Image watermarking is an important aspect of the security of data. The robustness of watermarking and the capacity of the watermarking process are the main research area for researcher. The watermarking including encryption technique is the main aim of this paper. Discrete Wavelet Transform has been used for the watermarking and PN sequence based random sequence is used for the encryption of th...

Digital Image Watermarking is the procedure of embedding message/information/logo into a digital image which may be used to verify its accuracy or the uniqueness of its user. The data is also passed in copy, if the image watermarked is to be copied. Too many Image watermarking methods have to be proposed in digital watermarking. We have study a variety of methods in this paper, the way to expre...

Watermarking is a technique, which is used in protecting digital information like image, video and audio as it provides copyrights and ownership Audio watermarking is more difficult than image watermarking than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. Digital watermarking is a technique by which copyright information is embedded into the host si...

Medical image security is possible using digital watermarking techniques. Important information included in a host medical order to provide integrity, consistency, and authentication the healthcare system. This paper introduces proposed method for embedding invisible 3D image. The cover used DICOM which consists of number slices, each one representing sense, firstly must separate ROI (Region In...

Digital image watermarking have been developed widely in recent years. One of the most important applications of digital image watermarking is medical applications. Image watermarking can be used in medical images for several purposes. It’s used to protect the patient’s information from unauthorized people. In addition, it can be used for authentication if the patient lost his/her image. Moreov...

This paper proposes a new approach for enhancing the robustness of wavelet-based image watermarking algorithms. The method adjusts wavelet used in the process of image watermarking in order to maximize resistance against image processing operations. Effectiveness of the approach is demonstrated using blind multiplicative watermarking algorithm, but it can easily be generalized to all wavelet-ba...

On the basis of the research of wavelet transform and digital watermarking technology, this paper proposed a self-adaptive discrete wavelet transform (DWT) digital watermarking algorithm, which can achieve the purpose of embedding hidden watermarks by decompose three-level wavelet of image and decompose bit-plane of watermarking gray scale image by Arnold scrambling transformation. Layer adapti...

The growth of computer networks has boosted the growth of the information technology sector to a greater extent. There is a trend to move from conventional libraries to digital libraries. Embedding a digital signal with information which cannot be removed easily is called ‘Digital Watermarking’. Visible watermarking is a type of digital watermarking used for protection of publicly available ima...

-With the increasing influence of digital network and communication, armour from perilous intrusion and corruption of information (e.g. image, video, speech etc) during transmission is a paramount issue. To protect the image and video from the unauthenticated access or tampering, watermarking is adopted as a solution. In this paper we have proposed a spatial domain Spread Spectrum (SS) watermar...

With the growing interest in copyright protection of multimedia, digital watermarking has been presented and widely researched. The digital image watermarking techniques are usually performed in spatial or transform domain. Most of transformdomain watermarking methods are based on Discrete Cosine Transforms (DCT) and robust to JPEG lossy compression. Recently, digital image watermarking based o...
