The digital audio watermarking scheme based on Tetrolet wavelet transforms to extract a watermark in image by hiding the audio in image. To determine the sub-image in the host image the essential features lies in it. In the most significant region of the host image, the invisible insertion of the audio in the image after watermarking, the tampering of that image is destroyed and degrades the original quality of the image. Tetrolet transform is used to build the efficient watermarking method and used for the extraction it connects the four identical squares called as tetrominoes and each of them it is attached over the least one square in the boundary of the image. In this method, the Tetrolet transform used as a transmitter to extract the image.
