Proximity-Based Identity Verification for Remote Asset Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems, including passwords and biometric methods, fail to accurately validate user identity and are prone to compromise, leading to security vulnerabilities and inefficient access control, especially in scenarios requiring varying authentication strengths based on role or context.
Innovation Solution
A user identification system that utilizes a combination of motion data from sensors, such as accelerometers and gyroscopes, along with non-motion data like biometrics and environmental signals, to generate a unique identity signature for continuous authentication, incorporating machine-learning models to analyze and verify user identity with adaptive confidence thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passwords or security cards are used for authentication, then access control decisions can be made, but the systems cannot validate that the person using the credentials is in fact the user to whom the identity belongs
Solution Approach 1:
The system continuously monitors proximity between the authentication device and the user device, providing real-time feedback to verify that the authenticated user is in physical possession of the device. This ongoing verification ensures identity validity throughout the session, not just at authentication moment.
Solution Approach 2:
The patent introduces an intermediary proximity verification mechanism that mediates between the authentication credentials and the user identity. By requiring the authentication device to remain in proximity to the user device, the system creates a trusted connection that validates identity without requiring complex biometric systems.
2Productivity
If passwords or security cards are used for authentication, then access can be granted, but access is often granted for a longer period of time than is appropriate
Solution Approach 1:
The authentication session becomes dynamic rather than static. The system continuously evaluates proximity conditions during the session, automatically adjusting or revoking access based on whether the user remains in proximity with the authentication device. This enables appropriate access duration without manual intervention.
Solution Approach 2:
The system maintains continuous proximity verification throughout the authentication session rather than performing a single check at the beginning. This ongoing verification ensures that access rights are maintained only as long as the user remains in possession of the authentication device, preventing unauthorized extended access.
3Reliability
If multi-factor authentication techniques are implemented, then the difficulty required to impersonate another user increases, but additional implementation challenges arise requiring users to carry additional security cards
Solution Approach 1:
The patent makes the user's existing mobile device serve multiple security functions simultaneously. The device acts as both the authentication credential holder and the proximity verification mechanism, eliminating the need for separate security cards while maintaining multi-factor authentication security levels.
Solution Approach 2:
The system uses the user's own existing device and its sensors to provide the additional security factor. Rather than requiring the user to carry and manage separate security cards, the mobile device itself provides the proximity verification capability through its built-in sensors, making the security system self-contained and user-friendly.
4Reliability
If conventional biometric systems are implemented, then user identity validation improves, but the systems are very expensive and difficult to implement
Solution Approach 1:
The patent replaces expensive, complex biometric hardware with inexpensive software-based proximity sensing using existing mobile device sensors. The solution uses readily available accelerometers, gyroscopes, and GPS to create a cost-effective authentication system that achieves reliable identity validation without requiring specialized biometric equipment.
Solution Approach 2:
The system replaces mechanical or electronic biometric verification systems with a software-based solution using motion sensors and location data. By substituting physical biometric scanners with sensor-based proximity detection, the patent achieves identity validation with significantly reduced implementation complexity and cost.

AI summary
An identity verification system is disclosed for identifying a user based on the classification of user characteristic data. The identity verification system receives a request for access to an operational context that comprises authentication credentials representing an identity of a requesting target user. The system authenticates the identity of the requesting target user by determining an identity confidence value describing a likelihood that an identity of the requesting target user matches the identity represented by the authentication credentials. The system determines a proximity of the requesting target user to the operational context by determining a distance between a location of the requesting computing device and a location of an authenticating computing device operated by the requesting target user. The system grants the request from the requesting target user for access to the operational context if the requesting target user is within a threshold proximity of the operational context.
