Database processing method, device, equipment and medium

An electronic device, comprising:

• a processor;
• and
• a memory, configured to store an executable instruction for the processor, wherein,
• the processor is configured to read the executable instruction from the memory, and when the processor executes the executable instruction, the processor is caused to:
• receive an access request for a database, wherein the access request carries a user identifier of an access party and a data processing instruction, the data processing instruction is used for instructing to process specified data in the database to obtain target data, and the database is deployed in a separate secure execution environment;
• in response to determining that the specified data is encrypted data, query an authorization information table in the database based on the user identifier of the access party, and detect whether the access party is an authorized user of the specified data, wherein the encrypted data is data stored in the database in an encrypted form, and the authorization information table is used for recording authorized user information configured by a data party for the encrypted data;
• and
• in response to determining that the access party is the authorized user of the specified data, execute the data processing instruction to process the specified data to obtain the target data, and return the target data in response to the access request.

A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program is configured to:

• receive an access request for a database, wherein the access request carries a user identifier of an access party and a data processing instruction, the data processing instruction is used for instructing to process specified data in the database to obtain target data, and the database is deployed in a separate secure execution environment;
• in response to determining that the specified data is encrypted data, query an authorization information table in the database based on the user identifier of the access party, and detect whether the access party is an authorized user of the specified data, wherein the encrypted data is data stored in the database in an encrypted form, and the authorization information table is used for recording authorized user information configured by a data party for the encrypted data;
• and
• in response to determining that the access party is the authorized user of the specified data, execute the data processing instruction to process the specified data to obtain the target data, and return the target data in response to the access request.
