Abstract

The invention relates to the technical field of passwords, and discloses a data encryption method and device, equipment and a storage medium. The method comprises the following steps: acquiring to-be-encrypted user original data; receiving an encryption request for original data of a user; determining a key and a key tag corresponding to the key based on the encryption request; acquiring an encryption rule corresponding to the key tag, and partitioning the key based on the encryption rule to obtain a plurality of encrypted key blocks; calling a preset symmetric encryption algorithm to convert the encrypted key blocks into character strings in a preset format, obtaining a public key of the symmetric encryption algorithm through the character strings, and encrypting the user original data through the public key to obtain initial encrypted data; and desensitizing the initial encrypted data to obtain a data encryption result. According to the invention, encryption and desensitization processing are carried out on the user data through the system level, the technical problems of data leakage and the like are solved, and the data security is improved.

Description

technical field [0001] The present invention relates to the technical field of encryption, in particular to a data encryption method, device, equipment and storage medium. Background technique [0002] With the increasing types and quantities of data, in order to avoid the loss of sensitive data such as company data and customer data due to leakage, data storage encryption technology has been widely used and has become an effective method to protect data security. Data storage encryption technology usually refers to the use of specific technology to encrypt data before writing data to the storage device, so as to ensure the security of the data stored on the storage device. Correspondingly, the corresponding technology is used when reading the stored data Decrypt the data. [0003] At present, the existing collection system is all equipped with a company's personal mobile phone for the reminder, and the reminder is not allowed to take the mobile phone out of the company. Wh...
