Solution Overview

Problem

Conventional GPS location information transmission is susceptible to tampering and interception due to the lack of encryption within the GPS receiver, making it insecure, especially when used in mobile devices without integrated encryption modules.

Innovation Solution

An enhanced GPS receiver is developed with a built-in GPS chip identification number used as an encryption key to encrypt location information within the receiver, allowing secure transmission over wireless networks using a compression and encryption module, and decryption at the receiving terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If location information is transmitted over wireless network without encryption, then transmission simplicity is maintained, but security is compromised making it susceptible to tampering and interception

Engineering Contradiction:
ImprovesecurityVSAvoidencryption module integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by implementing encryption within the GPS receiver before data transmission occurs. The location information is encrypted at the source (GPS receiver) using an encryption module integrated into the receiver itself, rather than relying on encryption at the receiving end or during transmission. This preliminary encryption ensures that even if data is intercepted during transmission, it remains secure because the encryption is already applied before leaving the GPS receiver.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If encryption module is integrated in mobile device, then encryption can be provided for that device, but GPS receiver becomes insecure when installed in other mobile devices without encryption modules

Engineering Contradiction:
ImproveGPS receiver compatibilityVSAvoidencryption security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies universality by integrating the encryption module directly into the GPS receiver, making the encryption capability universal and device-agnostic. This means the GPS receiver can be installed in any mobile device and will consistently provide encryption functionality regardless of whether the host device has its own encryption module. The encryption capability becomes an inherent feature of the GPS receiver itself, ensuring security across all installations and applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

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.
