Abstract

A method and system of preventing a loss/theft using a wireless personal area network (PAN) or a wireless local area network (LAN) which can receive, from a mobile device included in a surveillance target via a gateway, a location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile: device information being collected by a; sensor of the mobile device, and signal information communicated between the mobile device and a fixed device, can determine whether there is a loss or a theft by comparing surveillance target information and a permission standard, and can provide alert information including the location information of the surveillance target when there is the loss or the theft is provided.

Claims

1. A method of preventing a loss/theft using a wireless personal area network (PAN) or a wireless local area network (LAN), the method comprising:

receiving, from a mobile device included in a surveillance target via a gateway, a location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile device information being collected by a sensor of the mobile device, and signal information communicated between the mobile device and a fixed device;

determining whether there is a loss or a theft by comparing surveillance target information generated using a previous location information of the surveillance target and the received location information of the surveillance target, and a permission standard associated with the surveillance target, the previous location and the permission standard being extracted from a database; and

providing a pre-registered terminal with alert information including the location information of the surveillance target when it is determined that there is the loss or the theft.

2. The method of claim 1, wherein the fixed device is fixed in space in which the surveillance target is located, and

further comprising:

receiving, via the fixed device and the gateway, the mobile device information, an identifier of the mobile device, the signal information communicated between the mobile device and the fixed device, and an identifier of the fixed device.

3. The method of claim, 1, wherein the mobile device and the fixed device communicate with each other.

4. The method of claim 1, wherein the receiving comprises:

receiving, from the mobile device included in the surveillance target via the gateway, an identifier of the surveillance target and the location information of the surveillance target generated by using the mobile device information being collected by the sensor of the mobile device including at least one of movement information, weight information, and vibration information of the surveillance target and the signal information communicated between the mobile device and the fixed device.

5. The method of claim 1, wherein, when an identifier of the surveillance target is received, the determining comprises:

calculating a distance from the received location information of the surveillance target to a previous location information of the surveillance target, the previous location being extracted from the database by corresponding to the identifier; and

determining whether there is the loss or the theft by comparing the calculated distance and the permission standard associated with the surveillance target, the permission standard being extracted from the database by corresponding to the identifier.

6. The method of claim 1, further comprising:

receiving, via the gateway storing network information of the mobile device and the fixed device, an identifier of the mobile device and an identifier of the fixed device.

7. The method of claim 6, further comprising:

performing associated surveillance by sharing, with another gateway, the identifier of the mobile device, the identifier of the fixed device, and the network information when the surveillance target moves to a section managed by the other gateway.

8. The method of claim 1, wherein the providing comprises:

displaying and providing the alert information based on a specification of the terminal.

9. The method of claim 1, further comprising:

providing the location information of the surveillance target to the terminal when a request for the location information of the surveillance target is received from the terminal.

10. A system for preventing a loss/theft using a wireless PAN or a wireless LAN, the system comprising:

an interface unit to receive, from a mobile device included in a surveillance target via a gateway, a location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile device information being collected by a sensor of the mobile device, and signal information communicated between the mobile device and a fixed device;

a determination unit to determine whether there is a loss or a theft by comparing surveillance target information generated using a previous location information of the surveillance target and the received location information of the surveillance target, and a permission standard associated with the surveillance target, the previous location and the permission standard being extracted from a database; and

a location information providing unit to provide a pre-registered terminal with alert information including the location information of the surveillance target when it is determined that there is the loss or the theft.

11. The system of claim 10, wherein the fixed device is fixed in space in which the surveillance target is located, and

the interface unit receives, via the fixed device and the gateway, the mobile device information, an identifier of the mobile device, the signal information communicated between the mobile device and the fixed device, and an identifier of the fixed device.

12. The system of claim 10, wherein the mobile device and the fixed device-communicate with each other.

13. The system of claim 10, wherein the interface unit receives, from the mobile device included in the surveillance target via the gateway, an identifier of the surveillance target and the location information of the surveillance target generated by using the mobile device information being collected by the sensor of the mobile device including at least one of movement information, weight information, and vibration information of the surveillance target, and the signal information communicated between the mobile device and the fixed device.

14. The system of claim 10, wherein, when an identifier of the surveillance target is received, the determination unit calculates a distance from the received location information of the surveillance target to a previous location information of the surveillance target, the previous location being extracted from the database by corresponding to the identifier, and

determines whether there is the loss or the theft by comparing the calculated distance and the permission standard associated with the surveillance target, the permission standard being extracted from the database by corresponding to the identifier.

15. The system of claim 10, wherein the interface unit receives, via the gateway storing network information of the mobile device and the fixed device, an identifier of the mobile device and an identifier of the fixed device.

16. The system of claim 15, wherein the location information providing unit performs associated surveillance by sharing, with another gateway, the identifier of the mobile device, the identifier of the fixed device, and the network information when the surveillance target moves to a section managed by other gateways.

17. The system of claim 10, wherein the location information providing unit displays and provides the alert information based on a specification of the terminal.

18. The system of claim 10, wherein the location information providing unit provides the location information of the surveillance target to the terminal when a request for the location information of the surveillance target is received from the terminal.
