With the development of the Internet coupled with expanding the accessibility of multimedia, various copyright issues have resulted. Several researchers have been working on watermarks to provide the security, durability, and a perception of multimedia. This paper a review of some recent works is presented related to video watermarking techniques, this study focuses on the pros and cons of recent video watermarking, areas of application, and the different types and attacks that are standing against these watermarking techniques. The results obtained from this study showed that watermark techniques based on the transfer domain, are more popular than those of the spatial domain.

Text Hiding in 3D Object

In this research was to propose a new way to hide data from the text in the tri-dimensional images type depending on the geometric style is proposed, this can be done via the manipulation of the location of the (vertex) in most areas of softness in the triangular object dimensions of any of the many details areas so we make sure not to detect the presence of the data eye human. The experimental results showed, a high rate of failure note the presence of hidden data depending on the scale "RMS" Tripartite-dimensional images, and the way showed good resistance to the types of geometric attack such as "translation"," rotation" and "scaling" and out where he was retrieving a full hidden data without any destruction and this is what boosted "BER".

Random Insertion Watermarking By Computing Angle Between Two Lines In Blue Components On Postage Stamp

This paper presents a new approach for watermarking by using geometric analytic
and mathematical model providing robustness to embed the watermarking in postage
stamp (ps) image, using the angle between two lines to insert the embedded
information in blue component for pixels. Analytic geometry, also known as
coordinate geometry, or Cartesian geometry, is the study of geometry using a
coordinate system and analysis. The modern and advanced meaning refers to the
geometry of analytic varieties, to develop a data-hiding method that has a good
performance in color images. Furthermore, the watermark must be either robust or
fragile; depending on the application. The expression "robust" in this paper refers to
the capability of the watermark to resist manipulations of the media. Two types of
watermarked attack was used; the JEPQ compression as lossy compression (where
compressing and decompressing data retrieve hidden information that may be close
enough to the original image), and the enhancement filter (mean filter). This proposed
watermarking system refers to the watermark objective evaluation test or (WOET).
