In this paper, a wavelet based watermarking scheme for the protection of document and graphics images is proposed. Document and graphics images are different from other images as such images are typically in two colors only (generally white as background and black or other color as text or drawing). In document or graphics images, white background area is usually more than the text or drawing c...

Content authentication, integrity verification, and tampering detection of digital content exchanged via the internet have been used to address a major concern in information communication technology. In this paper, text zero-watermarking approach known as Smart-Fragile Approach based on Soft Computing Digital Watermarking (SFASCDW) is proposed for authentication English text. A first-level ord...

Multimedia watermarking technology has evolved very quickly during the last few years. A digital watermark is information that is imperceptibly and robustly embedded in the host data such that it cannot be removed. A watermark typically contains information about the origin, status, or recipient of the host data. In this tutorial paper, the requirements and applications for watermarking are rev...

The ease of reproduction, distribution, and manipulation of digital documents creates problems for authorized parties that wish to prevent illegal use of such document. To this end, digital watermarking has been proposed as a last line of defense. A digital watermark is an imperceptible, robust, secure message embedded directly into a document. The watermark is imperceptible both perceptually a...

Cloud computing in today’s world is making wide differences between it and other technologies. The critical data of users can be stolen by various means whereas cloud computing is still not a secure way to store users data. This paper tries provides a review of what are various types of digital watermarking techniques and in what way the integrity of watermarking can be attacked so as throttle ...

This study focuses on Arabic text watermarking semi-verification utilizing recent counting-based secret-sharing to partially validate the ownership and correctness for all sensitive medical e-records. The benefit of this approach is its semi-trust e-records, as needed services provided, even if complete report a bit delayed full verification. Proposed work presents two approaches text-watermark...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In recent year, to protect digital content (text, images, audio, and video) from illegal manipulations that has been developed digital image watermarking techniques. In this paper we proposed two different watermarking schemes based on DCTDWT-SVD. ...

Digital watermarking is a very recent research area. Digital audio watermarking is a method to embed or hide the Watermark (Information signal) into a digital signal i.e. Image, audio, text or video data. The watermark is difficult to remove from the audio signal. If the signal is copied, the information or watermark is also carried in the copy. A signal may carry several different watermarks a...

In recent years, internet revolution resulted in an explosive growth in multimedia applications. The rapid advancement of internet has made it easier to send the data/image accurate and faster to the destination. Besides this, it is easier to modify and misuse the valuable information through hacking at the same time. Digital watermarking is one of the proposed solutions for copyright protectio...

With the rapid growth of network multimedia systems and other numerical technologies, images, audio, text and video can be more easily produced, processed as well as stored by digital devices in recent years. To conceal data in transmitting message for copyright protection the secret is very important. Various Digital Watermarking Techniques are developed to protect the secret data. This paper ...
