Gaze-Based Authentication for Multi-Device Credential Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face a time-consuming and cumbersome process when signing in or authenticating across multiple electronic devices or user accounts, often requiring manual entry of credentials and potentially using weak passwords for ease of remembrance.
Innovation Solution
A system utilizing a device with a camera and eye tracker to detect and transmit authentication credentials to another device when the user's gaze is directed at it, eliminating the need for manual input and simplifying the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual authentication credentials entry is required for each device, then security can be maintained through password protection, but the authentication process becomes time-consuming and cumbersome
Solution Approach 1:
The system performs preliminary authentication by detecting the user's gaze direction before the authentication process is initiated. The eye tracker identifies when the user is looking at a second device, automatically triggering credential transmission without requiring manual password entry. This preliminary detection resolves the contradiction by preparing and executing authentication in advance of the actual login attempt.
Solution Approach 2:
The patent replaces the mechanical manual typing of passwords with an optical detection system (eye tracker). Instead of manually entering credentials through physical input devices, the system uses gaze detection to automatically identify user intent and transmit credentials. This substitution eliminates the time-consuming manual entry process while maintaining security through biometric-based authentication.
2Ease of operation
If users use weak passwords to ensure easy remembrance, then authentication speed improves, but security is compromised
Solution Approach 1:
The system provides self-service authentication by automatically detecting user intent through gaze tracking and transmitting credentials without requiring the user to manually input or remember complex passwords. The eye tracker serves as a self-activating mechanism that identifies when authentication is needed and executes the process autonomously, eliminating the need for users to balance password strength against memorization difficulty.
Solution Approach 2:
The patent introduces an intermediary system (eye tracker with automatic credential transmission) between the user and the authentication process. Instead of directly entering passwords, the user's gaze is detected and translated into automatic credential submission. This intermediary layer allows users to maintain strong security credentials without the burden of memorization, as the system bridges the gap between simple user intent (looking at a device) and complex authentication requirements.
3Adaptability or versatility
If multiple authentication credentials are stored for different devices, then access to multiple accounts is enabled, but the complexity of managing these credentials increases
Solution Approach 1:
The patent implements a universal authentication system where a single eye-tracking device can authenticate the user across multiple different devices and accounts. The credential transmission system is designed to work with any second device that displays authentication requirements, making the authentication mechanism universally applicable rather than device-specific. This eliminates the need for users to manage separate authentication processes for each device.
Solution Approach 2:
The system acts as an intermediary credential management layer that handles multiple device credentials through a single unified interface (the eye tracker). Instead of requiring users to manually manage and input credentials for each device, the intermediary system stores and manages multiple credential sets, automatically selecting and transmitting the appropriate credentials based on gaze detection. This reduces the perceived complexity for users while maintaining multi-device adaptability.

AI summary
In one implementation, a method of authenticating a user is performed by a first device including a camera, an eye tracker, one or more processors, and non-transitory memory. The method includes obtaining, via the camera, an image of a physical environment. The method includes detecting, in the image of the physical environment, a second device. The method includes determining, using the eye tracker, a gaze of a user. The method includes determining that the gaze of the user is directed to the second device. The method includes, in response to determining that the gaze of the user is directed to the second device, transmitting authentication credentials to the second device.
