Adaptive Authentication System for Situation-Based Input Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and security risks when repeatedly entering full authentication information for services, as omitting entry is undesirable for security but burdensome for frequent use.
Innovation Solution
An information processing apparatus that identifies current and past user situations to simplify authentication information, prompting users to input only the necessary parts, ensuring security by adjusting complexity based on situation similarity and security requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user inputs full authentication information every time, then security is ensured, but user convenience deteriorates
Solution Approach 1:
The authentication information is segmented into multiple parts based on the user's situation. The system divides the full authentication information into a first authentication information (for common situations) and a second authentication information (for specific situations), allowing users to input only necessary portions while maintaining security
Solution Approach 2:
The system dynamically adjusts the authentication information input requirements based on the user's current situation compared to past authentication situations. When situations match, the system reduces input requirements; when they differ, it adjusts accordingly, making the authentication process adaptive rather than static
2Ease of operation
If the user omits authentication information entry, then user convenience improves, but security deteriorates
Solution Approach 1:
The system applies partial action by requiring users to input only a portion of the authentication information (the second authentication information) when situations match, rather than requiring full input. This partial input is sufficient for security when combined with situation verification
Solution Approach 2:
The system uses feedback from situation comparison to determine authentication requirements. By comparing current situation with past authentication situations, the system provides feedback on what level of authentication information is needed, balancing convenience and security based on contextual feedback
3Ease of operation
If authentication information is simplified based on situation matching, then user convenience improves, but authentication security may deteriorate
Solution Approach 1:
The system applies local quality by differentiating authentication requirements based on specific situation characteristics. Different situations receive different levels of authentication simplification, with the degree of simplification localized to the specific context rather than applied uniformly
Solution Approach 2:
The system creates asymmetry in the authentication process where matching situations receive simplified authentication (requiring only second authentication information) while non-matching situations require full authentication, creating an asymmetric treatment based on situation comparison results

AI summary
It is an object to allow for simplification of authentication information to be input by a user while ensuring security. An information processing apparatus identifies a current situation in which a user is placed. The information processing apparatus obtains a past situation in which the user was placed at the time of past authentication. When the user is currently authenticated, the information processing apparatus simplifies authentication information to be entered by the user, depending on the current and past situations. The information processing apparatus outputs information prompting for the simplified authentication information.
