Passcode Generation via Episodic Memory Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in creating reliable, easy-to-remember passcodes that meet security requirements due to the increasing demand for unique passwords and login information, with existing methods failing to effectively leverage cognitive memory for improved memorability and security.
Innovation Solution
A system that utilizes episodic memory by presenting users with images or graphic narratives to generate passcodes, allowing users to construct memorable and secure login information by manipulating and combining images, thereby reducing the need for users to generate randomness and entropy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users create passcodes manually to meet security requirements, then passcode security is improved, but user ability to remember the passcode deteriorates
Solution Approach 1:
The patent introduces an intermediary system that generates passcodes based on user-selected images and personal information. This intermediary automatically creates secure passcodes that users can remember through their personal connection to the images, resolving the contradiction between security and memorability by mediating between security requirements and user cognitive limitations
Solution Approach 2:
The system enables users to create their own memorable passcodes by selecting images from their photo library and answering personal questions. The passcode generation process is self-service, leveraging the user's own personal information and preferences to create secure yet memorable credentials without requiring external assistance or complex manual creation
2Reliability
If users are required to create unique passcodes frequently, then security is improved, but user burden increases
Solution Approach 1:
The patent implements preliminary action by having users select and save their preferred images and personal information in advance within the system. When passcode creation is needed, the system quickly generates secure passcodes using these pre-selected elements, dramatically reducing the time required for frequent passcode updates while maintaining security through unique generation each time
3Reliability
If complex passcodes are used to meet entropy requirements, then passcode strength is improved, but ease of remembering deteriorates
Solution Approach 1:
The patent applies parameter changes by transforming the basis of passcode strength from complex character sequences to combinations of user-selected images and personal information. The system maintains entropy requirements through the mathematical properties of image selection and personal data combination, while the passcode recall ability improves because users can visually recognize and remember their chosen images and personal answers much more easily than random character strings
