Joystick Sequence Authentication for ATMs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment terminals and ATMs require users to enter PINs or zip codes for authentication, which can lead to inefficiencies and security breaches due to forgetfulness or easy compromise of personal information.
Innovation Solution
Implementing a joystick-based authentication system where users input a joystick sequence, which is easier to remember and harder to copy, and is associated with their identification information, enhancing both efficiency and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PIN or zip code is used for authentication, then the authentication process is simple and familiar to users, but it is easy to be forgotten or compromised leading to security breaches
Solution Approach 1:
The patent replaces the traditional mechanical keypad input system with a joystick-based input system. Instead of pressing keys to enter PINs or zip codes, users manipulate a joystick to create authentication sequences, substituting the mechanical keypress action with continuous analog joystick movement that can be processed into digital authentication data.
Solution Approach 2:
The patent changes the authentication parameter from discrete numerical values (PIN digits 0-9) to continuous spatial-temporal patterns (joystick movement trajectories, speeds, directions, and timing). This parameter transformation creates more complex authentication data that is harder to compromise while remaining operable by users.
2Reliability
If a joystick sequence is used for authentication, then security is improved due to difficulty in copying, but the device complexity increases
Solution Approach 1:
The patent makes the joystick serve multiple functions: it acts as both the primary input device for transaction commands and the authentication input device. This multi-functionality reduces overall system complexity by eliminating the need for separate authentication hardware while enhancing security through the joystick's capability to capture complex movement patterns.
Solution Approach 2:
The system automatically processes the raw joystick movements and extracts authentication sequences without requiring additional user actions. The processor automatically captures the movement data, compares it against stored patterns, and determines authentication results, reducing the need for complex additional components.
3Ease of operation
If a joystick sequence is used for authentication, then memorability is improved for users, but the processing complexity increases
Solution Approach 1:
The system performs preliminary processing by capturing and storing multiple samples of user joystick movements during setup, then creating an averaged or representative authentication pattern. This preliminary action simplifies subsequent authentication processing by comparing new inputs against pre-processed reference patterns rather than requiring complex real-time analysis of raw movements.
Solution Approach 2:
The system incorporates feedback mechanisms where the processor analyzes joystick movement patterns and provides real-time or post-processing feedback to determine authentication success. This feedback loop allows the system to adjust processing parameters and make authentication decisions based on accumulated data, managing complexity through iterative refinement.
