret level, and the secret type is not limited in this embodiment. For example, the secret-determining basis, the secret level, and the secret type may be stored in the same entry of a database or a configuration file to establish the association. Under the condition that the incidence relation among the secret fixing basis, the secret level and the secret type needs to be determined, data can be read from the database or the configuration file, and under the condition that the secret fixing basis, the secret level and the secret type are stored in the same item of the database or the configuration file, the incidence relation among the secret fixing basis, the secret level and the secret type can be determined.

And step S104, carrying out encryption processing on the document according to the association relation of the encryption basis, the secret level and the encryption type.

After the association relationship among the encryption basis, the secret level and the secret type is established, when the document is subjected to encryption processing, the corresponding secret level and the corresponding secret type (the encryption period, the decryption condition and the decryption date) of the encryption basis can be obtained only based on the encryption basis selected aiming at the document, so that the document is subjected to encryption processing according to the encryption basis selected aiming at the document, the secret level and the corresponding secret type, and the user can conveniently carry out multi-level screening based on the multi-level association relationship by associating the secret level with the secret type according to the encryption basis, so that the document is subjected to encryption processing after the correct encryption basis, secret level and secret type are obtained, the problem that the document encryption fails due to the fact that the encryption basis, the secret level and the secret type do not correspond is solved, and the problem that the document encryption fails due to the fact that the user needs to try various encryption bases, secret levels and secret types is also avoided, The combination of the secret grade and the secret type can only mark the document correctly, the times of marking the document secret are reduced, the efficiency and the accuracy of marking the document secret are improved, the workload of subsequent checking the document secret is reduced, the working efficiency of a secret check verifier is improved, and software and hardware resources used by the document secret are saved.

Optionally, in the document encryption method provided in this application, after configuring the plurality of secret levels, the method further includes: configuring a secret level identifier of each secret level; associating each secret reference with a corresponding secret level comprises: and associating the secret rating basis with the secret level and the secret level identification.

For example, the secret level identifier of the first secret level is four, the secret level identifier of the second secret level is Δ, and the secret level identifier of the third secret level is four, and by configuring the secret level identifier of each secret level and associating each secret reference with the secret level identifier corresponding to the secret level and the secret level, for example, if the first secret reference corresponds to the first secret level and the secret level identifier of the first secret level is four, the first secret reference, the first secret level and the secret level identifier are associated. When the document is subsequently encrypted, besides the characters of the secret level, the identification of the secret level can be displayed, so that the encryption result of the document can be displayed more intuitively and accurately for the user.

Optionally, in the document encryption method provided in this embodiment of the present application, before configuring a plurality of security types and associating each security type with a corresponding secret level to establish an association relationship among a basis for secret determination, the secret level, and the security type, the method further includes: and configuring a corresponding display control for each security type.

For example, the security types described above may include: the security period, the decryption condition, and the decryption date, as shown in fig. 2. Before the association relationship among the secret-determining basis, the secret level and the secret type is established, a corresponding display control can be configured for each secret type, as shown in fig. 3. For example, the display control corresponding to the security deadline is configured as a drop-down box, a plurality of security deadlines, such as 7 days, 15 days, 30 days, and the like, may be set in the drop-down box, and may also be set. The display control corresponding to the decryption condition can be configured as an input box, and a user can input a custom decryption condition. The display control corresponding to the decryption date can be configured as a date box, and when the user sets the decryption date, any date after the current date can be selected in the date box.

The display control corresponding to each confidential type is configured through the scheme, so that the user can configure the confidential types more conveniently subsequently, and the working efficiency and the experience of the user are further improved.

Optionally, in the document encryption method provided in this embodiment of the present application, performing encryption processing on the document according to an association relationship among an encryption basis, a secret level, and a secret type includes: receiving a selected secret-determining basis for the document; determining a secret level corresponding to the secret determining basis according to the association relation; determining a secret type according to the secret level corresponding to the secret determining; and carrying out encryption processing on the document based on the secret level and the secret type.

