Fig. 1 is a schematic diagram of an application scenario of an information encryption method according to some embodiments of the present disclosure.
In the application scenario of fig. 1, first, the computing device 101 may obtain a set of files to be parsed 102 from a preset database in response to detecting information characterizing a file selection request. The file to be parsed in the file set 102 to be parsed includes a file identifier and a field information group to be parsed corresponding to the file identifier, and the field information to be parsed in the field information group to be parsed includes a field name and a field attribute value. Secondly, the computing device 101 may perform clustering processing on each to-be-analyzed field information included in the to-be-analyzed file set 102 according to the field names included in the to-be-analyzed file set 102, so as to obtain a clustered field information group set 103. Next, the computing device 101 may select at least one cluster field information from the cluster field information group 103 as a target cluster field information set 106 according to the preset field comparison information table 104 and the preset file identification table 105. Then, the computing device 101 may perform clustering processing on the target cluster field information set 106 according to the file identifier corresponding to the target cluster field information in the target cluster field information set 106, so as to obtain a target cluster field information group set 107. Then, the computing device 101 may determine the file to be parsed corresponding to each target cluster field information group in the target cluster field information group set 107 as a target file, so as to obtain a target file group 108. Finally, the computing device 101 may perform encryption processing on the target file group 108 according to a preset replacement encryption field table, so as to obtain an encrypted target file group 109.
The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
It should be understood that the number of computing devices in FIG. 1 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.
With continued reference to fig. 2, a flow 200 of some embodiments of an information encryption method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The information encryption method comprises the following steps:
In some embodiments, an executing entity of the information encryption method (e.g., the computing device 101 shown in fig. 1) may obtain the set of files to be parsed from the preset database through a wired connection manner or a wireless connection manner in response to detecting the information characterizing the file selection request. The files to be analyzed in the file set to be analyzed comprise file identifications and field information groups to be analyzed corresponding to the file identifications. The field information to be analyzed in the field information group to be analyzed comprises a field name and a field attribute value. Here, the preset database may refer to a local database. Here, the information characterizing the file selection request may refer to a file selection instruction acting on the set of files to be parsed. Here, the file identifier may be a user identifier characterizing the file to be parsed. Here, the field attribute value may refer to a numeric type of attribute value. Here, the field names in the field information group to be parsed may include, but are not limited to, at least one of: the number of engineers, the number of transport vehicles.
As an example, the set of files to be parsed may be:
[ AA users ] - { [ engineer number: 18 ]; [ number of transport vehicles: 12] };
[ BB Users ] - { [ Engineers quantity: 20 ]; [ number of transport vehicles: 8] };
[ CC Users ] - { [ Engineers quantity: 15 ]; [ number of transport vehicles: 9] };
[ DD user ] - { [ Engineer number: 22 ]; [ number of transport vehicles: 7]}.
In some embodiments, the execution subject may group the to-be-parsed field information included in each to-be-parsed field information included in the to-be-parsed file set into one type as a cluster field information group, so as to obtain a cluster field information group set. In practice, the execution main body may extract the to-be-analyzed field information with the same field name included in each to-be-analyzed field information included in the to-be-analyzed file set through a regular expression, and then group the extracted to-be-analyzed field information with the same field name into one type as a cluster field information group.
As an example, the field information to be parsed having the same field name "number of engineers" in the file set to be parsed illustrated in step 201 may be grouped into a category as a cluster field information group "[ number of engineers: 18 ]; [ number of engineers: 20 ]; [ number of engineers: 15 ]; [ number of engineers: 22]". The field information to be resolved with the same field name "number of transportation vehicles" in the file set to be resolved exemplified in step 201 may be grouped into a category as a cluster field information group "[ number of transportation vehicles: 12 ]; [ number of transport vehicles: 8 ]; [ number of transport vehicles: 9 ]; [ number of transport vehicles: 7]". Thus, a cluster field information group set is obtained:
{ [ number of engineers: 18 ]; [ number of engineers: 20 ]; [ number of engineers: 15 ]; [ number of engineers: 22] };
{ [ number of transport vehicles: 12 ]; [ number of transport vehicles: 8 ]; [ number of transport vehicles: 9 ]; [ number of transport vehicles: 7]}.
