Methods and apparatus for authorizing validation requests for accessing data in a database. In particular, according to the present invention, a METADATA node 2 validates a request for storage location(s) and access authorization of a user at a client, and generates a token and an access token validation code. In addition, it sends to the client access authorization control information containing an access token and an access token validation code. As a result, when the client sends a request for data access to USERDATA node 2, USERDATA Node 2 can enforce access authorization for the data access request according to the access authorization control information included therein. The invention thus solves the problem that existing NoSQL databases or similar databases have not been able to provide authorization validation for data access requests, thereby improving the security of such databases. |
