Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality (AR) and virtual reality (VR) environments, existing data encryption methods face challenges in securing data without exposing symmetric password keys, which can be intercepted, and asymmetric encryption is inefficient for large data transfers due to its time-consuming nature.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If symmetric encryption is used for data transfer, then encryption efficiency is improved, but security deteriorates because the symmetric password key can be intercepted during exchange
Solution Approach 1:
The patent extracts the password key generation process from the traditional key exchange mechanism. Instead of exchanging the symmetric password key between devices, the system generates the key locally on each device using eye gaze tracking, thereby eliminating the security vulnerability of key transmission while maintaining symmetric encryption efficiency
Solution Approach 2:
The patent introduces eye gaze tracking as an intermediary mechanism to bridge the security and efficiency requirements. The eye gaze data serves as a shared secret that both devices can independently process to generate the same symmetric key, acting as a mediator that enables secure key agreement without direct key exchange
2Reliability
If asymmetric encryption is used to avoid key exposure, then security is improved, but productivity deteriorates due to time-consuming encryption for large data transfers
Solution Approach 1:
The patent performs preliminary action by generating the symmetric password key in advance through eye gaze tracking before the actual data transfer begins. This pre-established key can then be used for efficient symmetric encryption during the data transfer process, combining the security of pre-shared keys with the speed of symmetric encryption
Solution Approach 2:
The patent segments the encryption process into two distinct phases: (1) a preliminary key agreement phase using eye gaze tracking to establish a symmetric key securely, and (2) a data transfer phase using the established symmetric key for efficient encryption. This segmentation allows each phase to use the most appropriate encryption method for its specific requirements
3Reliability
If manual password entry is required for authentication, then security control is improved, but ease of operation deteriorates due to inconvenient password creation
Solution Approach 1:
The patent implements self-service by enabling the system to automatically generate password keys through eye gaze tracking without requiring manual user input. The user's natural eye movements serve as the input mechanism, and the system autonomously processes this data to create secure passwords, eliminating the burden of manual password creation while maintaining security
Solution Approach 2:
The patent substitutes the mechanical interaction of manual keyboard input with an optical/biological mechanism - eye gaze tracking. This replacement eliminates the need for physical typing or clicking to enter passwords, using instead the user's natural eye movements captured by sensors, thereby significantly improving ease of operation while maintaining security control

AI summary
In one embodiment, a method includes receiving an eye gaze of a source user generated by a source augmented reality or virtual reality device (source AR/VR device) on a receiver AR/VR device. The method also includes determining gazed content from the eye gaze of the source user using a password key phrase determination feature. In addition, the method includes generating a symmetric password key utilizing the gazed content according to a set of password determination rules. Moreover, the method includes performing an operation using the receiver AR/VR device, the operation being secured by the symmetric password key. The symmetric password key is not exchanged with any other device. Other systems, methods, and computer program products for generating a symmetric password key from an eye gaze are presented in accordance with more embodiments.
