Surveillance detection system and methods for detecting surveillance of an individual
First Claim
1. A system for detecting that an individual is under surveillance, comprising:
- a. at least one sensor device that detects data that comprises at least one uniquely identifying characteristics associated with a vehicle or a person in proximity to said individual and outputs data representative thereof;
b. a positioning receiver device that receives signals from several sources and from which signals it computes a position of said individual and outputs data representative thereof and of times where said at least one uniquely identifying characteristics is detected; and
c. a control processor coupled to said at least one sensor device and said positioning receive device that stores data output by said at least one sensor device for vehicles or persons in proximity to said individual as said individual moves about a geographic region together with data output by said positioning receiver device that indicates positions in said geographic region where said sensor device detects uniquely identifying characteristics for vehicles or persons in vehicles as said individual moves about said geographic region, and wherein said control processor analyzes the stored data to determine whether said individual is under surveillance based on 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.

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).

21. A system for detecting that an individual is under surveillance, comprising:
-
a. a first subsystem that collects data pertaining to vehicles or persons in proximity to said individual as said individual moves around a geographic region; b. a second subsystem coupled to the first subsystem that processes said data to generate uniquely identifying characteristics associated the vehicles or persons in proximity to said individual as said individual moves around a geographic region; c. a third subsystem that determines a position within said geographic region and times associated with detection of said uniquely identifying characteristics; and d. a fourth subsystem coupled to the second subsystem and third subsystem, wherein the fourth subsystem stores data for said uniquely identifying characteristics together with the time and positions associated with detections of said uniquely identifying characteristics are detected; and e. a fifth subsystem that is coupled to the fourth subsystem and that analyzes the data stored by the fourth subsystem to determine whether said individual is under surveillance based on either a match of said uniquely identifying characteristics with data for known surveillance threats or based on 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.
