LSB Algorithm to Hide Text in an Audio Signal

Bárbara Emma Sánchez Rinza, L. Gerardo Munive Morales, Alberto Jaramillo Núñez


The following work is to hide a text in an audio file using steganography employing the LSB algorithm. 3 melodies of different genres are used to see by which of the 3, the information is best hidden, without there being any noise in the melody that will contain the hidden message. This is quite important in steganography because it is required that information goes unnoticed. To do so, we programmed in Matlab, and in this case, our hidden message contains around 9429 characters.