And 203, selecting at least one clustering field information from the clustering field information group set as a target clustering field information set according to a preset field comparison information table and a preset file identification table.
In some embodiments, the execution subject may select at least one piece of cluster field information from the cluster field information group set as a target cluster field information set according to a preset field comparison information table and a preset file identification table. Here, the field comparison information in the field comparison information table includes a field comparison name and a field interception attribute value. Here, the field interception attribute value may refer to an attribute value of a numeric type. Here, the preset file identification table may be a preset table in which file identifications are stored.
In practice, the executing entity may select at least one cluster field information from the cluster field information group set as a target cluster field information set by the following steps:
first, selecting the cluster field information with the file identification corresponding to the cluster field information as the first cluster field information from the cluster field information group set, and obtaining a first cluster field information set. For example, the file identification table may be:
| file identification |
| BB user |
| CC user |
And secondly, executing the following processing steps for each first clustering field information in the first clustering field information set:
a first substep of determining whether or not a field attribute value included in the first cluster field information is greater than or equal to a field interception attribute value of field comparison information having a field name identical to a field name included in the first cluster field information. For example, the first cluster field information may be [ number of transport vehicles: 12]. The field comparison information table may be:
| name of field comparison | Field intercept attribute values |
| Number of engineering personnel | 18 |
| Number of transport vehicles | 8 |
The field comparison information whose field name included in the field comparison information table is the same as the field name included in the first cluster field information may be [ number of transport vehicles: 8].
And a second sub-step of determining the first cluster field information as second cluster field information in response to determining that the first cluster field information is equal to or greater than the second cluster field information.
And thirdly, taking the determined second clustering field information as a target clustering field information set.
In some optional implementation manners of some embodiments, according to a preset field comparison information table and a preset file identification table, the executing entity may select at least one piece of cluster field information from the cluster field information group set as a target cluster field information set by:
step one, for each cluster field information group in the cluster field information group set, executing the following selection steps:
a first substep of selecting, from the field comparison information table, field comparison information including a field comparison name identical to a field name corresponding to the clustered field information group as target field comparison information. For example, the cluster field information set may be "{ [ number of transport vehicles: 12 ]; [ number of transport vehicles: 8 ]; [ number of transport vehicles: 9 ]; [ number of transport vehicles: 7]}". The field name corresponding to the cluster field information group is 'number of transport vehicles'. Thus, the field comparison information including the field comparison name identical to the field name "number of transport vehicles" can be selected as the target field comparison information from the above-described field comparison information table.
And a second substep of selecting the cluster field information with the field attribute value greater than or equal to the field interception attribute value included in the target field comparison information from the cluster field information group as alternative field information to obtain an alternative field information group.
And secondly, according to the file identification corresponding to the alternative field information in the selected alternative field information group, clustering each alternative field information included in the selected alternative field information group to obtain an alternative clustered field information group set. In practice, the execution subject may group the candidate field information with the same file identifier in the selected candidate field information group into one type as a candidate clustering field information group, so as to obtain a candidate clustering field information group set.
And thirdly, in response to the fact that the candidate cluster field information groups with the number of the candidate cluster field information included in the candidate cluster field information group being the same as the preset number exist in the candidate cluster field information group set, selecting the candidate cluster field information groups with the number of the candidate cluster field information included in the candidate cluster field information group being the same as the preset number from the candidate cluster field information group set as a first cluster field information group, and obtaining a first cluster field information group set. Here, the preset number may refer to the number of the field information to be parsed included in the field information group to be parsed. For example, the set of candidate cluster field information groups may be "{ [ number of engineers: 18 ]; [ number of transport vehicles: 12] }; { [ number of engineers: 20 ]; [ number of transport vehicles: 8] }; { [ number of engineers: 22]}". The preset number may be "2". Therefore, an alternative cluster field information group with the number of alternative cluster field information included in the alternative cluster field information group being the same as the preset number "2" can be selected from the alternative cluster field information group set as a first cluster field information group, and a first cluster field information group set "{ [ number of engineering staff: 18 ]; [ number of transport vehicles: 12] }; { [ number of engineers: 20 ]; [ number of transport vehicles: 8]}".
