Abstract

A method and system relating to a restraining or protective order violation scenario where the movements of the restrainee and the movements of the protected person are monitored in order to detect if a predatory pattern is at hand. The movement, velocity, and positioning of the restrainee can be described as a set of patterns with respect to the protected person. The patterns can be determined based upon the distance between the two, and the direction and speed of both the restrainee and the protected person. Depending on the detected pattern, a notification system incorporating the present invention alerts the local law enforcement authorities with a warning or alarm, and/or sends a warning/alarm signal to the protected person if a predatory pattern is detected.

Claims

1. A system for identifying predatory patterns based on movement and proximity correlations between a predator and a victim, the system comprising:

a monitoring facility adapted to continuously receive positional information from the predator and the victim for a given time period, the monitoring facility including;

a computer system adapted to identify correlations between position and movement of the predator and the victim and to determine the existence of one or more predatory patterns based upon the correlations; and

signaling means for alerting the victim if the computer system determines the existence of one or more predatory pattern.

2. The system of claim 1, wherein the positional information includes at least the direction of movement, and the velocity of the predator and the victim, and the relational positioning between the predator and the victim.

3. The system of claim 1, wherein the monitoring facility further includes signaling means for alerting a law enforcement agency if the computer determines the existence of a predatory pattern.

4. The system of claim 2, wherein an accidental encounter exists if:

the predator moves within a restricted distance of the victim;

there is no correlation between the direction of movement and the velocity of the predator and the direction of movement and the velocity of the victim; and

the predator is not near a geographic region or path known by the victim, whereby an accidental encounter does not give rise to a predatory pattern.

5. The system of claim 2, wherein a surveillance pattern exists if there is a correlation between the direction of movement and velocity of the predator and the direction of movement and velocity of the victim even if the predator is not within a restricted distance of the victim.

6. The system of claim 1, wherein an ambush pattern exists if the predator is substantially stationary for an extended period of time with respect to a geographic region or path known by the victim.

7. The system of claim 1, wherein an attack pattern exists if the distance between the predator and the victim is less than a pre-determined distance and is decreasing with time, and the predator is moving with a greater velocity than the victim.

8. A method of identifying predatory patterns based on movement and proximity correlations between a predator and a victim, the method comprising:

continuously receiving positional information from the predator and the victim for a given time period;

identifying correlations between position and movement of the predator and the victim;

determining the existence of one or more predatory patterns based upon the correlations; and

transmitting a warning signal upon determination of the existence of one or more predatory pattern.

9. The method of claim 8, wherein the warning signal can be transmitted to at least the victim and a law enforcement agency.

10. The method of claim 8, wherein the positional information includes at least the direction of movement, and the velocity of the predator and the victim, and the relational positioning between the predator and the victim.

11. The method of claim 10, wherein an accidental encounter exists if:

the predator moves within a restricted distance of the victim;

there is no correlation between the direction of movement and the velocity of the predator and the direction of movement and the velocity of the victim; and

the predator is not near a geographic region or path known by the victim, whereby an accidental encounter does not give rise to a predatory pattern.

12. The method of claim 10, wherein a surveillance pattern exists if there is a correlation between the direction of movement and velocity of the predator and the direction of movement and velocity of the victim even if the predator is not within a restricted distance of the victim.

13. The method of claim 10, wherein an ambush pattern exists if the predator is substantially stationary for an extended period of time with respect to a geographic region or path known by the victim.

14. The method of claim 10, wherein an attack pattern exists if the distance between the predator and the victim is less than a pre-determined distance and is decreasing with time, and the predator is moving with a greater velocity than the victim.

15. A computer program product comprising a computer usable medium having computer usable program code for identifying predatory patterns based on received positional information from the predator and the victim, the computer program product including:

computer usable program code for identifying correlations between position and movement of the predator and the victim; and

computer usable program code for determining the existence of one or more predatory patterns based upon the correlations.

16. The computer program product of claim 15, wherein the positional information includes at least the direction of movement, and the velocity of the predator and the victim, and the relational positioning between the predator and the victim.

17. The computer program product of claim 16, further comprising computer usable program code for determining the existence of an accidental encounter, wherein an accidental encounter exists if:

the predator moves within a restricted distance of the victim;

there is no correlation between the direction of movement and the velocity of the predator and the direction of movement and the velocity of the victim; and

the predator is not near a geographic region or path known by the victim, whereby an accidental encounter does not give rise to a predatory pattern.

18. The computer program product of claim 16, further comprising computer usable program code for determining the existence of a surveillance pattern, wherein a surveillance pattern exists if there is a correlation between the direction of movement and velocity of the predator and the direction of movement and velocity of the victim even if the predator is not within a restricted distance of the victim.

19. The computer program product of claim 16, further comprising computer usable program code for determining the existence of an ambush pattern, wherein an ambush pattern exists if the predator is substantially stationary for an extended period of time with respect to a geographic region or path known by the victim.

20. The computer program product of claim 16, further comprising computer usable program code for determining the existence of an attack pattern, wherein an attack pattern exists if the distance between the predator and the victim is less than a pre-determined distance and is decreasing with time, and the predator is moving with a greater velocity than the victim.
