Surveillance Detection System and Methods for Detecting Surveillance of an Individual
First Claim
1. A method for automatically detecting that an individual is under surveillance, comprising:
- detecting at least one uniquely identifying characteristic associated with a vehicle or a person in proximity to said individual as said individual moves about a geographic region, wherein detecting at least one uniquely identifying characteristic comprises one or more of;
capturing still or video images of vehicles or persons in proximity to said individual to produce image data of a person or vehicle as said uniquely identifying characteristic;
receiving over-the-air signal transmissions or emissions from a device on a person or vehicle in proximity to said individual to produce received signal data as said uniquely identifying characteristic;
receiving radar signals reflected back from objects or persons in proximity to said individual to produce radar data as said uniquely identifying characteristic;
receiving optical energy scattered by a vehicle or person in proximity to said individual to produce spectroscopy data as said uniquely identifying characteristic;
receiving infrared energy emitted by a vehicle or person in proximity to said individual as said uniquely identifying characteristic; and
recovering a unique identifiers from a transmission made from a communication device as said uniquely identifying characteristic;
detecting a position in said geographic region where the uniquely identifying characteristics are detected as said individual moves about said geographic region and times when the detections are made; and
storing data for detections of said uniquely identifying characteristics, positions where said uniquely identifying characteristics are detected and time when detections are made 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).

9. A system comprising:
-
at least one sensor device that detects data that comprises at least one uniquely identifying characteristic associated with a vehicle or a person in proximity to an individual and outputs data representative thereof, wherein said at least one sensor comprises one or more of; a camera device that captures still or video images of vehicles or persons in proximity to said individual to produce image data of a person or vehicle as said uniquely identifying characteristic; a receiver that receives over-the-air signal transmission or emissions from a device on a person or vehicle in proximity to said individual to produce received signal data as said uniquely identifying characteristic; radar monitoring equipment that transmits signals and receives reflected signals back from objects or persons in proximity to said individual to produce radar data as said uniquely identifying characteristic; remote spectroscopy monitoring equipment that emits optical energy and analyzes reflected or scattered optical energy to produce spectroscopy data as said uniquely identifying characteristic; infrared monitoring equipment that produces infrared imaging data as said uniquely identifying characteristic; laser radar monitoring equipment to produce laser radar data as said uniquely identifying characteristic; synthetic aperture radio monitoring equipment to produce synthetic aperture radar data as said uniquely identifying characteristic; and signal processing equipment that recovers a unique identifier from a transmission made by a communication device; 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 characteristic is detected; and a control processor coupled to said at least one sensor device and said positioning receiver 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 at least one sensor device detects uniquely identifying characteristics for vehicles or persons in vehicles as said individual moves about said geographic region. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
