Dynamic Mobile Authentication via Motion Pattern Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication systems require frequent re-authentication based on predetermined time periods, leading to decreased user experience and increased security risks due to the use of static passwords/pin codes that can be compromised by unauthorized users.
Innovation Solution
A method that utilizes current and historical movement, time, and location data to dynamically adjust mobile device security, requiring re-authentication only when necessary, by comparing user activity to a prediction model to assess security threats and adjust authentication levels accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systems require users to re-authenticate after a predetermined time period, then security is maintained through regular authentication, but user experience deteriorates due to frequent unnecessary re-authentication
Solution Approach 1:
The patent implements dynamic authentication by adjusting re-authentication requirements based on real-time device state analysis. Instead of fixed time-based re-authentication, the system continuously monitors device characteristics, location, and usage patterns to dynamically determine when authentication is actually needed, making the authentication frequency adaptive rather than static
Solution Approach 2:
The system changes the parameter of authentication timing from a fixed predetermined time period to a variable interval based on security risk assessment. By analyzing multiple parameters (device state, location consistency, usage patterns), the system adjusts the re-authentication interval to optimize both security and user convenience
2Adaptability or versatility
If conventional systems use passwords and pin codes for authentication, then users can access content on multiple devices and locations, but security deteriorates as unauthorized users may learn these credentials
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a sensor-based device state analysis system. Instead of relying on secret credentials that can be compromised, the system uses physical sensors (accelerometers, gyroscopes, location services) to create a unique behavioral fingerprint for each authorized device, making credential theft ineffective
Solution Approach 2:
The system introduces an intermediary layer of device state analysis between the user and content access. Rather than directly verifying passwords, the system analyzes intermediate data points (device movements, location patterns, usage behaviors) to indirectly verify device ownership and authorization, adding a security layer that cannot be easily bypassed
3Reliability
If conventional systems require constant re-authentication via password/pin code, then security is maintained, but time is lost due to repeated authentication requirements
Solution Approach 1:
The system performs preliminary device state analysis and security risk assessment in the background before re-authentication is needed. By pre-evaluating device characteristics and usage patterns, the system can predict whether re-authentication will be necessary, avoiding unnecessary authentication prompts and reducing user time loss
Data Source
AI summary
Methods and systems are described herein for an improved mechanism for authenticating users. In particular, the methods and systems facilitate variable authentication of users on mobile devices based on current and historical physical movement of the mobile devices at geographic locations and during predetermined time intervals while maintaining user privacy. Specifically, methods and systems authenticate users by comparing current motion data to historical motion data to determine if a user must be re-authenticated. For example, current motion data may be inconsistent with historical motion data and may cause re-authentication of a user. As another example, current motion data may be consistent with historical motion data and may not require re-authentication of a user. Moreover, the methods and systems alleviate privacy concerns by not transmitting sensitive data over one or more wired or wireless networks.
