A Compressed-Domain Robust Video Watermarking Against Recompression Attack

Compressed Domain Robust Video Watermarking

Recently, video watermarking has become an important research issue due to increase in threats of video piracy, authentication, and ownership integrity. In this paper, we propose a new secure and robust watermarking method for H.264 compressed video stream with a blind extraction process. Most authors prefer embedding in I-frames because I-frames are crucial for video signal. However, the embed...

Secure and Robust Compressed-Domain Video Watermarking for H.264

Robust multiplicative video watermarking using statistical modeling

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

Robust Mpeg Video Watermarking in Wavelet Domain

A semi-blind image watermarking scheme embeds a pseudo random sequence in all the high pass DWT coefficients above a given threshold T1. The attacked DWT coefficients are then correlated with the original watermark. For watermark detection, all the coefficients higher than another threshold T2 (>T1) are chosen for correlation with the original watermark. This idea was extended to embed the same...

A Practical Real-Time Video Watermarking Scheme Robust against Downscaling Attack

In this paper, we propose a practical real-time video watermarking scheme for downscaling attack. We embed watermark into an arbitrary size of a host video and extract it from the watermarked video under a preset false error rate. Both watermark embedding and extraction are done in the uncompressed domain. Also, blind detector is used (i.e., no original video needs during the detection). As our...