And fourthly, responding to the clustering field information corresponding to the file identification table in the clustering field information group set, and selecting the clustering field information corresponding to the file identification table from the clustering field information group set as second clustering field information to obtain a second clustering field information group. In practice, the execution subject may select, from the cluster field information group, cluster field information having a file identifier corresponding to the cluster field information and the same as the file identifier in the file identifier table as second cluster field information, to obtain a second cluster field information group.
And fifthly, combining each first clustering field information included by the first clustering field information group set and each second clustering field information included by the second clustering field information group to obtain a combined clustering field information set as a target clustering field information set. Here, the combining process may refer to a splicing process.
Therefore, comprehensive comparison of field names of the same type is achieved, the time for screening the files is shortened, and the efficiency of file screening is improved.
And 204, clustering the target clustering field information set according to the file identification corresponding to the target clustering field information in the target clustering field information set to obtain a target clustering field information set.
In some embodiments, the executing entity may group, into one class, the target cluster field information having the same file identifier as the target cluster field information in the target cluster field information set, to obtain a target cluster field information group set.
In some embodiments, the executing entity may determine, as a target file, a file to be parsed corresponding to each target cluster field information group in the target cluster field information group set, to obtain a target file group.
And step 206, encrypting the target file group according to a preset replacing encryption field table to obtain an encrypted target file group.
In some embodiments, the execution main body may perform encryption processing on the target file group according to a preset replacement encryption field table to obtain an encrypted target file group. Here, the replacement encrypted field table may include field names and replacement field names corresponding to the field names. In practice, the execution main body may replace a field name included in each target file in the target file group with a replacement field name corresponding to the field name in the replacement encryption field table to generate a replaced target file, which is used as the encryption target file, so as to obtain the encryption target file group. Thereby, the encryption of the above-described target file group is completed.
The above embodiments of the present disclosure have the following advantages: through the information encryption method of some embodiments of the present disclosure, the time for screening files is shortened, and particularly, a large amount of time is consumed because: the manual review has certain subjectivity, and when the selected files cannot meet the engineering construction requirements, the files need to be screened repeatedly, so that a large amount of time is consumed. Based on this, in the information encryption method of some embodiments of the present disclosure, first, in response to detecting information representing a file selection request, a set of files to be parsed is obtained from a preset database. The file to be analyzed in the file set to be analyzed comprises a file identifier and a field information group to be analyzed corresponding to the file identifier, and the field information to be analyzed in the field information group to be analyzed comprises a field name and a field attribute value. Therefore, data support is provided for subsequent file screening. Secondly, according to the field names included in the file set to be analyzed, clustering processing is carried out on each field information to be analyzed included in the file set to be analyzed, and a clustering field information group set is obtained. Therefore, the field information of the same type can be conveniently screened subsequently, and the screening time is preliminarily shortened. And then, selecting at least one piece of clustering field information from the clustering field information group set as a target clustering field information set according to a preset field comparison information table and a preset file identification table. Therefore, the information table and the file identification table can be compared according to the preset fields, the clustering field information can be selected, and the subjectivity of manual examination is avoided. And then, according to the file identification corresponding to the target clustering field information in the target clustering field information set, clustering the target clustering field information set to obtain a target clustering field information set. And then, determining the file to be analyzed corresponding to each target clustering field information group in the target clustering field information group set as a target file to obtain a target file group. Therefore, the target file meeting the engineering construction requirements can be selected, repeated screening of the bid files is avoided, and the time for screening the files is shortened. And finally, according to a preset replacing encryption field table, encrypting the target file group to obtain an encrypted target file group. Therefore, the target file group is encrypted, and the safety of the target file group is improved.
