Image-Based Location Authentication via Visual Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location-based authentication methods using GPS readings and IP addresses are vulnerable to hacker attacks, as these can be spoofed, leading to unauthorized access.
Innovation Solution
An authentication system that requires users to capture and compare images of their surroundings, such as the sky, using camera devices in the same location, to verify their physical location through computer vision transformation algorithms, preventing unauthorized access by ensuring a unique and dynamic authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If GPS readings and IP addresses are used for location-based authentication, then the authentication process is simple and easy to implement, but the system becomes vulnerable to spoofing attacks and hacker attacks
Solution Approach 1:
The patent introduces an intermediary verification mechanism using reference images captured by cameras at known locations. These reference images act as a mediator between the user's claimed location and the authentication system, providing an objective verification method that cannot be easily spoofed. The system compares user-submitted images against these reference images to confirm actual physical presence at the claimed location.
Solution Approach 2:
The patent replaces the traditional mechanical/location-based verification system (GPS coordinates and IP addresses) with an optical verification system using image capture and comparison. This substitution transforms the authentication mechanism from relying on easily spoofed digital signals to relying on visual verification of the physical environment, significantly improving security against spoofing attacks.
2Reliability
If image capture and comparison is implemented for authentication, then security against spoofing attacks is improved, but the device complexity and authentication process time increase
Solution Approach 1:
The patent leverages the universal functionality of mobile device cameras, which are already present in most smartphones and used for various purposes. By repurposing this existing hardware component for authentication, the system avoids adding specialized equipment while still achieving enhanced security. The camera serves multiple functions: capturing reference images during setup and capturing user-submitted images during authentication.
Solution Approach 2:
The patent implements a preliminary action phase where reference images are captured and stored in advance at various known locations. This preparation work is done beforehand, creating a database of authentic location images that can be quickly compared during actual authentication. This preliminary setup reduces the complexity and time required during the actual authentication process, as the system only needs to perform image comparison rather than capturing and analyzing images from scratch.
Data Source
AI summary
A computer-implemented method includes: (i) receiving location information that represents a physical location of a user; (ii) receiving a first image that has been captured by the user; (iii) in response to receiving the first image, obtaining a second image that has been captured by a camera and that depicts a particular object in an area around the physical location; (iv) determining whether the first image matches the second image; and (v) in response to determining that the first image matches the second image, determining that the user is authentic.
