Passenger Information Terminal Access Using Registered Electronic ID

The patent replaces the mechanical skeleton key system with an electronic identification system. Instead of using physical keys that can be copied and distributed, the system uses electronic identification devices (such as cards, tokens, or biometric sensors) that communicate with the interfacing system through electronic signals. This substitution eliminates the security vulnerability of skeleton keys while maintaining ease of operation, as authorized operators can still access the system conveniently using their electronic identification devices.

The patent implements a self-service electronic identification system where operators register and manage their own access credentials without requiring centralized key management infrastructure. The interfacing system automatically handles the registration of electronic identification devices and verifies authentication requests locally. This eliminates the need for complex centralized key management while maintaining secure access control, as each operator independently manages their own electronic identification device.

The patent applies local quality by creating different access conditions for different locations within the transport vehicle. The system distinguishes between public areas where passengers are present and restricted areas where only authorized operators can access. Electronic identification registration is permitted only when the system detects that the operator is in a restricted area, not in a public area. This location-based differentiation maintains security by preventing unauthorized registration in public areas while still allowing flexible registration for authorized operators in appropriate locations.
