Abstract

The invention discloses a visible light-control access control device with a hidden channel. The device comprises a light-control access control lock and a moving unlocking terminal; the light-control access control lock is composed of a light lock receiving module, a lock control module, a controlled module, a display module, a backlight module, a communication and alarm module and a power module; the moving unlocking terminal comprises a light emission module, a light key receiving module, a display scanning module and a terminal control module. According to the visible light-control access control device with the hidden channel, access control is achieved through mutual authentication of the light-control access control lock and the moving unlocking terminal; the hidden channel is established by means of the backlight module and the light key receiving module, lighting backlight is used for transmitting a key light signal, the moving unlocking terminal is authenticated by means of light information sent by the light emission module, the light-control access control lock is authenticated by means of graphic symbols of the display module and hidden key backlight signals of the backlight module, that is to say, the situation that an illegal moving unlocking terminal attempts to open access control can be prevented, and a counterfeit light-control access control lock can be prevented from intercepting user information and cracking an unlocking password.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a visible light-controlled access control device with a hidden channel. Background technique [0002] Now lawbreakers use various methods to intercept user information and steal user property, which can be described as "every trick", such as: "phishing" websites that pretend to be banks or e-commerce platforms and steal private information such as bank account numbers and passwords submitted by users; The magnetic card reader installed in the card slot of the ATM machine and the camera at the keyboard, etc. These are things users want to avoid happening. [0003] For an access control system, both the access control terminal and the key terminal hope to avoid information forgery and identity forgery of the other party. Invention application (201310405814.9) combines VLC technology with image and graphic recognition technology and proposes a light-contr...
