3D Rotatable Object for Secure Graphical Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical access control techniques are vulnerable to security breaches due to easily discernible two-dimensional static patterns, which can be compromised by casual observers.
Innovation Solution
A three-dimensionally rendered object is displayed on a computing device, allowing users to select a secret sequence of visual indicia by rotating the object, with only a subset of indicia visible at any angle, enhancing security by requiring user interaction to reveal hidden elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional static images are used for graphical access control, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent transitions from two-dimensional static images to three-dimensionally rendered objects that can be rotated and viewed from multiple angles. This dimensional change allows the secret sequence to be hidden on surfaces not visible from the default viewpoint, making it much harder for observers to discern the access code while maintaining user-friendly interaction through touch or gesture-based rotation.
Solution Approach 2:
The patent introduces dynamic interaction by allowing users to rotate the three-dimensional object to reveal different faces and visual indicia. This dynamic element means the secret sequence is not statically visible but requires active user engagement to reveal, preventing casual observation while keeping the interface intuitive and easy to operate.
2Ease of operation
If all visual indicia are visible at once, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent applies local quality by placing different visual indicia on different faces of the three-dimensional object. Only the indicia on the currently visible face are displayed, while other indicia remain hidden on unseen faces. This localized visibility ensures that users can easily operate with the visible options while preventing observers from seeing the complete secret sequence.
Solution Approach 2:
The patent segments the visual indicia across multiple faces of the three-dimensional object rather than displaying them all on a single face. This segmentation distributes the secret code elements across different spatial locations that require rotation to access, making it difficult for observers to capture the complete sequence in a single view while maintaining ease of operation for authenticated users.

AI summary
A computer-implemented method for controlling access to a computing device entails displaying a user-rotatable three-dimensionally rendered object on a display of the computing device, the object presenting a plurality of user-selectable visual indicia such that only a subset of the indicia are visible at any one angle of rotation and providing access to the computing device based on user input received in relation to at least one of the visual indicia. The object may be spherical or polyhedral or it may be composed of a plurality of independently rotatable rings that together form a generally spherical shape. The visual indicia may be letters, numbers, symbols, colours, photographs or any other visually distinctive indication.
