Wearable Device Proximity Authentication for Seamless Multifactor Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifactor authentication methods are cumbersome for users, requiring repeated input of information across various devices and services, leading to inconvenience and potential errors in authentication processes.
Innovation Solution
A wearable device equipped with sensors and a communication module that provides authentication credentials based on user proximity and stored data, allowing for continuous authentication without user intervention until the device is removed or an event occurs, such as a software update expiration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multifactor authentication is implemented across various devices and services, then security and identity verification confidence are improved, but user convenience and operational ease deteriorate due to repeated information input requirements
Solution Approach 1:
The system performs preliminary authentication by detecting proximity between the wearable device and mobile device before actual service access is needed. Authentication credentials are obtained and validated in advance, so when the user needs to access a service, the authentication is already complete or nearly complete, eliminating the need for repeated information input.
Solution Approach 2:
The authentication system operates autonomously by automatically detecting device proximity, retrieving authentication credentials, and validating identity without requiring user intervention. The wearable device and mobile device communicate automatically, and the system self-manages the authentication process including obtaining credentials from authentication servers and determining when authentication is successful.
2Reliability
If continuous authentication monitoring is implemented to maintain security, then authentication reliability is improved, but device complexity and system resources increase
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic proximity detection through keepalive data exchange between the wearable device and mobile device. The mobile device periodically sends keepalive data to confirm the wearable device is still nearby, providing continuous authentication monitoring through discrete periodic checks rather than constant monitoring, thus reducing system complexity.
3Reliability
If authentication credentials are continuously validated across multiple devices, then security is improved, but time consumption and operational efficiency worsen due to repeated authentication requests
Solution Approach 1:
The system performs authentication in advance by detecting proximity and obtaining credentials before the user actually needs to access a protected service. This preliminary authentication ensures that when service access is required, the validation is already complete or can be quickly finalized, eliminating repeated authentication delays.
Solution Approach 2:
The authentication state is maintained continuously through periodic keepalive data exchange, allowing the authenticated state to persist across multiple service accesses without requiring re-authentication. This continuity enables seamless transitions between services while maintaining security, as the authentication credentials remain valid as long as the wearable device stays proximate to the mobile device.
Data Source
AI summary
Described are techniques and systems for providing authentication credentials associated with a user. The user is authenticated using one or more techniques, such as multi-factor authentication using one or more biometric characteristics, biomedical data, passwords, and so forth, to generate authentication data. The authentication data may be used in conjunction with information about a wearable device (“wearable”), such as a wristband. Authentication may be confirmed upon an indication that the wearable has not been removed, tampered with, and so forth. In some implementations the wearable device may store and distribute the authentication credentials to requesting devices so long as the wearable has not been removed, tampered with, and so forth.
