在一具体实施例中，从文件内容中提取财务相关的关键词时，具体可以为：In a specific embodiment, when extracting financial-related keywords from the file content, the specific method may be:
设置多个不交叉的关键词字数区间，每个关键词字数区间对应一有关键词不重合的关键词数据库；其中，不同的关键词数据库中包含的关键词不重复；每个关键词字数区间对应的关键词数据库中的关键词的字数属于该关键词字数区间；A plurality of non-intersecting keyword word count intervals are set, and each keyword word count interval corresponds to a keyword database with non-overlapping keywords; among them, the keywords contained in different keyword databases are not repeated; each keyword word count interval The word count of the keywords in the corresponding keyword database belongs to the keyword word count interval;
按照关键词字数区间从大到小的顺序确定每一轮提取选用的筛选窗口的大小，并确定每一轮提取选用的关键词数据库；其中，每一轮提取选用的筛选窗口大小指的是扫描的字数等于该轮关键词字数区间的上限；Determine the size of the screening window selected for each round of extraction in descending order of the keyword word count interval, and determine the keyword database selected for each round of extraction; wherein, the size of the screening window selected for each round of extraction refers to the scanning The number of words is equal to the upper limit of the keyword range of this round;
每一轮提取时，通过选用的筛选窗口对文件内容进行扫描，并将扫描到的信息与该轮选用的关键词数据库中的关键词进行比对，以对文件内容进行财务关键词提取；In each round of extraction, the file content is scanned through the selected screening window, and the scanned information is compared with the keywords in the keyword database selected in this round to extract financial keywords from the file content;
每完成一轮提取后，将提取出的关键词从文件内容中去除形成新的文件内容作为下一轮提取的文件内容。After each round of extraction is completed, the extracted keywords are removed from the file content to form a new file content as the file content of the next round of extraction.
当完成所有轮次的关键词提取后，将提取出的所有关键词合并组成关键词集合。After all rounds of keyword extraction are completed, all the extracted keywords are combined to form a keyword set.
例如，设置三个关键词字数区间：第一关键词字数区间的字数为(10,14]，对应有第一关键词数据库；第二关键词字数区间的字数为（6,10]，对应有第二关键词数据库；第三关键词字数区间的字数为（0,6]，对应有第三关键词数据库；For example, set three keyword word count intervals: the word count of the first keyword word count interval is (10,14], corresponding to the first keyword database; the second keyword word count interval is (6,10], corresponding to The second keyword database; the number of words in the third keyword word count interval is (0,6], corresponding to the third keyword database;
由于设置三个关键词字数区间，因此需要对文件内容进行三次关键词提取。第一轮关键词提取时，采取第一关键词字数区间的字数上限14作为筛选窗口的大小；第二轮关键词提取时，采取第二关键词字数区间的字数上限10作为筛选窗口的大小；第三轮关键词提取时，采取第三关键词字数区间的字数上限6作为筛选窗口的大小。Since three keyword word count intervals are set, it is necessary to perform keyword extraction on the file content three times. During the first round of keyword extraction, the upper limit of the number of words in the first keyword word count interval of 14 is taken as the size of the screening window; during the second round of keyword extraction, the upper limit of the word count of the second keyword word count interval of 10 is taken as the size of the screening window; During the third round of keyword extraction, the upper limit of the word count of the third keyword word count interval of 6 is taken as the size of the screening window.
基于本发明的基于加密的财务信息化数据处理处理方法的第一实施例，本发明的基于加密的财务信息化数据处理处理方法的第二实施例中，所述方法，还包括：Based on the first embodiment of the encryption-based financial informatization data processing method of the present invention, and in the second embodiment of the encryption-based financial informatization data processing method of the present invention, the method further includes:
步骤S80，建立神经网络模型；Step S80, establishing a neural network model;
步骤S90，将预设的关键词作为输入数据，将预设的关键词对应的密级作为输出数据，带入所述密级划分模型进行训练，以得到训练好的密级划分模型。In step S90, the preset keywords are used as input data, and the density levels corresponding to the preset keywords are used as output data, and are brought into the density level division model for training, so as to obtain a trained density level division model.
