Image Steganography Based on Local Variance
This dissertation introduces two steganography techniques to improve the steganography algorithm using the Four least significant bits (LSB). One method refers to a grey-scale image, and the second refers to a digital color image.
Advanced Digital Image Steganography Using LSB, PVD, and EMD: Emerging Research and Opportunities
In the last few decades, the use of the Internet has grown tremendously, and the use of online communications has grown even more. The lack of security in private messages between individuals, however, allows hackers to collect loads of sensitive information. Modern security measures are required to prevent this attack on the world’s communication technologies. Advanced Digital Image Steganography Using LSB, PVD, and EMD: Emerging Research and Opportunities provides evolving research exploring the theoretical and practical aspects of data encryption techniques and applications within computer science. The book provides introductory knowledge on steganography and its importance, detailed analysis of how RS and PDH are performed, discussion on pixel value differencing principles, and hybrid approaches using substitution, PVD, and EMD principles. It is ideally designed for researchers and graduate and under graduate students seeking current research on the security of data during transit.
