Wearable Device Multi-Factor Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems for physical and electronic keys are vulnerable due to reliance on single master keys, which can be compromised, leading to access issues and security breaches if lost or stolen, and do not effectively integrate multi-factor authentication across all types of keys.
Innovation Solution
A wearable device providing multi-factor security through biometric authentication, combining possession, identity verification, and optional additional validation methods, such as passwords or complex motions, to securely manage and validate cybernetic, electronic, and physical keys, ensuring secure access and preventing unauthorized use even if the device is lost or stolen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single master key is used to store multiple electronic keys, then convenience is improved by eliminating the need to carry multiple key fobs, but security deteriorates because possession of the master key provides access to all electronic locks and if the master key is lost or stolen, an outside party may have access to all electronic locks
Solution Approach 1:
The patent divides the security system into multiple independent authentication factors (biometric data, passwords, PINs) stored separately in the password vault, rather than relying on a single master key. Each factor provides a layer of security, and compromise of one factor does not necessarily compromise all access controls.
Solution Approach 2:
The system changes the security parameter from single-factor master key authentication to multi-factor authentication, requiring multiple different types of verification (biometric, knowledge-based) to access electronic keys, thereby increasing security without significantly impacting convenience.
2Reliability
If traditional physical keys are used, then security is maintained through possession of the key, but vulnerability increases because if the physical key is lost or stolen, not only is access limited but an outside party may have access to house, car or office
Solution Approach 1:
The patent replaces mechanical key systems with electronic authentication systems that use biometric data and cryptographic verification. Instead of relying on physical possession of a key, the system uses digital authentication methods that can detect and prevent unauthorized access even if the authentication device is lost or stolen.
Solution Approach 2:
The system creates digital copies of authentication factors (biometric templates, encrypted passwords) that can be verified without physical contact or transfer, eliminating the need for physical key exchange and reducing vulnerability to theft through copying or duplication.
3Ease of operation
If cybernetic keys such as passwords are used for ease in remembrance, then convenience is improved, but security deteriorates because such passwords may be easily determined and/or hacked, and use of the same password over multiple accounts may leave such accounts compromised
Solution Approach 1:
The patent introduces a password vault as an intermediary system that manages and secures multiple passwords. Instead of users directly managing multiple passwords, the vault acts as a secure repository that can provide authentication credentials without requiring users to remember or manually handle each password, reducing the security risks of password reuse while maintaining convenience.
4Reliability
If master password services are used to provide unique hard to hack passwords stored in an encrypted password vault, then security is improved for password management, but vulnerability increases because if the master key is compromised, all passwords may need changing, and a sole master password provides a point of weakness
Solution Approach 1:
The patent segments the authentication process into multiple independent factors (biometric authentication, multiple password types, PINs) rather than relying on a single master password. The password vault stores different types of authentication credentials that can be used independently or in combination, so compromise of one factor does not necessarily compromise the entire security system.
Data Source
AI summary
A wearable device having one or more processors configured to receive one or more signals representative of biometric parameter(s) and sensed presence of a user. The one or more processors configured to compare the biometric parameter to a stored user parameter for authentication of the user. Upon authentication, the one or more processors switch from a locked mode to an unlocked mode to enable communication.
