Data processing method and device and computer readable storage medium

Abstract

The invention discloses a data processing method and device and a computer readable storage medium, and the method comprises the steps: receiving a data processing request sent by a terminal device, and obtaining to-be-stored data and an encryption instruction; converting the to-be-stored data into ciphertext data, and generating a secret-related security level and an identity verification code of the ciphertext data, wherein the ciphertext data, the secret-related security level of the ciphertext data and the identity verification code of the ciphertext data are stored in an associated mode, and when a data extraction instruction sent by the terminal equipment is received, a target storage identification code, a security level code and identity information of the terminal equipment are determined according to the data extraction instruction; determining the confidential security level of the to-be-extracted data according to the security level code, and screening out storage data with the same confidential security level as the to-be-extracted data; and determining ciphertext data of the to-be-extracted data according to the target storage identification code and the screened storage data, and decrypting the ciphertext data to obtain viewable to-be-extracted data. According to the invention, the security of data distributed processing can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method, device and computer-readable storage medium. Background technique [0002] The existing distributed data processing method (such as the patent of publication number CN105892953B) generally assigns a storage identification code to each independent storage device, and when receiving the data to be stored, generates a format corresponding to the storage identification code according to the data to be stored. Random number, the data to be stored is directly stored in the storage device corresponding to the storage identification code with the highest matching degree of the random number. When extracting, the data can be extracted by matching and verifying the storage identification code. However, this data processing method is easy to cause Data leakage and distributed data processing are less secure; in addition, this solution requires pre-c...

[0002] The existing distributed data processing method (such as the patent of publication number CN105892953B) generally assigns a storage identification code to each independent storage device, and when receiving the data to be stored, generates a format corresponding to the storage identification code according to the data to be stored. Random number, the data to be stored is directly stored in the storage device corresponding to the storage identification code with the highest matching degree of the random number. When extracting, the data can be extracted by matching and verifying the storage identification code. However, this data processing method is easy to cause Data leakage and distributed data processing are less secure; in addition, this solution requires pre-classification of storage devices, which seriously affects data storage. Excessive reliance on physical pre-defined things does not reflect the superiority of software algorithms
