Color Key Password Interface for Mobile Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing accessibility of cellular devices to the internet poses a significant risk of unauthorized access and data theft due to simple password systems, as hackers can easily exploit existing alphanumeric and alpha-numeric password structures.
Innovation Solution
The integration of a color keyboard feature on mobile devices, where a lock key triggers a display of color keys, allowing users to create more complex passwords by combining letters, numbers, and symbols with color choices, enhancing password security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alphanumeric password systems are used, then ease of operation is maintained, but security reliability deteriorates due to simple password structures being easily exploited by hackers
Solution Approach 1:
The patent extends the traditional one-dimensional alphanumeric password system by adding a color dimension. Each key on the keyboard is assigned multiple colors, and passwords are created by specifying both the key and the color sequence. This transforms passwords from simple character sequences into multi-dimensional color-key combinations, dramatically increasing the password space and security reliability while maintaining ease of operation through the intuitive color-selection interface.
2Reliability
If password length is increased to improve security, then reliability improves, but ease of operation deteriorates due to longer and more complex passwords being harder to remember and enter
Solution Approach 1:
The patent changes the fundamental parameters of password construction by introducing color as an additional parameter alongside key selection. Instead of requiring longer alphanumeric sequences, the system achieves equivalent or superior security with shorter passwords by utilizing the combinatorial possibilities of key-color pairs. The color parameter provides an intuitive visual distinction that aids memory, allowing users to recall shorter color-key sequences more easily than traditional long alphanumeric passwords.
3Reliability
If more keyboard options are provided to increase password complexity, then reliability improves, but device complexity increases due to additional hardware components required
Solution Approach 1:
The patent makes the existing keyboard multi-functional by assigning multiple colors to each key rather than adding separate physical keys for each password character. The same physical keyboard serves both traditional text input and enhanced security password creation functions. This universal approach allows the device to achieve improved password security through software-based color overlay on existing hardware, avoiding the need for additional complex keyboard structures or specialized input devices.

AI summary
The usage of a new key on an existing keyboard that would have the symbol of a lock on it that when used in conjunction with other keys, such as, an alphabetical key, a number key, a symbol key, and/or an alpha character key when clicked would result in showing a color keyboard on an existing cellular telephone or mobile device would help the user or owner of the telephone to create or type a complicated password to gain access to the various functions of the cellular device.