With further reference to fig. 3, a flow 300 of further embodiments of an information encryption method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The information encryption method comprises the following steps:
And 303, selecting at least one piece of clustering field information from the clustering field information group set as a target clustering field information set according to a preset field comparison information table and a preset file identification table.
And 304, clustering the target clustering field information set according to the file identification corresponding to the target clustering field information in the target clustering field information set to obtain a target clustering field information group set.
In some embodiments, the specific implementation manner and technical effects of steps 301 and 305 may refer to steps 201 and 205 in those embodiments corresponding to fig. 2, which are not described herein again.
In some embodiments, an execution subject of the information encryption method (for example, the computing device 101 shown in fig. 1) may perform the following encryption processing steps for each target file in the target file group according to a preset replacement encryption field table:
first, each field name included in the target file is replaced with a replacement field name corresponding to the field name in the replacement encrypted field table.
And secondly, performing discrete encryption processing on each field attribute value in the replaced target file. Here, the discrete encryption process may refer to discrete logarithm encryption.
In some embodiments, the execution subject may store the encrypted target file group in a local database for subsequent invocation.
And 308, controlling the associated alarm equipment to alarm in response to the detection that the decryption request acting on the encrypted target file group fails and the number of times of the decryption request failure in the preset time length is greater than or equal to a preset threshold value.
In some embodiments, the execution subject may control an alarm device associated with the execution subject to perform an alarm operation in response to detecting that the decryption request applied to the encryption target file group fails and that the number of times of the decryption request failures within a preset time period is greater than or equal to a preset threshold. In practice, the execution main body may control the alarm device associated with the execution main body to perform alarm prompt tone reporting in response to detecting that the decryption request operation applied to the encryption target file group is unsuccessful and that the number of times of decryption request failures within a preset time period "1 minute" is greater than or equal to a preset threshold value "3 times".
The related content in step 306-308 serves as an inventive point of the present disclosure, thereby solving the technical problem mentioned in the background art that "because the file has sensitivity, the file is not encrypted, which may cause alteration or leakage of the bidding file information, and reduce the confidentiality and security of the file". Factors that reduce the confidentiality and security of a file tend to be as follows: because the file has sensitivity, the file is not encrypted, so that the file information can be changed or leaked, and the confidentiality and the safety of the file are reduced. If the factors are solved, the effect of improving the confidentiality and the safety of the file can be achieved. To achieve this effect, according to the present disclosure, first, each field name included in the target file is replaced with a replacement field name corresponding to the field name in the replacement encrypted field table. Thereby, encryption of the field name is completed. Then, discrete encryption processing is carried out on each field attribute value in the replaced target file. Thereby, encryption of the field value is completed. In addition, the field name and the field attribute value are encrypted in different modes, so that the confidentiality and the safety of the target file are greatly improved. And finally, controlling the associated alarm equipment to alarm in response to the detection that the decryption request acting on the encrypted target file group fails and the number of times of the decryption request failure in the preset time length is greater than or equal to a preset threshold value. Thereby, the possibility that the encryption target file group is cracked is reduced.
As can be seen from fig. 3, compared with the description of some embodiments corresponding to fig. 2, the process 300 of the information encryption method in some embodiments corresponding to fig. 3 first replaces each field name included in the target file with a replacement field name corresponding to the field name in the replacement encryption field table. Thereby, encryption of the field name is completed. Then, discrete encryption processing is carried out on each field attribute value in the replaced target file. Thereby, encryption of the field value is completed. In addition, the field name and the field attribute value are encrypted in different modes, so that the confidentiality and the safety of the target file are greatly improved. And finally, controlling the associated alarm equipment to alarm in response to the detection that the decryption request acting on the encrypted target file group fails and the number of times of the decryption request failure in the preset time length is greater than or equal to a preset threshold value. Thereby, the possibility that the encryption target file group is cracked is reduced.
