Cutting edge technological advances in information and communication technologies (ICT), such as AI, blockchain, big data, IoT, sensing, edge computing, quantum computing, and distributed multimedia systems, have eased the process of transferring multimodal data and multimedia information over wide networks. AI techniques are already fruitful in protecting multimedia data such as deep learning for multimodal data or multimodal fusion. But the processing of huge sets of multimedia big data (including data from social media) requires reliable communication platforms since the rise of cyber threats have also been growing exponentially.

This edited book covers innovations, novel approaches, and methodologies in the domain of multimedia and multimodal data processing and security, including multimedia security authentication, AI-driven CPS security and resilience techniques, deep fake image detection, quantum approaches, and IoT-based intelligent systems for multimodal data analysis.

The book will be a useful reference for academic and industry researchers, lecturers and advanced students in computer science, networking, AI, multimedia digital content processing and security, cybersecurity, data protection and privacy; and to industry multimedia researchers and engineers interested in security and privacy challenges with a focus on AI and smart technologies. It will also of interest to specialists in digital rights, copyright and intellectual property.