具体的，密级划分模型为
i从1开始取值，且i为正整数，
在选取关键词作为输入数据时，要需充分考虑到关键词的近义词和同义词。When selecting keywords as input data, it is necessary to fully consider the synonyms and synonyms of keywords.
基于本发明的基于加密的财务信息化数据处理处理方法的第一实施例或第二实施例，本发明的基于加密的财务信息化数据处理处理方法的第三实施例中，所述加密系统还包括一组具有设定顺序的解密终端，所述解密终端与所述秘钥模块信号连接；所述在一致时，识别用户权限对应的密级，根据用户权限对应的密级，将财务文件中密级符合的区块状态调整为可读区块，并将财务文件中密级不符合的区块保持不可读状态的步骤之后，还包括：Based on the first or second embodiment of the encryption-based financial informatization data processing method of the present invention, and in the third embodiment of the encryption-based financial informatization data processing method of the present invention, the encryption system further It includes a group of decryption terminals with a set order, and the decryption terminals are signal-connected with the secret key module; when they are consistent, identify the secret level corresponding to the user authority, and match the secret level in the financial file according to the secret level corresponding to the user authority. After the steps of adjusting the state of the block to be readable, and keeping the block in the financial file in an unreadable state that does not meet the confidentiality level, it also includes:
步骤S100，在所述不可读区块显示秘钥输入窗；具体的，可读区块中直接显示该区块对应的文件内容，以便于用户查阅；不可读区块设置为不可访问状态，并在用户点击不可读区块时，显示秘钥输入窗。Step S100, displaying a key input window in the unreadable block; specifically, directly displaying the content of the file corresponding to the block in the readable block, so as to facilitate user inspection; the unreadable block is set to an inaccessible state, and When the user clicks on the unreadable block, the key input window is displayed.
步骤S110，当所述区块的秘钥输入窗被点击时，向所述秘钥模块发送所述区块的解密指令；具体的，当秘钥输入窗被点击时，才向秘钥模块发送该区块的解密指令，以保证不可读区块的解密秘钥是随机生成的，而不是预设的，这是因为，预设秘钥往往容易泄露而造成财务数据处于容易窃取的不安全状态。Step S110, when the key input window of the block is clicked, send the decryption instruction of the block to the key module; specifically, when the key input window is clicked, send the decryption instruction to the key module. The decryption instruction of the block is to ensure that the decryption key of the unreadable block is randomly generated, not preset. This is because the preset secret key is often easily leaked and financial data is in an insecure state that is easy to steal. .
步骤S120，所述秘钥模块根据所述区块对应的密级，确定多个解密终端以形成解密终端集合，并向所述解密终端集合中的各个解密终端发送秘钥段，其中，将各个所述解密终端接收到的秘钥段按照解密终端顺序拼接，以得到所述区块的解密秘钥；此处的确定多个解密终端形成解密终端集合中，多个解密终端指的是至少两个解密终端，而多个解密终端的个数，可以根据区块的密级确定。例如，密级较低时，确定两个解密终端即可，密级较高时，确定个数更多的解密终端。Step S120, the secret key module determines a plurality of decryption terminals to form a decryption terminal set according to the encryption level corresponding to the block, and sends a secret key segment to each decryption terminal in the decryption terminal set, wherein each The key segments received by the decryption terminal are spliced in the order of the decryption terminals to obtain the decryption key of the block; here it is determined that multiple decryption terminals form a decryption terminal set, and multiple decryption terminals refer to at least two Decryption terminals, and the number of multiple decryption terminals can be determined according to the encryption level of the block. For example, when the secret level is low, two decryption terminals may be determined, and when the secret level is high, a larger number of decryption terminals may be determined.
多个解密终端分别接收到秘钥段拼接成解密秘钥，有利于提高秘钥的安全性。例如，即使其中一秘钥终端的秘钥段被拦截，也无法破解多个秘钥终端的多个秘钥段组成的解密秘钥。A plurality of decryption terminals respectively receive the secret key segments and spliced into a decryption secret key, which is beneficial to improve the security of the secret key. For example, even if the key segment of one key terminal is intercepted, the decryption key composed of multiple key segments of multiple key terminals cannot be cracked.
