Short-Range Transceiver Verification for Spoof-Resistant Messaging

The patent introduces a trusted service provider as an intermediary that issues cryptographic credentials (public-private key pairs) to user devices. This mediator enables secure verification by allowing the server to authenticate users through digitally signed messages without requiring direct trust between communicating parties, thus resolving the contradiction between remote communication convenience and identity verification reliability.

The patent replaces the mechanical/SMS-based messaging system with a cryptographic verification system. Instead of relying on SMS protocol authentication, the system uses public-key cryptography where user devices sign messages with private keys and servers verify them with corresponding public keys. This substitution eliminates spoofing vulnerabilities while maintaining ease of operation through automated cryptographic processes.

The patent applies preliminary anti-action by establishing cryptographic verification before confidential information is transmitted. The server verifies the user's identity through digitally signed messages before allowing communication, preventing unauthorized access and information compromise in advance. This preemptive security measure protects confidential information while maintaining communication convenience.
