Abstract
It proposes an approach for audio watermarking using the singular value decomposition (SVD) mathematical technique. After transforming it into a 2-D format the encrypted image is embedded in the singular values of the audio signal. After watermark embedding, the audio signal is transformed again into a 1-D format. For encrypt the image chaotic encryption is used. It improves the quality of extracted images as proved experimentally, where it resists the noise and different attacks.
