HMD Biometric Iris Authentication for Secure Encrypted Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display (HMD) devices lack effective security measures to prevent unauthorized access to sensitive information, as traditional authentication methods like accounts and passwords can be easily compromised.
Innovation Solution
Incorporating a biometric information input unit, such as an iris camera, into the HMD to authenticate users and decrypt encrypted information using a communication module and processor that transmits biometric data to a user authentication server, obtaining access privilege information to decrypt stored information securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (account and password) are used, then the device can identify users through DB matching, but the account and password may be illegally used and are not easy to input
Solution Approach 1:
The patent replaces the mechanical input method (keyboard typing of passwords) with a biometric authentication system using an iris camera. The camera captures iris patterns and converts them into authentication data, eliminating the need for manual password input while enhancing security through unique biological characteristics.
Solution Approach 2:
The patent introduces a biometric authentication server as an intermediary that handles the complex authentication process. The HMD device sends captured biometric data to the server, which performs the matching and verification, returning authentication results to the device. This separates the authentication logic from the user interface, improving both security and ease of use.
2Adaptability or versatility
If anyone can wear the head-mounted display apparatus, then the device is easy to use by multiple users, but unauthorized users can access and see sensitive information
Solution Approach 1:
The patent implements preliminary authentication through biometric verification before allowing access to the HMD device or its content. The system captures and verifies the user's iris pattern before granting access, ensuring that only authorized individuals can use the device. This preliminary security check prevents unauthorized access while maintaining multi-user capability.
Solution Approach 2:
The patent segments the authentication process from the device access process. Instead of controlling physical device access alone, it separates authentication (biometric verification) from device operation, allowing the device to be shared while ensuring each user is properly authenticated before accessing sensitive information.
3Reliability
If encrypted information is stored in the HMD device, then security is improved, but the device needs complex decryption capabilities and key management
Solution Approach 1:
The patent extracts the complex decryption and key management functions from the HMD device and places them on the biometric authentication server. The device stores encrypted information and receives decryption keys from the server after successful authentication, rather than maintaining complex decryption capabilities locally. This reduces device complexity while maintaining security.
Solution Approach 2:
The patent uses the biometric authentication server as an intermediary to manage decryption keys and encrypted information. The server handles key distribution and decryption operations, allowing the HMD device to focus on display and user interface functions while maintaining security through centralized key management.
