Embodiment Construction

[0012] Two-way data security transmission scheme

[0013] After sending and receiving module 1 sends a signal. Transceiver module 2 accepts the signal but does not read it, randomly takes out a password from the password library, and sends it to transceiver module 1. After the transceiver module 1 receives the password, it uses the enumeration algorithm to find out the number of items corresponding to the password from the password library, and sends it to the transceiver module 2. The transceiver module 2 reads the signal when it receives the correct feedback, otherwise, a prompt box will pop up to report suspicious information.

[0014] The specific usage process is:

[0015] A. Connect transceiver module 1 and transceiver module 2 to the serial port respectively;

[0016] B. Open the ports separately;

[0017] C. Provide the data to be sent for transceiver module 1, and click send;

[0018] D. Obtain the received correct data in the transceiver module 2, or report a do...

Abstract

The invention discloses a bidirectional data safe transmission method based on visible light communication technology. Data are encoded by an upper computer and transmitted by a transceiver module 1.After a transceiver module 2 receives data, the transceiver module 2 performs decoding according to a serial port communication protocol, and furthermore the transceiver module 2 selects one item of data from a local password database for transmission. When the transceiver module 1 receives the password which is fed back from the transceiver module 2, an enumeration algorithm is utilized for finding out a corresponding item of the data in the password database, and furthermore the corresponding item is transmitted and fed back to the transceiver module 2. If the transceiver 2 receives the right feedback, the data are written into a computer, and otherwise, a prompt dialog box is sprung for alarming. Through executing a plurality of times of main cycles with millisecond as a unit, reading to a document tail is performed. The device used in the method is simple, and a new efficient and safe method is supplied for data transmission. A data theft or tampering risk is reduced. Furthermore an LED illuminating lamp is used as an illuminating light source, thereby saving energy.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to a two-way secure data transmission method based on visible light communication technology. Background technique [0002] White light LED has the characteristics of energy saving, reliability, long life, low price and high-speed modulation, and can realize the dual functions of lighting and visible light communication at the same time. Visible light communication has many advantages such as safety and energy saving, avoiding electromagnetic interference, high communication rate, and precise positioning. It has broad application prospects and is a research hotspot in the field of optical communication. Since Japanese researchers proposed visible light communication in 2000, after more than ten years of development, the transmission rate has become higher and higher, and breakthroughs have been made continuously. [0003] Visible light communication is currently...
