ABSTRACT:
A system and processing techniques are provided for automatically detecting when an individual is under surveillance. At least one uniquely identifying characteristic associated with a vehicle or a person in proximity to the individual is detected as the individual moves about a geographic region, such as when the individual is traveling in a car. Positions in the geographic region where the uniquely identifying characteristics are collected and the times of these collections as the individual moves about the geographic region are also captured. Data is stored for detections of the uniquely identifying characteristics, times of detections and the positions where the uniquely identifying characteristics are detected as the individual moves about the geographic region. The stored data is analyzed to determine whether the individual is under surveillance based on (1) a match of the uniquely identifying characteristics with data stored in a database of known surveillance threats (vehicles, individuals or other characteristics) without regard to the time, distance and direction parameters associated with detection of those uniquely identifying characteristics, or (2) at least two detections of the same uniquely identifying characteristics sufficiently separated by time, distance and direction as said individual moves about said geographic region, or (3) based on either (1) or (2).
