Dynamic Segmented Authentication Interface for Secure Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Authentication information entered on electronic displays can be easily observed by unauthorized users, posing a security risk as it is visible on devices like TVs and tablets, making existing methods for restricting access inadequate.
Innovation Solution
A system that provides a plurality of selectable regions on a display, where only one region includes a portion of authentication information, and updates the regions dynamically as the user inputs the information, ensuring that only the correct sequence of characters is entered, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication information is displayed on an electronic display for user input, then the user can easily enter the information, but unauthorized users can observe and steal the authentication information
Solution Approach 1:
The authentication input interface is segmented into multiple selectable regions, where each region corresponds to a specific character or portion of authentication information. Only one region at a time displays the correct character, forcing the user to select from multiple options rather than typing visible characters. This segmentation prevents unauthorized observers from seeing the complete authentication information while maintaining ease of input through visual selection.
2Productivity
If multiple characters are displayed simultaneously for selection, then the user can quickly input authentication information, but the authentication information becomes more susceptible to observation
Solution Approach 1:
The display dynamically updates the selectable regions based on user selection. After each selection, the system transitions to the next character position and refreshes the available options, ensuring that the authentication information changes over time. This dynamic behavior prevents static observation and photography while maintaining quick input through sequential selection from updated options.
Solution Approach 2:
The system pre-prepares multiple selectable regions with possible character options before the user needs to input authentication information. By having the correct character already positioned in a selectable region and preparing subsequent options in advance, the system enables rapid input without requiring the user to search or type, while still protecting the authentication information through the selection interface.

AI summary
Methods and systems are provided for authenticating a user for access to restricted content. An exemplary method involves providing a plurality of selectable regions on a display, authenticating the user based at least in part on a user input that corresponds to a selectable region that includes a portion of authentication information, and providing the restricted content to the display after authenticating the user. Each selectable input region of the plurality of selectable regions includes a plurality of characters. In exemplary embodiments, the characters of one or more selectable input regions are randomized.
