Abstract

Editing, reproduction and distribution of the digital multimedia are becoming extremely easier and faster with the existence of the internet and the availability of pervasive and powerful multimedia tools. Digital watermarking has emerged as a possible method to tackle these issues. This paper proposes a scheme using which more data can be inserted into an image in different domains using different techniques. This increases the embedding capacity. Using the proposed scheme 24 binary images can be embedded in the DCT domain and 12 binary images can be embedded in the spatial domain using LSB substitution technique in a single RGB image. The proposed scheme also provides an extra level of security to the watermark image by scrambling the image before embedding it into the host image. Experimental results show that the proposed watermarking method results in almost invisible difference between the watermarked image and the original image and is also robust against various image processing attacks.

Highlights

A large number of Digital Watermarking schemes have been studied to protect the intellectual property rights of the owner
Where 255 represents the maximum value of each pixel and RMSE is the square root of Mean Squared Error (MSE) between the original and marked images
The proposed watermarking scheme provides 24 binary images to be embedded in the frequency domain and 12 more binary images in the spatial domain

Summary

Introduction

A large number of Digital Watermarking schemes have been studied to protect the intellectual property rights of the owner. All these schemes implement either visible or invisible watermarks. An example of visible watermarking is seen in television channels when their logo is visibly superimposed in the corner of the screen. Video and still images are the best hosts for invisible watermarks to embed the copyright data. One of the types of media is digital imagery, which can be copied and widely distributed without any significant loss of quality. Protecting the property rights of the owners of these images is important. A means to protect this data is to apply a digital watermark
