Comparative Studies of various Digital Image and Audio Watermarking Techniques

In this paper a brief review of various audio and image watermarking techniques has been carried out. Properties of both image and audio are different while processing. In this work a blind frequency masking algorithm for hiding the image data into audio signal using DCT is proposed. DCT provides compression and to avoid distortions from DCT compression, additional password key would be used to encrypt data in frequency domain. The secret key or a password would be required to extract a data, also helps to make the data immune from noise effects represented by the addition the host signal in the embedder. In a blind watermark detector, the un watermarked host signal is unknown, and cannot be removed before a watermark extraction. Under these conditions.
