Incoming Call Authentication Using Matched Verification Codes

The patent introduces an intermediary authentication system that mediates between callers and callees. A verification module generates unique verification codes for each call attempt, which are transmitted through the communication network to the receiving device. This intermediary mechanism prevents direct spoofing by adding a layer of authenticated verification that both parties must complete, thereby resolving the contradiction between ease of operation and authentication reliability.

The system performs preliminary authentication actions before the actual communication occurs. The verification module pre-generates authentication credentials and establishes verified communication channels in advance. By conducting authentication procedures before the main communication event, the system ensures that only authenticated participants can engage in communication, thus maintaining reliability without significantly impacting operational ease.

The authentication system implements self-service mechanisms where the verification module automatically generates, transmits, and validates verification codes without requiring manual intervention. The system autonomously manages the authentication process, including generating unique codes for each call attempt and automatically comparing them at the receiving end. This automation reduces the perceived complexity for users while maintaining high authentication reliability.

The verification module is designed as a universal component that can handle multiple authentication scenarios across different communication channels. The same module generates verification codes for various types of calls and communications, providing a multi-functional solution that reduces overall system complexity by consolidating authentication functions into a single versatile component rather than requiring separate mechanisms for each communication type.
