The basic spread spectrum (SS) method attempts to spread secret information across the frequency spectrum of the audio signal. This system is similar to a system which uses an implementation of the LSB that spreads the message bits randomly over the entire sound file. Unlike LSB coding, the Spread Spectrum method spreads the secret information over the …

LEAST SIGNIFICANT BIT Least significant bit (LSB) coding is the simplest way to embed information in a digital audio file. By substituting the least significant bit of each sampling point with a binary message. In implementations of LSB coding, the least significant bits of a sample are replaced with message bits. To extract a secret message from an LSB encoded …

The LSB algorithm The most common and popular method of modern day steganography is to make use of LSB of picture’s pixel information. This technique works best when the file is longer than the message file and if image is grayscale. When applying LSB techniques to each byte of a 24 bit image,three bits can be encoded into each pixel.

Audio Steganography Embedding secret messages into digital sound is known as audio Steganography. Audio Steganography methods can embed messages in WAV, AU, and even MP3 sound files. The properties of the human auditory system (HAS) are exploited in the process of audio Steganography 26. Audio Steganography To embed data secretly onto digital …

11. Steganalysis is the art and science of detecting a secret communication. Hiding a message will most likely leave detectable traces in the cover medium. The information hiding process changes the statistical properties of the cover, which is a steganalyst attempts to detect. The process of attempting to detect statistical traces is called ...
Steganography in Images Using LSB Technique

steganography algorithm is LSB embedding algorithm. b. Audio Steganography: Steganography can be applied to audio files i.e., we can hide information in an audio file, it can be called Audio Steganography. The audio file should be undetectable. c. Video Steganography: Steganography can be applied to video files also. If we hide information in a video
A Perusal Study of Audio Steganography with LSB Techniques

A very interesting audio steganography method is the LSB (Least Significant Bit) algorithm. The least significant bit of the cover media is playing as a mask to the secret message. The modification made in such a way to the LSB bit should not be understood in the final stego object. Being an easy technique, a high level of security is
