Embodiment Construction

[0016] overview

[0017] Examples described herein provide computer-implemented techniques for dynamic audio-based data transmission masking. By using and relying on the methods and systems described herein, broadcast computing devices and account management computing systems provide the ability to communicate data via audio communication channels in a manner that is more pleasing to the human ear. As such, the systems and methods described herein enable data to be communicated by a broadcast computing device via an audio communication channel, wherein a second sound is generated to mask the objectionable nature of the communicated data.

[0018] In an example, the account management computing system generates a set of rules that can be applied by the broadcast computing device to create ideal masking sounds. In an example, the set of rules includes a function or algorithm that, when applied to known data points from the encoded sound, produces an ideal masking sound. In thi...

Abstract

Techniques herein provide computer-implemented methods to dynamically mask audio-based data transfer. A computing device encodes data to be transferred into an audio file that produces a sound unpleasant to the human ear. The computing device determines frequency points and amplitude for the encoded audio file, and creates a masking sound file based on the determined frequency points and amplitude. The masking sound file may comprise a masking sound that is pleasant to the human ear. The computing device plays the encoded audio file and the masking sound file. In an example, the computing device combines the encoded audio file and the masking sound file into a single sound file and plays single sound file. In another example, the computing device plays the encoded audio file and the masking sound file as two separate sound files simultaneously.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to U.S. Patent Application Serial No. 62 / 546,133, filed August 16, 2017, entitled "Dynamic Audio Data TransferMasking." The entire contents of the above application are hereby fully incorporated by reference. technical field [0003] The techniques disclosed herein involve dynamic creation of optimal audio output to mask audio-based data during transmission. Background technique [0004] Mobile computing devices typically exchange data via the Internet. Where an Internet connection is not available or desired, a peer-to-peer connection, such as Bluetooth or near field communication, can be used to transfer data. However, these peer-to-peer solutions require specific hardware and APIs to function. Accordingly, there is a need to enable and use features and hardware typically found on mobile computing devices to exchange data. [0005] By definition, every telephone or mobile c...
