Data Hiding in Binary Images Using Orthogonal Embedding - A High Capacity Approach

Abstract

The growth of high speed computer networks and the Internet, in particular, has increased the ease of Information Communication. In comparison with Analog media, Digital media offers several distinct advantages such as high quality, easy editing, high fidelity copying, compression etc. But this type advancement in the field of data communication in other sense has hiked the fear of getting the data snooped at the time of sending it from the sender to the receiver. Information Security is becoming an inseparable part of Data Communication. In order to address this Information Security, Digital Watermarking plays an important role. Watermarking Techniques are used to hide a small amount of data in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. This paper proposed a high capacity data hiding approach for binary images in morphological transform domain for authentication purpose so that the image will look unchanged to human visual systems
