Persistence of Shadow Education issues of copyright protection and authentication that are appropriate for this standard become very important. In this paper, a blind video watermarking algorithm for H.264/AVC is proposed. The watermark information is embedded directly into H.264/AVC video at the encoder by modifying the quantize

Previously, we proposed to reinforce its security by using a secret space before the embedding. This secret space requires to compute projections onto secrets carriers. When dealing with

However, this scheme is designed with spatial filtering in mind, this is the dot-size variant part of the scheme. Dot-size variant means that instead of having single black and white

In this method, noise type pixels are selected for pixel-wise data embedding using a secret key. The data hiding process through pixel flipping introduces some background noise in watermarked images and could pres

In particular, the proposed method considers the distribution of the number of zeroes and ones in the input message, as well as how the message bits are distributed over the colors in the image palette.
