Method for two-way communication using optical visual coding

Abstract

A method for performing bidirectional communication by adopting the optical vision codes is disclosed in the present invention, and it uses two or more devices with at least one display unit and at least one electrical optical scan unit, the two or more devices can read the optical vision code on the display unit of each other by the electrical optical scan unit, in order to perform the bidirectional communication; the whole bidirectional communication process is processed once or many times; at least one of said devices determines whether the user identity of one or more devices is genuine or fake and / or determines the authorization of business payment through the bidirectional communication content and / or the detection process inside and / or outside of the device. In this operation flow of the method for processing bidirectional communication by adopting the optical vision codes in the present invention, the information transmission is very safe and is not easy to be intercepted by the exterior equipment; and because the payment or secret information transmission is performed after the identity verification, the operation safety is further ensured, and the user's property and the information safety are further ensured.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to a method for two-way communication using optical visible coding. Background technique [0002] At present, we often need to transmit information between different devices in our daily life. One of the widely used transmission methods is to transmit through wireless communication devices, but for some important or secret information, these transmission methods are not very suitable. Safe and reliable. For example, there are certain problems in the confidentiality and security of existing mobile phone wallets and radio frequency identification technology (RFID) payment systems. Because when using mobile wallets and radio frequency identification technology payment systems, it is necessary to use radio communication devices such as Bluetooth. These devices transmit information through radio signals, so that the communication content is very easy to be eavesdropped, intercept...

Problems solved by technology

Because when using mobile wallets and radio frequency identification technology payment systems, it is necessary to use radio communication devices such as Bluetooth. These devices transmit information through radio signals, so that the communication content is very easy to be eavesdropped, intercepted, tampered with or counterfeited. economic loss to users

Or when paying, the user may also receive a fake payment request, and will be deceived if he is not careful; and when using a Bluetooth mobile wallet to pay, if multiple people pay at the same time, multiple payments will be received on one mobile phone Request, at this time, the user needs to enter the corresponding transaction code to operate, which is cumbersome to use

At the same time, another problem with this type of system is that end users are usually unwilling to turn on wireless communication devices such as Bluetooth, because this may cause their physical location to be tracked by others, or they may be forced to receive spam information such as advertisements after turning on
