System and methods for secure communication using an enhanced GPS receiver
First Claim
1. A method for communicating location information between a mobile device and a remote terminal, said mobile device having a Global Positioning System (GPS) receiver, comprising:
- obtaining location information from said GPS receiver, said location information representing a location of said mobile device;
obtaining a GPS chip identification number from said GPS receiver;
using said GPS chip identification number as an encryption key to encrypt said location information into an encrypted location information at said GPS receiver;
transmitting said encrypted location information to said remote terminal.

Abstract
An enhanced GPS receiver is provided for secure location information communication. The GPS receiver includes a GPS signal receiving unit, a GPS signal processing unit, and en encryption module. The GPS signal receiving unit is used to receive the GPS signals. The GPS signal processing unit coupled to the GPS receiving unit is used to obtain the location information of the mobile device. The encryption module encrypts the location information by using a GPS chip identification number embedded in the GPS receiver as an encryption key. The GPS receiver further optionally includes a compression module for compressing the location information before encryption.
