Iris Contraction Data Embedding for Secure Electronic Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic commerce transactions, there is a risk of password theft and disputes over transaction content or behavior, particularly when electronic signatures are involved, necessitating a method to securely confirm and prevent denial of trade content or behavior.
Innovation Solution
A method and system using biological features, specifically the iris, where a terminal generates an intensity-variable light signal and projects it onto an iris to capture contraction information, which is then used to extract data, preventing users from denying transactions or behaviors by embedding data within the iris contraction patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password input methods are used for electronic commerce transactions, then user authentication can be performed, but the risk of password theft and unauthorized access increases
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication systems with a biological authentication system that uses iris contraction patterns. The terminal device projects light patterns onto the user's iris and captures the contraction responses, substituting the manual password input mechanism with an automatic biological response detection mechanism that cannot be easily stolen or replicated.
Solution Approach 2:
The patent changes the authentication parameter from static password strings to dynamic physiological responses (iris contraction patterns). By measuring the real-time contraction of the iris in response to projected light patterns, the system transforms authentication from a knowledge-based process to a physiological response-based process, enhancing security while eliminating password theft risks.
2Ease of operation
If electronic signatures are used in trade activities, then transaction confirmation can be achieved, but the ability to deny transaction content or behavior cannot be prevented
Solution Approach 1:
The patent creates a biological copy of the user's authentication response by capturing and storing the iris contraction pattern data. This biological signature serves as an immutable record of the user's confirmation action, similar to a digital signature but based on physiological responses that cannot be replicated or denied. The captured iris contraction data is stored and can be used to verify subsequent claims about the transaction.
Solution Approach 2:
The patent performs preliminary capture and storage of the iris contraction pattern at the moment of authentication. By recording the biological response before the transaction is completed, the system creates beforehand evidence that can prevent future denial. The iris contraction data is stored as proof of the user's genuine participation in the transaction.
3Ease of operation
If traditional authentication methods are used, then user convenience is maintained, but the integrity and authenticity of transaction data cannot be guaranteed
Solution Approach 1:
The patent enables the user's own biological system (iris) to serve as the authentication mechanism. The user simply looks at the terminal device while it projects light patterns onto their iris, and the system automatically captures the contraction response without requiring manual input. This self-service approach maintains convenience while ensuring integrity, as the authentication is based on the user's own physiological responses rather than external credentials.

AI summary
The present invention provides methods, systems and equipment for acquiring and extracting information using a biological feature. The method for acquiring information using a biological feature—includes: acquiring first data by a terminal; controlling, by the terminal, a light source to generate an intensity-variable light signal according to the first data, and projecting the intensity-variable light signal on an iris; acquiring, by the terminal, first iris information at least comprising first iris contraction information, in which the first iris contraction information is generated by the iris according to the intensity-variable light signal and comprises a first iris contraction activity; acquiring, by the terminal, second iris information at least comprising second iris contraction information; and extracting, by the terminal, second data from the second iris contraction information according to a preset rule.
