Video Watermarking using Interlacing Approach for Copyright Protection

Recent developments in wireless communication, the transmission of digital contents are more. With respect to the distribution of multimedia contents, hackers have the enthusiasm to read, copy and adjust the computerized information effortlessly. This book presents a video watermarking using interlacing approach is concerned with enhancement of security and robustness. A luminance layer of frames is shared into two even and odd rows of an image. This process is called interlacing, furthermore, it is deinterlacing by removing the zero rows and equalizing the two shares. Now the watermark is concealed in any one of the shares under wavelet transform. Hence, the watermark information is requested with satisfying by the human visual system which makes them undetectable. The test results demonstrate that watermark is efficient in content protection, which is near with the quality of standards that need for the multimedia applications. Moreover, further possible directions for developments of these techniques are outlined.
