Problems solved by technology

The biggest problem with sound waves is safety, which is also the price to be paid for the convenience of air transmission. It is easy to be copied by "recording", which greatly limits sound waves as a means of communication for safe data transmission, and can only be used For local applications that are not sensitive to data security

Embodiment Construction

[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments of the present invention are only used to illustrate the present invention and are not intended to limit the protection scope of the present invention.

[0057] figure 2 A sound wave or audio transmission system diagram summarizes the typical architecture of this technical solution. exist figure 2 The middle data pre-processing module (1) performs safe packaging processing on the data, and then converts it into an audio sound file (Mp3, Wav, etc.) through sound wave coding modulation (2). The audio decoding player or related program components (3) can transmit the modulated audio signal to the speaker (4a) for playback, and the receiving end Mic (5) collects the incoming sound wave and converts it into an audio signal and sends it to the audio collection The transfer process of the module (8) can also be directly transferred to t...

Abstract

The present invention discloses an apparatus, a system and a method for short-range sound wave communication. The system realizes non-contact secure transmission by using the sound wave as the data transmission medium, and also can realize a reliable and secure data link directly through an audio connection. The invention systematically constructs multiple end-to-end transmission verification mechanisms for the process of data transmission: transmission data integrity verification, valid time verification, password verification, service data verification and data encryption; and according to the security level of the data, the sending end specifies the requirements for encryption and data verification in the transmission data so as to notify the reception end which verifications should be performed to the data packets, how to perform the verifications, etc. By using the same verification processing manner, operations can be performed to the data (e.g. the payment and settlement function of an account). With lower cost, the present invention can realize the reliable communication of a small data volume using sound wave, and has certain security.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a device system and method using sound waves or audio as short-distance, safe and reliable data communication media. The invention can use sound waves to realize reliable communication with small amount of data under the condition of relatively low cost, and has certain security. Background technique [0002] Currently widely used near-field communication technologies are Bluetooth (Bluetooth), infrared data transmission (IrDA), near-field communication (Near Field Communication, NFC short-distance wireless transmission), and radio frequency identification (RFID), all of which are implemented using electromagnetic wave technology. Bluetooth technology requires human participation in the connection establishment process, and is not suitable for applications that require fast transmission (such as settlement and payment, etc.), and the chip is expensive and the anti-in...
