Data storage method and device

Abstract

The invention provides a data storage method and device. The method includes the steps of receiving to-be-encrypted data and determining the access level of the data; encrypting the to-be-encrypted data; storing the encrypted data, the access level of the data and identifier information of keys adopted during data encryption.

Description

technical field [0001] The present application relates to the technical field of data desensitization, and in particular to a data storage method and device, computing equipment and storage media. Background technique [0002] At present, enterprises widely use distributed systems to store and analyze business data offline, and user data in business data is the most sensitive and confidential. Enterprises not only need to prevent hackers from intruding, but also need to beware of illegal operations by internal personnel. [0003] In general, offline data query frameworks are widely used by enterprises, for example, the Hive framework is adopted, but Hive itself does not have data encryption methods, and since the Hive system does not directly provide encryption and permission control methods, the storage and access of sensitive data The use brings a lot of inconvenience. In the prior art, the permissions in Hive are at the table level, but in actual situations, different fie...

AI Technical Summary

Problems solved by technology

[0003] Under normal circumstances, the offline data query framework is widely used by enterprises, for example: the Hive framework is adopted, but Hive itself does not have data encryption methods, and because the Hive system does not directly provide encryption and permission control methods, the storage and access of sensitive data The use brings a lot of inconvenience. In the existing technology, the permissions in Hive are at the table level, but in actual situations, different fields of a table have different permissions for different people, so it cannot meet the needs of enterprises.
