在具体实施例中，贝叶斯分类算法是统计学的一种分类方法，它是一类利用概率统计知识进行分类的算法。在许多场合，朴素贝叶斯(Naïve Bayes，NB)分类算法可以与决策树和神经网络分类算法相媲美，该算法能运用到大型数据库中，而且方法简单、分类准确率高、速度快。k均值聚类算法（k-means clustering algorithm）是一种迭代求解的聚类分析算法，其步骤是，预将数据分为K组，则随机选取K个对象作为初始的聚类中心，然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。每分配一个样本，聚类的聚类中心会根据聚类中现有的对象被重新计算。这个过程将不断重复直到满足某个终止条件。终止条件可以是没有（或最小数目）对象被重新分配给不同的聚类，没有（或最小数目）聚类中心再发生变化，误差平方和局部最小。In a specific embodiment, the Bayesian classification algorithm is a classification method of statistics, which is a class of algorithms for classification using knowledge of probability and statistics. In many cases, the Naïve Bayes (NB) classification algorithm can be compared with the decision tree and neural network classification algorithm. This algorithm can be applied to large databases, and the method is simple, high classification accuracy and fast. The k-means clustering algorithm is an iterative clustering analysis algorithm. The steps are: pre-divide the data into K groups, randomly select K objects as the initial clustering centers, and then calculate The distance between each object and each seed cluster center, assigning each object to the cluster center closest to it. Cluster centers and the objects assigned to them represent a cluster. Each time a sample is assigned, the cluster center of the cluster is recalculated based on the existing objects in the cluster. This process will repeat until a certain termination condition is met. Termination conditions can be that no (or a minimum number) of objects are reassigned to different clusters, no (or a minimum number) of cluster centers change again, and the sum of squared errors is locally minimized.

在上述实施例中，所述加密模块为改进型Blowfish加密算法模块，所述改进型Blowfish加密算法模块包含加密单元、区块链节点和解密单元，其中所述加密单元的输出端与区块链节点的输入端连接，所述区块链节点的输出端和解密单元的输入端连接。In the above embodiment, the encryption module is an improved Blowfish encryption algorithm module, and the improved Blowfish encryption algorithm module includes an encryption unit, a blockchain node and a decryption unit, wherein the output end of the encryption unit is connected to the blockchain The input end of the node is connected, and the output end of the blockchain node is connected with the input end of the decryption unit.
在上述实施例中，所述加密单元中设置有预警函数和清零函数，加密单元在加密过程中通过Blowfish加密算法对传递过程中的数据信息进行加密，加密后的数据信息遇到风险数据信息时，自动启动预警函数，提示传输过程中有风险出现，当预警级别达到设置的最高级时，自动启动清零函数，将传递过程中的高风险金融数据信息清零，并将清零前的金融数据信息原路返回。In the above embodiment, the encryption unit is provided with an early warning function and a zero-clearing function, and the encryption unit encrypts the data information in the transmission process through the Blowfish encryption algorithm during the encryption process, and the encrypted data information encounters risk data information. When the pre-warning function is activated, the warning function will be automatically activated to indicate that there is a risk in the transmission process. When the pre-warning level reaches the highest level set, the clearing function will be activated automatically to clear the high-risk financial data information in the transmission process, and the data before the clearing will be cleared. Financial data information returns the same way.
在具体实施例中，Blowfish算法是通过进行64位分组的一种算法，该种加密算法的密钥能够改变其的长度，并且这是一种对称加密的算法，该种算法能够迅速的对64比特长度的字符串进行加密。Blowfish加密算法能够快速的进行加解密，并且密钥长度可变，正是因为这些特点而被人们熟知。运用Blowfish加密算法对数据进行加解密需要把整个操作过程分成两步来进行：操作进行的第一步是需要对加密算法的密钥进行预先处理，在Blowfish加密算法的设计中，它会提供Blowfish算法的源密钥-pbox和sbox，它所提供的源密钥-pbox和sbox是固定的，每个用户使用时通采用同一套的源密钥-pbox和sbox。In a specific embodiment, the Blowfish algorithm is an algorithm that performs 64-bit grouping, and the key of this encryption algorithm can change its length, and this is a symmetric encryption algorithm, which can quickly Bit-length string to encrypt. The Blowfish encryption algorithm can perform fast encryption and decryption, and the key length is variable, which is well known because of these characteristics. Using the Blowfish encryption algorithm to encrypt and decrypt data needs to divide the entire operation process into two steps: the first step of the operation is to pre-process the key of the encryption algorithm. In the design of the Blowfish encryption algorithm, it will provide Blowfish The source keys of the algorithm - pbox and sbox, the source keys - pbox and sbox provided by it are fixed, and each user uses the same set of source keys - pbox and sbox.
