Application Server Validation Using Public-Private Key Pairs

The patent introduces an application server as an intermediary between user devices and the database. The application server validates session tokens and manages authentication, preventing direct authentication calls to the database. This mediator handles the authentication bottleneck by processing validation requests locally rather than requiring database involvement for every API call, thus maintaining security while improving system efficiency.

The authentication process is segmented into two distinct phases: initial authentication at the database (which establishes a session token) and subsequent validation at the application server (which uses the session token). This segmentation separates the heavy authentication workload from the database, allowing the database to focus on data operations while the application server handles validation, thereby resolving the contradiction between security and efficiency.

The patent implements preliminary validation of the session token at the application server before establishing any database connection. The application server verifies the authenticity and validity of the session token in advance, ensuring that only authenticated user devices can proceed to establish database connections. This preliminary security check prevents malicious attacks while maintaining ease of operation for legitimate users.

The application server performs preliminary anti-action by validating the session token and blocking unauthorized access attempts before they can reach the database. By checking the authenticity of the connection request in advance and rejecting invalid sessions, the system prevents potential malicious attacks while allowing legitimate connections to proceed smoothly, thus resolving the security-ease of operation contradiction.
