| Abstract: |
This work presents a robust audio data hiding system based on the direct sequence spread spectrum technique. The algorithm presented inserts watermarks in random frequencies in the audio input, making it imperceptible to the human auditory system. The results indicated the efficiency of the system regarding the payload and data transparency.
