Dynamic Password Identity Recovery with Biometric Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for user authentication are vulnerable to security breaches and do not provide a secure method for managing user identities, particularly in combating identity theft and ensuring secure login processes.
Innovation Solution
The implementation of a blockchain-based identity management system that uses dynamic passwords, biometrics, and secure envelopes to authenticate users, eliminating the need for traditional usernames and passwords, and ensures secure data encryption and decryption, with the blockchain acting as an immutable source of truth for identity certifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional username and password systems are used for authentication, then ease of operation is improved, but security is worsened due to vulnerability to security breaches and identity theft
Solution Approach 1:
The authentication system is segmented into multiple independent components: biometric data (fingerprint, face, iris), identity proofs (government ID, passport), and behavioral verification (liveness detection). Each component operates independently and contributes to the overall authentication decision, eliminating reliance on a single vulnerable password system while maintaining user-friendly operation through automatic biometric capture.
Solution Approach 2:
A trusted third-party verification system acts as an intermediary between the user and the service provider. This intermediary performs liveness detection, validates biometric data against stored templates, and verifies identity documents through OCR and database checking, thereby enhancing security without requiring users to manually manage complex authentication credentials.
2Reliability
If multi-factor authentication with biometrics and identity proofs is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The authentication system integrates multiple verification functions into a single unified process. The device simultaneously performs biometric capture (fingerprint sensor, camera for face/iris), liveness detection through challenge-response interactions, document scanning via OCR, and database verification, all through one authentication interface that adapts to different user needs without requiring separate systems for each verification method.
Solution Approach 2:
The system performs automatic verification tasks without user intervention. Liveness detection automatically challenges the user (e.g., blink detection, head movement), biometric templates are automatically compared against stored references, identity documents are automatically scanned and validated through OCR, and the authentication decision is automatically made based on aggregated verification results, eliminating manual complexity from the user experience.
3Reliability
If dynamic passwords are used instead of static passwords, then security is improved through immediate revocation, but ease of operation is worsened due to additional user input requirements
Solution Approach 1:
The manual password entry mechanism is replaced with automatic biometric authentication. Instead of requiring users to type dynamic passwords that change frequently, the system captures biometric data (fingerprint, facial recognition, iris scan) and performs verification automatically, providing the security benefits of dynamic credentials while eliminating the operational burden of manual input.
Solution Approach 2:
Biometric templates and identity verification data are pre-captured and stored during account setup. During authentication, the system only needs to compare current biometric data against these pre-stored templates and verify liveness through automated challenges, eliminating the need for users to manually enter or remember dynamic passwords while maintaining immediate revocation capabilities through template updates.
Data Source
AI summary
A method for recovering data. Identity factors are collected at a device, wherein hashes of the identity factors are configured to be stored at a server. A dynamic password is generated at the device based on the identity factors and a Salt generated by the server and configured to be delivered to the device. A selfie is captured of a user. The device generates a symmetric key used to encrypt the selfie. The symmetric key is encrypted using the dynamic password. The encrypted symmetric key and the encrypted selfie are stored on the server. One or more data items are stored on the server. The dynamic password is recoverable by presenting the plurality of identity factors that are hashed to the server. The symmetric key is recoverable using the recovered dynamic password. The data items are recoverable by presenting the symmetric key and a second selfie of the user.