For example, when a document needs to be encrypted, if a user selects an encryption basis, the encryption basis is correspondingly obtained according to the corresponding secret level and the corresponding secret type (the encryption term, the decryption condition and the decryption date) according to the association relationship among the encryption basis, the secret level and the secret type, and specifically, the secret level can be selected after the encryption basis is selected through the first-level association relationship between the encryption basis and the secret level; further, through the secondary association relationship between the secret level and the secret type, at least one secret type associated with the secret level can be determined, and the user can select one secret type conveniently. And performing multi-level screening by the user based on the multi-layer incidence relation to obtain correct secret-determining basis, secret level and secret type. And then, the document is subjected to encryption processing according to the corresponding secret level and the corresponding secret type of the encryption basis, so that the problems that in the prior art, a document drafter is required to be very familiar with the encryption rule, otherwise, the situation that the encryption basis is not matched with the secret level occurs or the protection range of the encryption term exceeding the secret level requirement exists, but a plurality of document drafters in an enterprise are not very familiar and thorough to understand the encryption rule are solved, the technical effect of linkage control of the encryption basis, the secret level and the secret type is achieved, and the efficiency and the accuracy of encryption processing on the document can be improved.

In order to further ensure the accuracy of the document encryption processing, optionally, in the document encryption method provided in this embodiment of the present application, after receiving the selected encryption basis for the document, the method further includes: judging whether the secret basis is matched with the document; if the matching is successful, executing a step of determining a secret level and a secret type corresponding to the secret determining basis according to the association relation; and if the matching fails, triggering reminding information to remind that the selected password-fixing basis is wrong.

When the secret-determining basis is matched with the document, a keyword can be extracted from the document, and the keyword is compared with the secret-determining basis.

For example, the document a needs to be subjected to encryption processing, after the user selects the encryption basis a for the document a, in order to ensure accuracy, the background extracts keywords in the document a, and matches the keywords with the encryption basis a, for example, a preset keyword list is determined according to the encryption basis a; when the number of the keywords in the document A is the same as that of the keywords in the keyword list exceeds a preset threshold value, the document A and the secret-setting basis A are determined to be matched successfully, the selected secret-setting basis is indicated to be correct, the step of determining the secret level and the secret type corresponding to the secret-setting basis according to the incidence relation can be continuously executed, and if the matching fails, the user is indicated to select the secret-setting basis A which is wrong according to the document A, and reminding information is triggered to remind the user so that the user can select the secret-setting basis again. By the scheme, the accuracy of selecting the secret-setting basis for the document is ensured, and the accuracy of performing secret marking processing on the document subsequently is ensured.

It should be noted that, in the technical scheme for matching the document with the fixed-density basis in the present application, in addition to the above-mentioned scheme for matching the keyword in the document with the fixed-density basis, similarity between the keyword in the document and the keyword determined by the fixed-density basis may be calculated, and if the similarity exceeds the preset similarity, it is determined that the document is successfully matched with the fixed-density basis, so that a specific technical scheme for matching the document with the fixed-density basis in the present application is not limited.

In order to further ensure the accuracy of the selected document density determining basis, optionally, in the document density marking method provided in this embodiment of the present application, the receiving the selected document density determining basis includes: extracting key words in the document; displaying a secret-determining basis matched with the keywords; receiving user operation acting on a secret-setting basis; and responding to the user operation, and determining the privacy-determining basis acted by the user operation as the selected privacy-determining basis for the document.

The scheme for extracting the keywords in the document in the above scheme may be based on a natural language processing algorithm, for example, performing word segmentation processing on the document to obtain a plurality of words, counting the frequency of each word appearing in the document, and using the word with the frequency higher than a preset frequency as the keyword of the document. For example, the keywords in the document are compared with the keywords in each preset keyword list determined by the density determining basis one by one, and when the number of the keywords in the document is the same as the number of the keywords in at least one target keyword list exceeds a preset threshold value, the density determining basis corresponding to the target keyword list is determined as the density determining basis for keyword matching.

For example, the keyword may be matched with one or more privacy bases, the matched privacy bases are displayed for the user to select, and the selected privacy bases are used as the privacy bases of the document.

