Mobile Device Case with Microcontroller for Secure Data Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices are vulnerable to malware attacks during secure data entry, such as online banking transactions, as malware can intercept and alter user input, compromising privacy and security.
Innovation Solution
A mobile device case equipped with a microcontroller, communication module, and user interface that processes and securely communicates user data without the mobile device being able to interpret it, using visual indicators and touch mechanisms to conceal input from malware, and optionally integrating a smartcard reader for additional security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a CAP reader is used for secure data entry, then security is improved, but device complexity and portability are worsened
Solution Approach 1:
The patent merges the CAP reader functionality directly into the mobile device case, combining what were previously separate devices (mobile phone and CAP reader) into a single integrated unit. The case includes a microcontroller, user interface, and communication module that enable secure data entry without requiring a separate CAP reader device.
Solution Approach 2:
The mobile device case is designed to perform multiple functions: it provides physical protection for the device, enables secure data entry through its integrated user interface, and facilitates secure communication through its microcontroller and communication module. This multi-functionality eliminates the need for separate dedicated security devices.
2Reliability
If a CAP reader is carried separately from the mobile device, then security is improved, but ease of operation is worsened
Solution Approach 1:
By integrating the CAP reader functionality into the mobile device case, users no longer need to carry and switch between separate devices. The secure data entry function is always available when the device is in hand, improving convenience while maintaining security.
3Ease of operation
If user data is processed on the mobile device, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent introduces a dedicated microcontroller in the case as an intermediary between the user interface and the mobile device. This microcontroller processes and protects user data locally within the case, acting as a security barrier that prevents malware on the mobile device from accessing sensitive information while still enabling smooth user interaction.
