Copyright protection using blind video watermarking algorithm based on MPEG-2 structure

Abstract

Video watermarking plays a key role in copyright protection domain of today's world. In the following paper, a blind watermarking algorithm is being proposed in which the watermark information is being embedded by little alteration of some of the value of DCT coefficients of luminance part of video during encoding it in MPEG-2 style. It is obvious that for any type of watermarking the three parameters, robustness, perceptibility and payload capacity must be simulated in order to provide better results . But unfortunately there is always a trade off among all these three parameters. But the proposed algorithm focused on one more issue, 'elapsed time', a serious concern in video watermarking. The special care must be taken that how much time the system takes to embed the watermark. The algorithm is being tested also against several intentional and unintentional attacks to judge the robustness of this scheme. To maintain the perceptibility issue the value of threshold is manage in such a way that the quality of video must not being compromised during the embedding process. Therefore, the superiority of this algorithm is that our approach has covered three characteristics and evaluated better results as compared to the existing techniques proposed by other researchers.

Compressed domain based robust digital video watermarking scheme to protect the copyright

“…Little enhancing the controlfeature, extremely degrade the quaity of watermarked video. Ahuja et al [16] stretched the work by exploiting the MPEG2 structure to cover the above limitations. They also focused on efficiency of the watermark scheme by calculating the elapsed time.…”

Automatic Rotation Recovery Algorithm for Accurate Digital Image and Video Watermarks Extraction

“…Some examples of low resistance to rotation attacks are obviously reported in [8,9,10,11,12,13,14]. In these works the watermark after rotation attack was difficult to be accurately extracted and the data was mostly lost.…”

Authenticate audio video-crypto invisible watermarking approach for enhancing hidden information security and robustness

“…Ahuja et al have focused on a video watermarking scheme using a MPEG-2 coding style which used for the application of copyright protection and it applied various attacks on watermarked video and measured parameters like robustness, perceptibility, EC along with one more issue 'elapsed time', a serious concern in video watermarking. For testing the performance of a video watermarking algorithm and also suggested to apply more video processing attacks like frame insertion, frame deletion, frame averaging and compression attacks (Ahuja and Bedi, 2015). Su et al have introduced the new blind watermark algorithm which embedded the binary watermark image into the blue component of an RGB image in the spatial domain to resolve the problem of protecting copyright.…”
