Slider Authenticator for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone authentication methods are inadequate for devices with slider components, as they do not effectively utilize the translational movement of slider components for secure user authentication, potentially compromising data protection.
Innovation Solution
A method of authentication that involves receiving a candidate sequence of movements of a slider component relative to another component, comparing it to a previously established template sequence, and controlling access to the device based on a match, utilizing a processor and secure storage to ensure confidentiality and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used for smartphones with slider components, then the authentication process is simple and compatible with existing systems, but the security and data protection are inadequate
Solution Approach 1:
The patent transforms the static slider component into a dynamic authentication input device by tracking its translational movements across different positions. The system monitors the sequence, speed, and pattern of slider movements to create a behavioral biometric template, converting a simple UI element into a sophisticated security input mechanism without requiring additional hardware
Solution Approach 2:
The patent adds a temporal and spatial dimension to authentication by analyzing the slider's movement trajectory, speed variations, and pause durations across multiple positions. This transforms traditional 1D password entry into multi-dimensional behavioral analysis, capturing unique user movement patterns that are difficult to replicate
2Reliability
If complex authentication sequences with precise movements and pauses are implemented, then security is enhanced, but ease of operation decreases
Solution Approach 1:
The system performs self-calibration by automatically establishing the user's movement template during initial setup and subsequent usage. The authentication process requires users to simply perform their natural slider interactions without following complex instructions, as the system adapts to and learns their unique movement patterns, making security transparent to the user
Data Source
AI summary
For a device with a slider component, movement of the slider component may be used as part of an authentication process, for example, when unlocking the device, or a portion thereof, or providing user authentication to an application executed on the device.
