ABOUT THIS BOOKCutting 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.
