Multi-key Password Input System Using Key-release Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional password input methods using keyboards are vulnerable to cracking due to limited bit combinations, making them insecure against hacking methods.
Innovation Solution
A password input system that groups alphanumeric symbols into multi-key input password sets based on predetermined key-releasing rules, allowing users to input multiple keys for a single password element, increasing complexity and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional keyboard password input methods are used, then the operation is simple and easy to use, but the password security is weak due to limited bit combinations
Solution Approach 1:
The patent segments a single password element into multiple key-pressing operations. Instead of inputting one character at a time, users press multiple keys (e.g., 3-5 keys) to generate one password element. This segmentation increases the bit combinations per password element from conventional limited options to multi-key combinations, thereby enhancing password security while maintaining a relatively simple input interface.
2Reliability
If multiple keys are pressed to form a single password element, then the password complexity and security are increased, but the input time and operation steps are increased
Solution Approach 1:
The patent implements periodic action by grouping key-pressing operations into fixed cycles. Each password element is formed by a predetermined number of key presses (e.g., 3-5 keys per element), creating a rhythmic and predictable input pattern. This periodic structure allows users to input passwords efficiently despite the increased complexity, as they can maintain a consistent typing pace without needing to plan each individual key press separately.

AI summary
A password input system and a method inputting a password are provided. The password input system includes a signal receiving unit, a processing unit and a storage device. The signal receiving unit receives input signals comprising key-pressing signals and key-releasing signals respectively corresponding to the key-pressing signals and each key-pressing signal corresponds to an alphanumeric symbol. The processing unit, according to a predetermined key-releasing rule, sequentially groups the alphanumeric symbols corresponding to the key-pressing signals into groups. Each group is regarded as a password element and the password elements together form a multi-key input password set. The storage device stores the multi-key input password set.
