Abstract

The invention provides a method and device for transmitting hidden information by using music. The method uses the masking effect of human hearing to hide information in music for transmission, which can make the transmitted audio more pleasing to the ear and has higher security . The present invention also provides a device for realizing the above method at the same time, including two parts: a sending end and a receiving end, wherein the sending end is composed of a sending end memory, an input module, a modulator, a sound mixing module and a playback module, and the receiving end is composed of a receiving module, The synchronous module, the demodulator and the memory of the receiving end are jointly formed. The invention can be used in occasions such as mobile data sharing, initial configuration of wireless devices, control of intelligent toys and the like.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a method and device for transmitting hidden information through music. Background technique [0002] Using audio to transmit information is a new wireless data transmission technology that has emerged in recent years. The sending end modulates the information to be transmitted onto the audio and plays it with a speaker. The receiving end uses a microphone to receive the audio signal and demodulates the information sent by the sending end. . At present, the main applications of this technology include: (1) Mobile data sharing. Using audio wireless information transmission technology can easily share pictures, text, video and other data between mobile devices. For example, Chirp, a product launched by Animal Systems in the United States, can upload photos, text information, and website links and other information taken by the camera to the server. Code on the computer and...
