Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a modern, nomadic work environment, there is a growing need for secure authentication of devices and access to sensitive information, particularly in public places, where mobile devices are frequently used, and ensuring only authorized employees can access work terminals and specific information, while preventing information leaks.
Innovation Solution
An authentication apparatus that includes a memory to store information about devices and their vicinity, a receiving unit to gather information during authentication requests, and an authentication unit that verifies devices based on stored and received information, using a device information table to associate and authenticate devices through communication lines, including wireless and wired connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device authentication is performed based on traditional methods, then authentication process is simple, but security against unauthorized access is insufficient
Solution Approach 1:
The authentication process is divided into multiple independent verification stages: first verifying the device identifier, then verifying the device name, and finally verifying the device icon. Each stage operates independently and contributes to the overall security without requiring all steps to be complex, thus improving reliability while managing complexity through modular verification.
Solution Approach 2:
The patent transitions from traditional single-dimension authentication (e.g., only password or only device ID) to multi-dimensional authentication by incorporating multiple verification dimensions: device identifier verification, device name verification, and device icon verification. This dimensional expansion significantly enhances security without making the overall process unintelligible, as each dimension provides a separate verification layer.
2Measurement precision
If multiple verification items are added to authentication process, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary verification of the device identifier first, which is the most critical and quickest verification step. By establishing the basic device identity before proceeding to more time-consuming verifications of device name and icon, the system minimizes the impact of multi-verification on total processing time while maintaining high accuracy through sequential verification of multiple attributes.
Solution Approach 2:
The patent implements verification of multiple items (device identifier, device name, device icon) which may be more than strictly necessary (excessive action). This ensures high authentication accuracy by cross-validating multiple attributes, and the system is designed to handle this multi-step process efficiently, accepting that some time is required for thorough verification but managing it through optimized sequential processing.
3Object-affected harmful factors
If device information is stored and verified, then unauthorized access is prevented, but information storage requirements increase
Solution Approach 1:
The patent stores and verifies specific local attributes of the device (device identifier, device name, device icon) rather than requiring storage of all possible device information. By focusing verification on these key local qualities that are sufficient for authentication purposes, the system prevents unauthorized access while minimizing the quantity of information that needs to be stored and managed.

AI summary
An information processing system includes a first device and a second device that is configured to perform a short-range wireless communication with the first device. In a case where the first device requests an external authentication apparatus for authentication, the first device sends information regarding the second device to the external authentication apparatus.
