In an embodiment, when extracting the finance-related keywords from the document content, the method may specifically be:
setting a plurality of non-crossed keyword number intervals, wherein each keyword number interval corresponds to a keyword database with non-coincident related keywords; wherein, the keywords contained in different keyword databases are not repeated; the word number of the keyword in the keyword database corresponding to each keyword word number interval belongs to the keyword word number interval;

and after each round of extraction is finished, removing the extracted keywords from the file contents to form new file contents serving as the file contents of the next round of extraction.
And after the extraction of the keywords of all rounds is finished, combining all the extracted keywords to form a keyword set.
For example, three keyword word number intervals are set: the number of words in the first keyword word number interval is (10, 14) corresponding to the first keyword database, the number of words in the second keyword word number interval is (6, 10) corresponding to the second keyword database, the number of words in the third keyword word number interval is (0, 6) corresponding to the third keyword database;
since three keyword number intervals are set, three times of keyword extraction needs to be performed on the file content. During the first round of keyword extraction, taking the upper limit 14 of the word number interval of the first keyword as the size of a screening window; when extracting the second round of keywords, taking the upper limit 10 of the word number interval of the second keyword as the size of a screening window; and in the third round of keyword extraction, taking the upper limit 6 of the number of words in the third keyword number interval as the size of the screening window.
Based on the first embodiment of the encryption-based financial information data processing method of the present invention, in the second embodiment of the encryption-based financial information data processing method of the present invention, the method further includes:
step S80, establishing a neural network model;
and step S90, taking the preset keywords as input data, taking the security classification corresponding to the preset keywords as output data, and taking the security classification into the security classification model for training to obtain a trained security classification model.
Specifically, the classified classification model is
；
i starts from 1 and is a positive integer,
the mth keyword in the content of the file whose position code is i,
，
the total number of the keywords corresponding to the keyword corresponding to the file content with the position code of i.
When selecting a keyword as input data, it is necessary to fully consider the synonyms and synonyms of the keyword.
Based on the first embodiment or the second embodiment of the encryption-based financial information data processing method of the present invention, in a third embodiment of the encryption-based financial information data processing method of the present invention, the encryption system further includes a set of decryption terminals having a set order, the decryption terminals being in signal connection with the key module; when the security level is consistent, identifying the security level corresponding to the user authority, adjusting the block state of the financial file with the security level being consistent to a readable block according to the security level corresponding to the user authority, and keeping the block of the financial file with the security level being inconsistent to an unreadable state, wherein the method further comprises the following steps:
step S100, displaying a key input window in the unreadable block; specifically, the file content corresponding to the block is directly displayed in the readable block so as to be convenient for a user to look up; the unreadable block is set to an inaccessible state, and when the user clicks the unreadable block, a key input window is displayed.
Step S110, when the key input window of the block is clicked, sending a decryption instruction of the block to the key module; specifically, when the key input window is clicked, the decryption instruction of the block is sent to the key module, so as to ensure that the decryption key of the unreadable block is randomly generated, rather than preset, because the preset key is often easily leaked, and the financial data is in an unsafe state where the financial data is easily stolen.
Step S120, the key module determines a plurality of decryption terminals to form a decryption terminal set according to the security level corresponding to the block, and sends a key segment to each decryption terminal in the decryption terminal set, wherein the key segments received by each decryption terminal are sequentially spliced according to the decryption terminals to obtain the decryption keys of the block; in the step of determining that a plurality of decryption terminals form a decryption terminal set, the plurality of decryption terminals refer to at least two decryption terminals, and the number of the plurality of decryption terminals can be determined according to the security level of the block. For example, when the security level is low, two decryption terminals may be determined, and when the security level is high, a larger number of decryption terminals may be determined.
The plurality of decryption terminals respectively receive the key segments and splice the key segments into decryption keys, and the security of the keys is improved. For example, even if the key segment of one of the key terminals is intercepted, the decryption key composed of the key segments of the key terminals cannot be decrypted.
Further, the decryption key is sent to the user terminal, specifically, each decryption terminal has a preset sequence code, each decryption terminal in the decryption terminal set is controlled to send the password segment to the associated user terminal according to the sequence code of each decryption terminal in the decryption terminal set, and the corresponding password segment is spliced in the user terminal, so that the decryption key can be obtained. In order to avoid wrong splicing sequence of the password segments, the sequence of each password segment is synchronously transmitted when the password segments are transmitted to the user terminal. So that the user can splice the password segments by himself according to the sequence of the password segments.
In step S130, when it is detected that the decryption key is input into the key input window, the block is adjusted to be a readable block.
Further, the secret key module is connected with a plurality of financial modules, and each financial module can establish a fixed corresponding relationship or a random corresponding relationship with the decryption terminal. In this embodiment, each financial module is associated with a set of dedicated decryption terminals. And the key module determines a plurality of decryption terminals to form a decryption terminal set according to the security level corresponding to the block, and sequentially determines a sufficient number of decryption terminals according to the required number of the decryption terminals and the sequence codes of the decryption terminals. For example, a group of decryption terminals associated with the financial module a includes the decryption terminals 1 to 7, and when 3 decryption terminals are required for the security level corresponding to the block, the decryption terminals 1 to 3 may form a decryption terminal set according to the sequence codes of the decryption terminals.
Based on the third embodiment of the encryption-based financial information data processing method of the present invention, in the fourth embodiment of the encryption-based financial information data processing method of the present invention, the key module is provided with different key pools; the key module determines a plurality of decryption terminals to form a decryption terminal set according to the security level corresponding to the block, and sends a key segment to each decryption terminal in the decryption terminal set, wherein the key segment includes:
step S121, the secret key module determines a plurality of decryption terminals according to the secret level corresponding to the block to form a decryption terminal set;
step S122, randomly establishing a correspondence between each decryption terminal in the decryption terminal set and the key pool, where the key pools corresponding to each decryption terminal in each decryption terminal set are different;
step S123, extracting a key segment from the key pool in which the corresponding relationship is established between the decryption terminals, and sending the key segment to the corresponding decryption terminal.
In this embodiment, each key segment is from a pool of keys. The key pool is pre-stored with a plurality of key segments, and the corresponding relationship between each decryption terminal in the decryption terminal set and the key pool is randomly established, so that the possibility of decryption key combinations formed by each key segment is higher, the difficulty of decryption key cracking is improved, and the confidentiality of financial documents is stronger.
Based on the first to fourth embodiments of the encryption-based financial information data processing method according to the present invention, in a fifth embodiment of the encryption-based financial information data processing method according to the present invention, the step of dividing the financial file into blocks with different security levels according to the security level corresponding to each position code by the financial module specifically includes:
wherein i is a position code corresponding to the file content in the financial file, the value of i is started from 1, and i is a positive integer;
the security level corresponding to the file content with the position code of i;
the security classification is the security classification corresponding to the file content with the position code of i + 1; j is the serial number of the block set, j begins to take a value from 1, and j is a positive integer;
representing the file content with the position code i;
representing the file content with the position code of i + 1;
is the jth block set;
is the j +1 block set;
indicating that the content of a file with a position code of i is added to a block set
，
Indicating that the file content with the position code of i +1 is added to the block set
；
Indicating that the content of a file with a position code of i +1 is added to a block set
；

The block set number of (2);
when in use
