AN EFFICIENT VIDEO WATERMARKING SCHEME FOR CONCEALING DATA RECORDS USING LABVIEW
Publication Date : 10/04/2016
This paper proposes a watermarking algorithm for hiding the data securely over the public network. A watermark is embedded into YCBCR (Y-Luminance, CB-Chrominance Blue, and CR-Chrominance Red) colour channels of each video frame using Discrete Wavelet Transform with Principle Component Analysis. The process of digital watermarking involves the modification of the original multimedia data to embed a watermark containing a key information such as authentication copyright codes. The embedding method must leaving the original data perceptually unchanged, yet should expose modification which can be detected by using an appropriate extraction algorithm. This method is implemented using LabVIEW. Keywords: Video Watermarking, Defence Data Records, Principle Component Analysis, DWT.
