Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current internet transactions face significant security and privacy concerns due to the risk of data hijacking during online data transmission, as traditional validation methods rely on paper work or in-person verification, which are not feasible for online transactions.
Innovation Solution
A self-sovereign information management framework that uses iris-based authentication, generating focus dots on a display to capture live iris images, ensuring the user is live and authenticating them without transmitting sensitive information over the network, employing cloaked identifiers for secure data access and zero-knowledge proof to maintain privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional validation methods (paper work or in-person verification) are used, then security and privacy are maintained, but online transaction feasibility is compromised
Solution Approach 1:
The patent replaces physical in-person verification mechanisms with biometric authentication (iris scanning) and cryptographic validation systems. The mechanical process of presenting physical ID documents is substituted with automated biometric capture and zero-knowledge proof verification, enabling secure online validation without physical presence while maintaining security standards.
Solution Approach 2:
The patent introduces trusted third-party services and cryptographic intermediaries that facilitate secure validation between transacting parties. These intermediaries handle the complex security protocols, allowing users to transact online with the same level of security as in-person verification without requiring physical meetings.
2Ease of operation
If personal information is transmitted over the network for validation, then transaction verification is enabled, but data hijacking risk increases
Solution Approach 1:
The patent extracts and validates only the specific attributes necessary for transaction verification (e.g., age, identity confirmation) without transmitting full personal information. The biometric authentication extracts iris pattern data for verification, and zero-knowledge proofs extract only the boolean result of validation, leaving sensitive personal data isolated and non-transmittable.
Solution Approach 2:
The patent transforms personal information from transmittable data formats into non-transmittable cryptographic proofs. Personal identifiers are converted into biometric templates and zero-knowledge proofs that can be verified without revealing the underlying personal data, changing the parameter state from information-rich to verification-only.
3Measurement precision
If biometric authentication is implemented, then authentication accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal biometric authentication framework that handles multiple authentication types (iris scanning, fingerprint, facial recognition) through a common cryptographic validation infrastructure. This multi-functional approach achieves high authentication accuracy across different biometric modalities while reducing overall system complexity through standardized processing protocols.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the security and privacy of online transactions by ensuring only necessary information is shared, minimizing data hijacking risks, and providing granular access control over personal data, while maintaining the user's identity anonymous to service providers.
Implementation Method 1
A plurality of pictures of the iris of the person are captured during the period of time and used to determine whether the person is live based on the captured plurality of pictures of the iris of the person.
Data Source
AI summary
The present teaching relates to method, system, medium, and implementations for authenticating a user. An authentication session is initiated to authenticate, via iris, a person claiming to be an authorized user. A trajectory is determined with respect to a display visible to the person. A plurality of focus dots are generated with corresponding coordinates on the trajectory with respect to the display and rendered to the person on the display in accordance with the corresponding coordinates during a specified period of time. A plurality of pictures of the iris of the person are captured during the period of time and used to determine whether the person is live based on the captured plurality of pictures of the iris of the person.
