Ikchha Pandey | Siddarth Bhalerao | Papiya Dutta "Comparative Studies of various Digital Image & Audio Watermarking Techniques" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-3, April 2018, pp.2278-2284, URL: https://www.ijtsrd.com/papers/ijtsrd12700.pdf

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 & 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.
