Detection of hostile intent from movement patterns

摘要

An embodiment of the present invention relates to a method comprising identifying a suspect; determining that the suspect has moved a first distance in a target zone around a target during a first time period; determining a suspect-target distance between the suspect and the target; determining a suspect-potential destination distance between the suspect and a potential destination in the target zone for the suspect; determining that the suspect has moved a second distance in the target zone during a second time period; determining a suspect zone around the suspect; determining a movement characteristic index associated with the suspect zone when the suspect has moved the second distance, and determining, by a computer, a probability of hostility of the suspect, wherein the probability of hostility is obtained from the movement characteristic index and a ratio of the suspect-target distance and the suspect-potential destination distance.
