Input Processing System Using Segmented Data Storage for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input processing systems face security risks as they store information about input destinations and the information to be input together, making it possible to determine the usage of the input information, and previous solutions like storing passwords on external devices for short-distance communication are vulnerable to analysis.
Innovation Solution
An input processing system that separates the storage of input information and identification information, using a wrist terminal for secure storage of input information, ensuring that only the identification information is transmitted and used for input processing, thereby preventing unauthorized access to the input information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If input information and identification information are stored together in the same device, then input processing is simplified and more convenient, but security is compromised as the usage of input information can be determined
Solution Approach 1:
The patent divides the storage system into two separate components: an information storage device that stores input information (such as passwords) and an information processing device that stores and transmits identification information. This segmentation prevents the concentration of both data types in one location, thereby maintaining security while enabling automated input processing through the coordination between the two devices.
2Reliability
If input information is stored in an external device for short-distance communication, then security is improved by separating storage locations, but the system becomes vulnerable to analysis attacks on the external device
Solution Approach 1:
The patent extracts the critical input information (such as passwords) from the information processing device and stores it exclusively in the separate information storage device. Only identification information remains in the processing device, which is transmitted to the external device for verification. This extraction minimizes the security risk associated with external device analysis while maintaining the benefits of separated storage.
3Adaptability or versatility
If both mobile communication terminal and personal information transmitter store the password, then input functionality is enabled, but the risk of information specification increases if either device is analyzed
Solution Approach 1:
The patent segments the password storage function from the communication terminal by implementing a dedicated information storage device. The mobile communication terminal retains only identification information for transmission, while the actual input information remains secured in the separate storage device. This segmentation maintains input functionality through coordinated operation while reducing the information specification risk associated with analyzing either device individually.
