Advances in security and privacy of multimodal interfaces

With the rapid development and increasing complexity of communication systems and interfaces using multiple modalities of communication in human-computer systems such as speech, tactile, gestures, gaze, head and body movements, facial expressions, gait, electroencephalogram (EEG) and electromyogram (EMG) signals, the user requirements for trust, security, and privacy are becoming more demanding. The main objective of this special issue was to provide a forum for researchers interested in the latest research results in the rapidly developing field of security and privacy in multimodal interfaces, therefore providing a valuable information venue to researchers as well as practitioners.
