Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing password security enhancement methods uniformly calculate password safety, leading to excessive or insufficient security demands based on the password's duration, failing to balance convenience and safety effectively.
Innovation Solution
A computing device and method that calculates and presents the 'useful number-of-days' of a password using a specific calculation formula, considering the number of search candidates, search speed, and safety coefficient, allowing users to set passwords compatible with both convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a uniform predetermined computation formula is used to calculate password safety, then the calculation process is simple, but the safety demand becomes excessive for short-term passwords or insufficient for long-term passwords
Solution Approach 1:
The patent applies dynamics by making the password safety calculation adaptive rather than static. The calculation unit dynamically adjusts the safety assessment based on the intended usage period input by the user. For short-term passwords, the system accepts lower safety thresholds, while for long-term passwords, it demands higher safety levels. This dynamic adjustment resolves the contradiction by allowing the same simple calculation process to produce context-appropriate safety demands.
Solution Approach 2:
The patent changes the parameter of safety threshold based on the usage period parameter. Instead of using a fixed safety threshold in the computation formula, the system modifies the threshold parameter according to how long the password is intended to be used. This parameter change allows the uniform calculation formula to produce differentiated safety assessments appropriate for different usage scenarios.
2Ease of operation
If a computation formula appropriate for short-term passwords is used, then convenience is improved, but safety is insufficient for long-term passwords
Solution Approach 1:
The system dynamically adjusts the safety threshold parameter based on the intended usage period. When users indicate they need a password for a short period, the system lowers the safety threshold, making password setting more convenient. Conversely, for long-term passwords, the system raises the threshold to ensure adequate safety. This dynamic parameter adjustment allows the same computation formula to serve both convenience and safety needs.
3Reliability
If a computation formula appropriate for long-term passwords is used, then safety is improved, but convenience deteriorates due to excessive safety demands
Solution Approach 1:
The system changes the safety threshold parameter based on the usage period input by the user. For long-term passwords, the system appropriately raises the safety threshold to ensure adequate protection. For short-term passwords, it lowers the threshold to avoid excessive demands that would reduce convenience. This parameter adaptation allows the computation formula to maintain high safety where needed while being lenient where appropriate.

AI summary
An information processing device includes a display. A password input screen for a user to input a password is displayed on the display. When the password is input on the password input screen, the useful number-of-days of the input password is calculated according to a predetermined calculation condition. When the useful number-of-days of the password is calculated, a confirmation screen for allowing the user to confirm the useful number-of-days of the calculated password is displayed on the display.
