Yatish Y. Jani, Yagnesh J. Parmar, Chintan J. Kavathiya . A Review on New Technique for Embedding Image into Audio as a Watermark using DCT. International Journal of Computer Applications. 88, 9 ( February 2014), 19-22. DOI=10.5120/15381-3812
Abstract
Globalization and internet are the two main reasons for rapidly spreading of the multimedia information and due to that ownership and copyright of multimedia files are not usually protected by the providers. Digital watermarking is one of the best ways for copyright protection. Researchers are trying to invent new techniques that increase the security, Robustness and many more things. In this paper we proposed a new technique based on DCT. In this technique bits used as a watermark are inserted in whole audio file. Watermarked bits are inserted in all frames' first bit in such a way that it should not affect the original media file. This method is comparatively easy to implement, more robust and can carry more data as a watermark.
