Auxiliary Device Authentication Using Dynamic Screen Frame Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for auxiliary devices in entertainment systems, such as games consoles, are inconvenient and vulnerable to security breaches, particularly when using QR codes or static images that can be easily spoofed, disrupting user experience and compromising personal data security.
Innovation Solution
An authentication method that uses frame- or feature-matching of dynamic content displayed on an authenticated device with images captured by an auxiliary device, eliminating the need for manual input of login details and enhancing security by requiring a threshold of dynamic content variation or specific user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If QR code or static image authentication is used, then the authentication process is simplified, but security is compromised due to easy spoofing
Solution Approach 1:
The patent transforms static authentication images into dynamic content by utilizing real-time video game footage displayed on the primary device. The auxiliary device captures live gameplay frames, which continuously change and cannot be statically reproduced, thereby preventing spoofing while maintaining the simplicity of the authentication process.
Solution Approach 2:
The patent uses optical copying through camera capture of displayed content. Instead of transmitting authentication data electronically, the system captures visual information from the display screen using a camera, creating a visual copy that must be processed and matched in real-time, adding a layer of complexity that prevents simple replication.
2Reliability
If manual login input is required for auxiliary devices, then security is enhanced, but user experience deteriorates due to laborious process
Solution Approach 1:
The system enables self-service authentication by allowing the auxiliary device to automatically capture and process authentication data from the display screen. The user simply needs to point the camera at the screen, and the system automatically extracts and verifies the authentication information without requiring manual typing or complex interactions.
Solution Approach 2:
The patent replaces the mechanical input method (manual typing of login credentials) with an optical system. The camera captures visual information from the display, and image processing algorithms automatically extract and verify authentication data, substituting physical keyboard input with optical detection and digital processing.
3Reliability
If QR code display is shown during authentication, then verification is enabled, but content display is interfered with
Solution Approach 1:
The patent extracts the authentication verification function from the primary display content. Instead of overlaying QR codes or verification elements on the game screen, the system separates the authentication process into a distinct visual channel by displaying verification information on the auxiliary device's screen, allowing the primary display to remain fully dedicated to content delivery.

AI summary
A system for performing a login process for a user profile at an auxiliary device, the system comprising a first obtaining unit configured to obtain information associated with each of a plurality of image frames displayed by a first device, the first device being logged in with the user profile, a second obtaining unit configured to obtain a plurality of images captured by a camera associated with the auxiliary device, a comparison unit configured to compare the information associated with plurality of image frames displayed by the first device with a plurality of corresponding images captured by the camera to identify a degree of similarity for each corresponding image pair, wherein corresponding images are those associated with a same respective display and capture time, and an authentication unit configured to execute a login to the auxiliary device with the user profile in response to a determination that the degree of similarity meets or exceeds a threshold value for at least a subset of the plurality of corresponding image pairs.
