The universal storage and transmission of information by text-based documents makes information hiding technology an important topic in computer security. Currently, the popularly used text-based information techniques are facing many problems, such as poor robustness, low embedding rate, semantic clutter and can be easily distinguished by unaided eyes. In order to solve these problems, this pa...

Data hiding techniques are getting very large support from research community during the last two decades. Steganography is the widely used technique during the last few years for data hiding. Steganography is the art and science of hiding the data in some cover media like image file, audio file, video file, text file etc. Out of the various cover media available image file is the most widely u...

With the proliferation of digital media such as digital images, digital audio, and digital video, robust digital watermarking and data hiding techniques are needed for copyright protection, copy control, annotation, and authentication. While many techniques have been proposed for digital color and grayscale images, not all of them can be directly applied to binary text images. The difficulty li...

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 ...

Today at a time of globalization in which the whole planet become look like a small village and transport information through it with a push button in keyboard and at a time of huge evaluation in the digital world and for the millions of users to international net and some application importance, let us to use both cryptography and steganography as a means to protect the information from hackin...

Steganography has been practiced since ancient times. Many Linguistic Steganography (popularly known as Text based Steganography) algorithms have been proposed like Word Spacing, Substitution, Adjectives, Text Rotation, Mixed Case Font etc.. Information Hiding effectively means that the method/technique should be Robust, Secure and have good Embedding capacity. Measure of Similarity between cov...
