Touch Keypad PIN Pattern Secure Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PIN and pattern-based security methods for devices are limited, as PIN-based security can be compromised through guessing and pattern-based security restricts combinations, leading to a need for enhanced security measures.
Innovation Solution
A touch-based keypad system that combines PIN and pattern inputs, where each dot represents a number and dragging between dots forms a pattern, creating a secure code stored as a combination of numbers and patterns for device access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If PIN based security is used, then the security implementation is simple, but the security level is low as it can be compromised through guessing or hit and trial methods
Solution Approach 1:
The patent combines two different authentication methods (PIN-based security and pattern-based security) into a single unified authentication system. The secure code requires both a numerical PIN and a graphical pattern to be entered correctly, merging the simplicity of PIN entry with the complexity of pattern recognition to achieve enhanced security while maintaining ease of implementation
Solution Approach 2:
The secure code functions as a composite authentication mechanism, combining two distinct authentication elements (numerical PIN and graphical pattern) into one integrated security system. This composite approach leverages the strengths of both methods while mitigating their individual weaknesses, creating a more robust security solution
2Device complexity
If traditional pattern based security is used, then the security complexity is reduced, but the maximum combination is limited to 15,120 which is insufficient for high security requirements
Solution Approach 1:
The patent merges traditional pattern-based security with PIN-based security to overcome the limitation of finite pattern combinations. By combining the graphical pattern (with its visual recognition advantages) with a numerical PIN (which can have virtually unlimited combinations), the system achieves both ease of use and high security strength
Solution Approach 2:
The patent adds a new dimension to pattern-based security by incorporating numerical PIN entry alongside the graphical pattern. This dimensional expansion transforms the authentication system from a two-dimensional graphical interface to a multi-dimensional authentication mechanism that includes both visual and numerical components, vastly increasing the security space

AI summary
The present disclosure discloses methods and systems for providing enhanced level of security for devices and/or applications on the devices. The method includes receiving a request from a user for setting a secure code as PIN with pattern option for accessing a device, for example. Then, a touch based keypad having a series of dots is displayed, each dot is associated with a pre-defined number. The secure code as input by the user is received, wherein the secure code is a combination of PIN and pattern. Then, the secure code is stored in the form of numbers along with pattern for the user. Thereafter, a request for accessing the device is received. The user is prompted to input a secure code. The secure code input by the user is matched with the stored secure code. Based on the matching, the user is allowed to access the device.
