Illegal distribution of digital data is a common danger in the film industry, especially with the rapid spread of the Internet, where it is now possible to easily distribute pirated copies of digital video on a global scale. The Watermarking system inserts invisible signs to the video content without changing the content itself. The aim of this paper is to build an invisible video watermarking system with high imperceptibility. Firstly, the watermark is confused by using the Arnold transform and then dividing into equal, non-overlapping blocks. Each block is then embedded in a specific frame using the Discrete Wavelet Transform (DWT), where the HL band is used for this purpose. Regarding the method of selecting the host frames, the chaotic map (tent map) was used to choose a number of frames which are greater or equal to the number of blocks of the watermark. The host frame selection method makes the discovery of the watermark information by illegal means very complicated. The experimental results show that the proposed method can produce excellent transparency with robustness against some attacks where the average_ PSNR reaches to 72.806.

The interchange of information over the internet and networks has grown fast. The Digital images occupy an important role in multimedia communications. Images are utilized in a variety of discipline, including biometric authentication, military, medical science; hence, their security become a major concern. The best solution for securing the data (in any form) is encryption. The recent encryption trend is chaos-based encryption. Image encryption approaches based on chaos have essential merits l. This paper surveys various aspects and approaches of chaos maps image encryption like PWLCM (piecewise linear chaotic map), logistic map, skew tent map. Considering security measurements like correlation analysis and keyspace when comparing image encryption techniques that use different chaotic maps.

“…The chaotic systems have been previously considered in the context of data encryption [5][6][7][8] and secure information transmission [9][10][11]. They are characterized by their rich and complex dynamical behavior due to their sensitive dependency on initial conditions and parameter changes, despite their intrinsically simple and deterministic structures [12].…”

A network of chaotic systems can be designed in such a way that the cluster patterns formed by synchronous nodes can be controlled through the coupling parameters. We present a novel approach to exploit such a network for covert communication purposes, where controlled clusters encode the symbols spatio-temporally. The cluster synchronization network is divided into two subnetworks as transmitter and receiver. First, we specifically design the network whose controlled parameters reside in the transmitter. Second, we ensure that the nodes of the links connecting the transmitter and receiver are not in the same clusters for all the control parameters. The former condition ensures that the control parameters changed at the transmitter change the whole clustering scheme. The second condition enforces the transmitted signals are always continuous and chaotic. Hence, the transmitted signals are not modulated by the information directly, but distributed over the links connecting the subnetworks. The information cannot be deciphered by eavesdropping on the channel links without knowing the network topology. The performance has been assessed by extensive simulations of bit error rates under noisy channel conditions.
