transferring the data or messages from one end to the other end. The main objective of the paper is to hide the message or a secret data into an image which acts as a carrier file having secret data and to transmit to the intention securely. The watermark can be extracted with minimum error. In terms of PSNR, the visual quality of the watermarked image is exceptional. The proposed algorithm is robust to many image attacks and suitable for copyright protection applications. KEYWORDS: Watermarking

watermarking is used for providing a kind of security for various type of data (it may be image, audio, video, etc). Digital watermarking generally falls into the visible watermarking technology and hidden watermarking technology visible and invisible watermarks both serve to deter theft but they do so in very different ways. Watermarking is identified as a major technology

Sophisticated watermark embedding is a potential method to discourage unauthorized copying or attest the origin of the images.One approach used to address this problem is to add a visible or invisible structure to an image that can be used to seal or mark it. These structures are known as digital watermarks. Digital watermark is a kind of technology that embeds copyright information into multimedia data. Each watermark method consists of an embedding algorithm and

SMUGGLING VOIP WATERMARKS USING INTENDED CORRUPTED PACKETS Mazen Mohamed Flaifl, Ismail Abdel Ghafar Ismail, Mohamed Zaki and Ashraf Diaa El- Deen Bayomi Department of Computer Engineering Military Technical Collage ABSTRACT Designing and embedding a watermark for VoIP is the main goal of this paper, A new model is introduced and characterized by high robustness, high security and must be non-perceptual. The watermarking model is suitable for real-time service and supports the needs of embedding

spatial domain based on Inter Block Pixel Difference (IBPD). The cover image is divided into 8×8 non overlapping blocks and difference between intensities of two pixels of adjacent blocks at predefined positions is calculated. Depending upon the watermark bit to be embedded; both the pixels are modified to bring the

blaster pro+ can be used to produce numerous specific films. Also you can create a video that can play for 10 minutes in less than two minutes. This two minutes is inclusive of picture and sound downloads, addition of textual content together with watermarks in the video. The voices of more than 50 men and women are included in this software and over 10 languages. The most important thing is that there is no restriction of the number of slides you will make. This is the latest update from the previous

video, audio, and text has long been a concern for owners of these digital assets. Protection schemes are usually based upon the insertion of digital watermarks into the data. The watermarking software introduces small errors into the object being watermarked. These intentional errors are called marks, and all the marks together constitute the watermark. The marks are chosen so as to have an insignificant impact on the usefulness of the data and are placed in such a way that a malicious user cannot

Research in the field of watermarking is flourishing providing techniques to protect copyright of intellectual property. Among the various methods that exploits the characteristics of the Human Visual System (HVS) for more secure and effective data hiding, wavelet based watermarking techniques shows to be immune to attacks, adding the quality of robustness to protect the hidden message of third party modifications. In this paper, we introduced non blind with DWT & SVD . Also we applies a casting

• Capacity: The amount of information that can be discerned by the user. The challenges are to introduce a digital watermark that is both transparent and highly robust to common signal processing and possible attacks. The two basic requirements for an effective watermarking scheme robustness and transparency conflict each other. An effective watermarking scheme is achieved