Optionally, as shown in fig. 4, in the management background, firstly defining the secret level and the secret level content (i.e., the secret level identifier) in the background, then defining the secret reference in the background, associating the secret level with the input secret reference content (corresponding to the associated secret level 1 in fig. 4), and finally defining the secret term content (which may also be understood as the secret type) in the background, determining the name of each secret type, selecting the display control of each secret type, and associating the secret level with the input secret type content (corresponding to the associated secret level 2 in fig. 4), thereby establishing the association relationship among the secret reference, the secret level, and the secret type. Through the scheme, each user can define the secret-determining basis, the secret level and the secret type in a self-defined mode, and the requirement that different users have different secret-determining basis, secret level and secret type is met, so that the scheme has universality for processing secret-related documents.

In summary, in the document encryption method provided by the embodiment of the present application, a plurality of secret levels are configured; configuring a plurality of secret bases and associating each secret base with a corresponding secret level; configuring a plurality of secret types, and associating each secret type with a corresponding secret grade to establish an association relation of a secret determination basis, the secret grade and the secret type; and carrying out encryption processing on the document according to the association relation of the encryption basis, the secret level and the encryption type. The problem of lower processing efficiency of document encryption in the related art is solved. By establishing the association relationship among the encryption basis, the secret level and the secret type, the document is encrypted according to the association relationship among the encryption basis, the secret level and the secret type, by associating the secret level according to the secret rating and the multilayer association relation of the secret type according to the secret rating, a user can conveniently carry out multistage screening based on the multilayer association relation so as to obtain the correct secret determination basis, secret level and secret type, the method has the advantages that the document is subjected to encryption, the problem that the encryption of the document fails due to the fact that encryption bases, secret levels and secret types do not correspond to each other is solved, the problem that the encryption can only be correctly performed due to the fact that a user needs to try a combination of multiple encryption bases, secret levels and secret types is solved, the times of encryption of the document are reduced, the effect of improving the processing efficiency of the encryption of the document is achieved, and software and hardware resources used by the encryption of the document are saved.

Fig. 5 is a flowchart of a document encryption method according to the second embodiment of the present application. As shown in fig. 5, the method comprises the steps of:

step S501, responding to a first selection instruction input by a user, and selecting a density determining basis for marking the density of the document to be marked from a plurality of density determining bases.

Step S502, displaying the secret grade corresponding to the secret-setting basis on the display interface.

Step S503, determining the security type according to the corresponding security level according to the secret setting, and displaying the security type on the display interface.

As shown in fig. 6, if the user clicks the add control at the encryption basis and selects the encryption basis of the document to be encrypted, the display interface displays the corresponding secret level of the encryption basis and the encryption type determined according to the corresponding secret level of the encryption basis, for example, the display interface displays that the secret level is a common commercial secret, and the encryption type is: the duration of the confidentiality is 2 years.

It should be noted that, at the secret reference in the interface shown in fig. 6, the user may click the add control, add a plurality of secret references, if the user selects a plurality of secret references, determine the secret level corresponding to each secret reference, determine the secret level with the highest secret level among the secret levels corresponding to each secret reference as the target secret level, take the target secret level as the secret level corresponding to the selected plurality of secret references, and display the target secret level. For example, the user selects the secret-setting basis 1, the secret-setting basis 2, and the secret-setting basis 3, and the secret-setting basis 1 corresponds to the secret level 1, the secret-setting basis 2 corresponds to the secret level 2, and the secret-setting basis 3 corresponds to the secret level 3. The highest secret level of the secret levels 1, 2 and 3 is the secret level 1, and the secret level 1 is taken as the secret level corresponding to the selected secret basis (secret basis 1, secret basis 2 and secret basis 3), and the secret level 1 is displayed on the display interface.

And step S504, displaying the encryption result of the document on the display interface, wherein the encryption processing is carried out on the document based on the secret level displayed on the display interface and the encryption type corresponding to the secret level.

And carrying out encryption marking processing on the document according to the secret grade displayed on the display interface and the security type corresponding to the secret grade to obtain an encryption marking result of the document, generating a transparent covering layer on a display page of the document, and displaying the encryption marking result of the document on the transparent covering layer.
