QR DYNAMIC QR CODE BASED ELEVATOR SECURITY SYSTEM

摘要

The present invention relates to a dynamic QR code-based elevator security system, a QR code display device that generates and displays an elevator unique QR code including elevator information and timestamp information, and the elevator unique QR code displayed on the QR code display device. Recognizes and transmits the recognized QR code unique to the elevator to generate an elevator unique QR code including a user terminal requesting elevator use authentication, and elevator information and timestamp information, and receives the elevator specific QR code from the user terminal And an authentication server that performs the elevator use authentication through transaction processing with the generated elevator-specific QR code and activates the elevator call operation when the use authentication is completed. Accordingly, the present invention makes it impossible to duplicate and hack through a dynamic QR code having real-time synchronization, thereby reinforcing security authentication according to the use of an elevator.
