Data Over Sound: Encryption is Key

You can send data over audio and it just might be more secure than using RF.
Using acoustic networking to transfer data provides some unique benefits for a vast number of applications in a wide array of industries. Applications range from delivering a simple and low-cost entry system for public transport to facilitating peer-to-peer (P2P) payments between two connected parties. The fundamental properties of sound can work to enable a seamless exchange of data payloads across a range of physical environments.
While the usability and time-saving capabilities of data-over-sound are well-understood, there remains a question from those assessing the viability of implementing this type of data transmission into their operations: Can information being transmitted over sound be protected from nearby eavesdroppers? On one hand, audio seems to be more secure than IP-based connectivity, which hackers can remotely penetrate. To put the question to bed, let’s look at the characteristics of sound and how industry-standard encryption can be applied to acoustic data transfer, rendering it secure and safe from the ears of unwanted listeners (Figure 1).
