What is LSB?
The term “LSB” refers to the Least Significant Bit, a fundamental concept in binary representation. In binary code, each digit, or bit, holds a specific place value based on its position within a sequence. The Least Significant Bit is the rightmost bit, representing the smallest numerical value. In a byte (8 bits), the LSB is the final bit, carrying the least weight in numerical terms.

LSB in Digital Steganography
Beyond its role in binary representation, LSB plays a crucial role in digital steganography, the art of concealing information within other data to ensure its covert transmission. In this context, LSB manipulation involves altering the least significant bit of pixel values in an image or the least significant byte in audio files without significantly impacting the overall data.

LSB in Images
In image steganography, LSB manipulation allows for the hiding of secret messages within the pixel values of an image. By subtly modifying the least significant bit of each pixel, practitioners can embed information without visibly altering the image’s appearance. This technique capitalizes on the fact that small changes to the LSB have minimal impact on the image’s visual quality.

Audio Steganography and LSB
Similarly, LSB finds application in audio steganography, where it aids in concealing information within the least significant bytes of audio samples. By strategically altering these bits, practitioners can embed messages or data in audio files without causing noticeable distortion to the human ear.
