Wearable Biometric Authentication via Retinal Scanning and DASA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user-wearable devices lack comprehensive security measures for bio-identification, communication, and data access, particularly in wireless transactions, as they often require physical contact and are vulnerable to unauthorized access if the PIN is compromised.
Innovation Solution
The development of user-wearable devices equipped with a housing, computer-driven communication processor, biometric data transceivers, and encryption capabilities that continuously authenticate and validate users through bio-identification, ensuring secure transactions and data access, even when not in use, using a distributed auto-synchronous database for secure data storage and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical contact and PIN verification are used for Smart Card transactions, then transaction security is improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical system of physical card swiping and manual PIN entry with a biometric authentication system using optical sensors to scan retinal or iris patterns. This substitution eliminates the need for physical contact and manual input while maintaining high security levels, as biometric data is inherently difficult to replicate or steal compared to PINs.
Solution Approach 2:
The patent creates a digital copy of the user's biometric characteristics (retinal or iris pattern) and stores it in encrypted form in the Smart Card and on remote servers. This biometric template serves as a unique identifier that can be quickly verified without requiring the user to physically present the card or manually enter credentials, thus improving both security and convenience.
2Reliability
If biometric data scanning is implemented for user identification, then authentication reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent integrates multiple authentication functions into a single biometric scanning mechanism. The same optical sensor can scan both retinal patterns and iris patterns, and the system can authenticate users across different devices and transactions using the stored biometric templates. This multi-functionality reduces the need for separate authentication components and simplifies the overall device architecture.
Solution Approach 2:
The patent introduces an intermediary layer of biometric template matching algorithms that bridge the gap between complex optical scanning and simple authentication decisions. The system scans biometric data, compares it against stored templates using specialized algorithms, and produces a clear authenticate/authenticate not result. This intermediary processing layer manages the complexity internally while presenting a simple user experience.
3Reliability
If continuous bio-confirmation and authentication are performed, then security against unauthorized access is improved, but energy consumption and processing load increase
Solution Approach 1:
The patent implements periodic authentication checks rather than truly continuous monitoring. The system performs bio-confirmation at scheduled intervals and triggers additional authentication events based on specific conditions such as transaction initiation or device wake-up. This periodic approach maintains security while allowing the device to enter low-power states between authentication events, significantly reducing energy consumption.
Solution Approach 2:
The patent enables the authentication system to automatically manage its own operation by monitoring device state and transaction context. The system self-determines when authentication is necessary based on predefined security policies, automatically initiating bio-confirmation only when needed rather than continuously. This self-service approach optimizes energy usage by eliminating unnecessary authentication processing while maintaining security posture.

AI summary
Described are user-wearable devices utilizing encryption authentication techniques to ensure security of any data transmission to and from these devices. In order to provide privacy and security of user-wearable device signals, unique encryption technology is employed together with the use of biometrics associated with each user. The user-wearable devices may be electronic and can include one or more circuits, power sources, displays, and transceivers with biometric data transceiver portions. The devices can establish communications with a counterpart communication device or system in order to provide the ability to perform specific secured transactions. The biometric data transceivers are capable of reading a user's encrypted biometric data and then transmitting the encrypted data to a user identity validation distributed auto-synchronous array (DASA) database which allows for decryption, identification, and authentication of both the user(s) and the transaction(s).
