What is phase coding in audio steganography?
In phase encoding scheme the phase of carrier file is replaced with reference phase which represents hidden data. In parity coding signals are divided into regions, then parity bit of each region calculated and matched with secret message bit. Depending on parity matching result encoding is done.
Which algorithm is used in audio steganography?
A famous audio steganography approach is the LSB (Least Significant Bit) algorithm. In this, the least significant bit of the cover signal can be used to hide the message. This is a very simple method. The changes create to the LSB bit will not be reflected in the last stego signal.
How is steganography used with audio files?
Audio Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. It is the science of hiding some secret text or audio information in a host message. The host message before steganography and stego message after steganography have the same characteristics.
What is audio Steganalysis?
Abstract. Audio steganography is about hiding the secret message into the audio. It is a technique uses to secure the transmission of secret information or hide their existence. It also may provide confidentiality to secret message if the message is encrypted.
