Content-Based Authentication System for Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional user login methods often result in users being locked out of their devices due to forgotten identifiers or passwords, leading to difficulties in accessing system data.
Innovation Solution
A content-based authentication system that presents users with familiar and unfamiliar content items, allowing them to differentiate between the two to authenticate, thereby granting access to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional login methods (user identifiers and passwords) are used, then user login security is maintained, but users may be locked out due to forgotten credentials
Solution Approach 1:
The system creates a copy of the authentication process that bypasses traditional credentials. Instead of verifying passwords, the system presents content items from the device's storage and verifies user knowledge of these items, effectively copying the authentication function through a different mechanism that avoids credential forgetfulness
Solution Approach 2:
Content items stored on the device serve as an intermediary between the user and the authentication system. Rather than directly verifying passwords, the system uses familiar content items as a mediator to verify user identity through their knowledge of these items, resolving the contradiction between security and ease of access
2Ease of operation
If content-based authentication is implemented, then users can authenticate without traditional passwords, but the authentication process becomes more complex
Solution Approach 1:
The system leverages content items that already exist on the user's device, making the authentication process self-service. The device itself provides the authentication material (content items) without requiring external verification systems, simplifying the overall process despite the novel approach
Solution Approach 2:
Content items are pre-stored on the device during normal operation, preparing authentication material in advance. When authentication is needed, these pre-positioned items are immediately available for verification, eliminating the need for complex real-time generation or external retrieval processes
Data Source
AI summary
An approach is disclosed that presents, to a user of a device, content items accessible from the device with the content items being identified as familiar to an actual user of the device. In addition, one or more comparable items are also presented with the comparable items being identified as unfamiliar to the actual user of the device. A response is received from the user at the device that differentiates the content items the comparable items with the user being authenticated, or not, based on the response.
