Online content distribution businesses require methods to protect the intellectual property of distributed content. Intellectual property protection is a mechanism to protect the rights of ownership of original work so that no one can use the rights-protected work in any way without seeking permission for the use and, if necessary, paying the rights owners a royalty for the use. Digital waterma...

In today’s digital world securing different forms of content is very important in terms of protecting copyright and verifying authenticity. One example is watermarking of digital audio and images. We believe that a marking scheme analogous to digital watermarking but for documents is very important. In this paper we describe the use of laser amplitude modulation in electrophotographic printers ...

The growth of the Internet has frequently increased the availability of digital data such as text, audio, images and videos to the public. Digital watermarking is one of the important techniques to secure digital data in the field of authentication, copyright protection and security. The non-blind watermarking systems have a main problem that for extracting the watermark image from the watermar...

Received Nov 09, 2015 Revised Mar 14, 2016 Accepted Mar 20, 2016 Transform-domain digital audio watermarking has a performance advantage over time-domain watermarking by virtue of the fact that frequency transforms offer better exploitation of the human auditory system (HAS). In this research paper an adaptive audio watermarking is proposed based on the low and high wavelet frequencies band (LF...

This paper addresses the problems and threats associated with verification of integrity, proof of authenticity, tamper detection, and copyright protection for digital-text content. Such issues were largely addressed in the literature for images, audio, and video, with only a few papers addressing the challenge of sensitive plain-text media under known constraints. Specifically, with text as the...
