From Last few year, internet became the first priority of everyone. It is a very easy and fast way to transfer and access data and information throughout the world. This information basically in the form of digital data (text, images, audio, video). Everyone using internet for their personal or professional use. Due to this it is important to protect user data from unauthorized access. When we ...

This paper describes a new image watermarking technique based on the Natural Preserving Transform (NPT). The proposed watermarking scheme uses NPT to encode a gray scale watermarking logo image or text, into a host image at any location. NPT brings a unique feature which is uniformly distributing the logo across the host image in an imperceptible manner. The contribution of this paper lies is p...

The most common digital media exchanged via the Internet is in text form. Arabic language considered one of sensitive languages content modification due to presence diacritics that can cause a change meaning. In this paper, an intelligent scheme proposed for improving reliability and security Internet. core mechanism depends on integrating hidden Markov model zero watermarking techniques. water...

Sustaining copyright protection in multimedia contents like text, images, audio and video become a challenging issue in today’s environment. Digital watermarking enables us to hide secret information within the original contents itself. In this paper, the concern is with video contents in which watermarking have become a necessity due to piracy, copying etc. The main focus in this paper is on p...

Insertion of a text message, audio data or/and an image into another image or 3D model is called as a watermarking process. Watermarking has variety of applications like: Copyright Protection, Owner Identification, Copy Protection and Data Hiding etc., depending upon the type of watermark insertion algorithm. Watermark remains in the content after applying various attacks without any distortion...

Much research and development have been made to implement deep neural networks for various purposes with hardware. We the learning algorithm a dedicated processor. Watermarking technology ultra-high resolution digital images videos needs be implemented in hardware real-time or high-speed operation. propose an optimization methodology learning-based watermarking The proposed includes memory opti...

In Digital era sharing of images have become very common and raises the risk of using it for unethical and fraudulent purposes with the help of manipulation tools. Digital image watermarking is one way to protect the digital information (text, images, audio, and video) from fraudulent manipulations. Digital Image Watermarking is a process of implanting data in the original image for authenticat...

This paper proposes a novel watermarking algorithm for grayscale text document images. The algorithm inserts the watermark signals through edge direction histograms. The concept of sub-image consistency is developed. The concept means the sub-images have similar-shaped edge direction histograms and it is shown to be valid over a wide range of document images. Algorithms to insert and detect wat...

It is becoming easier and easier to tamper with digital Works in ways that are difficult to detect. The problem of authentication has been well studied. This paper proposes a novel erasable text watermarking scheme for exact authentication, which including authentication of content and format of Chinese Word documents. In this method, the cover document is divided into two blocks by utilizing t...

Natural language generation (NLG) models combined with increasingly mature and powerful deep learning techniques have been widely used in recent years. Deployed NLG practical applications may be stolen or illegally, watermarking has become an important tool to protect the Intellectual Property (IP) of these models. Watermarking technique designs algorithms embed watermark information extracts f...
