Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the implementation of a system applying encrypted sound communication methods between smart phones, smart watches, notebook computers, computers, and other wearable devices.
Conventionally, in order to transfer the eigenvalue of payment between devices at the time of electronic payment, it is necessary to take the inconvenience that the person manually inputs information, inputs a QR code or a bar code with a camera or sets a separate communication device such as Bluetooth .
In addition, there was an inconvenience in establishing an electromagnetic communication channel (Bluetooth, wireless LAN, etc.) in advance for short-range communication.
Accordingly, the present invention provides a method and system for securely transmitting information between a device 1 (100) and a giga-2 (130), which have built-in speakers and microphones or can use such functions through additional connection, using air as a medium The purpose of that is to do.
In the system configured by the server 170, the device 1 100 and the device 2 130, a secure communication interval is formed between the devices 160 using sound waves, 2 130 in order to transmit the information.
The range of the sound wave includes a low frequency band and a high frequency band in addition to the audible frequency band.
According to the present invention, it is possible to realize a safe and convenient information transmission system between devices.
Description
When a variety of devices are used, general methods for transmitting information between devices include a method using a radio frequency (for example, Bluetooth) and a method using a ray (for example, infrared rays) And the like.
There are methods such as wireless LAN, Bluetooth, NFC (short range communication) and so on, but they require reliable connection establishment process or initial constraint.
The method of using light is generally used for infrared communication, which has a directionality and can be difficult to use depending on the purpose.
The method of using sound is convenient because it is not easy to use in near distance because most of the devices have built-in speakers and microphones.
When there is a need to connect various devices, the use of sound is a great advantage, but the method of protecting information in transmission is very important.
Most of the information between existing devices is transmitted through servers that provide services. The voice transmission method to be used in the present invention is widely used in a human-to-human conversation and voice communication through a communication company.
There is a problem in that communication using voice is not safe in the related art. The present invention addresses this problem.
In the case where information is transmitted between devices in order to implement an electronic commerce system such as a smart phone, a smart watch, a notebook computer, a computer, and other wearable devices, a
In the voice communication channel used in the present invention, encrypted data is transmitted.
The range of the voice communication channel used in the present invention includes a general audible frequency band (20 to 20,000 Hz), a lower or higher low frequency band and a high frequency band.
According to the present invention, the difficulty of the pre-channel configuration for transmitting information between existing devices can help constitute a safe and convenient information transmission system using sound waves in the future.
Fig. 1 is a diagram showing the entire configuration of a device-
1 is a general configuration diagram of a device-to-device information delivery system equipped with a microphone and a speaker.
The device 1 (100) transmits 'information' to the device 2 (130) for various purposes. At this time, an encrypted sound communication channel is used.
Decryption function for encryption key exchange and data encryption between the device 1 100 and the device 2 130 to generate an encrypted channel or the encrypted value provided by the device 1 100 to the device 2 130, and then the device-2 130 performs decoding using a method or information unique to the device.
