Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information exchange systems fail to securely, conveniently, and intuitively allow users to access specific information hidden in encoded patterns, as they require analysis or remote processing, compromising security and user experience.
Innovation Solution
A method and system that overlay a decoding template onto an encoded pattern in a user's eye fundus, allowing direct visualization of the original pattern, using encoding and decoding templates generated from pseudo-random sequences, and enhancing the recovery pattern for better visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional information exchange systems are used, then information can be transmitted, but users cannot securely and intuitively access specific information hidden in encoded patterns without analysis or remote processing
Solution Approach 1:
The patent projects decoding templates directly onto the user's retina (eye fundus), transitioning from conventional external display to internal retinal projection. This dimensional change enables secure, intuitive information access by decoding patterns directly in the user's visual field without requiring remote processing or analysis, thus improving both convenience and security simultaneously
2Reliability
If information is encoded for security, then information security is improved, but users cannot directly see the original pattern without complex processing
Solution Approach 1:
The patent introduces a decoding template as an intermediary element that is projected onto the user's retina. This template acts as a mediator between the encoded pattern and the user's perception, enabling direct visualization of the original pattern without complex external processing, thus maintaining security while improving intuitiveness
3Ease of operation
If remote processing is used to decode information, then information can be accessed, but security and user experience are compromised
Solution Approach 1:
The patent enables the user's own visual system to perform the decoding function by projecting the decoding template directly onto the retina. This self-service approach eliminates the need for remote processing, allowing users to securely and intuitively access information independently, thus improving both user experience and information security

AI summary
The application discloses an information exchange method and an information exchange system, the method including: overlaying at least one decoding template onto an encoded pattern in at least one eye fundus of a user, to obtain a recovery pattern presented in the at least one eye fundus of the user, where the recovery pattern corresponds to an original pattern of the encoded pattern, and the at least one decoding template corresponds to at least one encoder used when the encoded pattern is obtained. According to the technical solutions of the embodiments of this application, an encoded pattern is decoded by overlaying a decoding template to an encoded pattern in at least one eye fundus of a user, so that a specific user can conveniently and intuitively see information hidden in the encoded pattern directly on the spot.
