Abstract: Methods and systems for crowd surveillance in a public space are provided. The public space has one or more entry points each associated with a corresponding entry zone. Using an entry sensor network, each individual accessing the public space through one of the entry zones is tagged. Each tagged individual is then tracked using the entry sensor network and an interior sensor network. A mood analysis based on data acquired by at least the entry sensor network is performed and includes evaluating at least one physiological or behavioral parameter representative of an emotional state of the individual. A mood-based risk assessment of the individual is then performed based on the mood analysis.
