Embodiment

[0039] An embodiment of the visible light control access control method with hidden channel of the present invention is as follows:

[0040] (1) Establish a visible light-controlled access control device with a hidden channel, including: a mobile unlocking terminal 9 and a light-controlled access control lock 12 .

[0041]The mobile unlocking terminal 9 includes: a light emitting module 8 , a display scanning module 7 , a control module 10 , and an optical key receiving module 14 .

[0042] The light emitting module 8 is used to send the light signal 11 of the identity information of the mobile unlocking terminal 9 and the authentication information of unlocking, and the function of this module is realized by LED.

[0043] The display scanning module 7 is used for scanning and receiving the two-dimensional code displayed by the display module 4 of the light-controlled access control lock 12, and the function of this module is realized by a two-dimensional code scanning head. ...

Abstract

The invention discloses a visible light-activated access control method with a hidden channel. A visible light-activated access control apparatus with a hidden channel is established that comprises a light-operated access control lock and a mobile unlocking terminal; unlocking is controlled via mutual certification between the lock and the terminal. The hidden channel is established with a backlight module and a light key receiving module, and key light signals are transmitted via lighting backlight. The light-operated access control lock certificates validity of the moving unlocking terminal via light information transmitted by a light transmitting module, so that an illegal mobile unlocking terminal is avoided trying to unlock the access control. The mobile unlocking terminal certificates the validity of the light-operated access control lock jointly via graphic symbols of a display module and hidden key backlight signals of the backlight module, thereby preventing a fake light-operated access control lock from intercepting user information and from cracking an unlock password. By using the method, possible safety hazards of the prior art, such as information intercepting, are avoided partly, and both safety and privacy are further improved.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a visible light control access control method 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-controll...
