Abstract
Methods and systems for high frequency injection and detection for improved false acceptance reduction are disclosed. An information handling system may be configured to receive audio data and to add an identification signal to the audio data, wherein the identification signal is determined based on the audio data. The combined audio data and the identification signal may be output to a receiving device. An information handling system may also be configured to receive data that includes audio data and an identification signal that is associated with one or more frequencies in the audio data, identify the one or more frequencies in the audio data that are associated with the identification signal, and attenuate the one or more frequencies in the audio data to obtain modified audio data. The modified audio data may be output for audio processing.