进一步的，解密秘钥发送至用户终端，具体的，各个解密终端具有预设顺序代码，按照解密终端集合中各个解密终端的顺序代码，控制解密终端集合中的各个解密终端按照次序向关联的用户终端发送密码段，在用户终端中拼接对应的密码段，即可得到解密秘钥。其中，为了避免密码段拼接顺序错误，在向用户终端发送密码段时，还同步发送各个密码段的顺序。以使用户根据密码段的顺序可以自行拼接密码段。Further, the decryption key is sent to the user terminal. Specifically, each decryption terminal has a preset sequence code, and according to the sequence code of each decryption terminal in the decryption terminal set, each decryption terminal in the decryption terminal set is controlled to the associated user in order. The terminal sends the password segment, and the corresponding password segment is spliced in the user terminal to obtain the decryption key. Wherein, in order to avoid the wrong order of splicing the password segments, when the password segments are sent to the user terminal, the sequence of each password segment is also sent synchronously. So that users can splicing password segments by themselves according to the sequence of the password segments.
步骤S130，当侦测到所述解密秘钥输入所述秘钥输入窗时，将所述区块调整为可读区块。Step S130, when it is detected that the decryption key is input into the key input window, adjust the block to a readable block.
进一步的，所述秘钥模块连接有多个财务模块，每个财务模块可以与解密终端建立固定的对应关系或者随机的对应关系。在本实施例中，每个财务模块关联一组专用的解密终端。而所述秘钥模块根据所述区块对应的密级，确定多个解密终端以形成解密终端集合的过程中，根据解密终端的需求数量，按照解密终端的顺序代码依次确定个数足够的解密终端即可。例如，财务模块A关联的一组解密终端包括解密终端1至解密终端7，当该区块对应的密级需要3个解密终端时，则按照解密终端的顺序代码将解密终端1至解密终端3形成解密终端集合即可。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. In the process of determining a plurality of decryption terminals to form a decryption terminal set according to the encryption level corresponding to the block, the secret key module sequentially determines a sufficient number of decryption terminals according to the required number of decryption terminals and the sequence code of the decryption terminals That's it. For example, a group of decryption terminals associated with financial module A includes decryption terminal 1 to decryption terminal 7. When three decryption terminals are required for the encryption level corresponding to the block, decryption terminal 1 to decryption terminal 3 are formed according to the sequence code of the decryption terminals. Decrypt the terminal set.

The key pool; the step of determining a plurality of decryption terminals to form a decryption terminal set by the secret key module according to the secret level corresponding to the block, and sending a secret key segment to each decryption terminal in the decryption terminal set, including:
步骤S121，秘钥模块根据所述区块对应的密级，确定多个解密终端以形成解密终端集合；Step S121, the key module determines a plurality of decryption terminals to form a decryption terminal set according to the encryption level corresponding to the block;
步骤S122，随机建立所述解密终端集合中的各个解密终端与所述秘钥池的对应关系，且每个所述解密终端集合中的各个解密终端对应的秘钥池不同；Step S122, randomly establishing a correspondence between each decryption terminal in the decryption terminal set and the secret key pool, and the secret key pool corresponding to each decryption terminal in each of the decryption terminal sets is different;
步骤S123，从所述解密终端建立对应关系的所述秘钥池中提取秘钥段，并向对应的解密终端发送秘钥段。Step S123: Extract the secret key segment from the secret key pool in which the decryption terminal establishes a corresponding relationship, and send the secret key segment to the corresponding decryption terminal.
在本实施例中，每个秘钥段来自于秘钥池中。秘钥池中预存有若干个秘钥段，而所述解密终端集合中的各个解密终端与所述秘钥池的对应关系是随机建立的，因此，能使各个秘钥段组成的解密秘钥组合的可能性更多，提高解密秘钥破解的难度，使财务文件的保密性更强。In this embodiment, each key segment comes from a key pool. Several secret key segments are pre-stored in the secret key pool, and the corresponding relationship between each decryption terminal in the decryption terminal set and the secret key pool is randomly established, so the decryption secret key composed of each secret key segment can be made. There are more possibilities of combinations, which increases the difficulty of decrypting the decryption key and makes financial documents more confidential.
