Portable Terminal Authentication Using Delayed Location Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for mobile devices are either insecure or technically complex, often relying on user input prone to errors or requiring additional hardware, which can lead to unauthorized access and identity theft.
Innovation Solution
A method that authenticates a portable terminal by storing location data with a time delay, extracting characteristic features from this data using an extraction logic, and comparing it with immediate pre-authentication data to verify the device's legitimacy based on its movement profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (PIN, password, smart card) are used, then user identity can be verified, but the system becomes vulnerable to identity theft and access errors when devices are lost or stolen
Solution Approach 1:
The system performs preliminary actions by continuously collecting and storing location data in advance before authentication is needed. This historical location information is then used during authentication to verify the device's legitimacy, eliminating the need for traditional vulnerable authentication methods while maintaining high security.
Solution Approach 2:
The patent introduces location data as an intermediary element between the user and the authentication system. Instead of directly using passwords or PINs that can be stolen, the system uses location history as a mediator to verify device ownership, making it much harder for thieves to impersonate users even with physical access to the device.
2Reliability
If extensive hardware such as card readers is used for authentication, then authentication reliability improves, but device complexity and technical requirements increase
Solution Approach 1:
The patent replaces mechanical authentication hardware (card readers, smart card readers) with a software-based location analysis system. The authentication is performed by comparing location data patterns through algorithmic processing, eliminating the need for additional physical hardware while maintaining or improving authentication reliability.
Solution Approach 2:
The location data collection system serves multiple functions: it continuously tracks device location for security purposes, provides authentication verification, and can potentially be used for other services. This multi-functionality eliminates the need for separate dedicated authentication hardware, reducing overall device complexity.
3Measurement precision
If users must provide extensive authentication data manually, then authentication accuracy can be improved, but user convenience and ease of operation decrease
Solution Approach 1:
The system implements self-service by automatically collecting, storing, and analyzing location data without requiring any manual user input during authentication. The device itself generates the authentication evidence through its movement patterns, eliminating the need for users to manually enter passwords or remember authentication data while maintaining high accuracy.
4Reliability
If location data is collected continuously for authentication, then authentication security improves, but energy consumption and data storage requirements increase
Solution Approach 1:
The system extracts only the essential authentication-critical information from continuous location data - specifically, the characteristic location patterns and movement profiles. Rather than storing and processing all raw location data continuously, it extracts and stores only the relevant authentication features, significantly reducing energy consumption and storage requirements while maintaining security.
