Embedding a hidden stream of bits in a file is called Digital Watermarking. The file could be
an image, audio, video or text. Nowadays, digital watermarking has many applications such
as broadcast monitoring, owner identification, proof of ownership, transaction tracking,
content authentication, copy control, device control, and file reconstruction (Cox et. al., 2008).
In literature, the host file is called the asset , and the bit stream is called the message . The
main specifications of a watermarking system are: Robustness (Against i ....etc

Abstract
Digital watermarking technique emerged as a tool for protecting the multimedia data from copyright infringement. In digital watermarking an imperceptible signal is embedded into the host image, which uniquely identifies the ownership. In the proposed algorithms, DNA sequence is used as a digital watermark, as the DNA sequences are unique and difficult to copy. This paper proposes two algorithms namely content based watermark algorithm using DNA sequence (CBDNA) and user specified watermark algorithm using D ....etc

The possibility of adding several watermarks to the same image would enable many interesting applications such as multimedia document tracing, data usage monitoring, and multiple property management. In this paper, we present a novel watermarking scheme, which allows inserting and reliably detecting multiple watermarks sequentially embedded into a digital image. The proposed method, based on elementary linear algebra, is asymmetric, secure under projection attack and robust against distortion due to basic operations such as storage, transmissio ....etc

Abstract
Digital watermarking is the process of possibly irreversibly embedding information into a digital signal. The signal may be audio, pictures or video, for example. If the signal is copied, then the information is also carried in the copy,An important application of invisible watermarking is to copyright protection systems, which are intended to prevent or deter unauthorized copying of digital media

In this proposed algorithm, according to the size of the image we have to multiply the hadamard coefficient(Hn).In fut ....etc
