O knihe
Steganography is the art and science of secret hiding. The secret message or plain text may be hidden in various ways. The methods of cryptography render the message unintelligible to the outsider by various transformations of the text whereas the methods of steganography conceal the existence of the message. To conceal a secret message we need a wrapper or container as a host file. Different wrappers or host files or cover medium are used to hide the secret message e.g. image, audio, video, text. The work in this paper aims at enhancing the provision of audio steganography by introducing one LSB (Least Significant Bit) Coding technique. We design a high bit rate LSB audio watermarking method that reduces embedding distortion of the host audio with increased capacity of secret text. By using standard and proposed algorithm, watermark bits are embedded into higher LSB layer, resulting in increased robustness against noise addition, which is limited by perceptual transparency. There are three types of domains & various techniques of audio steganography are present in each domain. They all are having the different embedding methods.
