Solution Overview
Problem
Existing solutions for securing data on portable storage devices, such as USB sticks, are inadequate in preventing unauthorized access, particularly for users working remotely or traveling who need to protect proprietary data.
Innovation Solution
A biometrics-enabled USB storage device that employs iris recognition for authentication, using a camera with a near-infrared LED and hot mirror for image capture, and a system-on-chip (SoC) with a USB controller and inertial measurement unit to manage access and detect potential theft or misuse, ensuring secure data storage without the need for third-party software on target devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password or software-based security is used on portable storage devices, then ease of operation is maintained, but security reliability is insufficient to prevent unauthorized access
Solution Approach 1:
The patent replaces traditional mechanical/software-based authentication (passwords, software keys) with a biometric authentication system using iris recognition. The camera captures iris patterns and compares them against stored templates, providing cryptographic-level security without requiring users to remember passwords or install software agents on target devices.
Solution Approach 2:
The biometric authentication system enables self-service security where the user's own biological characteristics (iris patterns) serve as the authentication mechanism. The system automatically captures and verifies biometric data without requiring third-party software or manual password entry, making security both highly reliable and easy to operate.
2Reliability
If biometric authentication systems are implemented, then security reliability is significantly improved, but device complexity increases due to additional components
Solution Approach 1:
The patent integrates multiple functions into a single portable storage device: data storage, biometric authentication, and encrypted data transmission. The iris recognition system uses a camera, LED illumination, and pattern matching algorithms all within the existing USB storage device architecture, avoiding the need for separate biometric hardware devices.
Solution Approach 2:
The patent combines the biometric authentication system directly with the portable storage device, merging the camera, processing unit, and storage functions into one integrated unit. This eliminates the need for separate authentication devices and third-party software installations, reducing overall system complexity while maintaining high security.
3Adaptability or versatility
If portable storage devices are made accessible across multiple computing devices, then adaptability is improved, but security risk increases due to potential unauthorized access
Solution Approach 1:
The patent replaces traditional software-based access control with hardware-based biometric authentication. The iris recognition system provides cryptographic security that is independent of the target computing device's operating system or software environment, allowing secure access across multiple devices without vulnerability to software-based attacks.
Solution Approach 2:
The biometric authentication system acts as an intermediary security layer between the user and the data on the portable storage device. The camera and pattern recognition algorithms serve as mediators that verify identity before allowing data access, providing security that is independent of the target device's software environment.

AI summary
A biometrics-enabled portable storage device may store and secure data via biometrics related to a user's iris. The biometrics-enabled portable storage device may include a camera that captures image data related a user's iris and stores the image data to enroll the user for use of the biometrics-enabled portable storage device. To unlock the data, a user aligns the camera with their iris using a hot mirror and the camera captures iris data for comparison with the iris image data stored during enrollment. If the two sets of image data match, the biometrics-enabled portable storage device may be unlocked and the user may access data stored on the biometrics-enabled portable storage device. If the two sets of image data do not match, then the biometrics-enabled portable storage device remains locked.
