Multimedia security has become one of the most important topics for organizations and individuals. A huge amount of multimedia data, such as images, audio, and videos, are generated every day, and they are transmitted over the Internet. Any user with ill intentions may intercept those data and misuse, tamper, or modify them for personal gain and cause severe damage to the victim. This new book presents important state-of-the art multimedia security techniques and algorithms.

This book focuses on state-of-the-art methods and tools such as data encryption, steganography, watermarking, authentication, data hiding, biometric template security, quantum-based video cryptosystems, pansharpening, and digital signatures to help in protecting the unauthorized access/alteration of multimedia over the Internet and cloud. This book also covers the application of machine learning, blockchain, and AI-based methods for multimedia security. Mathematical models used in data hiding and data evaluation techniques are discussed thoroughly to provide a good understanding of the principles of multimedia security.

Written for those in the computer and information science disciplines, Multimedia Security: Tools, Techniques, and Applications provides a better understanding of the basics of multimedia processing and the tools and techniques available to protect multimedia content from unauthorized access and modification.
