It should be noted that, when performing data cleaning on administrative data, error data and duplicate data may be extracted for further verification, and then the data is maintained.
And 103, encrypting the preprocessed administrative data according to the encryption level, and correspondingly storing the encrypted data in different sectors in the database.
Optionally, encrypting the preprocessed administrative data according to an encryption level in this step may include:
determining encryption levels of the preprocessed administrative data according to categories, different contents in the same category and encryption requirements;
and encrypting all administrative data to different degrees according to the encryption level.
Optionally, the encryption requirement is an encryption requirement for enterprise file prefabrication.

Optionally, MD5 can ensure the integrity and consistency of information transmission, and is one of the hash algorithms widely used by computers, which can operate on data (such as chinese characters) to another fixed length value. When the two data are completely consistent, the MD5 values respectively calculated according to the two data are the same, and when only one of the numbers or letters is different from the two data, the calculated MD5 values are also very different. Therefore, data integrity can be guaranteed by encrypting data by using MD5 values. When the administrative data is found to be maliciously tampered, it can be found immediately when MD5 is recalculated. In this embodiment, the administrative data is encrypted again according to the calculated MD5 value, and the encryption method is not limited in this case, that is, the encrypted data is obtained by secondary encryption.

Optionally, each data block is sequentially encrypted, and a ciphertext encrypted by a previous data block is used when a next data block is encrypted, so that the encrypted ciphertext has higher security.
And B, computing the data of the first data block and a preset initial vector to obtain a first computing result.
Optionally, the initial vector may be set according to requirements.
Optionally, the operation performed on the data of the first data block and the preset initial vector may include any one or more operations, such as an exclusive-or operation, an addition-subtraction operation, a square operation, and the like.
And step C, encrypting the first operation result by adopting a user-defined encryption key to obtain an encrypted ciphertext.
And D, determining preset data in the encrypted message as an initial encryption vector of the second data block according to a preset rule.
Optionally, the preset rule is a rule for determining a ciphertext as an encryption vector of the second data block, for example, a section of continuous ciphertext is selected at the beginning of the encrypted ciphertext, or a section of continuous ciphertext is selected at the end of the encrypted ciphertext, or a section of continuous ciphertext is selected in the middle of the ciphertext.
The encryption vector of the next data block is set according to the encrypted ciphertext of the previous data block, so that the risk of the ciphertext being cracked can be reduced.
And E, encrypting a second data block according to the initial encryption vector in a mode of encrypting the first data block, determining the initial encryption vector of the next data block, and encrypting the next data block until all data blocks are completely encrypted to obtain the encrypted administrative data.
Optionally, the second data block is encrypted according to the initial encryption vector, that is, the data of the second data block and the initial encryption vector are operated to obtain a second operation result. And encrypting the second operation result by adopting the user-defined encryption key to obtain a second ciphertext. And determining preset data in the encrypted message as an initial encryption vector of the second data block according to a preset rule.
Optionally, after obtaining all encrypted files, the encrypted data may be correspondingly stored in different sectors in the database according to the encryption level;
and sequentially storing the encrypted data in different sectors in the database according to the category of the administrative data and the encryption degree of the encryption level. For example, when different contents under administrative data such as enterprise-related information are encrypted by using intermediate-level encryption and high-level encryption respectively, the enterprise-related information may be stored in sectors 1 to 3 in the database, where sector 2 stores intermediate-level encryption information and sector 3 stores high-level encryption information.
According to the method for safely storing the administrative data, the administrative data are divided according to the categories, then encrypted according to the encryption level, and then correspondingly stored in different sectors in the database, the encryption mode is that the data are encrypted according to the MD5 value, and the data are encrypted in a chain encryption mode, so that the security is high, and the data are not easy to crack.
