Claim Text:
1. A method comprising: receiving, by one or more processors, a first file that includes a set of data representing a Quick Response (QR) Code, and a second file that includes audio data; generating, by the one or more processors, a third file, that includes the audio data of the second file where a low frequency of the audio data is attenuated, wherein the attenuated low frequency is less than or equal to the low frequency region of the human audio spectrum; embedding, by the one or more processors, the set of data representing the QR Code into data representing a tone in the low frequency; inserting, by the one or more processors, into the audio data of the third file, the data representing the tone in the low frequency embedded with the set of data representing the QR Code; and broadcasting, by the one or more processors via a speaker, the audio data of the third file, wherein the audio data is received by a device which extracts the set of data representing the QR Code from the low frequency of the audio data of the third file.
