Abstract

A device and software utilizing Global Positioning Satellite (GPS) technologies for monitoring and recovering portable computing devices and, a method and system for acquiring such devices, protecting data on such devices, and for compensating owners of devices. A GPS mechanism of the invention provides real time tracking of missing devices that may be coordinated with security agencies to intercept and recover missing computing devices. When a stolen device is unrecoverable, the invention may receive a signal to initiate data recovery where a wireless network is available to recover data for the owner. Alternatively, the GPS mechanism instructs the device to encrypt or destroy stored data files to prevent commercial espionage or privacy violations. The invention discloses a software system and method for computing a purchase price of the GPS mechanism, computing compensation for loss of the device and lost data.

Claims

1. A system for protecting a portable computing device, the system comprising:

a circuit board having a connector disposed at a first side of the circuit board, the circuit board having a first face and a second face, the connector connecting to an interface port in the portable computing device;

a positioning device disposed on the first face of the circuit board, the positioning device identifying a location of the portable computing device;

a positioning antenna disposed on the circuit board, the positioning antenna connected to and communicating with the positioning device and allowing communication between the positioning device and one or more global positioning satellites;

a communication antenna disposed on a second side of the circuit board, the communication antenna communicatively coupled to the positioning device, the communication antenna configured to transmit the location of the portable computing device as identified by the positioning device to an authorized device in response to receipt of an alert signal by the communication antenna, the alert signal identifying that the portable computing device has been lost; and

a rechargeable battery disposed on the second face of the circuit board, the rechargeable battery to power at least the positioning device, the rechargeable battery distinct from a second rechargeable battery that is not disposed on the circuit board, the second rechargeable battery powering a subset of the portable computing device other than the positioning device, the positioning antenna, and the communication antenna.

2. The system of claim 1, wherein the connector digitally communicates with the portable computing device to prevent access to one or more electronically stored records stored at the portable computing device in response to the receipt of the alert signal by the communication antenna.

3. The system of claim 1, wherein the communication antenna continues outputting a location of the positioning device at predetermined intervals.

4. The system of claim 2, wherein preventing the use of the one or more electronically stored records includes erasing the one or more electronically stored records.

5. The system of claim 1, wherein preventing the use of the one or more electronically stored records includes encrypting the one or more electronically stored records.

6. The system of claim 2, wherein preventing the use of the one or more electronically stored records is delayed by a predetermined time interval after receipt of the alert signal by the communication antenna.

7. The system of claim 5, wherein the connector digitally communicates with the portable computing device to decrypt the one or more electronically stored records using a decryption key in response to receipt of a retrieval alert by the communication antenna, the retrieval alert including the decryption key, the retrieval alert indicating that the portable computing device has been retrieved.

8. The system of claim 2, wherein the one or more electronically stored records include at least one of a user data file, an executable software program, or an operating system.

9. The system of claim 1, wherein the rechargeable battery is distinct from a second battery, the second battery powering a remainder of the portable computing device, the remainder of the portable computing device not including the positioning device, the positioning antenna, and the communication antenna.

10. The system of claim 1, wherein the interface port of the portable computing device is a memory slot of the portable computing device.

11. The system of claim 1, wherein the interface port of the portable computing device is disposed on a motherboard of the portable computing device.

12. The system of claim 1, wherein the communication antenna is a cellular transceiver that communicates via a cellular telephone network.

13. The system of claim 12, wherein the communication antenna is coupled to a SIM card housing.

14. The system of claim 13, wherein the SIM card housing is disposed on the first face of the circuit board.

15. The system of claim 1, further comprising a charging port to provide electrical power to the rechargeable battery, the charging port disposed along one of the first side of the circuit board, the second side of the circuit board, or a third side of the circuit board.

16. The system of claim 1, wherein the communication antenna is one of flexible or flexed.

17. The system of claim 1, wherein the communication antenna transmits a location of the positioning device as an SMS text message to an authorized user device.

18. The system of claim 1, wherein the portable computing device is one of a laptop, a tablet, or a smartphone.

19. A method for protecting a portable computing device, the method comprising:

initiating communication of data between a connector and an interface port in the portable computing device, the connector disposed at a first side of a circuit board and connected to the interface port, the circuit board having a first face and a second face;

receiving an alert signal at a communication antenna, the alert signal identifying that the portable computing device has been lost, the communication antenna disposed on a second side of the circuit board and communicatively coupled to a positioning device disposed on the first face of the circuit board;

communicating with one or more global positioning satellites using a positioning antenna disposed on the circuit board, the positioning antenna connected to and communicating with the positioning device;

determining a first location using the positioning device, the first location being a location of the portable computing device based on one or more communications between the positioning antenna and the one or more global positioning satellites;

transmitting the first location of the portable computing device to an authorized device using the communication antenna in response to the receipt of the alert signal at the communication antenna;

providing power from a rechargeable battery to at least the positioning device;

providing power from a second rechargeable battery not disposed on the circuit board to a subset of the portable computing device other than the positioning device, the positioning antenna, and the communication antenna.
