Claim:
1. A method for surveilling a monitored environment, the method comprising: obtaining an electronic signal from a sensor positioned in the monitored environment; extracting data about an individual present in the monitored environment from the electronic signal; classifying the individual according to a role fulfilled by the individual within the monitored environment, using the data extracted from the electronic signal, wherein the classifying is performed without recognizing an identity of the individual; determining an expected pattern of behavior associated with the role in the monitored environment; generating a trajectory that illustrates movements and locations of the individual within the monitored environment; detecting when the trajectory indicates an event that is inconsistent with the expected pattern of behavior, wherein the detecting is performed subsequent to the classifying; and activating a tangible responsive measure in response to the detecting.
