A Framework for Copyright Protection with Digital Watermarking using Cryptography and Steganography

Abstract

Information security has become the most needed and challenging problem in this internet based era as most of the communication takes based as digital files across the network. One of the ways to effectively secure the information is to make the information hidden that is being shared. With the mammoth improvement in technology, almost all the information that is being shared is digitized and digital images is one such digital file that is being shared more commonly. Digital watermarking is an effective way of protecting the ownership of the images. This paper aims to improve the information hiding scheme in digital images for sharing information and protecting the ownership of the file by proposing a new methodology to hide the information being shared using both cryptographic and steganographic methods. This paper also compares the performance measure of the proposed methodology with various existing methodologies.
