Design and Development of Video Watermarking System using Wavelet Transform

Abstract

Due to rapid growth of internet users of networks, owners of the digital products are concerned about illegal copying of their products. Security and copyright protection are becoming very important issues in today’s multimedia applications and services. Digital watermarking is a technology used for copyright security; here ownership information data which is called watermark is embedded into the digital media without affecting its perceptual quality. In case of any difference of opinion, the watermark data can be detected or extracted from the media and use as a proof of ownership. Nowadays, due to the rapid advances in the field of Information Technology digital data can be easily created, copied, processed and can be distributed freely among unauthorized users , and for that, copyright laws are not adequate to deal with digital data. Watermarking can be used to protect the genuineness and authenticity of the owner. In this, video watermarking with text data by using the Quick Response (QR) code technique is used. In this paper, we are going to use Discrete Wavelet Transform (DWT) technique for video watermarking.
