Wearable Biometric Device Preauthorization for Seamless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication methods often require repeated user verification, leading to inconvenience and security trade-offs between accuracy and convenience, especially in daily interactions with multiple access points.
Innovation Solution
A wearable biometric device that captures unique biometric features, such as an electrocardiogram, and syncs with an authorized authentication device for preauthorization, allowing seamless access to various systems and devices through a control signal, reducing the need for repeated authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated biometric authentication is required for each access point, then security is improved, but user convenience deteriorates due to cumulative friction
Solution Approach 1:
The system performs preliminary biometric authentication to generate a time-limited authorization token that allows multiple subsequent accesses without repeated authentication. The wearable device captures biometric data, processes it through encryption and hashing algorithms, and stores the resulting authorization token locally, enabling frictionless re-access within the validity period while maintaining security through the pre-established cryptographic verification mechanism.
2Speed
If biometric data is stored locally on the wearable device, then authentication speed is improved, but security risk increases due to potential device theft or copying
Solution Approach 1:
The system transforms biometric data through multiple cryptographic parameter changes including encryption with device-specific keys, hashing with salt values, and generation of derived authentication credentials. The original biometric template is never stored in plaintext; instead, only cryptographic transformations are retained on the device, making stolen data unusable for direct authentication while enabling fast verification through cryptographic comparison.
3Adaptability or versatility
If multiple physical authentication items are carried, then access to different systems is improved, but portability deteriorates due to increased weight and bulk
Solution Approach 1:
The wearable device implements a universal authentication mechanism that works across multiple access points and systems using the same biometric credential. A single authorization token generated from the biometric data can authenticate the user to various locked resources including computers, smartphones, and physical access points, replacing the need for multiple separate authentication items while maintaining broad system compatibility through standardized verification protocols.

AI summary
Embodiments are directed towards authenticating users using biometric devices. The biometric device may be arranged to capture one or more biometric feature of a user that may be wearing the biometric device such as biometric features that correspond to an electrocardiogram of the user. The user of the biometric device may be authenticated based on one or more biometric features, or a combination thereof. Authenticating the user of the biometric device, may include communicating information that includes biometric features to an authorized authentication device (AAD). When the user is authenticated, the biometric device may be preauthorized for the user. When the preauthorized biometric device senses at least one access point, an authorization signal may be provided to the access point. If the preauthorized biometric device is removed from the user, the biometric device is deauthorized, disabling access to access points by the user.
