A Method for Embedding Information Into Acceleration Data Using Resonant Frequency Sound to Capacitive Accelerometers

This chapter explores a groundbreaking method for embedding information into acceleration data using resonant frequency sound. The study begins by discussing an attack that manipulates capacitive accelerometers through sound irradiation. The proposed method involves creating sound data from binary information, irradiating the accelerometer with specific sound patterns, and extracting the embedded bit sequences. Preliminary experiments determined optimal sound frequencies, pressures, and durations for different types of accelerometers. The method's effectiveness was evaluated in both stationary and dynamic scenarios, demonstrating high accuracy in extracting information from multifunctional sensors and smartphones. The chapter concludes with a summary of the method's capabilities and potential applications in various contexts.
