Iris Liveness Detection via Synchronized Light Strobing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current internet transactions face significant security and privacy concerns due to the risk of data hijacking during the transmission of personal or private information, as existing security measures can be circumvented by emerging tools and methods.
Innovation Solution
A self-sovereign information management framework that utilizes iris-based liveness detection and cloaked identifiers to authenticate users and validate secure/private information, minimizing the transmission of sensitive data over networks and ensuring secure data access through granular control and zero-knowledge proof mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal information is transmitted over the Internet for validation, then transaction convenience is improved, but security and privacy are worsened due to data hijacking risks
Solution Approach 1:
The patent extracts and transmits only the essential validation attributes (e.g., age verification, income level) rather than complete personal information. This allows transaction convenience to be maintained while reducing security risks by removing unnecessary sensitive data from transmission.
Solution Approach 2:
The patent introduces trusted third-party validators who hold and verify personal information locally. These intermediaries provide validation certificates to users without requiring direct transmission of sensitive data over the Internet, thus maintaining transaction convenience while enhancing data security through localized verification.
2Measurement precision
If complete personal information is transmitted for validation, then validation accuracy is improved, but loss of information and privacy exposure are worsened
Solution Approach 1:
The patent extracts only the specific validation attributes needed for each transaction (e.g., age for alcohol purchase, income level for loan application) and transmits them in a structured format. This ensures validation accuracy is maintained while minimizing privacy exposure by excluding irrelevant personal information.
Solution Approach 2:
The patent applies different levels of information disclosure based on the specific validation requirements of each transaction. Sensitive information is disclosed locally to trusted validators only when necessary, while maintaining privacy protection in other contexts. This localized quality approach ensures validation accuracy where needed while reducing overall privacy exposure.
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 approach enhances user control over their data, ensures the integrity of information, and reduces the risk of data hijacking by minimizing the exposure of sensitive information during transactions, while providing trusted entities with verification attributes without access to the underlying records.
Implementation Method 1
a first set of signals is randomly generated for controlling light strobing to be applied to the iris of the person for detecting liveness of the iris
Data Source
AI summary
The present teaching relates to method, system, medium, and implementations for authenticating a user. An authentication session is first initiated to authenticate, via iris, a person claiming to be an authorized user, in which a first set of signals is randomly generated for controlling light strobing to be applied to the iris of the person for detecting liveness of the iris. A second set of signals is accordingly generated for controlling iris picture capturing synchronized with the light strobing. The light strobing is applied to the person via strobes generated based on the first set of signals and pictures of the iris of the person are acquired, based on the second set of signals, that are synchronized with the light strobing. Whether the person is live is then determined based on the synchronized pictures acquired when the light strobing is applied.