因此如果希望对数据进行加密，如图3所示，需要准备一个进行加密的密钥，使用这个密钥与源密钥-pbox和sbox进行相互组合，生成子密钥key_pbox和key_sbox。第二步就是通过key_pbox和key_sbox对数据进行加密。Blowfish加密算法的加密流程如图3所示。由于Blowfish是对称性加密算法，所以在解密是同样需要通过密钥预处理生成子密钥key_pbox和key_sbox，只不过利用子密钥进行加密和解密的顺序是相反的。在Blowfish加密算法中，由于其的加密密钥长度是不确定的，可以变化其的长短，虽然这给用户设计密钥时带来很大的便利，但是同时也对数据的安全性带来很大隐患。由于Blowfish加密算法在加密和解密的核心在于密钥的选择和保密上，所以需要在Blowfish加密算法密钥的选择和保密上进行改进。Therefore, if you want to encrypt the data, as shown in Figure 3, you need to prepare an encryption key, and use this key to combine with the source key-pbox and sbox to generate sub-keys key_pbox and key_sbox. The second step is to encrypt the data through key_pbox and key_sbox. The encryption process of the Blowfish encryption algorithm is shown in Figure 3. Since Blowfish is a symmetric encryption algorithm, it is also necessary to generate subkeys key_pbox and key_sbox through key preprocessing during decryption, but the order of encryption and decryption using subkeys is reversed. In the Blowfish encryption algorithm, since the length of the encryption key is uncertain, its length can be changed. Although this brings great convenience to the user when designing the key, it also brings great harm to the security of the data. big hazard. Since the core of encryption and decryption of Blowfish encryption algorithm lies in the selection and secrecy of the key, it is necessary to improve the selection and secrecy of the key of the Blowfish encryption algorithm.
如图4所示，用户A向用户B发送数据信息M需要准备Blowfish加密算法、MD5算法和用户B的RSA加密算法的公钥，准备好三种工具才能完成接下来的工作。用户A发送端需要先通过使用Blowfish加密算法对电子文件进行加密，得到公文密文；再把Blowfish加密算法的密钥通过公网接收到的RSA加密算法公钥进行加密，就会得到Blowfish密钥密文；最后通过MD5算法对公文密文进行数字签名，可以验证数据传输是否完整，由于加密的是公文密文，既是用暴力破解MD5算法，依然只能得到公文密文，依然需要在进行破解，有很大安全性。As shown in Figure 4, when user A sends data information M to user B, he needs to prepare the public key of Blowfish encryption algorithm, MD5 algorithm and user B's RSA encryption algorithm, and prepare three tools to complete the next work. The sender of user A needs to encrypt the electronic file by using the Blowfish encryption algorithm to obtain the ciphertext of the official document; then encrypt the key of the Blowfish encryption algorithm with the public key of the RSA encryption algorithm received from the public network, and then the Blowfish key will be obtained. Ciphertext; Finally, digitally sign the ciphertext of the official document through the MD5 algorithm, which can verify the integrity of the data transmission. Since the encryption is the ciphertext of the official document, even if the MD5 algorithm is brute-forced, only the ciphertext of the official document can still be obtained, and it still needs to be cracked. , with great security.
在上述实施例中，如图5所示，在上述解密单元工作方法为：In the above-mentioned embodiment, as shown in FIG. 5, the working method of the above-mentioned decryption unit is:
使用MD5算法公钥对签名块进行解密，通过哈希函数摘要实现公文密文进行比较，如果来源相同，并且未发现漏洞，则视为文件完整，不需要重新发送，如果MD5算法公钥无法实现数据解密，再启动RSA解密密算法对文件数据信息进行解密，然后输出Blowfish加密算法的密钥；最后再通过Blowfish加密算法的密钥对公文密文进行解密，则输出解密后的电子文件M。Use the MD5 algorithm public key to decrypt the signature block, and compare the official document ciphertext through the hash function digest. If the source is the same and no loopholes are found, the file is considered complete and does not need to be resent. If the MD5 algorithm public key cannot be implemented Data decryption, then start the RSA decryption encryption algorithm to decrypt the file data information, and then output the key of the Blowfish encryption algorithm; finally, decrypt the ciphertext of the official document through the key of the Blowfish encryption algorithm, and output the decrypted electronic file M.
