In this paper, using a new two-dimensional complex map, a secure video watermarking
system is presented. Standard analyzes have been performed to analyze a dynamical …

In the modern world, high-bandwidth internet access has led to the theft of all types of digital
data, including digital video, and their illegal distribution. The digital video watermarking …

Currently we are facing a wide interest in multimedia security and copyright protection due to
the explosion of data exchange in the Internet and the extensive use of digital media. In this …

The rapid growth of fast communication networks for digital video transmission has created a
need to copyright protection for these media. Digital video can be manipulated easily by …

Watermarking is a widely used solution to the problems of authentication and copyright
protection of digital media especially for images, videos, and audio data. Chaos is one of the …

This paper presents the new digital watermarking algorithm based on the chaotic map. Data
can easily be hidden in images by using the least significant bits. In the anticipated …

The advancement of Internet technologies has led to the availability of audios, images, and
videos in different forms. The unauthorized users are exploiting the use of multimedia by …

Watermarking techniques have been developed to protect digital images against illegal
reproductions and illegal modifications. In this paper, a non-blind digital image …

This paper presents a public video watermarking algorithm, whose robustness depends on
the embedding energy, which must be limited due to the degradation of video sequence …

In this paper, we propose a robust block classification based semi-blind video watermarking
algorithm using visual cryptography and SURF (Speed-Up Robust Features) features to …
