Solution Overview

Problem

Conventional authentication technologies face difficulties in flexibly responding to authentication requests due to the need for changing security or convenience functions, as terminal devices often lack the required functions for personal authentication, making it challenging to meet the demands of authentication servers.

Innovation Solution

A providing device that detects the necessary authentication functions not held by a user's terminal device and procures these functions from external devices, such as proxy or friend terminals, to provide them to the user's terminal, enabling communication with the authentication server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the authentication server requires specific authentication functions to ensure security, then the authentication security is improved, but the terminal device cannot perform authentication because it lacks the required functions

Engineering Contradiction:

Improveauthentication securityVSAvoidterminal device function compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The providing device acts as an intermediary between the terminal device and the authentication server. It detects which authentication functions the terminal lacks, procures these functions from external sources, and provides them to the terminal device, enabling the terminal to communicate with the authentication server without modifying the terminal's configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the authentication server changes authentication functions to meet security or convenience demands, then the authentication flexibility is improved, but the terminal device cannot adapt because its functions are fixed

Engineering Contradiction:

Improveauthentication request response flexibilityVSAvoidterminal device configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adapts to authentication requirements by having the providing device detect the terminal's current function status and procure missing functions as needed. This allows the terminal to flexibly respond to changing authentication requests without requiring configuration changes or updates to the terminal device itself.

AI summary

A providing device according to the present application includes a detecting unit and a providing unit. The detecting unit detects a function, from among functions used for communication with an authentication server that authenticates the identity of a user by verifying a signature of authentication result information that is information created by adding the signature using a predetermined key to an authentication result obtained by an authentication device that performs personal authentication on the user and that is information processed by a specific authentication procedure, that is not held by a terminal device that is used by the user. The providing unit provides the function detected by the detecting unit to the terminal device that is used by the user.
