Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing authentication methods for portable information terminals are cumbersome and insecure, particularly when users attempt to authenticate friends for social network services, as they require manual input of identification information, which is prone to errors and does not ensure secure authentication.

Innovation Solution

A server system that uses position and operation information from terminals to determine if users are in close proximity and performing matching actions, allowing for secure and simplified friend authentication by registering users as friends when both conditions are met, utilizing a registration manager to manage user information based on position and operation data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mutual input of counterpart identification information is used for authentication, then authentication can be performed between users, but the operation becomes cumbersome and error-prone

Engineering Contradiction:

Improveauthentication accuracyVSAvoidauthentication operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automatically performs authentication by detecting position information and operation information from terminals without requiring users to manually input identification information. The server autonomously determines whether authentication conditions are met based on the detected data, eliminating the need for user intervention in the authentication process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical input method (manual typing of identification information) with an automated detection system that uses position information and operation information. This substitution eliminates manual operations while maintaining authentication security through automated verification of spatial and operational parameters.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If simplified authentication scheme is used, then operation becomes easier, but security and reliability of authentication deteriorates

Engineering Contradiction:

Improveauthentication operationVSAvoidauthentication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent adds new dimensions to authentication by incorporating position information (spatial dimension) and operation information (temporal/behavioral dimension) beyond traditional identification input. This multi-dimensional verification approach maintains security while simplifying user operations, as the system automatically checks multiple parameters simultaneously.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system uses feedback from position information detection and operation information detection to automatically verify authentication conditions. The server continuously monitors whether terminals are in proximity and whether prescribed operations are performed, using this feedback to determine authentication outcomes without requiring manual identification input from users.

Inventive Principle:

Principle #23Feedback

3Reliability

If manual input of identification information is required, then authentication can be performed, but time consumption and operation complexity increase

Engineering Contradiction:

Improveauthentication functionVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of position information and operation information automatically before authentication is needed. By continuously monitoring terminal positions and operations, the system prepares authentication data in advance, so when authentication is required, the verification can be completed instantly without requiring users to manually input information.

Inventive Principle:

Principle #10Preliminary action

AI summary

A server which can communicate with a plurality of terminals includes an information obtaining unit obtaining position information of each terminal and operation information on an operation onto an operation unit provided on a surface of each terminal, a position determination unit determining whether obtained position information of one terminal and position information of at least one other terminal satisfy a first prescribed condition, an operation determination unit determining whether obtained operation information of one terminal and operation information of at least one other terminal satisfy a second prescribed condition, and a registration manager having information on a user of one terminal and information on a user of at least one other terminal registered in correspondence with each other when both of the first prescribed condition and the second prescribed condition are satisfied.
