Abstract

A system and method of detecting and thwarting the use of unauthorized imaging systems at theatrical performances. Sensors are deployed at a theatrical event to detect a focusing signal and/or the RF signal of an unauthorized imaging device. De-focusing signals are used to disrupt the auto focus system of imaging devices that do not use IR focusing systems. A thwarting signal comprising invisible light frequencies may be combined to produce a thwarting signal that is received by the CCD of an imaging device as white light thereby rendering the recorded image unusable. Emission signatures of imaging devices are stored in a datastore and distributed to users of thwarting systems via a network. Emission signatures are associated with thwarting signals to allow detection and thwarting systems to respond quickly to the use of an unauthorized imaging device.

Claims

1. A system for preventing the pirating of a theatrical experience comprising:

a local network;

a local signature library adapted to;

store emission signatures of imaging devices; and

store thwarting measures associated with the emission signatures;

a thwarting system connected to the local network, wherein the thwarting system comprises;

a sensor arranged spatially proximate to an area wherein the theatrical experience is taking place and adapted to receive emission signals within the area wherein the theatrical experience is taking place; and

a local thwarting system control server connected to the local network, wherein the local thwarting system control server is adapted to;

receive the emission signals from the thwarting system;

determine if the emission data is indicative of the presence of an imaging device;

if the emission data is indicative of the presence of the imaging device, determine whether the emission data matches an emission signature of an imaging device stored in the local emission signature library; and

if the emission data matches the emission signature stored in the emission signature library, then take a remedial action associated with the emission signature as stored in the emission signature library.

2. The system of claim 1 further comprising:

a thwarting signal distribution network (TSDN);

a central emission signature library;

a central control server, wherein the central control server communicates with the local thwarting system control server via a thwarting signal distribution network (TSDN) and wherein the central control server is adapted to;

access the central emissions signature library;

acquire new emissions signatures and associated new thwarting signals from the central signature library; and

send the new emissions signatures and the associated new thwarting signals to the local thwarting control server; and

wherein the local emissions signature library stores the new emissions signatures and the associated new thwarting signals from the local thwarting system control server.

3. The system of claim 2, wherein the TSDN is the internet.

4. The system of claim 2, wherein the TSDN is a wireless network.

5. The system of claim 2, wherein the TSDN is a wired network.

6. The system of claim 1, wherein the remedial action comprises transmitting a control instruction to affect operation of the imaging device.

7. A method for preventing the pirating of a theatrical experience comprising:

receiving emission signals from a sensor arranged spatially proximate to an area wherein the theatrical experience is taking place and adapted to receive emission signals within the area wherein the theatrical experience is taking place;

sending the emission signals to a local thwarting system control server connected to the local network'"'"'

determining at the local thwarting system control server if the emission data is indicative of the presence of an imaging device;

if the emission data is indicative of the presence of the imaging device, determining whether the emission data matches an emission signature of an imaging device stored in a local emission signature library; and

if the emission data matches the emission signature stored in the emission signature library, then taking a remedial action associated with the emission signature as stored in the emission signature library.

8. The method of claim 7 further comprising:

accessing a central emissions signature library;

acquiring new emissions signatures and associated new thwarting signals from the central signature library; and

sending the new emissions signatures and the associated new thwarting signals to the local thwarting control server via a thwarting signal distribution network (TSDN);

storing the new emissions signatures and the associated new thwarting signals from the local thwarting control server in the local emissions signature library.

9. The method of claim 8, wherein the TSDN is the internet.

10. The method of claim 8, wherein the TSDN is a wireless network.

11. The method of claim 8, wherein the TSDN is a wired network.

12. The method of claim 7, wherein the taking the remedial action comprises transmitting a control instruction to affect operation of the imaging device.
